Bug #71265 Library name mismatch for PCRE on Ubuntu

Description:
ERROR 1126 (HY000) at line 33: Can't open shared library 'libmy_json_udf.so' (errno: 2 libpcreposix.so.0: cannot open shared object file: No such file or directory)
ERROR 1126 (HY000) at line 33: Can't open shared library 'libmy_json_udf.so' (errno: 0 libpcre.so.0: cannot open shared object file: No such file or directory)

How to repeat:
Download pre-compiled UDFs and try to install them.

Some extra info (with the symlink work-around in place!)

Suggested fix:
A quick work-around is to symlink the libraries

root:/usr/lib/x86_64-linux-gnu# ln -s libpcreposix.so libpcreposix.so.0
root:/usr/lib/x86_64-linux-gnu# ln -s libpcre.so libpcre.so.0

An option would be to ship a different .so file for Ubuntu or make sure the UDF uses libpcre.so instead libpcre.so.0

Thank you for the report.

Another workaround is to use cmake option WITH_PCRE=bundled

Posted by developer:
 
Fixed in versions 0.2.2 and 0.3.1

Version 0.3.1 contains incompatible change:

Now default value for compile option WITH_PCRE is bundled independent from the
platform (Bug #71265/18081332 Library name mismatch for PCRE on Ubuntu)

For version 0.2.2 only binaries built with option WITH_PCRE=bundled
