Please note that default in custombuild is still the old version PCRE 8.20. However DirectAdmin has now added a option in custombuild 1.2 and 2.0 to have the new PCRE 8.32 version, I have upgraded to PCRE 8.32 myself, and there was no problems.
Here is how you upgrade to PCRE 8.32:
Then set the value in the /usr/local/directadmin/custombuild/options.conf:
./build set new_pcre yes
Then continue like this:
./build php n
Please note that it is necessary to recompile exim, because exim binaries are linked against the old version. It is also needed to recompile php.
However, I don’t know if it is necessary to recompile anything else then exim and php? Do you know? If so, please share. Thanks.
