I am trying to compile a project, but CMake stops right at the beginning with the message that gcc is broken (see below). I am ignoramus when it comes to CMake, so any help where to get me starting debugging this problem is very very welcome.
- GCC (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3 (I checked that my GCC compiles a 'hello world' problem)
- CMake version 2.8.7
- CMake command:
cmake -G "Unix Makefiles" -DCMAKE_BUILD_TYPE=Debug ../Mantid
Output to terminal:
-- The C compiler identification is GNU
-- The CXX compiler identification is GNU
-- Could not determine Eclipse version, assuming at least 3.6 (Helios). Adjust CMAKE_ECLIPSE_VERSION if this is wrong.
-- Check for working C compiler: /usr/bin/gcc-4.6
-- Check for working C compiler: /usr/bin/gcc-4.6 -- broken
CMake Error at /usr/share/cmake-2.8/Modules/CMakeTestCCompiler.cmake:52 (MESSAGE):
The C compiler "/usr/bin/gcc-4.6" is not able to compile a simple testprogram.
It fails with the following output:
