Hi guys,
I'm trying to cross-compile a project using CMake and gdc (or
better: the gdmd port). My CMakeLists-file is the following:
cmake_minimum_required(VERSION 2.8.1)
set(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH}
"${CMAKE_SOURCE_DIR}/cmake-d")
SET(CMAKE_SYSTEM_NAME Linux)
project(myapp D)
set(CMAKE_D_FLAGS "${CMAKE_D_FLAGS} ${GLOBAL_DMD_DEFS}")
set(SOURCES
main.d
generic.d
)
include_directories(.)
add_executable(myapp ${SOURCES})
I'm working on Windows and I want compile the project for the
target linux system. So, I downloaded the gdc (x86_64-linux-gnu),
extracted it and set the PATH variable. Unfortunately, when I
configure my project using CMake, I'm getting the following
message:
CMake Error at
C:/Users/User/Desktop/Project/cmake-d/CMakeDetermineDCompiler.cmake:32 (MESSAGE):
Could not find compiler set in environment variable C:
CMAKE_D_COMPILER-NOTFOUND.
Call Stack (most recent call first):
CMakeLists.txt:6 (project)
CMake Error: CMAKE_D_COMPILER not set, after EnableLanguage
I think CMake cannot find the compiler because the executables of
gdc are named like "x86_64-unknown-linux-gnu-gdc". So, I've added
the following to my CMakeLists-file:
set(CMAKE_D_COMPILER x86_64-unknown-linux-gnu-gdmd)
But this also fails with the following error:
The D compiler identification is GNU

To force a specific D compiler set the DC environment variable
ie - export DC="/usr/bin/dmd"

is not able to compile a simple test program.
It fails with the following output:

Does anyone know what can cause the problem here? I've also set
the DC environment variable but I'm still getting the errors :(
