Still get nothing to build error [message #755841]

I am getting this error when im trying to run a project.I added the C:\mingw\bin to my path variable and here is my path variable C:\Program Files (x86)\MiKTeX 2.9\miktex\bin;%CommonProgramFiles%\Microsoft Shared\Windows Live;C:\Program Files (x86)\NVIDIA Corporation\PhysX\Common;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\FPC\2.4.4\bin\i386-Win32;C:\MinGW\bin;

After I build the project " nothing to build for x " is printed on console and suddenly it disappears resulting with a blank screen instead of an output. Only time I got the output properly is that I manually add a path variable(C:\mingw\bin ) in run configurations but I don't want to make this for every different file. Please help.

##I am using windows 7 64 bit by the way.

If it built once, then you may still have .obj's and an .exe
Try using the clean option to delete them and rebuild.

I see the same problem with MinGW.

For Visual C the problem is worse, I get no obj and no exe
and it tells me it has nothing to build any way.

But I can get visual C to build using an existing make file or
using a batch file that executes the build steps.

So far I have been quite frustrated as there seems no
easy way to get any information on why it does not see anything to build.
Or detail of the path it takes internally.

Cheers,
Jerry

I have exactly the same problem. I am making my first attempt to run a program under Eclipse. I am using C++ under Windows XP with the MinGW toolchain. I precisely followed the tutorial instructions for creating the "HelloWorld" program. When I attempt to run, I get the error "Nothing to build for HelloWorld".

The executable gets created. I have tried running it directly (outside the Eclipse debugger), and I get the message: "libgcc_s_dw2-1.dll was not found". Since that file is on mingw\bin, I suspect there may be a problem with my path.

There are still some things I can try. But I think the best option may be to use a different SDK.

I had the same problem. I finally resolved everything by carefully following the directions for installing MinGW which require that you install the C and C++ compilers and MSYS basic system, and MinGW developer toolk packages. Also make sure that C:\MinGW\bin;C:\MinGW\msys\1.0\bin are added to your Path system variables. Insuring all of these did the trick for me.

I had this problem and must have searched every thread for a solution. In the end my problem was with the compiler installation minGW . When installing this ensure that your virus protection is turned off as this can prevent some of the dll files from being downloaded and will not flag up an error.
After installing the compiler without the virus protection, reinstall eclipse and it should work. I had tried everything else before that and nothing worked.
But now thankfully it has . Good luck

You are probably missing DOING "Refresh" after "Build".
Right click on project and "Refresh" or just "press F5" after building the project.
You need to do this just once
