I don't have much prior experience in Android Studio. I'm trying to debug a problem in C++ code. Djinni and ninja are used in the product. I know that the same setup with zero additional tweaks is debuggable at another machine.
But on mine, the debugger doesn't want to stop at C++ breakpoints at all. Sometimes it shows "no executable code is associated with this line" message. Other times the breakpoints are just plain red without a check mark.
Debugger log says the debugger is attached.
I don't see the "app/.cxx/Debug" folder, only the "Release" one (the other machine also has only "Release"). Build.ninja files contain release flags for cpp code. Via the search in all files in the project directory, I did not find the set of debug flags that are used in CMakeLists anywhere among the build artefacts.
It seems like I tried everything that I found on SO:
checked for correct build variants
checked jni debuggable true, minify enabled false, empty proguard file
tried different debug types in Run/Debug config -> Debugger (however idk which symbol directories to add manually)
tried debugging in an emulator as well as on a real device
in the emulator, uninstalled the app and did cold boot
used the same Studio version as on that other machine
used the latest Studio version, and the newest preview
cleared caches, cleaned, refreshed linked C++ projects
made clean Studio reinstall with prior deep cleaning of all Gradle and Android files via Terminal
upgraded Gradle
use the same NDK version as in build.gradle
added NDK dir to local.properties manually
tried using "make module app" instead of simple "make" command
Nothing helped so far. Only once after a crash the execution stopped and showed an assembly line with a simple call stack, without details.
I'm new for C++ and Qt.
Recently, I was learning Qt with MS SQl, but I met a problem when compiling the odbc files.
Firstly I run qmake and it goes well. But when I use nmake, the following errors happened:
module machine type 'x64' conflicts with target machine type 'x86'
I encountered similar problem just today.
Same as you,
I tried almost all comand tools include the one in qt, vs2015 x86,x64
command prompt, and cross tools as well. But none of them works.
I solved the problem by the following:
Deleted the whole project and its folder completely.
Created the project anew.
Made sure %PATH% variable, aside from irrelevant paths, contained only path to proper Qt build. In my case %PATH% contained 'C:\Qt\5.5\msvc2013_64\bin'. By proper i mean, of course, a Qt build that was built using the same compiler I was trying to compile with.
Then I ran VS2013 x64 Native Tools Command Prompt.
Switched to the project folder.
Then i did qmake and then nmake and it was all OK.
I think the problem was that, as drescherjm suggested,
If you tried one time with the wrong command prompt then tried again on the same build folder you build folder would have been broken by the bad try.
and therefore,
You will have to clean build between tries.
Thanks to drescherjm and Herman Nurlygayanov, the problem is finally solved.
Here is some experience I get from this problem:
The version of Qt creator whether 32-bit or 64-bit should be made sure before all these stuff by checking the About Qt creator. It is important to choose the right version of command prompt before compiling.
Besides, If a 32-bit command prompt is used, then vcvars32.bat should be executed. As for 64-bit version, vcvarsall.bat should be executed. They are located in %dir of you vs%/vc and %dir of you vs/vc/bin respectively.
If any error happened during one compiling, another qmake must be executed in next attemption.
I am using Eclipse Juno with MinGW (latest version) on my Win7-Laptop.
My example code is successfully built within the IDE, but I can neither run nor debug it!
When I choose Run as=>Local C/C++-Application, I get
Launch failed. Binary not found.
However, there IS an exe-file as a result of the build process!
When I call cmd.exe, navigate to the source directory and call this built exe (a.out.exe), it works without problems!
I guess this is due to wrong/missing configuration of eclipse, but I couldn't find useful info on that so far.
This thread mentions environment variables. I added MinGW and Msys to my PATH variable (that's why I can compile) but I can't run my software in eclipse!
So, what can be done to enable debugging?
I have made a little tutorial.
how to set all for Eclipse have a look it's here https://stackoverflow.com/a/12169583/1322642
Hope it can help you a little bit.
I am quite troubled as this shouldn't be causing me such a headache. I've downloaded the most recent Eclipse Indigo and all CDT C++ plugins for MAC OS X 10.7.1/
Upon restarting after installing the above CDT plugins, I've developed a simple 'hello world' c++ application and have tried running the application, "Launch failed. Binary not found." error message. I've read multiple fixes but none have worked. I tried adding the -arch i386 flag to the linker and compiler commands, still no luck.
Has anyone successfully gotten Eclipse C++ running on 10.7.1?????? This blows my mind. I can simply write the same program in VIM and compile it just fine via the terminal and execute just fine. ECLIPSE DOESN'T WANT TO PLAY ALONG.
I will be deeply indebted to anyone who can help!!!!!

I am using Eclipse Juno with CDT on a 2007 Macbook running Snow Leopard. I have the two symptoms:
No Binaries folder in Project Explorer, and
The 'Launch failed. Binary not found' error.
