Re: Snort 2.9.6 and DPX 1.6 test error: undefined libversion

Are you sure Snort isn't trying to load the old version?

If you are on Linux, what does this output?

    nm lib/snort_dynamicpreprocessor/libdpx.so | grep LibVersion

If you see something like the following, libdpx.so is not the problem:

    0000000000001485 T LibVersion

Subject: [Snort-devel] Snort 2.9.6 and DPX 1.6 test error: undefined libversion

I'm gonna create a dynamic preprocessor for Snort 2.9.6 using DPX 1.6. I followed the README in DPX 1.6, compiled Snort 
and build the sample prep (dpx) without error. But when I tested this, Snort failed to load the prep. It raised this 
error:

    Loading all dynamic preprocessor libs from lib/snort_dynamicpreprocessor...

    Loading dynamic preprocessor library lib/snort_dynamicpreprocessor/libdpx.so... ERROR: Failed to find LibVersion() 
function in lib/snort_dynamicpreprocessor/libdpx.so: lib/snort_dynamicpreprocessor/libdpx.so: undefined symbol: 
LibVersion

    Fatal Error, Quitting..

Is there any idea why and how to solve this?
