Hi all: when compiling on x64 systems (i.e. CentOS & Fedora core 10) and using the BUILD/compile-pentium64-max, I'm getting the -lz error "/usr/bin/ld: cannot find -lz" and when I simplify the ./comfigure line to a --without-zlib it works. So, after modifing the configure flags that results into: ./configure --prefix=/u02/local/mysql-5.1.34 --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-plugins=max --with-embedded-server --with-mysqld-ldflags=-all-static --with-client-ldflags=-all-static --without-zlib --enable-local-infile It still has problems with the -lz flag, so does anybody know what is bringing the -lz into the configure? Note: I've also tried --with-zlibdir=/usr/lib64, but same error. Thanks tons.
