Hi,

=20

I'm using Fedora Core 4 with MySQL 4.1.16. I compiled and run resetdb =
successfully. =20

It created the sample database. Then I compiled simple1.cpp, but when I =
run it, it dumps this:

I have solved this problem by compiling
http://tangentsoft.net/mysql++/relea...+-2.0.7.tar.gz in Fedora
Core 4. I did not use rpmbuild, just the ./configure then make.

I'm using Fedora Core 4 with MySQL 4.1.16. I used the mysql++ 2 rpm
suggested/implied in the online mysql++ document. I compiled and run
resetdb
successfully. It created the sample database. Then I compiled
simple1.cpp, but when I run it, it dumps this:

[root@localhost examples]# ./simple1

*** glibc detected *** ./simple1: free(): invalid pointer: 0x08947ab0 ***

So i used the mysql++ source and recompiled it in Fedora Core 4 with
GCC 4. Then I no longer have the invalid pointer error. Maybe the
rpm was built using GCC 3+ and will have issues under GCC 4.
