I have a static binary linked against GnuTLS, o.a., that fails to run when
built on OpenBSD 5.8. The program appears to crash even before it's able to
start.
I run:
OpenBSD 5.8-current (GENERIC.MP) #0: Fri Oct 9 18:37:33 CEST 2015
[email protected]:/usr/src/sys/arch/amd64/compile/GENERIC.MP
(built from src.tar.gz of the OpenBSD 5.8 CD with patches 001, 002, 003 and
004 applied)
Since linking GnuTLS is optional for my program I decided to leave it out and
the problem went away. No other libraries appear to cause problems.
To demonstrate the problem I tried to create a program, as small as possible,
statically linked against GnuTLS that shows the failure. I used the following
source/Makefile file, and include some basic output of building/running the
program.
*) source file static_test.c:
#include <gnutls/gnutls.h>
int
main(int argc, char **argv)
{
gnutls_global_init();
gnutls_global_deinit();
return (0);
}
*) Makefile:
CFLAGS+= -I/usr/local/include
LDFLAGS+= -L/usr/local/lib
LDADD+= -static
LDADD+= -lgnutls
LDADD+= -liconv -lintl -lz
LDADD+= -lp11-kit -lffi
