# # tested on | Windows native | Linux cross-compilation # ------------------------+-------------------+--------------------------- # MSVS C++ 2010 Express | WORKS | n/a # Mingw-w64 | WORKS | WORKS # Mingw-w32 | WORKS | WORKS # MinGW | WORKS | untested # ##### # Notes about MSVS C++ : # # - MSVC2010-Express compiles to 32bits only. # ##### # Notes about Mingw-w64 and Mingw-w32 under Windows : # # - both can be installed using the official installer : # http://mingw-w64.sourceforge.net/download.php#mingw-builds # # - if you want to compile both 32bits and 64bits, don't forget to # run the installer twice to install them both. # # - install them into a path that does not contain spaces # ( example : "C:/Mingw-w32", "C:/Mingw-w64" ) # # - if you want to compile faster using the "-j" option, don't forget # to install the appropriate version of the Pywin32 python extension # available from : http://sourceforge.net/projects/pywin32/files/ # # - before running scons, you must add into the environment path # the path to the "/bin" directory of the Mingw version you want # to use : # # set PATH=C:/Mingw-w32/bin;%PATH% # # - then, scons should be able to detect gcc. # - Mingw-w32 only compiles 32bits. # - Mingw-w64 only compiles 64bits. # # - it is possible to add them both at the same time into the PATH env, # if you also define the MINGW32_PREFIX and MINGW64_PREFIX environment # variables. # For instance, you could store that set of commands into a .bat script # that you would run just before scons : # # set PATH=C:\mingw-w32\bin;%PATH% # set PATH=C:\mingw-w64\bin;%PATH% # set MINGW32_PREFIX=C:\mingw-w32\bin\ # set MINGW64_PREFIX=C:\mingw-w64\bin\ # ##### # Notes about Mingw, Mingw-w64 and Mingw-w32 under Linux : # # - default toolchain prefixes are : # "i586-mingw32msvc-" for MinGW # "i686-w64-mingw32-" for Mingw-w32 # "x86_64-w64-mingw32-" for Mingw-w64 # # - if both MinGW and Mingw-w32 are installed on your system # Mingw-w32 should take the priority over MinGW. # # - it is possible to manually override prefixes by defining # the MINGW32_PREFIX and MINGW64_PREFIX environment variables. # ##### # Notes about Mingw under Windows : # # - this is the MinGW version from http://mingw.org/ # - install it into a path that does not contain spaces # ( example : "C:/MinGW" ) # - several DirectX headers might be missing. You can copy them into # the C:/MinGW/include" directory from this page : # https://code.google.com/p/mingw-lib/source/browse/trunk/working/avcodec_to_widget_5/directx_include/ # - before running scons, add the path to the "/bin" directory : # set PATH=C:/MinGW/bin;%PATH% # - scons should be able to detect gcc. # ##### # TODO : # # - finish to cleanup this script to remove all the remains of previous hacks and workarounds # - make it work with the Windows7 SDK that is supposed to enable 64bits compilation for MSVC2010-Express # - confirm it works well with other Visual Studio versions. # - update the wiki about the pywin32 extension required for the "-j" option under Windows. # - update the wiki to document MINGW32_PREFIX and MINGW64_PREFIX # import os import sys def is_active(): return True def get_name(): return "Windows" def can_build(): if (os.name=="nt"): #building natively on windows! if (os.getenv("VSINSTALLDIR")): return True else: print("\nMSVC not detected, attempting Mingw.") mingw32 = "" mingw64 = "" if ( os.getenv("MINGW32_PREFIX") ) : mingw32 = os.getenv("MINGW32_PREFIX") if ( os.getenv("MINGW64_PREFIX") ) : mingw64 = os.getenv("MINGW64_PREFIX") test = "gcc --version > NUL 2>&1" if os.system(test)!= 0 and os.system(mingw32+test)!=0 and os.system(mingw64+test)!=0 : print("- could not detect gcc.") print("Please, make sure a path to a Mingw /bin directory is accessible into the environment PATH.\n") return False else: print("- gcc detected.") return True if (os.name=="posix"): mingw = "i586-mingw32msvc-" mingw64 = "x86_64-w64-mingw32-" mingw32 = "i686-w64-mingw32-" if (os.getenv("MINGW32_PREFIX")): mingw32=os.getenv("MINGW32_PREFIX") mingw = mingw32 if (os.getenv("MINGW64_PREFIX")): mingw64=os.getenv("MINGW64_PREFIX") test = "gcc --version &>/dev/null" if (os.system(mingw+test) == 0 or os.system(mingw64+test) == 0 or os.system(mingw32+test) == 0): return True return False def get_opts(): mingw="" mingw32="" mingw64="" if ( os.name == "posix" ): mingw = "i586-mingw32msvc-" mingw32 = "i686-w64-mingw32-" mingw64 = "x86_64-w64-mingw32-" if os.system(mingw32+"gcc --version &>/dev/null") != 0 : mingw32 = mingw if (os.getenv("MINGW32_PREFIX")): mingw32=os.getenv("MINGW32_PREFIX") mingw = mingw32 if (os.getenv("MINGW64_PREFIX")): mingw64=os.getenv("MINGW64_PREFIX") return [ ('mingw_prefix','Mingw Prefix',mingw32), ('mingw_prefix_64','Mingw Prefix 64 bits',mingw64), ] def get_flags(): return [ ('freetype','builtin'), #use builtin freetype ('openssl','builtin'), #use builtin openssl ] def build_res_file( target, source, env ): cmdbase = "" if (env["bits"] == "32"): cmdbase = env['mingw_prefix'] else: cmdbase = env['mingw_prefix_64'] CPPPATH = env['CPPPATH'] cmdbase = cmdbase + 'windres --include-dir .
