Segmentation fault: 11 on Mac OS X 10.12.3

[demiangomez]

I've successfully compiled in OS X 10.12.3 (Sierra) using -lSystem.B as suggested in this issue: https://github.com/tomojitakasu/RTKLIB/issues/137. However, when I try to run rnx2rtkp I get "Segmentation fault: 11". I also tried removing -lrt (without adding -lSystem.B) and I get the same error. In Linux (Ubuntu 14.04) it works fine (without changing -lrt). I can't see anything wrong with the compilation, other than just some warnings (gcc seems not to know about -Wno-unused-but-set-variable):

Any ideas of what might be going on?
Thank you,

hi, check this https://github.com/blaines/RTKLIB/blob/master/src/rtkcmn.c @blaines he may find some way to fix Segmentation fault

hi, I'm trying to run rnx2rtkp on mac OS X (10.12.4) and after awhile I was finally able to compile the app (-lSystem.B might have helped). Now when a run rnx2rtkp I get the same "Segmentation fault: 11". Does anyone have an idea what could it be?

thanks

Does anyone have an idea what could it be?

Probably yet another uninitialized variable / pointer / pointer array / string. RTKLIB is full of them.

Check out the fork in https://github.com/rtklibexplorer/RTKLIB/tree/demo5 It compiles cleanly.
