| |
I'm working on a function that uses zlib in the kernel, and I know of other places zlib is used (ppp_deflate, jffs2, mcore). I would expect more users to come along.
I would like to propose putting zlib in the lib directory and making it optionally compile if it is needed. It's pretty easy to move the files around and make a few small changes to the code. However, how do I configure such a thing? I could add something like:
if [ "$CONFIG_PPP_DEFLATE" = "y" ]; then define_tristate CONFIG_ZLIB y fi if [ "$CONFIG_PPP_DEFLATE" = "m" ]; then if [ "$CONFIG_ZLIB" != "y" ]; then define_tristate CONFIG_ZLIB m fi fi
to every place that uses it, or I could put something like:
if [ "$CONFIG_JFFS2_FS" = "y" \ -o "$CONFIG_PPP_DEFLATE" = "y" ]; then define_tristate CONFIG_ZLIB y else if [ "$CONFIG_JFFS2_FS" = "m" \ -o "$CONFIG_PPP_DEFLATE" = "m" ]; then define_tristate CONFIG_ZLIB m fi fi
at the end of the config. I would prefer the latter, but there is not an "end of config" place, you would have to put it at the end of every config.in (about 15 architectures right now). I propose to add a Config.in to the lib directory that is sourced at the end of every config.in for the architectures. I'll do the work if it's willing to be accepted into the kernel.
