Hi Jason,
Didn't check new premake yet, just comment about premake4, in case you
haven't consider it. We're working with bunch of platforms, and one of the
issues I ran into was setting different GCC compilers. I figured out the
way to specify it thru 'newoption'. This works pretty well, but it would be
nice if there is way to script these settings in the way that can be shared
with others. For example Qt has mkspecs where defaults for different
compilers are set and qmake scripts use it for building. Anyhow snippet of
how I'm setting GCC "flavor" in premake script is attached below.
Branimir
newoption {
trigger = "gcc",
value = "GCC",
description = "Choose GCC flavor",
allowed = {
{ "default", "Default GCC will be used." },
{ "mingw", "MinGW" },
{ "nacl", "Google Native Client" },
{ "android-arm7", "Google Android NDK" },
{ "clang", "Clang LLVM compiler" },
}
}
-- Avoid error when invoking premake4 --help.
if (_ACTION == nil) then return end
if _ACTION == "gmake" then
if nil == _OPTIONS["gcc"] then
print("GCC flavor must be specified!")
os.exit(1)
end
if "default" == _OPTIONS["gcc"] then
location (BUILD_DIR .. "projects/" .. _ACTION .. "-default")
end
if "mingw" == _OPTIONS["gcc"] then
if not os.getenv("MINGW") then
print("Set MINGW enviroment variables.")
end
premake.gcc.cc = "$(MINGW)/bin/mingw32-gcc"
premake.gcc.cxx = "$(MINGW)/bin/mingw32-g++"
premake.gcc.ar = "$(MINGW)/bin/ar"
location (BUILD_DIR .. "projects/" .. _ACTION .. "-mingw")
end
if "nacl" == _OPTIONS["gcc"] then
if not os.getenv("NACL") then
print("Set NACL enviroment variables.")
end
premake.gcc.cc = "$(NACL)/bin/x86_64-nacl-gcc"
premake.gcc.cxx = "$(NACL)/bin/x86_64-nacl-g++"
premake.gcc.ar = "$(NACL)/bin/x86_64-nacl-ar"
location (BUILD_DIR .. "projects/" .. _ACTION .. "-nacl")
end
if "android-arm7" == _OPTIONS["gcc"] then
if not os.getenv("ANDROID_NDK") then
print("Set ANDROID_NDK envrionment variables.")
end
premake.gcc.cc = "$(ANDROID_NDK)/bin/arm-linux-androideabi-gcc"
premake.gcc.cxx = "$(ANDROID_NDK)/bin/arm-linux-androideabi-g++"
premake.gcc.ar = "$(ANDROID_NDK)/bin/arm-linux-androideabi-ar"
location (BUILD_DIR .. "projects/" .. _ACTION .. "-android-arm7")
end
if "clang" == _OPTIONS["gcc"] then
if not os.getenv("LLVM") or not os.getenv("MINGW") then
print("Set LLVM and MINGW enviroment variables.")
end
premake.gcc.cc = "$(LLVM)/bin/clang"
premake.gcc.cxx = "$(LLVM)/bin/clang++"
premake.gcc.ar = "$(MINGW)/bin/ar"
location (BUILD_DIR .. "projects/" .. _ACTION .. "-clang")
end
end
