[slang-users] Import Error with PNG module

[Laurent Perez <perez.l@xxxxxxx>]

Hi,

I got this error when importing png module :

slsh> require ("png");
Error linking to /home/laurent//lib/slang/v2/modules/png-module.so:
/usr/lib/libpng.so.3: undefined symbol: deflate
/home/laurent/share/slsh/png.Sl:2:<top-level>:Import Error

As far as I know, deflate is defined in the zlib library used by png. I
don't know if it is a system error (Slackware 10.1) but changing the
Makefile to force linking with zlib ( PNG_LIB =  -lpng -lz ) made a
working png module.

ldd png-module.so                       
        libpng.so.3 => /usr/lib/libpng.so.3 (0x4001a000)
        libz.so.1 => /usr/lib/libz.so.1 (0x4004c000)
        libm.so.6 => /lib/libm.so.6 (0x4005d000)
        libc.so.6 => /lib/libc.so.6 (0x40080000)
        /lib/ld-linux.so.2 (0x80000000)


Laurent.
