waf如何使用多版本tricore-gcc.exe编译器

Question

我想对 windows OS

中的不同项目使用不同的 tricore-gcc.exe

这两个 tricore-gcc.exe 在以下路径中，但不在 PATH 中：

C:\HighTec\toolchains\tricore\v4.6.3.0\bin\tricore-gcc.exe
C:\HighTec\toolchains\tricore\v4.9.2.0\bin\tricore-gcc.exe

我的问题是如何在waf中配置它？

compiler_c是否只搜索msvc、gcc和clang？

感谢任何建议！

（我在 Whosebug 中搜索过，例如但我没有找到关于如何在 Windows 中设置绝对路径的答案）

我的wscript:


def options(opt):
    print("start opt ------------------")
    opt.load('compiler_c')

def configure(conf):
    # here we are in default variant/env
    # we load the default compiler, probably gcc
    conf.load('compiler_c')

    # config for tricore 4.6.3 variant
    print("start ------------------")
    conf.setenv('t463')
    conf.env.CC = ['C:\HighTec\toolchains\tricore\v4.6.3.0\bin\tricore-gcc.exe']

    conf.load('compiler_c')

    # config for tricore 4.9.2 variant
    print("start ------------------")
    conf.setenv('t492')
    conf.env.CC = ['C:\HighTec\toolchains\tricore\v4.9.2.0\bin\tricore-gcc.exe']

    conf.load('compiler_c')

    # back to default config
    conf.setenv('')

def build(bld):

    bld.program(source = 'main.c', target = 'myexe')

# this create variants commands and build directories

from waflib.Build import (
    BuildContext,
    CleanContext,
    InstallContext,
    UninstallContext,
)

for variant in ['t463', 't492']:
    for context in [BuildContext, CleanContext, InstallContext, UninstallContext]:

        name = context.__name__.replace('Context','').lower()

        class tmp(context):
            cmd = name + '_' + variant
            variant = variant

我测试了一下，得到结果：

是的，waf 只检测 compiler_c 中定义的受支持的编译器。

如果你的编译器是“兼容的”，因为 clang 与 gcc 兼容（即它的命令行工作相同）那么你只需要定义 CC:

from waflib import Logs

# this is to check only for gcc-like compiler, on win32, compiler_c begins with msvc
from waflib.Tools.compiler_c import c_compiler
c_compiler['win32'] = ['gcc']

def options(opt):
    opt.load('compiler_c')

def configure(conf):

    conf.setenv('t463')
    conf.env.CC = ['c:/toolchains/tricore/v4.6.3.0/bin/tricore-gcc.exe']
    conf.load('compiler_c')

    conf.setenv('t492')
    conf.env.CC = ['c:/toolchains/tricore/v4.9.2.0/bin/tricore-gcc.exe']
    conf.load('compiler_c')

def build(bld):

    Logs.info("Using compiler {}".format(bld.env.CC))
    bld.program(source = 'main.c', target = 'myexe')

注意：我在 Linux 上测试过，没有可用的 win32 机器:)

要检测新的“不兼容”编译器，您必须执行以下操作：

from waflib.Tools.compiler_c import c_compiler
c_compiler['win32'] = ['tricore', 'msvc', 'gcc']

def options(opt):
    opt.load('compiler_c')
def configure(cnf):
    cnf.load('compiler_c')
def build(bld):
    bld.program(source='main.c', target='myexe')

并定义一个tricore工具来检测编译器：

# from waflib/Tools/clang.py

from waflib.Tools import ccroot, ar, gcc
from waflib.Configure import conf

@conf
def find_tricore(conf):
    cc = conf.find_program('tricore', var='CC')
    conf.get_cc_version(cc)
    conf.env.CC_NAME = 'tricore'

def configure(conf):
    conf.find_tricore()
    conf.find_ar()
    conf.gcc_common_flags()
    conf.gcc_modifier_platform()
    conf.cc_load_tools()
    conf.cc_add_flags()
    conf.link_add_flags()

您可以查看 gcc.py、clang.py、suncc.py 或 icc.py 以获得像 gcc 这样的编译器。查看 msvc.py 以了解与 gcc 真正不同的编译器。
