Autoconf fails to build with MSYS2 (MINGW64) #27

Closed chestertonic closed 2 years ago

chestertonic commented 2 years ago

When running ./build-djgpp default (or any other variant) the build always fails at:

make[3]: Leaving directory '/home/Chester/build-djgpp/build/djcross-gcc-10.3.0/autoconf-2.69/lib/m4sugar'
autom4te_perllibdir='..'/lib AUTOM4TE_CFG='../lib/autom4te.cfg'         ../bin/autom4te -B '..'/lib -B '..'/lib         --language M4sh --cache '' --melt ./autoconf.as -o autoconf.in
The system cannot find the path specified.
autom4te: need GNU m4 1.4 or later: /usr/bin/m4
make[2]: *** [Makefile:641: autoconf.in] Error 1
make[2]: Leaving directory '/home/Chester/build-djgpp/build/djcross-gcc-10.3.0/autoconf-2.69/bin'
make[1]: *** [Makefile:357: all-recursive] Error 1
make[1]: Leaving directory '/home/Chester/build-djgpp/build/djcross-gcc-10.3.0/autoconf-2.69'
make: *** [Makefile:292: all] Error 2

Seems that this type of failure is common across all platforms but can't seem to find a solution.

Hi, thanks for the report.

Do you have M4 installed? pacman -Syuu m4 should resolve it. I thought package base-devel included M4, apparently it doesn't. I'll list it in the readme.

chestertonic commented 2 years ago

I believe m4 is pulled in as a dependency of packages in base-devel as I checked for it's existence after getting the error message. Looking at the MSYS2 and MINGW packages for autoconf shows a number of patches to make it work on Windows. I'm not sure if any of those patches will help.

Looks like autoconf was picking up /mingw64/bin/perl instead of /usr/bin/perl expected by M4. Not sure if one of the dependencies listed pulled in /mingw64/bin/perl or I had previously installed it. I just did an export PERL=/usr/bin/perl before calling build-djgpp.sh and the build succeeded.

Hi again, sorry, haven't had much time for coding lately.

Good to hear you figured it out, weird though that the mingw64 perl isn't compatible with M4/autoconf. I suppose I could put that export PERL=/usr/bin/perl line in the script when building on mingw-w64.