I have spent hours searching on Google for an answer, long enough to ascertain that these two symptoms are indicative of any number of problems which have been reported for not quite a decade without adequate resolution. That is a problem right there because after a decade there should have been more than enough input data to provide one troubleshooting procedure somewhere which walks the user step by step through the elimination of all possible causes.
Instead, for hours I have read about a multitude of people, many of whom have resolved their particular problem but all of them seeming to have had to do something slightly different to get there.
This should not be that difficult to resolve. Particularly in cases such as mine [but I am not the only one] when the Console view displays a Build with no errors yet the user can copy the binary file [which Eclipse bizarrely says it can not find] to the Desktop and run it without any problems from either Finder or a bash terminal session.
All of this seems to be pointing rather emphatically toward the lack of adequate indicators in the Mach0 64 binary parser which should be designed to tell us exactly what it needs which it is not seeing.
Admittedly, this is exacerbated in the case of MacBooks like mine which are running a 64bit OS [Snow Leopard] on a 64bit CPU which the manufacturer, unfortunately, hamstrung with a 32-bit bootup kernel. But, be forewarned, I have already tried the -arch i386 g++ switch, and the relinking of g++ to g++-4.0 without any change in the symptoms.
ADDENDUM ADDED 10/07/2012:
I am adding this checklist in the hope of clarifying a Way for the undoubtedly many others who will ask this question in the years to come. This Way reflects what I found to be necessary when using Eclipse Juno with a Mac running Snow Leopard:
1) Go to Preferences->C/C++->New CDT Project Wizard, and under Preferred Toolchains, make sure all the Executable project types are set to MacOSX GCC.
2) This is a biggie. I was able to get a Binaries folder in Project Explorer, and hence be able to run the project after building it, by using a Project name which does not contain dots ['.']. This I learned from another answer here, edited a few hours after my previous message. This requirement is easy to miss, hence a common one particularly if you are Eclipse experienced but only with other languages, because tutorials for other language plugins [such as with PyDev or for Java] frequently have you create Projects with dots in the name. If you have developed that habit with other languages, break it when using CDT for C/C++. Be forewarned, however, that it is not enough to just do a Right-Click and Rename an existing project name this time not using dots. The simplest Way is to delete your old project and create a new one with a name without dots.
3) There are many websites cautioning you to make sure you either use the -arch i386 compiler switch or change the links for /usr/bin/gcc and /usr/bin/g++ to point to gcc-4.0 and g++-4.0 instead of gcc-4.2 and g++-4.2. I created a bash script to ease switching back and forth and investigated if this was necessary. It was not, at least not with my Macbook. Based on what I read at one site from a Mach-O developer, I suspect that the current version of Mach-0 64 goes both ways. Which is a good segue to ...
4) In the Project Properties, not Preferences, go to C/C++ Build->Settings and under Binary Parsers make sure Mach-O 64 Parser is checked. Make sure this, and not the deprecated Mach-O parser, is checked.
5) At this point, after you build your project, several things should be evident in the Project Explorer:
6) There should now be a Binaries folder under project's folder.
7) Within that Binaries folder should now be your executable file. It should have [x86_64/le] next to it if, like me, your Mac is effectively 32bit. Now is not the best time to get into the confusing topic of whether your Mac is effectively 32bit or 64bit. If you do not know, and a lot folks don't because Apple does make it confusing, check out the little app which can be downloaded from http://www.ahatfullofsky.comuv.com/English/Programs/SMS/SMS.html which will tell you What Is Truth. It is free, but the 'price' is that you have to scroll pass the ads at the top of the page reflecting the programmer's political disposition.
For those of you that are new to programming/eclipse/IDEs and get the same error but the solutions above don't work, I solved my "Launch Failed. Binary Not Found." error by doing the following: Simply be sure to build your project ("Project" > "Build All") before attempting to run or debug. I was thinking that the IDE would do the building when I clicked debug or run, but that is not the case (obviously, in retrospect). Newbie lesson learned. Once you build you should see a "Binaries" and "Debug" folder under the root directory of the project.
I was using OS X 10.7.3, if it matters, though I assume the mistake I made is fundamental and any eclipse distro would give the same error.
on mac:
Make sure you have xcode installed. Test it by writing "info g++" you must see proper information about the compiler.
Build your project.
Go to the folder of your project. You should see an executable file in Debug or realise folder, depending to your building configurations. If you d-click on the executable file you should see the result on the terminal.
Back to Ecliipse, from Run/Run Configurations... and then browse to the folder that you have the executable file - one you already found - you can also change build configurations as you wish in that window. And make build automatic for each run.
Run again it should work.
Good luck !
I had the same problem, then I found a solution on this site.
Let me explain shortly;
Create your c++ project,
Have a look at project properties(⌘I),
Select Mach-O parser under binary properties,
Write your codes down,
Do not forget building your project (⌘B) before run.
You should change the settings for your project to build an executable instead of a dynamic library:
Invoking: MacOS X C++ Linker g++ -arch i386 -dynamiclib -o "libHelloWorld" ./main.o`
Go to project properties -> C/C++ Build -> Settings -> Build artifact, and select Executable in the first drop down list.
