Description Gerhard Stein 2013-10-26 05:23:21 UTC 
I tried to link against the most recent stable SDL2 and got this problem:

As you see, I tried it in your test routines. Same thing happens when trying to compile another project with this lib.I'm using Arch Linux.
Comment 1 Gerhard Stein 2013-10-26 05:28:45 UTC 
Just tried SDL 2.0.0 and yeah, it doesn't have that problem.
Comment 2 Gabriel Jacobo 2013-10-30 14:00:20 UTC 
I just tried to reproduce with the 2.0.1 release, running both configure and configure --disable-libudev, and it works fine with either.

Can you provide more information to help debug this? config.log, SDL_config.h, which commands you are running to build and install both SDL and the tests?

Thanks!
Comment 3 Gerhard Stein 2013-10-30 14:06:12 UTC 
Just tried it again with:

./configure

and then:

make
sudo make install
cd test
make

everything worked with SDL 2.0.1.

Let me try to reproduce somehow. Maybe it was an issue with Arch and got somehow fixed. Sorry for bothering. I might close this issue...

Feel free to reopen if you find out there was actually a problem. Thanks for the report!
