Open-source Languages & Tools for z/OS

I have installed zlib 1.2.8 and have compiled a little test program I found. Basically it calls deflateInit2, deflate and deflateEnd. The trouble starts when I try to link it, I get:

export _LD_SYSLIB="//‘SYS1.CSSLIB’://‘CEE.SCEELKEX’://‘CEE.SCEELKED’://‘SYS1.SIEASID’://‘CEE.SCEECPP’://‘CBC.SCCNOBJ’"; export _LD_SYSIX=/usr/local/lib/libz.1.2.8.x;

None of the symbols in error appear in my code, so what have I done wrong?

Thanks

I have just discovered that IBM ship a version of zlib and changing my makefile to use that resulted in the little sample program “Just Working”. So I guess that is the way I will go.

Thanks
