I had the same problem  Eclipse couldn t find  g    and  gcc  in PATH even they were accessible from command-line  I was also sure they are pointed by PATH correctly    I have just deleted the   metadata  folder from Eclipse s Workspace as a mean to reset it and this worked for me

The PATH is locate at Project Properties   C C   Build   Environment  see screenshot below       For your reference  I am using MinGW  I got the same error before I got the MSYS install  Later I found out that I also need MSYS to be install because the make exe wasn t come with MinGW   I don t this error was cause be MSYS    After MSYS is installed  add MSYS and MinGW path into environment variable  restart Eclipse  Remember to rebuild your project in order to rectify the error  If error still persist after restart  recreate the workspace  At least this has solved the problem on my site  hopes this help on you too   Good luck

enter image description hereIf you just want to run C program but meet this error  it might mean that MinGw c   compiler has not been installed even if  C  MinGW bin  has already been added to Windows Path variable   Solution    Run  mingw-get-setup exe  to open MinGW Installation Manager Open All Packages- MinGw- MinGW Base System- MinGW Compiler Suite Select the following compilers to install     mingw32-gcc-g      mingw32-gcc-v3-core    mingw32-gcc-vc-g   Click Installation- Apply Changes to apply the above changes Wait for the installation finishing There might be some errors  just ignore them   Restart Eclipse  Done    It Worked in my environment    Hope it works in your case

i think cgywin might not work for you as you can only compile your code in Win7 if you fire up the command prompt  you need to use MinGW compiler toolset instead  After you have install your compiler  go to Properties- C C   Build- Tool Chain Editor -  Change your current toolchain to MinGW GCC

WINDOWS 7  If there is anyone new reading this  make sure to simply try a clean install of mingw before any of this  It will save you sooooo much time if that is your problem   I opened up wingw installer  selected every program for removal  apply changes  under installation tab  upper left corner   closed out  went back in and installed every file  in  Basic Setup  section  availible  after that eclipse worked fine using  MinGW GCC  toolchain when starting a new C   project   I hope this works for someone else  If not  I would do a reinstall of JDK  Java Developer s Kit  and ECLIPSE as well  I have a 64bit system but I could only get the 32bit versions of Eclipse and JDK to work together

First Install MinGW or other C C   compiler as it s required by Eclipse C     Use https   sourceforge net projects mingw-w64  as unbelievably the download cnet com s version has malware attached    Back to Eclipse   Now in all those path settings that the Eclipse Help manual talks about INSTEAD of typing the path  Select Variables and     MINGW HOME      and do so for all instances which would ask for the compiler s path     First would be to click Preferences of the whatever project and C C   General then Paths and Symbols and add the     MINGW HOME   to those paths of for the compiler    Next simply add the home directory to the Build Variables under the C   C Build  Build Variables Screen Capture

This is how I got rid of it    Install the MinGW  Select all files in the Basic Setup and select apply the changes  Select new C   Project You will be able to see  MinGW GCC  in the toolchain section select the same and create project

All the tips did not work for me using the Gaisler Tools for GR712RC Installation for OS RTEMS  I m using the Eclipse Kepler   The simple way was making a copy of sparc-rtems-gcc exe to gcc exe  and sparc-rtems-g   exe to g   exe  in the C  opt rtems-4 10-mingw bin directory

I had a similar problem  The error is raised  but the code is compiled and linked  The error was caused by the Error Parser using a different configuration than the one that is compiled    The error parser configuration was only valid for the Linux configuration of my software  My active configuration was set for MinGW and Windows    Solution    In Elipse under Windows- Preferences- C C  - Indexer set Build Configuration for the indexer to Use active build configuration  Clean and rebuild  otherwise the old errors will remain visible

