Hi Andreas,
We'd definitely like to support Solaris. I'm surprised that it
doesn't support strdup() - it's pretty widely-supported (it comes from
4.4BSD, and I thought Solaris got all of that stuff via SunOS).
You can add an implementation like this:
char *strdup(const char *in)
{
size_t len = strlen(in);
char *out = malloc(len+1);
strcpy(out, in);
return out;
}
If you declare that as static and pop it in runtime.c with #ifdef
__solaris__ around it, then it should work fine. Let me know about
any GNUisms in the makefiles. We test regularly on GNU/Linux and
FreeBSD, which use different /bin/sh (bash and pdksh, I believe) so we
catch most of them, but there may be some missing.
