Starting from: httpd 2.4.3 apr 1.4.6 apr-util 1.4.1 If I build apr 1.4.6 and install it I build apr-util 1.4.1 after configuring --with-crypto and install it. I then try to run ./configure --with-apr=/opt/apr-1.4.6 --with-apr-util=/opt/apr-util-1.4.1 --prefix=/opt/apache-httpd-2.4.3 --enable-session-crypto --with-crypto and I am rewarded with: configure: WARNING: Your APR does not include SSL/EVP support. To enable it: configure --with-crypto configure: error: mod_session_crypto cannot be enabled Now, 'apr' has no --with-crypto option in its ./configure. apr-util does, and I used it, and didn't get any errors, but its config.log has, buried in it: configure:36220: checking for library containing crypt configure:36251: gcc -o conftest -g -O2 -pthread -DLINUX=2 -D_REENTRANT -D_GNU_SOURCE conftest.c >&5 /tmp/ccIBnHnD.o: In function `main': /basis/treez/benson/http/apr-util-1.4.1/conftest.c:35: undefined reference to `crypt' collect2: ld returned 1 exit status I note that man 3 crypt says that you need _XOPEN_SOURCE to get it. Is this, to begin with, a bug in the httpd configure script that points at the wrong place for --with-crypto? Secondly, since I did, in fact, configure with --with-crypto, what have I got to do to make this work. All of this is on a centos 5 system --------------------------------------------------------------------- To unsubscribe, e-mail: users-unsubscribe@xxxxxxxxxxxxxxxx For additional commands, e-mail: users-help@xxxxxxxxxxxxxxxx
