I was exposing MY situation, not in general. To make everything work in my
case, I have to start from a working state.

Here again, it’s MY case, I wasn’t meaning in general.

I have to admit that I need to go forward on my project, but I also want to
sort this out. I’ve tried many combination, without success. I could blame
Qt/Qt-Creator but the errors were related to sqlite.

I’ve even just tried to compile “hello” example by command line, using
clang-c++:

Compiled with c++-4.9, no error.

Maybe it’s related to my system... The thing is that I’ve completely
reinstalled my system on 10.9 (Maverick), the only system “things” I’ve
reinstalled is Xcode, Qt (isolated) and homebrew (isolated but touches
$PATH).
I don’t know what could I check more...

While writing this email, something strange happened, the lib compiled with
GCC and my app with clang, no more runtime errors... I don't understand,
same code, same environment and no more libc++/glibc. So I got 2 ideas to
check to determine where it could come from:
1- Make a clean partition, install nothing on it but the required lib (gcc,
xcode, odb, libodb, ...) then try and log environment combinations (because
the libc++abi error shouldn't have disappeared)
2- Try with another db driver, because so far I've only tried libodb-sqlite.

Then I'll be back to you to keep you updated. Yosemite (10.10) is now final
and released, i'll also check on this system.

Thanks for your help.
