Missing OpenBSD support

[jpellegrini]

@egallesio -- this is fixed by PR #376

When compiling under OpenBSD, the .so files for SRFIs are not generated.

openbsd$ ls -l lib/srfi/*.so
ls: lib/srfi/*.so: No such file or directory

This is what I did to compile for OpenBSD:

$ export AUTOMAKE_VERSION=1.16
$ export AUTOCONF_VERSION=2.69
$ autoreconf
$ ./configure CFLAGS="-g -Wall -O2" CC=egcc
$ gmake
# gmake install
$ gmake test

Ah. The $(SO) variable is being translated into the empty string on OpenBSD! This is the cause of the problem:

egcc -g -Wall -O2   -I../../src -I/usr/local/include  -c -o 132.o 132.c
:   132. 132.o 
../../utils/tmpcomp -o 95.ostk 95.stk
egcc -g -Wall -O2   -I../../src -I/usr/local/include  -c -o 25.o 25.c
:   25. 25.o

Same seems to happen with clang.

It's ld not being called?

In Linux:

../../utils/tmpcomp -C -o 25-incl.c 25.stk
gcc -g -O0 -Wall  -fpic -nostdlib -I../../src   -c -o 25.o 25.c
ld -shared -o  25.so 25.o 

OpenBSD:

../../utils/tmpcomp -C -o 25-incl.c 25.stk
clang -g -Wall -O2   -I../../src -I/usr/local/include -I../../gmp -c -o 25.o 25.c
:   25. 25.o 

[jpellegrini]

Yes.
In srfi/Makefile,

Linux:

SH_LIB_SUFFIX = so
SH_LOADER = ld
SH_LOAD_FLAGS = -shared -o
SH_MAIN_LOAD_FLAGS = -rdynamic
SH_SUFFIX = so

OpenBSD:

SH_LIB_SUFFIX =
SH_LOADER = :
SH_LOAD_FLAGS =
SH_MAIN_LOAD_FLAGS =
SH_SUFFIX =

Interesting - FreeBSD correctly sets the variables. And loads SRFIs 25, 132 etc without problems.

I got STklos to compile and pass all tests in OpenBSD (the problem was just that OpenBSD was missing in utils/shlib-options; I'll include this in the OpenBSD PR (#376 )

[jpellegrini]

PR #376 now adds support for OpenBSD. For STklos to run ok on OpenBSD only one thingis missing: SRFI 144 (see #374 )
