Hi, I hope someone can point me in the right direction here. I am trying to build FR version 2.1.12 with the option "--with-experimental-modules" on Debian Linux Squeeze 2.6.32-5-amd64 because I need to build support for Wimax stuff. However I get the following compiling error(s): === checking openssl/hmac.h usability... no checking openssl/hmac.h presence... no checking for openssl/hmac.h... no configure: WARNING: silently not building rlm_wimax. configure: WARNING: FAILURE: rlm_wimax requires: openssl/hmac.h. configure: creating ./config.status config.status: creating Makefile === and however when I launch FR, this is what I get: === /usr/local/etc/raddb/modules/wimax[92]: Failed to link to module 'rlm_wimax': rlm_wimax.so: cannot open shared object file: No such file or directory /usr/local/etc/raddb/sites-enabled/default[122]: Failed to load module "wimax". /usr/local/etc/raddb/sites-enabled/default[69]: Errors parsing authorize section. === I am trying to build the FreeRadius package version version 2.1.12 from sources from the official tarball from freeradius.org. I know I am missing something but I have looked almost everywhere and can not get a proper clue to this. Regards,
