iioflow commented 11 years ago

with artfwo's help on irc, it looks like this (and several other related errors) stem the use of "-Werror" in the wscript's CFLAGS. once "-Werror" is deleted, the build proceeded as normal, albeit with several other warnings about uninitialized variables.

however, rove now completely fails to run! either it's erroring out (with "segmentation fault" on loading a set) because of its own issues, or libmonome is at fault. a bit of gdb and backtrace results in this:

Program received signal SIGSEGV, Segmentation fault. 0x00007ffff76c5300 in monome_open () from /usr/lib64/libmonome.so.1 (gdb) bt

man.

can you recompile with debug symbols (CFLAGS=-ggdb) and reproduce the crash? it might be related to some of nedko's libmonome changes.

sorry for the slow reply, i'm busy as hell these days.

improved rove GDB output, with debugging symbols is below. note that i can't compile/install libmonome at the moment, because something changed in its codebase in the last 18 months such that it poisons the env ld.so cache -- maybe it doesn't use, or has a badly formatted, .pc file or something. so i'm stuck on my existing old libmonome for the foreseeable future. makes diagnosis a little harder, i know. my old unmodified libmonome fork should still work and not result in sandbox access violations at install/env-update time.

yeah the crash is happening in libmonome so without debug symbols there's not much we can do.

libmonome doesn't have a pkgconfig file. how does this poison your ld.so cache? (i'm not sure how it works on gentoo)

iioflow commented 11 years ago

i'll have to dig up some docs on gentoo's env variables and .pc files and expected locations of stuff, but in the mean time, i manually compiled libmonome via ./waf and debug. here's what i got:
