Hi guys,
I'm in the process of upgrading from 2.2 to 2.4, and trying to migrate custom modules however running into a weird problem when regenerating the configure.
So in modules/ssl, it has the config.m4 file that add its checks for mod_ssl. Previously I add my own ssl related changes in there so that it will expand the macros when running autoreconf... but with 2.4 it doesn't seems to expand them properly anymore.
Even if I run the vanilla config.m4, it still prints out some weird character.
So this is the vanilla config.m4, the section that I am interested in...
| Code: |
dnl # hook module into the Autoconf mechanism (--enable-ssl option)
APACHE_MODULE(ssl, [SSL/TLS support (mod_ssl)], $ssl_objs, , most, [
APACHE_CHECK_OPENSSL
if test "$ac_cv_openssl" = "yes" ; then
if test "x$enable_ssl" = "xshared"; then
# The only symbol which needs to be exported is the module
# structure, so ask libtool to hide everything else:
APR_ADDTO(MOD_SSL_LDADD, [-export-symbols-regex ssl_module])
fi
else
enable_ssl=no
fi
// I need to add my stuff here
// AC_SUBST(HELLOWORLD_CFLAGS)
// AC_SUBST(HELLOWORLD_LIBS)
])
|
However, running autoreconf is giving me this, with a dangling colon...
| Code: |
done
if test $apr_addto_duplicate = "0"; then
test "x$silent" != "xyes" && echo " adding \"$i\" to MOD_SSL_LDADD"
MOD_SSL_LDADD="$MOD_SSL_LDADD $i"
fi
done
fi
fi
else
enable_ssl=no
fi
:
|
So firstly, I'd like to know where the heck the dangling colon is coming from...
Secondly, did they change the macros? the AC_SUBST won't expand... |

if I remember correctly the compiler flags are in modules/ssl/modules.mk
but that file will be rewritten bei the configure script. The configure script will read the env variables CC, CFLAGS, CPP, CPPFLAGS and LDFLAGS
that is why I set my custom SSL build directory to the LDFLAGS flag. See
| Code: |
./buildconf
export LDFLAGS="-Wl,-rpath,/opt/openssl/lib"
./configure --prefix=/opt/apache2 --enable-pie --enable-mods-shared=all --enable-so --disable-include --enable-lua --enable-deflate --enable-headers --enable-expires --enable-http2 --with-nghttp2=/opt/nghttp2 --enable-ssl=shared --with-ssl=/opt/openssl --with-openssl=/opt/openssl --with-crypto --enable-module=ssl --enable-mpms-shared=all --with-mpm=event --enable-rewrite --with-z=${HOME}/apache24/httpd-${HTTPD_VERSION}/srclib/zlib --enable-fcgid --with-included-apr
make

Yeah I could do that, but the feature can be enable by switch, so I don't really want to hardcode the flags there.
| Code: |
AC_ARG_WITH(helloworld,
APACHE_HELP_STRING([--with-helloworld],[with helloworld support]))
if test "$with_helloworld" != "no"; then
PKG_CHECK_MODULES([HELLOWORLD], [helloworld-blah])
if test -n "$HELLOWORLD_CFLAGS$HELLOWORLD_LIBS"; then
AC_DEFINE(HAVE_HELLOWORLD, 1, [we have helloworld])
fi
AC_SUBST(HELLOWORLD_CFLAGS)
AC_SUBST(HELLOWORLD_LIBS)
fi
|
The thing is, it expanded the AC_DEFINE correctly, it just won't expand the AC_SUBST... also that dangling colon is still a mystery..
Edit: Also, another thing is that, it doesn't understand the PKG_CHECK_MODULES macro after it generated the configure... |
