Hello, I'm trying to compile httpd-2.4.1 with mod_session_crypto, but the configure step errors out: #./configure --enable-session-crypto --with-included-apr ... snip snip .... configure: WARNING: Your APR does not include SSL/EVP support. configure: error: mod_session_crypto cannot be enabled I have apr-1.4.6 and apr-util-1.4.1 on CentOS 5.7. I have also tried building on an older version of Ubuntu with similar results. Both machines had Apache 2.2 before, but I don't know if that has anything to do with it. My srclib/apr-util/config.log shows what I suspect might be a clue to the problem: ... snip snip ... configure:36305: checking style of crypt_r configure:36322: gcc -c -g -O2 -pthread -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE conftest.c >&5 conftest.c: In function 'main': conftest.c:29: error: 'CRYPTD' undeclared (first use in this function) conftest.c:29: error: (Each undeclared identifier is reported only once conftest.c:29: error: for each function it appears in.) conftest.c:29: error: expected ';' before 'buffer' conftest.c:30: error: 'buffer' undeclared (first use in this function) configure:36322: $? = 1 configure: failed program was: | /* confdefs.h */ | #define PACKAGE_NAME "" | #define PACKAGE_TARNAME "" | #define PACKAGE_VERSION "" | #define PACKAGE_STRING "" | #define PACKAGE_BUGREPORT "" | #define PACKAGE_URL "" | #define STDC_HEADERS 1 | #define HAVE_SYS_TYPES_H 1 | #define HAVE_SYS_STAT_H 1 | #define HAVE_STDLIB_H 1 | #define HAVE_STRING_H 1 | #define HAVE_MEMORY_H 1 | #define HAVE_STRINGS_H 1 | #define HAVE_INTTYPES_H 1 | #define HAVE_STDINT_H 1 | #define HAVE_UNISTD_H 1 | #define HAVE_ICONV_H 1 | #define HAVE_LANGINFO_H 1 | #define HAVE_NL_LANGINFO 1 | #define HAVE_CODESET 1 | #define APU_DSO_BUILD 1 | #define HAVE_CRYPT_R 1 | /* end confdefs.h. */ | #include <crypt.h> | int | main () | { | CRYPTD buffer; | crypt_r("passwd", "hash", &buffer); | ; | return 0; | } Any ideas?
