My setup includes: Windows Vista, Eclipse 3.5.0, and gdb, make, gcc 3.4.4, g++ 3.4.4 enabled through Cygwin, and environmental variable is already set.
My FIRST problem is that I can run and build an application like the information in Console:
**** Build of configuration Debug for project HelloWorld ****
make all <br />
Building file: ../src/HelloWorld.cpp <br />
Invoking: Cygwin C++ Compiler <br />
g++ -O0 -g3 -Wall -c -fmessage-length=0 -MMD -MP -MF"src/HelloWorld.d" <br /> -MT"src/HelloWorld.d" -o"src/HelloWorld.o" "../src/HelloWorld.cpp" <br />
Finished building: ../src/HelloWorld.cpp <br />
Building target: HelloWorld.exe <br />
Invoking: Cygwin C++ Linker <br />
g++ -o"HelloWorld.exe" ./src/HelloWorld.o <br />
Finished building target: HelloWorld.exe <br />
But in the Problems view, I still have the following warnings,
Error launching external scanner info generator (g++ -E -P -v -dD F:/workspace/.metadata/.plugins/org.eclipse.cdt.make.core/specs.cpp) <br />
Error launching external scanner info generator (g++ -E -P -v -dD F:/workspace/.metadata/.plugins/org.eclipse.cdt.make.core/specs.cpp) <br />
Error launching external scanner info generator (gcc -E -P -v -dD F:/workspace/.metadata/.plugins/org.eclipse.cdt.make.core/specs.c) <br />
Error launching external scanner info generator (gcc -E -P -v -dD F:/workspace/.metadata/.plugins/org.eclipse.cdt.make.core/specs.c)
My SECOND problem is that I have set up PATH but I cannot run 'g++ --version
' and 'gcc --version
' in the windows command, while 'make', 'gdb', 'gcc-3', and 'g++-3' work.
Does anyone know what I can do to fix those problems? Is the second problem related to the first problem?
Thanks

What is sure is your second problem could very well be related to your first issue:
From this thread:
Make sure gcc is installed and on the system PATH.
This other thread states the obvious:
a
PATH
env var change via the OS GUI won't take effect in an already running app (Eclipse), including an already open console window.
If you're re-launching Eclipse after the PATH change, you're not doing so from an existing console window, right?
Also, try copying thegcc.exe
executable toc:\WINNT
just as a test. It won't work from there stand-alone, but you should at least see some difference that will help you determine if your problem is indeed a PATH one.
For, cygwin environment, other hacks are possible:
Recent versions of Cygwin no longer have gcc.exe or g++.exe. These files have been replaced with .lnk files that point to gcc-3.exe and g++-3.exe (or whatever)
Some tools in Eclipse need to launch "gcc" or "g++" to generate some sort of info. The OS cannot find gcc.exe or g++.exe and so it returns an error.
I have found that the following procedure works for me:
1/ delete gcc.exe.lnk and g++.exe.lnk from cygwin/bin
2/ Copy gcc-3.exe to gcc.exe
3/ Copy g++-3.exe to g++.exe
Be aware though there:
