There is no pcap installed on my machine, and configure has detected that correctly. However, there are two functions at the end of pcap.c which are not included in the "#ifdef HAVE_LIBPCAP" and for that reason, the compiler creates errors. If you simply put everything in pcap.c between the "#ifdef HAVE_LIBPCAP" and "#endif", everything works well on my machine.

I've pushed a fix. Thanks - I have tested it, it works great.

2. The configuration for types/rlm_eap_pwd does not yet work:

...

I am sure that ec.h is in the directory where it should be.

Is it in the directories which are printed out above?

What does the "config.log" file say? i.e. src/modules/rlm_eap/types/rlm_eap_pwd/config.log It should be filled with logs from all of the attempts to compile the source.

3. The configuration of src/modules/rlm_unbound does not yet work:

...

Again, I am sure that openssl/crypto.h is in place and readable by the compiler.

The same comments apply as above.

4. This issue is about src/modules/rlm_wimax:

...

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.

The same comments apply here, too. Let us merge the three problems types/rlm_eap_pwd, src/modules/rlm_unbound and src/modules/rlm_wimax: All of the configuration scripts are somehow called by the main configuration script, and the two parameters for the OpenSSL directories are passed to each of the three "sub" configuration scripts. However, in contrast to the main configure script, none of the three knows the parameters for the OpenSSL directories: [rieke@archer freeradius-server-2014-07-27_21-23]$ grep -i openssl-.*-dir configure src/modules/rlm_eap/types/rlm_eap_pwd/configure src/modules/rlm_unbound/configure src/modules/rlm_wimax/configure configure: --with-openssl-lib-dir=DIR configure: --with-openssl-include-dir=DIR configure:# Check whether --with-openssl-lib-dir was given. configure:# Check whether --with-openssl-include-dir was given. configure:as_fn_error $? "failed linking to libssl. Use --with-openssl-lib-dir=<path>, or --with-openssl=no (builds without OpenSSL) configure:as_fn_error $? "failed linking to libcrypto. Use --with-openssl-lib-dir=<path>, or --with-openssl=no (builds without OpenSSL) configure:as_fn_error $? "failed locating OpenSSL headers. Use --with-openssl-include-dir=<path>, or --with-openssl=no (builds without OpenSSL) For that reason, the config.log files show that the parameters are passed correctly to the configure "sub" script, but since these parameters are ignored the compiler is not able to find the header files. The following log lines are from rlm_eap_pwd, but the others have the same problem: configure:2758: checking for openssl/ec.h configure:2773: gcc -c -g -O2 conftest.c >&5 conftest.c:10:30: error: openssl/ec.h: No such file or directory ... configure:2850: checking for openssl/ec.h in /usr/local/include/ configure:2865: gcc -c -g -O2 -isystem /usr/local/include/ conftest.c >&5 conftest.c:10:30: error: openssl/ec.h: No such file or directory ... configure:2850: checking for openssl/ec.h in /opt/include/ configure:2865: gcc -c -g -O2 -isystem /opt/include/ conftest.c >&5 conftest.c:10:30: error: openssl/ec.h: No such file or directory I am quite sure that FRS compiles without problems on many other systems, but in those cases, the compiler takes the OpenSSL header files from the system and not from the specified directories - on my machine, I have removed the openssl-devel RPM package (CentOS), and thus, I get that failure. However, maybe the failure is better than a wrong header file...

When I pass 'CPPFLAGS="-I /opt/openssl/include"' to the main configure script, the problems are solved for the headers - as an example, ec.h is found immediately. However, FRS still uses the system libraries :-(

Please let me know if I can do anything to help you solving the issue, Andreas
