[Sablevm-developer] building out-of-the-box on non-Linux platform

[David <db...@cs...>]

Hi,

I think it would be great if SableVM could be built out-of-the-box on
all platforms including the non-Linuxian FreeBSD and OS X.  It will
simplify my life as I want to build and test on these platforms.
Currently source code is not an issue, it is more a configure/Makefile
isssue.

src/libsablevm/Makefile.am has some line like:
libsablevm_la_LIBADD =3D -lpthread -lm -lffi -lltdl -lrt

FreeBSD does not like -lpthread.
OS X does not like -lrt.

This is because functionnality is located elsewhere and there are
no such libXX.so file...  (Actually, on OS X, there is a single
libSystem that includes implementation of libc, libm, libpthread and
probably others.  libc etc. are only symlinks to libSystem.  But there
are no librt symlinks in the default installation)

A long time ago, I had:
if REQ_LPTHREAD
REQ_LIBS =3D -lpthread -lm -lffi -lltdl -lrt
else
REQ_LIBS =3D -lc_r -lm -lffi -lltdl -lrt
endif
libsablevm_la_LIBADD =3D ${REQ_LIBS}

where REQ_LPTHREAD was set in ./configure.ac.

This was ok for FreeBSD but will become more complex with -lrt on/off.
Note: I tried first with simpler things but automake/conf tools didn't
like it.  There are some restriction of what the right hand side arg
of libsablevm_la_LIBADD can be for the autoconf/make tools, don't
remember which one.

I will play more with it but any help/advice from autoconf/make expert
would be appreciated on the best way it could be done.
