Subject: slang0.99.34: problems for use in "unstable"
Mime-Version: 1.0
Content-Type: text/plain; charset=us-ascii
X-Mailer: Mutt 0.74

Package: slang0.99.34
Version: 0.99.38-2

Hi Chris.

The S-Lang library is dynamically linked to libc's math library: [0]
	penguin ray 18:09 ~> ldd /usr/lib/libslang.so.0.99.38
		libm.so.5 => /lib/libm.so.5 (0x4004e000)

While this is desirable (it reduces memory usage), it prevents its use with
libc6.

Take the test program used by mutt-0.74's configure to see if S-Lang works:
--- begin ---
int main() {
init_SLang ();
; return 0; }
--- end ---

Trying to compile this results in problems:
	$ gcc blub.c -lslang
	/lib/libm.so.5: undefined reference to `__getfpucw'
	$ nm --print-file-name --defined-only --dynamic /lib/lib*so* | grep '__getfpuc>
	/lib/libc.so.5:000696ec T __getfpucw
	/lib/libc.so.5.4.23:000696ec T __getfpucw

The best solution for this would be to provide a version of S-Lang linked
against libc6 for unstable; if this is not yet an option for you, a
temporary solution is not to link S-Lang dynamically against libm:
