Whenever I compile a source code in code::blocks, I encounter an error which tells me this:
Build file: "no target" in "no project" (compiler: unknown)
Below is a link showing the image of a code where I am encountering this issue
compilation problem
THE COMPILER I AM USING IS THE GNU GCC COMPILER.
How do I solve this issue?
For the above code I hadn't created a project.
But when I do create a project I encounter this message:
debug in train (compiler: GNU GCC COMPILER)
I am also attaching an image of the code showing this message
compilation problem
here are the contents of the build log tab
build log tab
Search for the file "guimain.exe" and run.
It should be in the "libexec \ mingw-get \ guimain.exe" directory
Choose to include the "mingw32-gcc-g ++ - bin" package and install this, it will work.
I had the same problem and found that this g ++ does not install installed via mingw.

You could change some of the project settings but I think It'd be easier if you start from the beginning.
Run code blocks and then click create new project -> console application and choose the name and the path of it.
It seems like you've just created the cpp file and opened it in code blocks.
Correct me if I'm wrong.
Make sure your Settings -> Compiler -> Toolchain executables shows the right compiler. Clicking on auto-detect seems to work.
Then create a new project of type Console App (as suggested already). After the project is created, go to the left menu and click on your project, go to Source, and open main.And then delete the "Hello World" code already there and copy/paste in your source.
I did these steps and then Build and Run worked just fine.

I have searched all over the web and have tried everything I could to fix this problem, to no avail. So here I am making a new post, hoping to fix this terribly frustrating problem.
I have the Eclipse IDE for C/C++ Developers that on my Windows 7 computer. The version of Eclipse is Luna Service Release 2 (4.4.2) and the build ID is 20150219-0600.
I have MinGW installed onto my computer, and I downloaded all the package choices just to be safe.
I create a C++ project. The "Project type" is Executable > Empty Project and the "Toolchains" is "Cross GCC".
I select both "Debug" and "Release" in the "Configurations".
I leave the "Cross compiler prefix" blank because I don't know what to write. I then put in "F:\MinGW" as the "Cross compiler path".
I create a new source file in the project and write the infamous Hello World program (in C++, of course). When I save the project, it gives me two errors in the "Problems" tab:
Program "g++" not found in PATH
Program "gcc" not found in PATH
When I build the project, it adds on another error:
Program "make" not found in PATH
I go to Project > Properties > C/C++ Build > Tool Chain Editor and change the "Current builder" from "Gnu Make Builder" to "CDT Internal Builder".
The error Program "make" not found in PATH then disappears.
I go to Window > Preferences > C/C++ > New C/C++ Project Wizard > Makefile Project and set the "Binary parser" to "PE Windows Parser". I clear the project, save the project, and build the project, but the 2 errors remain.
If I go to Project > Properties > C/C++ Build > Environment and set the value of the "PATH" variable to "F:\MinGW\bin", still nothing happens and the two errors remain.
Now, when I attempt to run the project (ctrl + F11), it spits out the error Launch Failed. Binary not found.
In the "Project Explorer", I see a HelloWorld file that contains an "Includes" file (containing the compiler libraries?), a "Debug" folder (containing a HelloWorld.exe and a main.o), and a main.cpp file (containing my Hello World program).
Thank you in advance for taking the time to read this and for trying to help.
You need to update environment variable PATH. Check this page.
You must add C:\MinGW\bin; to your user PATH environment variable manually.
I suggest, not a solution, at least you want to make sure the following.
Recheck that the PATH is set up right. Sometime we think we did, but the computer does not. In the command line, type the following command to see the gcc installed right and PATH is set right.
gcc --version
echo $PATH
or
echo %PATH%
All things are right as you did above, but it does not work?, Then remove and reinstall mingw and eclipse CDT cleanly. Don't change and keep the default options in the Eclipse CDT. Without any option changes CDT, it should work NOWADAYS. Eclipse CDT(8.7, 8.8) is pretty much stable.
Blessings,