I am using Eclipse Oxygen and the following fixed my problem:
Right-click on your project and go to properties. Navigate to C/C++ Build > Tool Chain Editor and select MacOSX GCC in the Current toolchain, and Apply and Close.
Build your project with CMD+B and then run it.
I was having the same problem. The answer can be hard to find as the "binary not found" issue has cropped up several times before, with different causes and solutions (selecting the 64-bit parser, etc.).
It turns out that, in my case, the fix was simple: you have to do a manual build, just once, for every new project you create. After that, works as usual.
Details: using a fresh fresh install of Eclipse Indigo Service Release 1 on Mac OS 10.7.2.
If your project name contains a "." (dot), the binary file will not be generated on building project.
Remove all the "."(dots) from the project name and rebuilt it or try creating a new project.
Happy coding!
If you can successfully built but when try to run it getting error:
Possible solution could be adding new configuration with full path to your binary output file
(Run->Run Configuration...->Main->C++ Application):
I solved a similar problem with Eclipse by creating a "Launch Configuration". I am using the Indigo release of Eclipse on OSX Lion with CDT (C/C++ dev environment). I found the option to create a new launch configuration in Project->Properties->Run/Debug Settings.
I encountered this problem after creating and building an empty "Hello World Ansi C Autotools Project". The build process created a working executable as src/a.out. I could run a.out successfully from the terminal but Eclipse did not understand that this was an executable for my project until I created a launch configuration pointing to it. Once I did that I was able to run a.out as usual using the green run button.
I had the same problem, even when i had set the artifact to executable. It was because the shared lib setting was ticked and this causes a dylib to be made even though you have specified an executable.
I go this to run by setting the Builder Type to Internal Builder on the C/C++ Build tab, in the project properties dialog.
No matter which approach to take to solve this issue on your workspace, this problem seemed to have become native to the project that I had created. Neither using the arguments or making sure the gcc version for linking did not work. I did find an intuitive solution. Here it is:to the "...binary not available..." error.
Do the following:(remember the following steps are after you have taken either of the above routes and none of those have solved the issue.
1.) delete everything - the project and the files.
2.) create new project and source files
I had the similar issue but code was different. In File.h file make sure
virtual ~Destructor () {}; //Don't forget Curly braces {}
Above statement shows destructor initialized () and defined with curly braces { } . In my code I forgot to define Destructor.
Hope this helps
I was having the same problem, so I fiddled around a littpe bit and found out that if I clicked on the "profile" button (green play icon with a little clock under it), to the right of the "run" button, my program would Run the next time I clicked on the Run button.
I actually dont know what that did, but it allowed me to run the code.
if anybody knows why this helped, and whether it is an actual solution or not dont hesitate to relpy!
I was wondering whether it's possible to use Microsoft's C++ compiler and linker with NetBeans IDE?
If so, what's the best way of doing it.
P.S. I'm not interested in Mingw.
EDIT: Is it possible to get NetBeans to do error parsing (so that I can click on error and have NetBeans open the right file), intellisense, etc? I know NetBeans can work with g++ make files. Why not with nmake?
I am currently writing a plugin/toolchain to use Visual C++ on Netbeans.
You can find the project called VCC4N on source forge or on NetBeans plugins.
To be honest, I always do my spare time coding inside an ide (e.g. code::blocks, monodevelop, anjuta) or an editor (virtually always scite), and the compiling I do in a terminal via a makefile (handwritten, cmake, automake).
This isn't really a problem w.r.t. time to compile: F7 (or some other of the F keys) vs. (alt+tab, up, enter), where (alt+tab) and (up) are pressed nearly at the same time, but I get the great benefit of having up to full screen compiler reports, and often I am anyways testing my programs in a terminal. Also, it makes my code more independent of the IDE (ever tried to get a makefile from code::blocks for distribution purposes?).
The visual studio compiler is called cl.exe and the linker is link.exe. These are present in particular visual studio directories. From inside visual studio > project properties > C++ > Command Line, or by disabling "Suppress Banner" option there, you can find the command that visual studio runs. You can call these command lines from inside netbeans.
Getting all the file names into the list to compile may be more tricky. You need a build system for this. You can try to use the same mechanism that visual studio uses, but sorry my knowledge fails there. Alternatively, you can use CMake or some other build system. Then, whenever you add/delete a source file, you would have to update the CMakelist.txt to be able to compile.
You can get syntax highlighting, code graphing etc from netbeans without having a compiler installed I think (not certain, you may need cygwin or mingw for parsing). What you must do is create at least an empty makefile. If you want to use Microsoft's compiler then you either need to:
a) Write the makefile yourself to compile eveything using cl
b) Call on msdev from the makefile with the project name and it will compile everything
b) Call something like scons from the makefile to compile everything
I use netbeans to develop cross platform software, at this time though, I don't actually run the builds from netbeans.
