QUESTION: (P0) coredump when running FlxStat test program in Linux

[jcheng]

Hi,

We tried to compile our FlxStat test program in Linux. When we run it, linking with the .so libraries, we get a core dump at the first call of the FlxStat API. Here is the stack trace:

Not sure if this is a compatibility issue? Any suggestions? BTW the same program runs in Windows without a problem.

Thanks,

Hmm, what are you linking with? You should only link with libFlxStat.so (-lFlxStat).

[jcheng]

I was linking with both libFlxStat and libFlxStatImpl, maybe that was the problem. I linked with libFlxStatImpl because it seems to contain the lc_* commands which I couldn't really find elsewhere.

Thanks,
Johnson

Did you solve this? otherwise give me a call and let's discuss.

Thanks

When i stopped linking with the FlxStatImpl library, the problem seems to be solved. However I had to remove the lc_* functions because they became unresolved at compile time, and therefore couldn't use our original test code. I think maybe I am not linking some other FLEX library that provides these. Do you have any idea what it might be?

Thanks,
Johnson

This issue is resolved. We are able to properly build with both libraries.
