Bug 2686 – Mysql++ api segfaults with the gentoo mysql database

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Charles Kerr 2002-05-12 20:11:08 UTC]

If one installs mysql from the www.mysql.org/com website, and takes the 
standard configure, when one adds mysql++ (the programming api), all works.

but when mysql++ is installed with the gentoo mysql, any attempt to access the 
mysql++ library results in a segfault.

it would be nice if you included extra information.

this is an example use that will sefgault

If built on a maching not using the ebuild version of msyql, the mysql++ api
doesn't segfault.  but with gentoo, this program will segfault.

Makefile for the tst file

This is the make file for the test file attached earlier.

Essentially, I can not get the mysql++ API to work successfully on gentoo with
the msyql ebuild.

The following patch will fix this segfault (posted at 
http://marc.theaimsgroup.com/?l=mysql-bugs&m=101553136709356&w=2):

Any chance that getting into the mysql.ebuild ?

looks like your patch is now in mysql-3.23.50.  i've added
a new ebuild that should fix this.
