On my MacBook Air I need to use Eclipse to make some c++ programs for school. So I downloaded Eclipse for C++ from the eclipse.org and made a little Hello World program. However, when I try to run the program, it just gives me the error "Launch failed. Binary not found".
When I try to build the program, this is the output:
**** Build of configuration Debug for project HelloWorldC ****
make all
Cannot run program "make": Unknown reason
Error: Program "make" is not found in PATH
PATH=[/usr/bin:/bin:/usr/sbin:/sbin]
**** Build Finished ****
However, I tried to make a hello world application in Xcode and that works perfect...
Unfortunately, I cannot use Xcode because the teacher is only allowing Eclipse projects...
I found the solution.
The problem is that you can install the latest Xcode (4.3) only from the app store, and by default it seems like the c++ compiler is only accessible through Xcode, to solve this you need to:
Open Xcode
Go to Preferences
Go to Downloads
Install Command Line Tools
Make sure the "UNIX Development Tools" are installed with the Xcode installer.
I don't have Eclipse here, but on my Mac book which make gives me:
correa$ which make
/usr/bin/make
which is one of the paths it's looking for.
If I remember correctly, it was installed simply installing Xcode from the app store. You should try to check if make is really installed in your system, if not, you could try reinstalling xcode to see if it fixes the problem.
Hope this little bit can give you a starting point. Can't yet comment on the question, otherwise would have just made a comment.

I have never used qt before, but I got a task to build an already existing application for Windows and Mac using the newest version of qt. What I have done so far is:
Installed Visual Studio Professional 2017.
Installed the latest Qt 5 Open Source.
Note: when installing the QT 5 I installed all of the components under QT/ QT 5.10.1 which were: qt 5.10.1 components and under QT/Tools I installed QT Creator 4.6.0 CDB Debugger Support and MinGW 5.3.0 : qt 5 Tools
I cloned the branch from GitHub that I wanted to build to C:/Projects
Then in Git Bash I cd to the project and tried to run qmake. The first time I had this problem:
"bash: qmake: command not found"
After searching into the problem I found out that I haven't added "Qt/5.10.1/msvc2017_64/bin" to PATH and I added it. Now when I echo $PATH I can see the directory added.
Now after bash recognises qmake and I try to run it it says:
Project ERROR: Cannot run target compiler 'cl'. Output:
===================
Maybe you forgot to setup the environment?
I have no idea how to fix the problem due to the fact that I have never used QT to build anything before. Can you help me?
In the read me file for the application I am trying to build it says:
Step-by-step instructions
1. Clone this branch
2. cd into the project
3. Run qmake - this wil generate Makefiles for all of the project's modules
4.Run make (Use the -j4 of -j flags - this greatly speeds up the build process - see the manual page for make for more info). You can also use the -s flag to silence the output - this also wins you a few seconds.
I am a bit puzzled by the instructions, it does not say to run qmake -project anywhere, but there is a qt project file in the directory that I cd to. Does this mean that I don't have to run qmake -project?
Also I have no idea how to run make by using the -j4 and -j flags and how to run flags in general. Could someone help me?
I believe that for the Cannot Run Compiler 'cl' issue I have some kind of a problem with the set up. Did I install too many components or is it to do with the VS setup?
I highly recommend you to install Qt from the Qt installer, and to use Qt Creator.
However, if you want to use it from source, you first need to get a compiler (ex: MinGW). Then you need to execute the instructions, but you need to use a MinGW (or whatever compiler you use) command prompt, which will automatically set the environment variables needed.
Note that this is Windows specific. On mac and linux, the compiler's environment variables are already set in the default command prompt (if there is a compiler, obviously).
I am currently trying to set my eclipse so that I can start c++ development on my Windows computer. However, I am stuck with some errors. But first, here is what I did so far:
Installed the CDT for Eclipse
Installed Cygwin (with the additional packages gcc, gcc and make)
Added all "paths for headers" in Eclipse
The problem is that when I try to run my Hello World program, I get Launch failed. Binary not found.
I already build and rebuild the project but the program is still not running. It must be because of these errors that I have:
/bin/sh: g++: command not found
make: ***[src/HelloWorld.o] Error 127
What can I do to solve these errors?
Try running the Cygwin setup.exe again and select the packages for g++. Search for that and make sure those are installed. It should be under the name gcc-g++. The C++ compiler is installed separately from the C compiler.
Ok, I figured it out by myself. Since this really freaked me out, I want anyone else who has this problem to know how I solved it.
So apparently, since I had g++, gcc and all that installed, it had to be a problem with the path.
So what I did was check my path. If you don't know how to edit it, check this link http://www.computerhope.com/issues/ch000549.htm
So in there, I chose Path under the System variables and clicked on Edit.... What I noticed was that instead of C:\cygwin64 it said C:\cygwin. All I did was append the 64 (since I had installed the 64-bit version of cygwin) and I was done.
I restarted Eclipse, cleaned and built the project and the errors where gone!
I have installed Code::Blocks on Ubuntu Linux 12.10 and trying to use examples of Openframeworks. The HelloWorld and other programs that I write in Code::Blocks build and run fine.
However, when I open Code::Blocks workspace of an empty example of OpenFrameworks in Code::Blocks and try to build it, I get an error saying No rule to make target ../../../libspoco/lib/linux64/libPocoNet.a needed by bin/emptyExample_debug
I checked in the relative path and there's no folder named linux64, but there's only a folder named linux and perhaps that's why I am getting this error while trying to build. My question is how do change this rule? This linux64 problem might also be there in other projects, is there a universal place where this can be changed to 'linux' instead of 'linux64'
check your machine and codeblocks whether both are of same bit . one of the easiest way to avoid this conflict is install codeblocks from ubuntu software center .
I've spent hours looking up how to fix this problem but nothing has worked. I have eclipse Indigo with CDT and ive downloaded cygwin and packages such as g++, make file, etc. When I try to execute any code I end up with the error Launch failed. Binary not found. I've also set the system path C:\cygwin\bin. How can I set up eclipse so I can use it as my IDE for c++?
Found the problem, I didn't press the hammer button to build the project first. I've only used eclipse for java and I could just hit run and everything would work fine.
Try downloading MinGW, and using those compilers. The Cygwin tools require libraries that Eclipse may not load. The MinGW executables do not require any additional environment like Cygwin does.
Also, in order to use most Cygwin executables, you need to launch the Cygwin environment first.
I am trying to use Eclipse CDT with Cygwin, but I have problems with the debugger. I have done the following:
- installed Eclipse CDT
- installed Cygwin with gcc, g++ make and gdb
- added c:\cygwin\bin to PATH
- created a new Hello World application in Eclipse
Compiling went well from Eclipse. The first problem was that I had to set the executable manually in the run configuration. Having done this, I running also worked. But when I try to debug, I get the following error:
When I switch to debug perspective, I can see the following:
I tried different debug configurations, but I always get the same result.
First, make sure gdb is located on c:\cygwin\bin. I believe executing which gdb on cygwin might help you do that.
Now, instead of adding this information to PATH and making it available to all your Windows applications, try adding it to your project settings inside Eclipse, like this guy did:
