This list likely hates me by now. Now I am unable to get past ZLIB. ZLib is indeed installed on my system.
/usr/lib/libz.a /usr/lib/libz.so /usr/lib64/libz.a /usr/lib64/libz.so are the various places it lives and I am on version 1.2.3 of Zlib. However, the configure script bombs with: checking for ZLIB support... yes checking if the location of ZLIB install directory is defined... no checking for gzgets in -lz... no configure: error: ZLIB extension requires zlib >= 1.0.9 I have tried the flag -with-zlib-dir= with /usr/lib64, /usr/lib, and /usr/include and it still fails. Config.log ends with configure:22706: checking for ZLIB support configure:22753: checking if the location of ZLIB install directory is defined configure:23188: checking for gzgets in -lz configure:23207: gcc -o conftest -g -O2 -L/usr/kerberos/lib64 conftest.c -lz -lpcre -lresolv -lm -ldl -lnsl -lxml2 -lz -lm -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lssl -lcrypto -ldl -lz 1>&5 /usr/bin/ld: skipping incompatible /usr/lib/libcom_err.so when searching for -lcom_err /usr/bin/ld: skipping incompatible /usr/lib/libcom_err.a when searching for -lcom_err /usr/bin/ld: cannot find -lcom_err collect2: ld returned 1 exit status configure: failed program was: #line 23196 "configure" #include "confdefs.h" /* Override any gcc2 internal prototype to avoid an error. */ /* We use char because int might match the return type of a gcc2 builtin and then its argument prototype would still apply. */ char gzgets(); int main() { gzgets() ; return 0; } I saw krb5 was listed in there so I made sure krb5-libs and krb5-devel were installed too. Any ideas? Thanks!
