SCONS：LD找不到标准库

Question

我正在与Raylib一起使用SCONS进行建筑。我正在使用clang将编译从Ubuntu（In WSL）交叉到Windows。我的项目目录包含带有raylib二进制文件的lib目录，include与Raylib标头的目录。当我运行SCONS时，我将获得此输出：

scons: Reading SConscript files ...
scons: done reading SConscript files.
scons: Building targets ...
clang++ -o main.o -c -mwindows --target=x86_64-w64-windows-gnu -static -static-libgcc -static-libstdc++ -Iinclude main.cpp
clang: warning: argument unused during compilation: '-mwindows' [-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-static-libgcc' [-Wunused-command-line-argument]
clang: warning: argument unused during compilation: '-static-libstdc++' [-Wunused-command-line-argument]
clang++ -o tiled_test.exe main.o -Llib -lraylib -lopengl32 -lgdi32 -lwinmm
/bin/ld: cannot find -lopengl32
/bin/ld: cannot find -lgdi32
/bin/ld: cannot find -lwinmm
clang: error: linker command failed with exit code 1 (use -v to see invocation)
scons: *** [tiled_test.exe] Error 1
scons: building terminated because of errors.

ld找不到OpenGL32，gli32和winmm。

我的sconstruct文件：

import os

LIBS=['raylib', 'opengl32', 'gdi32', 'winmm']
LIBPATH='./lib'
CCFLAGS='-mwindows --target=x86_64-w64-windows-gnu -static -static-libgcc -static-libstdc++'

env = Environment(CXX='clang++', CPPPATH='./include')
env['ENV']['TERM'] = os.environ['TERM'] # Colored output

env.Program('tiled_test.exe', 'main.cpp', LIBS=LIBS, LIBPATH=LIBPATH, CCFLAGS=CCFLAGS)

直接运行clang ++时，它可以很好地工作。

clang++ main.cpp -o tiled_test.exe -Iinclude -Llib -mwindows --target=x86_64-w64-windows-gnu -static -static-libgcc -static-libstdc++ -lraylib -lopengl32 -lgdi32 -lwinmm

我找到了我问题的答案。根据 this 默认情况下，SCONS不使用Shell的PATH。用户需要将其添加到环境中。

我固定的sconstruct文件：

import os

LIBS=['raylib', 'opengl32', 'gdi32', 'winmm']
LIBPATH='./lib'
CCFLAGS='-static --target=x86_64-w64-windows-gnu'
LINKFLAGS = '-mwindows --target=x86_64-w64-windows-gnu -static-libgcc -static-libstdc++'

env = Environment(CXX='clang++', CPPPATH='./include', tools = ['mingw'], ENV = {'PATH' : os.environ['PATH']})
env['ENV']['TERM'] = os.environ['TERM'] # Colored output

env.Program('tiled_test.exe', 'main.cpp', LIBS=LIBS, LIBPATH=LIBPATH, CCFLAGS=CCFLAGS, LINKFLAGS=LINKFLAGS)
