The function sv2int_str is defined in kamailio/src/modules/app_perl/kamailioxs.xs as inline. Which is why it does not show up in the .o or, therefor, the .so. The question is what expects it as a symbol? Removing inline from its definition may be a quick workaround. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6 -- You are receiving this because you commented.

I can confirm that CC_OPT=-O2 solves the problem. I've added this to our installer, so it solves the problem for us. It would still be good to fix this for others. -- You are receiving this because you commented.

DM> If the function is not used in the same object (source file) only, DM> then inline should be removed, It is only used in the .xs file where it is defined. Without optimization gcc (at least gcc 5) leaves it in the .o file as an undefined symbol. I just duplicated what kamailio master does to make(1) kamailioxs.s, but with -S instead of -c. The four places where sv2int_str() is called show up as: call sv2int_str@PLT With -O2 or -O1 it gets inlined. So it seems that w/o optimization gcc5 fails to inline the function at its call sites, but also leaves it out because it was defined as inline. Gcc-4.8, OTOH, compiles it as a non-inlined function called run w/o optimization. So this is a gcc bug which kamailio can work around by optimizing. I see in Makefile.defs that CC_OPT defaults to -O3 when using clang. And before that it is ?='ed to -O9. But that -O9 didn't make it into the gcc calls when I tried compiling with Q=0. To test, make kama however you normally do, then: cd src/modules/app_perl rm kamailioxs.o make kamailioxs.o Q=0 copy the resulting cc line, replacing -c with -S and kamailioxs.o with kamailioxs.s and search for sv2int_str in that kamailioxs.s. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6 -- You are receiving this because you commented.
