How to cross-compile FastDDS from Linux to windows. [13667]

[ilikecola]

I am using x86_64-w64-mingw32-gcc-posix to try cross-compiling FastDDS from ubuntu to windows.
but TimedMutex.hpp cannot be compiled.

Here is my compiler

Using built-in specs.
COLLECT_GCC=x86_64-w64-mingw32-gcc
COLLECT_LTO_WRAPPER=/usr/lib/gcc/x86_64-w64-mingw32/9.3-posix/lto-wrapper

Here is my crosscompile cmake file.

# set the name of the target system
set(CMAKE_SYSTEM_NAME "Windows" CACHE STRING "Target system")
set(CMAKE_SYSTEM_PROCESSOR "x86_64" CACHE STRING "Target architecture")

# set the compiler
set(CMAKE_LIBRARY_ARCHITECTURE "x86_64-w64-mingw32")
set(CMAKE_C_COMPILER   "${CMAKE_LIBRARY_ARCHITECTURE}-gcc")
set(CMAKE_CXX_COMPILER "${CMAKE_LIBRARY_ARCHITECTURE}-g++")
set(CMAKE_RC_COMPILER  "${CMAKE_LIBRARY_ARCHITECTURE}-windres")
set(CMAKE_LINKER       "${CMAKE_LIBRARY_ARCHITECTURE}-ld")

# where is the target environment located
# this should be a chroot environment on your system with all the required native libraries
# set(CMAKE_FIND_ROOT_PATH "/usr/local/targets/${CMAKE_LIBRARY_ARCHITECTURE}")
# include_directories("${CMAKE_FIND_ROOT_PATH}/usr/include/${CMAKE_LIBRARY_ARCHITECTURE}")
set(CMAKE_FIND_ROOT_PATH "/home/ilikecola/win32_64/Fast-DDS")
include_directories("${CMAKE_FIND_ROOT_PATH}/include")

# adjust the default behaviour of the FIND_XXX() commands:
# search for programs in the host environment
# search for headers and libraries in the target environment
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

# crosscompiling emulator ( cmake > 3.4 )
# This variable is only used when CMAKE_CROSSCOMPILING is on.
# It should point to a command on the host system that can run
# executables built for the target system. The command will also be
# used to run try_run() generated executables, which avoids
# manual population of the TryRunResults.cmake file.
# It is also used as the default value for the CROSSCOMPILING_EMULATOR
# target property of executables.

# not required on x86_64 systems running i386 code

set(CMAKE_CROSSCOMPILING_EMULATOR /usr/bin/qemu-${CMAKE_SYSTEM_PROCESSOR}-static)

Things seem to be thread model, POSIX model is not properly support mutex.

Thank you very much!

I am going to move this issue to the Unofficial support forum. According to the CONTRIBUTING guidelines, issues related with non-officially supported platforms, architectures and/or compilers should be discussed over that forum.
