I've tested it with CPPFLAGS too without success (before sending the previous email). checking openssl/ssl.h usability... yes checking openssl/ssl.h presence... no configure: WARNING: openssl/ssl.h: accepted by the compiler, rejected by the preprocessor! configure: WARNING: openssl/ssl.h: proceeding with the preprocessor's result checking for openssl/ssl.h... no config.log: =========== ## ---------------- ## ## Cache variables. ## ## ---------------- ## ac_cv_build=i686-pc-linux-gnu ac_cv_build_alias=i686-pc-linux-gnu ac_cv_c_compiler_gnu=yes ac_cv_env_CC_set=set ac_cv_env_CC_value=gcc ac_cv_env_CFLAGS_set=set ac_cv_env_CFLAGS_value=$'-O2 -g -I/usr/local/ssl/include' ac_cv_env_CPPFLAGS_set=set ac_cv_env_CPPFLAGS_value=$'-O2 -g -I/usr/local/ssl/include' Taking a closer look to configure output I see: checking for egrep... grep -E configure: using CPPFLAGS=-D_GNU_SOURCE configure: using LDFLAGS=-L/usr/local/ssl/lib checking for gawk... gawk It seems that the problem is in src/template/linux: $ cat src/template/linux # Force _GNU_SOURCE on; plperl is broken with Perl 5.8.0 otherwise CPPFLAGS="-D_GNU_SOURCE" which is beeing sourced by configure.in.