I did look up on the Internet to find the solution for my problems, unfortunately all advices didn't seem to help so perhaps you will be more helpful in my case.
I did set up my Eclipse IDE with MinGW,
I did set up my Windows' environment variables right, for example:
added C:\Program Files\eclipse; C:\MinGW\bin;C:\MinGW\msys\1.0\bin
and somehow managed to create project with .cpp file that actually worked, at the beggining I build this file and than run it with these simple icons. Somehow, it compiled without errors and output the right results.
I hoped that it would remain perfect for eternity, but somehow today while dealing with new c++ project I have encountered the following problems.
I build new C++ project, by clicking:
File -> New -> C++ Project -> marking executable project Hello World Project -> by default I set up to use MinGW toolchain (nothing has changed since the moment it worked perfectly smooth) -> name project and start work.
Building project looks ok, I get no errors whatsover. But when I try to run it the console window is completely blank - with popping info: Nothing to build for [project name].
I really hope that once I've made some project actually work all changes will remain untouched and that I will not have to fiddle around once again with all these settings.
I did not change anything at all and now it doesn't work...
Right click on project -> Properties -> C/C++ Build -> Environment -> all variables are set.
Toolchain set to MinGW which has worked so well.
And yet I can't run this executable program, this IDE is really starting to drive me crazy.
Any idea what might have happened over the last magical six hours when suddenly Eclipse refuse to work properly again ?
Try to right click the eclipse project and click refresh. An item should appear under executables. If an item appears you should be able to run it from inside eclipse (not sure how though, maybe by double clicking or from the right click menu) or by using the command promt. To run it through the command prompt, using cd command browse to the folder where the executable file resides (somewhere inside the project folder inside your workspace folder) and run it by typing the name of the executable (fx hello.exe or just hello).
I'm trying to use the cpu of bochs in my graduate course project. I want to create a project of it in eclipse so I can modify it and compile it and also see the errors ...
I have the source code and I use visual studio's nmake to build, compile it. but the problem is that it doesn't report me the errors and the only way to know the error happens or not is to wait until nmake ends and see if the .exe file is created or not. after that the process of finding errors is a bad headache.
so I'm trying to use ubuntu OS and use eclipse. anyone knows how to create a project for bochs in this?
Also the more important thing is a tutorial that I can learn bochs cpu codes. because the official site's tutorial has no use.
haha,
I found it myself.
just go to bochs official site and download the source code for linux.
extract the zip file somewhere.
open a terminal and go to the extracted folder.
type:
./configure
this will check your system and set the values for the #define arguments in a file called makefile.
now open eclipse.(I assume that you have the c/c++ CDT). FILE>NEW PROJECT
In the opened dialogue open c/c++ tree, and select "Makefile project with existing code" and click next. next put a name for your project and in the "existing code location" browse the extracted folder. next select CROSS GCC as toolchain. then click finish.
there you go. now build the project and it should work.
remember that for running project you must give bochs command line arguments which is available in eclipse and you can find out how with a search in forums.
I am trying to write, compile and execute a "HelloWorld" C++ program using Eclipse. I have managed to install and run Eclipse, create a new project and write the HelloWorld program. Now I would like to compile it and to run.
I did not find "Compile" option in Eclipse, but I found "Build Project" option in the "Project" menu. I assume that Build is what I call "compilation". After I clicked this options, Eclipse generated "Debug" folder, containing "src" sub-folder as well as 3 files: "sources.mk", "objects.mk" and "makefile". First, I do not know what these files mean (and which of them is my "executable"). Second, I still need to execute my program. I tried to click "Run" option in the "Run" menu. As a result I got an error message: "Launch failed. Binary not found".
Can anybody, please, help me to compile and run my code using Eclipse.
Eclipse being an IDE is meant to create projects not restricted to just one file as a result multiple files exists which have to be linked and compiled so as to work in sync as per the methods implemented in the project.To run the project or a particular program a binary of that particular project is required which gets created only if the build is successful .So a successful build is must for binary creation which in turn is responsible for running the project or program.
So first build the project using Ctrl+B after succesfull build then run the project.
This simple question was asked nine years ago, so I don't know if it is still active. Anyway, one thing not mentioned in the responses so far that might be helpful to others is that Eclipse requires a "Run Configuration" to run programs. From the original post, if the "Build Project" command returned successfully, then the "Debug" folder should also contain a file called "HelloWorld" at the same folder level as "makefile" and "objects.mk". That is your executable. To run it, go to Run -> Run Configurations, which should produce a popup containing a field called "C/C++ Application". Click the "Browse" button, find, and select the "HelloWorld" executable in the "Debug" folder. Click "Run" in the lower right and you should see your output.
I'm trying to use Eclipse CDT (Version: Indigo Service Release 1 Build id: 20110916-0149) to build and debug my c/c++ project in RHEL6 64 bit Linux, and I'm having issues. I've done what I thought was necessary to use an alternate toolchain to perform the compilation, but something seems to be missing, as eclipse says that it compiled the source, but it didn't really do it.
For the setup I went to C/C++ Project Properties -> C/C++ Build configuring the "Debug" configuration, on the "Builder Settings" tab I unchecked the "Use default build command" checkbox, and entered the name of my toolchain "mk all" into the "Build command" field. I then unchecked the "Generate Makefiles automatically" checkbox. Next I changed the "Build Directory" field to be "". Lastly I went to the "Behavior" tab and unchecked the "Build on resource save (Auto build)" checkbox and changed the "make build target" to be "all ${selected_resource_loc}" .
Now, when I go to my project, and select a subdirectory that needs to be built, and then click on the build button on the toolbar this is what happens:
1) I see the "Build Project..." in the progress window briefly
2) The CDT build console displays this:
**** Build of configuration Debug for project myproj ****
mk all
**** Build Finished ****
The above is what I see when my code needs rebuilt, does not need rebuilt, and when there are errors in the compilation. I can verify this by opening a bash terminal and typing "mk" in the directory I want to build. When I compile from the terminal, I can see the compiler output (success and errors etc..), but eclipse shows me nothing of the sorts.
I must be missing something, but I'm not sure what. Does anyone have any ideas of what I'm doing wrong?
--update--
I found out what part of my issue was, which turned out to be that my build tool was invoked via a bash script without a shebang at the top.
My next issue is that the build is always invoked from the root of the project, which has no makefile. I have tried putting the "${selected_resource_loc}" variable into both the "make build target" field, but it does not seem to have the correct effect as my "mk all" command seems to be invoked with the variable being translated to an empty string every time. Any ideas on this side issue?
'DEAR PEOPLE FROM THE FUTURE: Here's what we've figured out so far ...'
I sorta solved my issue. I had asked a friend with a similar setup to try this out, and he got it to work on the first try. I then concluded that it was either my install or my project. Thus, I proceeded to delete the project files (.project and .cproject) and recreate the project. After I completed that, it seemed to work like a charm. I must have selected an obscure incompatible project option, that caused something to not expand the ${selected_resource_loc} variable. Weird. I hope this helps someone along the way.
