[Swftools-common] compiling development snapshot on FC4 or rendering an image from swf file

[Adam Plumb]

hi all,

I've been tasked with programmatically retrieving a png image from a single-framed swf file.  This is going to be done on an aging Fedora Core 4 server.

The way I've figured that I can do this is by compiling the swfrender module in the swftools development snapshot (9/22).  Unfortunately, I've hit a snag that I'm not really sure how to fix.  I'm able to run ./configure to completion, but when I try to make, I get the following error....

png2swf.c:166: warning: pointer targets in passing argument 1 of '__builtin_strcmp' differ in signedness

I'm not a C programmer, so I'm not really sure how to fix this.  Is this a gcc version issue?  When I run gcc -v, I get gcc version 4.0.2 20051125 (Red Hat 4.0.2-8)

BTW, if swfrender is not the correct tool for this job, I'd appreciate it if someone could point me in the right direction.

Thanks!
