I have upgraded my toolchain from GNU Tools ARM Embedded 4.9.3 to GNU Tools ARM Embedded 5.2.4. I edited the PATH in Eclipse to first list the GNU toolchain and then Cygwin. I am still getting the following errors:
Program "gcc" not found in PATH
Program "g++" not found in PATH
Eclipse says these errors are a "C/C++ Scanner Discovery Problem" and points me to the location "Project Properties, C++ Preprocessor Include/Providers, [CDT GCC Built-in Compiler Settings] options".
This is the same error that I had before with the 4.9.3 toolchain in Eclipse. For some reason when I try to compile in the Cygwin terminal, I get the other error of not recognizing cortex-m7.
