Eclipse can't find my MinGW toolchain for C/C++

I have a problem. Many have the same question but I didn't find the answer.

I installed gcc-4.9.0 on my PC but Eclipse won't find it. I used the default installation path:

C:\MinGW

A mismatch of 32 and 64 bit versions of eclipse and mingw can also contribute the gcc/g++ not-found problem. Make sure you stick to one version all the way from java, mingw, to eclipse.

As indicated in the above steps one thing I missed to do was saving user settings after adding the path variable. This suggested that the path for MinGW was not saved correctly.

Please check-in that aspect as well.

After updating the environment path variable, you must restart os.

This steps helped me when I faced the same problem:

First add the MinGW directory to your path system environment variable as in this link:

(https://www.youtube.com/watch?v=zLpaYVIoXqc)

After this when you want to create a project uncheck "Show project types and toolchains only if they are supported on the platorm" option. Choose MinGW GCC

Create your code but first build it with CTRL+B, after this mine worked perfectly.

I wish it will be helpful for other people who see this

  1. Setting PATH variable, add something like: "C:\Program Files (x86)\mingw-w64\i686-6.2.0-win32-dwarf-rt_v5-rev1\mingw32\bin"
  2. DO COPY gcc.exe to mingw32-gcc.exe in your path above

I also had this problem recently. I had some difficulty getting my Eclipse Luna SR2 4.4.2 running on Win 7 SP1 to see my newly-installed MinGW-w64 but I was able to resolve it by adding a MINGW_HOME environmental variable to my Win 7 installation, and then restarting Eclipse. (I didn't need to restart Windows.)

In my case, MinGW-w64 had installed itself at "C:Program Files\mingw-w64\x86_64-4.9.2-win32-seh-rt_v4_rev2" and so I needed to set MINGW_HOME to "C:Program Files\mingw-w64\x86_64-4.9.2-win32-seh-rt_v4_rev2\mingw64" so that it would point to the appropriate subdirectories (bin, etc, include, lib, ...).

In Win 7, environmental variables can be set via the "Environment Variables" button on the Control Panel -> System and Security -> System -> Advanced system settings. I added my MINGW_HOME variable to the "User variables" section.

I had this problem for a while and just now got it to work.
Here's what I did:
In Eclipse, go to Window>Preferences>C/C++>Build>Environment. Double click the row that has PATH in the leftmost column to open the list. Make sure you've got \bin at the end of your C:\MinGW in that list. Mine didn't have the \bin. I changed it to read C:\MinGW\bin and now it works like a charm.
Hope this helps.

Eclipse uses the system environment variable "PATH" to find a toolchain. So, in order to Eclipse could find MinGW toolchain, the path the to bin-directory of MinGW (e.g. "C:\MinGW\bin") should be specified in the "PATH" environment variable.

P.S. And don't forget to re-launch Eclipse after modifying the environment variable :)
