Question

我有一个工具链，而不是在路径上，安装在包含空格（C:\Program Files\Some Compiler\）的位置。我试过了：

env = Environment(
    MY_TOOLCHAIN_ROOT = R'C:\Program Files\Some Compiler\',
    MY_TOOLCHAIN_BIN = R'$MY_TOOLCHAIN_ROOT\bin',
)
env.Replace(
    CC = "$MY_TOOLCHAIN_BIN/gcc",
    CXX = "$MY_TOOLCHAIN_BIN/g++",
    OBJCOPY = "$MY_TOOLCHAIN_BIN/objcopy"
)

env.Program('main.cpp')

但是我收到了错误

'C:\Program' is not recognized as an internal or external command, operable program or batch file.

如何让scons引用空格？

Answer 1

似乎我需要将它们标记为File s：

env.Replace(
    CC = env.File("$MY_TOOLCHAIN_BIN/gcc"),
    CXX = env.File("$MY_TOOLCHAIN_BIN/g++"),
    OBJCOPY = env.File("$MY_TOOLCHAIN_BIN/objcopy")
)

Answer 2

我认为问题在于您使用$的os样式变量。而不是用env.File（）指定它们（我很惊讶它处理变量），你可以考虑一些简单的python代码如下：

import os

env = Environment(
    MY_TOOLCHAIN_ROOT = R'C:\Program Files\Some Compiler\',
    MY_TOOLCHAIN_BIN = R'$MY_TOOLCHAIN_ROOT\bin',
)
env.Replace(
    CC = os.path.join(os.environ["MY_TOOLCHAIN_BIN"], "gcc"),
    CXX = os.path.join(os.environ["MY_TOOLCHAIN_BIN"], "g++"),
    OBJCOPY = os.path.join(os.environ["MY_TOOLCHAIN_BIN"], "objcopy")
)

Scons编译器路径包含空格
