I am using edgy which comes with ruby 1.8.4. I need to use 1.8.5.
So I tried to compile it from sources.
I find that for example zlib, readline etc dont work.
Went into the ext/zlib directory and found that mkmf.log contains things like



have_library: checking for deflateReset() in -lz... -------------------- yes

"gcc -o conftest -I../.. -I../../. -I../.././ext/zlib -g -O2 conftest.c -L'../..' -rdynamic -Wl,-export-dynamic -lruby-static -lz -ldl -lcrypt -lm -lc"
conftest.c: In function `t'
conftest.c:3: error: `deflateReset' undeclared (first use in this function)
conftest.c:3: error: (Each undeclared identifier is reported only once
conftest.c:3: error: for each function it appears in.)
checked program was:
/* begin */
1: /*top*/
2: int main() { return 0; }
3: int t() { void ((*volatile p)()); p = (void ((*)()))deflateReset; return 0; }
/* end */


Note that Ive got zlib and zlib1g installed that put files like zlib.h and zconf.h in /usr/include
