Description
With the current configure.ac and src/Makefile.am, libtool fails to build libonig-5.dll when using a plain vanilla msys2 + mingw64 toolchain on windows 10 x64.
To build a usable oniguruma, I need to use sed , autoreconf -fi, make src dll, strip the libtool created dll, and finally copy the libonig.def file to the install bin/ dir as in my build helper https://github.com/jonforums/buildlets/blob/master/build_oniguruma.ps1#L45-L72
The problem is that the libonig_la_LDFLAGS does not include -no-undefined when the --build triplet (os portion) contains mingw*.
PCRE2 solves this problem with the following autotools config:
### file: Makefile.am
if WITH_PCRE2_8
libpcre2_8_la_LDFLAGS = $(EXTRA_LIBPCRE2_8_LDFLAGS)
endif # WITH_PCRE2_8
---
### file: configure.ac
# Platform specific issues
NO_UNDEFINED=
EXPORT_ALL_SYMBOLS=
case $host_os in
cygwin* | mingw* )
if test X"$enable_shared" = Xyes; then
NO_UNDEFINED="-no-undefined"
EXPORT_ALL_SYMBOLS="-Wl,--export-all-symbols"
fi
;;
esac
...
EXTRA_LIBPCRE2_8_LDFLAGS="$EXTRA_LIBPCRE2_8_LDFLAGS \
$NO_UNDEFINED -version-info libpcre2_8_version"Metadata
