problem with g++ and CXX in Cmake

[crwatts]

I am trying to compile a pice of software using Cmake and get the following error. I have checked using yum to make sure that gcc. gcc-c++ and ncurses are all installed and up to date. Any ideas?

-- The C compiler identification is GNU 4.4.7
-- The CXX compiler identification is unknown
-- Check for working C compiler: /usr/lib64/ccache/gcc
-- Check for working C compiler: /usr/lib64/ccache/gcc -- works
-- Detecting C compiler ABI info
-- Detecting C compiler ABI info - done
CMake Error at CMakeLists.txt:5 (project):
The CMAKE_CXX_COMPILER:

g++44

is not a full path and was not found in the PATH.

Tell CMake where to find the compiler by setting either the environment
variable "CXX" or the CMake cache entry CMAKE_CXX_COMPILER to the full path
to the compiler, or to the compiler name if it is in the PATH.

sorry, one other pievce of info. This is the bootstrap shell.

Code: Select all

if [ $(uname) == 'Linux' ]
then
if [ -e /etc/gentoo-release ]
then
	export LDFLAGS="-nopie"
elif [ -e /etc/redhat-release ]
then
	CMAKE_DEFS="-DCMAKE_CXX_COMPILER=g++44"
fi
elif [ $(uname) == 'Darwin' ]
then
	# sudo ports install gcc44
	CMAKE_DEFS="-DCMAKE_CXX_COMPILER=/opt/local/bin/g++-mp-4.4"
fi
CMAKE_DEFS="-DCMAKE_INSTALL_PREFIX=${PWD} $CMAKE_DEFS"
if [ $# == 1 ]
then
	case $1 in
	'debug')
		CMAKE_DEFS="-DCMAKE_BUILD_TYPE=Debug $CMAKE_DEFS"
		;;
	'release')
		CMAKE_DEFS="-DCMAKE_BUILD_TYPE=Release $CMAKE_DEFS"
		;;
	'static')
		CMAKE_DEFS="-DCMAKE_BUILD_TYPE=Release -DCMAKE_EXE_LINKER_FLAGS=-static $CMAKE_DEFS"
		;;	
	esac
fi

rm -rf build

mkdir build

cd build && cmake .. ${CMAKE_DEFS}

The g++ compiler on CentOS 6 is just called g++ not g++44. Your script is setting the wrong value, it seems to think it's on CentOS 5 where the default compiler is 4.1.2 and the 4.4.7 compiler is an optional parallel install called g++44.

problem solved, there is an error in the bootstrap file.
