I am trying to replace manually a library for freeradius.
On a one hand I installed freeradius with an apt-get install. There was a library "" (let's call it the lib(apt)).
On the other hand I used the sources (from apt-get source) to modify the library "" (let's call it the lib(src)). The i compiled the sources (./configure, make) to retrieve this modified lib(src). (The lib works fine when i test it).

When I try to manually replace lib(apt) by lib(src) the freeradius segfaults during the call of that library.
So it seems that the libraries are not compatible.

Could it be because of compilation issues? (precompiled version versus local compilation)
Any ideas?

I wonder if some build option in the package install is missing in the source-built version – Journeyman Geek Apr 15 '13 at 9:09
Might be something like that, yes. Is there a way to know which build options were used for the precompiled version? – ycouble Apr 15 '13 at 9:13
I have no clue, would be an interesting thing to ask though! – Journeyman Geek Apr 15 '13 at 13:58
Thanks anyway :) – ycouble Apr 15 '13 at 17:08

I'm guessing that some build option that was used in the package install was missing in the source-built version you're using (assuming the changes to your code didn't cause it -this SF question may be a good start troubleshooting that). Apparently you can use auto-apt to pull in any dependancies as you're installing it but there's apparently no obvious tool to retrive what build options the original compilation used.
