[cl-gd-devel] problem compiling cl-gd-glue.c on 64-bit sytem
by Jeff Cunningham 17 Oct '08

Has anyone had a problem compiling the cl-gd-glue.c into the shared library on a 64-bit system? It's never given me any problem on 32-bit systems, and I could swear I've done it on a 64-bit AMD Debian system before, but I just tried it on a new one and got this error: make gcc -I/usr/local/include -fPIC -c cl-gd-glue.c ld -shared -lgd -lz -lpng -ljpeg -lfreetype -liconv -lm -lc cl-gd-glue.o -o cl-gd-glue.so -L/usr/local/lib ld: /usr/local/lib/libz.a(compress.o): relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libz.a: could not read symbols: Bad value make: *** [cl-gd-glue.so] Error 1 I'm trying to install cl-gd-0.5.6 straight from Edi's site. gd-2.0.35 is installed, along with the other dependencies. This is puzzling. Jeff

[cl-gd-devel] PNG compression

I was experimenting with write-png-to-stream trying :compression-level from -1 to 9 but it doesn't change the size of the image. For jpeg quality level works though. What can I check for PNG compression to work? Thank you, Andrew

Thanks for catching that. Will be fixed in the next release. > Thanks for yet another great library, You're welcome... :)
