Summary: __cpack_system_name incorrectly set when compiling
with Mingw-w64
Description:
I have a CMake/CPack project that I am cross-compiling for 32 and 64-bit
Windows. CPack generates an NSIS installer for both architectures but
incorrectly detects a 32-bit compiler in both cases.
After looking through the source code for Modules/CPack.cmake, I came across the
following:
if(${__cpack_system_name} MATCHES Windows)
if(CMAKE_CL_64)
set(__cpack_system_name win64)
...
It appears that CPack is only checking for the 64-bit compiler that ships with
MSVC++ and not for Mingw-w64.
Steps to Reproduce:
Assuming you have the Mingw-w64 compiler installed, the following steps will
reproduce the problem:
1. Create a very simple project that consists of the following files:
test.cpp:
#include <iostream>
int main(int argc, char ** argv)
{
std::cout << "Hello world!" << std::endl;
return 0;
}
CMakeLists.txt:
cmake_minimum_required(VERSION 2.8)
project(test)
add_executable(test test.cpp)
install(TARGETS test RUNTIME DESTINATION bin)
include(CPack)
2. Create a CMake toolchain file like so (toolchain.cmake in the same
directory):
set(CMAKE_SYSTEM_NAME Windows)
set(CMAKE_C_COMPILER x86_64-w64-mingw32-gcc)
set(CMAKE_CXX_COMPILER x86_64-w64-mingw32-g++)
set(CMAKE_RC_COMPILER x86_64-w64-mingw32-windres)
set(CMAKE_FIND_ROOT_PATH /usr/x86_64-w64-mingw32)
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)
(You may need to adjust the value of "CMAKE_FIND_ROOT_PATH".)
3. Build the package:
mkdir build ; cd build
cmake -DCMAKE_TOOLCHAIN_FILE=../toolchain.cmake ..
make package
4. You should end up with an incorrectly named installer titled:
test-0.1.1-win32.exe
