[Mingw-users] bison 3.0.2 and m4sugar.m4

[Werner L. <wl...@gn...>]

Folks,


how do I correctly compile bison 3.0.2 with mingw?

The incantation

  ./configure ac_cv_func__set_invalid_parameter_handler=no
  make
  make install

works without glitches, however, calling bison (within the msys shell)
gives me

  $ bison myfile.y
  ...\msys\1.0\local\bin\bison.exe: \
    /usr/local/share/bison/m4sugar/m4sugar.m4: \
    cannot open: No such file or directory

I tried a workaround mentioned in the web, but it still fails:

  $ BISON_PKGDATADIR=.../msys/1.0/local/share/bison \
    bison myfile.y
  ...\msys\1.0\local\bin\bison.exe: \
    m4 subprocess failed: No such file or directory 

(I have a working m4.exe of course)

What is the cause for that, and how can I fix it?  Are there special
parameters necessary for the configure script?  I see that problems
with m4sugar.m4 are present since 10(!) years, and I really wonder why
we still have to struggle with that...
