Sorry for the late reply (vacation…).

Had a chance to check back and continue. Your new patch works great! Not sure why my attempt at the same thing failed, probably cut out too much (like the argv[0] bit). This is awesome, I can use mysqlcc again! Thanks! Hi! Had a chance to check back and continue. Your new patch works great!

I need to clean up some things to write a decent patch, so check back here for more news :) OK, did some more checking and managed to get mysqlcc to work with mysql 5.5.

This mysql 5.5 <a href="http://bugs.mysql.com/bug.php?id=62394" rel="nofollow">bug report</a> explains that these functions were actually not official in the first place. Anyway, I managed to get them back by editing the libmysql/CMakeLists.txt and rebuilding mysql 5.5. After that, mysqlcc built without problems, but - as you already experienced as well - immediately segfaults. If there is a "quick fix", I could not find it. I guess that too much has changed... I even tried version 1.0.1 of mysqlcc, but it had the same effect - it just did not need my patch any longer. Maybe the mysqlcc author will eventually fix this, when mysql 5.5 becomes more popular, but I wouldn't hold my breath :)

I’m extremely busy with job-related things at the moment, but I’ll take a look at this as soon as I can find some spare time!

I commented out all these functions in main.cpp (they just check cmd line args, which I don't use) but the resulting binary immediately segfaults in /usr/lib/mysql/libmysqlclient.so.18. Perhaps too much changed in the API? Or maybe there is a quick fix? Cheers, and thanks for the great tips: saved my bacon 1 year ago.

I was just researching MySQL with C client library for the first time and when the example code I had found through up an error about gptr I was at a loss. This post cracked it and it taught me an important lesson about how to investigate errors in C and where to find fixes. Thanks so much for this. =) Hey thanks for this.I was just researching MySQL with C client library for the first time and when the example code I had found through up an error about gptr I was at a loss.
