用MinGW命令长命令行TEMPFILE [英] SCons long command line TEMPFILE with MinGW

问题描述

我正在尝试在Windows上使用SCons和MinGW从gcc和gfortran对象构建共享库，但是在最终链接期间，命令行太长，超过18000个字符.我知道我需要使用一个临时文件(响应文件?)来传递命令行，但是我找不到让SCons直接执行此操作的方法.我在该库中使用CMake，它在没有干扰的情况下处理了响应文件.

I'm trying to build a shared library from gcc and gfortran objects using SCons and MinGW on Windows, but during the final link the command line is too long, in excess of 18000 characters. I know I need to use a tempfile (response file?) to pass the command line, but I can't find a way to get SCons to do this directly. I was using CMake for this library and it handled the response file without my interference.

SCons似乎正在使用CommandGeneratorAction生成共享库命令行.有没有办法告诉该操作使用响应文件机制?还有另一种方法可以处理我忽略的长命令行吗?

SCons appears to be using the CommandGeneratorAction to generate the shared library command line. Is there a way to tell this action to use the response file mechanism? Is there another method for handling long command lines that I'm overlooking?

相关的SConscript:

Relevant SConscript:

sqllib = env.SharedLibrary(target='fvssql', source=sqllib_sources, LIBS=['odbc32',])
ffelib = env.SharedLibrary(target='fvspncffe', source=ffelib_sources, LIBS=[sqllib,], LIBPATH=['.',])

fvsobjs = env.SharedObject(fvslib_sources)
fvsobjs = [obj for obj in fvsobjs if obj.get_suffix()=='.o']

fvslib = env.SharedLibrary(target='fvspnc', source=fvsobjs, LIBS=sqllib+ffelib, LIBPATH=['.',])

env.Dump()的相关输出:

Relevant output from env.Dump():

'SHLIBSUFFIX': '.dll',
'SHLINK': '$LINK',
'SHLINKCOM': <SCons.Action.CommandGeneratorAction object at 0x02DDF770>,
'SHLINKFLAGS': ['$LINKFLAGS', '-shared'],

我可以在环境env['SHLINKCOM']="${TEMPFILE('$SHLINK -o $TARGET ... $SOURCE')}"中准备命令行模板，但这似乎很脆弱，如果可能的话，我宁愿让SCons对其进行处理.

I could prepare the command line template in my environment env['SHLINKCOM']="${TEMPFILE('$SHLINK -o $TARGET ... $SOURCE')}", but this seems fragile and I'd prefer to let SCons handle it if possible.

我尝试使用字符串替换env['SHLINKCOM']='${TEMPFILE("%s")}' % (env['SHLINKCOM'],)，但是结果是命令行不完整，现在无论如何都响应文件.

I tried using string substitution env['SHLINKCOM']='${TEMPFILE("%s")}' % (env['SHLINKCOM'],), but the result was an incomplete command line and now response file anyhow.

编辑

我已经看到了 LongCmdLinesOnWin32 解决方法.如果可能的话，我宁愿使用TEMPFILE，TempFileMunge，命令行间接机制.

I have seen the LongCmdLinesOnWin32 workaround. I would prefer to use the TEMPFILE, TempFileMunge, commandline indirection mechanism if possible.

您是否看到过 http://scons.org /wiki/LongCmdLinesOnWin32 ?在链接阶段，长命令处理似乎可以解决您的确切问题.

Have you seen http://scons.org/wiki/LongCmdLinesOnWin32? It looks like there is an answer to your exact problem with long command ling during the link phase.
