SVN / Apache Issue undefined symbol: apr_crypto_block_cleanup

I am using AlmaLinux 8 with svn/apache.

When trying to start my httpd service I am given the following status message:

Aug 12 17:54:06 domain.tld httpd[495168]: httpd: Syntax error on line 132 of /etc/httpd/conf/httpd2.conf: Syntax error on line 1 of /etc/httpd/conf/extra/httpd-svn.conf: Cannot load /usr/lib/apache/mod_dav_svn.so into server: /usr/lib64/libsvn_subr-1.so.0: undefined symbol: apr_crypto_block_cleanup

In the past, simply moving /usr/lib64/libsvn_subr-1.so.0 to /usr/lib64/libsvn_subr-1.so.0-old fixed the error but on this occasion (having updated dnf) this is not the case.

Struggling because I have limited debugging opportunities so if anything at all can be provided to help debug that would suffice as an answer. the only output I can find suitable for me is below.

Currently svn is only served via svn hence I don't even have svn available at cli.

Please help!

Solution

  • Running the following fixed my problem:

    tar xvf subversion-1.14.3.tar.gz
cd subversion-1.14.3
wget https://www.sqlite.org/2015/sqlite-amalgamation-3081101.zip -O sqlite-amalgamation-3081101.zip
unzip sqlite-amalgamation-3081101.zip
mv sqlite-amalgamation-3081101 sqlite-amalgamation
./configure --prefix=/usr --with-apxs=/usr/sbin/apxs --with-apr=/usr/bin/apr-1-config --with-lz4=internal --with-utf8proc=internal
make -j4
mv subversion/mod_dav_svn/.libs/mod_dav_svn.so /usr/lib/apache/mod_dav_svn.so

    Thanks anyway, hope this helps someone (most likely me) in the future.
