When I build apache 2.4.25, I build pcre, apr and apr util 1.5.2 without issue. When httpd builds it complains "Your APR does not include SSL/EVP support. To enable it: configure --with-crypto." The terminal output is below. And here is the linked httpd as reported by ldd. I dont see anything related to ssl, --with-crypto is not recognized by 'configure' either. Apache 2.2.32 seems to get it right, but I dont know how to get 2.4.25 to do it. Here are the config args I use... configure --prefix="$TARGET" --with-apr=$TARGET --with-apr-util=$TARGET --with-pcre=$TARGET --with-mpm=worker --enable-ssl=shared --enable-ssl --with-ssl=/usr/lib64 --enable-proxy --enable-proxy-connect --enable-proxy-ftp --enable-proxy-http --enable-headers --enable-expires > configureoutput.out linux-vdso.so.1 => (0x00007ffe40594000) libpcre.so.1 => /apps/apache/apache-httpd.2.4.25/lib/libpcre.so.1 (0x00007fb19f916000) libaprutil-1.so.0 => /apps/apache/apache-httpd.2.4.25/lib/libaprutil-1.so.0 (0x00007fb19f6f0000) libexpat.so.0 => /apps/apache/apache-httpd.2.4.25/lib/libexpat.so.0 (0x00007fb19f4c9000) libapr-1.so.0 => /apps/apache/apache-httpd.2.4.25/lib/libapr-1.so.0 (0x00007fb19f296000) librt.so.1 => /lib64/librt.so.1 (0x000000359ea00000) libcrypt.so.1 => /lib64/libcrypt.so.1 (0x00000035a4600000) libpthread.so.0 => /lib64/libpthread.so.0 (0x000000359e600000) libc.so.6 => /lib64/libc.so.6 (0x000000359de00000) /lib64/ld-linux-x86-64.so.2 (0x000000359da00000) libfreebl3.so => /lib64/libfreebl3.so (0x00000035a4e00000) libdl.so.2 => /lib64/libdl.so.2 (0x000000359e200000) Checking pcre pkg building pcre pkg for /apps/apache/apache-httpd.2.4.25 libtool: warning: relinking 'libpcreposix.la' Checking apr building apr for /apps/apache/apache-httpd.2.4.25 rm: cannot remove `conftest*': No such file or directory rm: cannot remove `conftest*': No such file or directory rm: cannot remove `libtoolT': No such file or directory mkdir /apps/apache/apache-httpd.2.4.25/build-1 mkdir /apps/apache/apache-httpd.2.4.25/include/apr-1 Checking apr-util building apr-util for /apps/apache/apache-httpd.2.4.25 configure: error: unrecognized option: `--with=-crypto' Try `./configure --help' for more information libtool: install: warning: relinking `libaprutil-1.la' building http for /apps/apache/apache-httpd.2.4.25 configure: WARNING: apr/apr-util is compiled without ldap support configure: WARNING: apr/apr-util is compiled without ldap support configure: WARNING: Your APR does not include SSL/EVP support.
