[Scons-users] StaticLibrary problems

[Mats Wichmann]

To follow up, for the testcase I hacked together, which was about 500 
trivial source files (and a 10.000 char command line), it definitely 
failed if I forced the toolchain to be mingw.  By adding a revised 
version of the $ARCOM variable we can get a command file to be created, 
and be passed to ar, but this failed due to the backslashes in pathnames 
in the file, which ar doesn't like.  So an extra step was needed to get 
the file contents translated, for which there's a recipe in the manpage at:

https://scons.org/doc/production/HTML/scons-man.html#cv-TEMPFILEARGESCFUNC

So with this SConstruct my test builds the archive without complaint, 
with the actual issued command sequence looking like this:

scons: Building targets ...
Using tempfile C:\Users\mats\AppData\Local\Temp\tmp6eo3tx2i.lnk for 
command line:
ar rc libboo.a src/lib/00gsd.o src/lib/015r89p3.o src/lib/04mj84.o 
src/lib/06uml3.o ... [lots snipped]
ar @C:\Users\mats\AppData\Local\Temp\tmp6eo3tx2i.lnk
ranlib libboo.a
scons: done building targets.


And the SConstruct:

import sys
import re
from SCons.Subst import quote_spaces

WINPATHSEP_RE = re.compile(r"\\([^\"'\\]|$)")

def escaper(arg):
     arg = quote_spaces(arg)
     if sys.platform != "win32":
         return arg
     return WINPATHSEP_RE.sub(r"/\1", arg)

env = Environment(CPPPATH='src/include', tools=["mingw"])
env.Replace(ARCOM="${{TEMPFILE('{0}', '')}}".format(env['ARCOM']))
env.Replace(TEMPFILEARGESCFUNC=escaper)
env.StaticLibrary(target='boo', source=Glob('src/lib/*.c'))


Hope this provides some help getting you back on the air...