I got the same problem with mingw-64  x86 64-4 9 1-release-posix-seh-rt v3-rev1   Eclipse Luna 4 4 1 and CDT 8 5 0 201409172108  using Windows 7   I solved this problem by putting the following two environment variables under     Window -  Preferences -  C C   -  Build-  Environment    name  MINGW HOME value   mingw installation directory without   bin   name  MSYS HOME value   msys installation directory without   bin     You can check      Window -  Preferences -  C C   -  Build -  Settings -  Discovery -  CDT GCC   Built-in Compiler Settings MinGW   Shared       if it doesn t complain  Toolchain MinGW GCC is not detected on this system  then you re all set

The reason is that eclipse cannot find your gcc or g   environment variable path   You might have tried to run c or c   or fortran but eclipse cannot find out the compiler    So  add the path in your environment variable    Windows -  Search -environment variables -  click on environmental variables at bottom  Click on path - edit -  new -  your variable path   Path should be entire  for example    C  Users mahidhai cygwin64 usr sbin   Make sure that the variable is permanently stored  It is not erased after you close the environment variables GUI   Sometimes you might find it difficult to add a path variable  Make sure windows is updated   Even if Windows is updated and you have problems  directly go to the registry and navigate to the below   HKLM SYSTEM CurrentControlSet Control Session Manager Environment   Add your path here  Remove any unnecessary repetitions of path variables   Note  You need to add your path variables in system environment variables -path

Had this problem on windows 10  eclipse Neon Release  4 6 0  and MSYS2 installed  Eclipse kept complaining that  Program  g    not found in PATH    and  Program  gcc  not found in PATH     yet it was compiling and running my C   code  From the command prompt  I could run g     Solution was to define the C   Environmental variable for eclipse called  PATH  to point to windows variable called  path  also   Path   Menus  Preferences  C C    Build  Environment  Looks like eclipse is case sensitive with the name of this environmental  while windows doesn t care about the case

You need a gcc  g   compiler toolchain  on your windows machine  for the eclipse which you have manually downloaded  One of the options can be done implicit via cygwin installation by selecting proper development packages for gcc  g    and then add the location of the compiled gcc  g   package like C  cygwin etc alternatives to the PATH variable for windows environment   After this open eclipse and go to Project- gt properties- gt C C   Tool Chain Editor and add replace default GNU C   compiler and GNU C Compiler with Cygwin C   compiler and Cygwin C compiler and rebuild the project  The errors related to gcc  g   PATH not found will now be gone

For me it got fixed with   Go to  Window -  Preferences -  C C   -  Build -  Environment  Then press  Add      Name  MINGW HOME  Value  C  MinGW  yours might be different if you choose a custom path   Hit  Apply and Close   Now  it shoud work if you did everything correctly

Maybe it has nothing to do here  but it could be useful for someone  I installed jdk on  D  Program Files Java jdk1 7 0 06 bin So I added it to  PATH  variable and checked it on cmd and everything was ok  but Eclipse kept showing me that error  I used quotation marks on  PATH  so it reads something like    SYSTEMROOT  System32  D  Program Files Java jdk1 7 0 06 bin    and problem solved

I had the same problem  the only solution that worked for me was this    Open command-line and check whether  g    actually executes the compiler If  1  works  uncheck Project- Build automatically in Eclipse Clean project Build project

I had similar problem and I solved it by   Installing g   The GNU C   compiler using Ubuntu Software Center  Changing in  Window -  Preferences -  C C   -  Build -  Settings -  Discovery -  CDT GCC Build in Complier Settings  Shared  from    COMMAND  -E -P -v -dD    INPUTS   to   usr bin   COMMAND  -E -P -v -dD    INPUTS    I hope it helps

If you have your PATH setup and you can see g   --version via the command line  then try to delete the project and create a new c   project    So the reset defaults might work but I think it has to update the PATH if it wasn t added before

User · Answer

You need   C  cygnus cygwin-b20 H-i586-cygwin32 bin   in the PATH   and not  C  cygnus cygwin-b20 H-i586-cygwin32 bin g     as you wrote
