Summary: CMAKE_C_COMPILER_VERSION is wrong due to a bug in
gcc
Description:
I suppose CMAKE_C_COMPILER_VERSION and CMAKE_CXX_COMPILER_VERSION are obtained
from the maccros __GNUC__, __GNUC_MINOR__ and __GNUC_PATCHLEVEL__. It seems that
gcc 4.5.1 has a bug : __GNUC_PATCHLEVEL__ is set to 0 instead of 1. It implies
that CMake is wrong when loading the compiler information from gcc 4.5.1. Maybe
the version should be checked with the maccro __VERSION__, or obtained directly
from the command "gcc --version".
Steps to Reproduce:
Simply create a project compiled with gcc 4.5.1 using C or CXX.
The bug of gcc can be observed with the following C++ code :
#include <iostream>
int main(int argc, char** argv)
{
std::cout << __GNUC__ << "." << __GNUC_MINOR__ << "." << __GNUC_PATCHLEVEL__
<< std::endl;
return 0;
}
Additional Information:
Note that gcc 4.5.1 is the default compiler on openSUSE 11.4.
