Error: Symbol pa_log_level_meta not found

[hanselmandrew]

In my attempt to run a Valheim server with cross play enabled on an Ubuntu 22.04 ARM64 instance via Oracle Cloud, I'm hitting this error:

Dec 27 17:40:00 instance-20241226-2040 valheim_server.x86_64[17836]: Error: Symbol pa_log_level_meta not found, cannot apply R_X86_64_JUMP_SLOT @0x7fff06004fc0 (0x1140) in ./linux64/libpulse-mainloop-glib.so.0
Dec 27 17:40:00 instance-20241226-2040 valheim_server.x86_64[17836]: Error: relocating Plt symbols in elf libpulse-mainloop-glib.so.0

Trying to locate the exact library that has the hard link to the method:

ubuntu@instance-20241226-2040:/mnt/data/valheim/valheim_server/linux64$ nm -gCD libpulse-mainloop-glib.so.0 | grep "log_level"
                 U pa_log_level_meta
ubuntu@instance-20241226-2040:/mnt/data/valheim/valheim_server/linux64$ nm -gCD libpulse-simple.so.0 | grep "log_level"

                 U pa_log_level_meta
ubuntu@instance-20241226-2040:/mnt/data/valheim/valheim_server/linux64$ nm -gCD libpulse.so.0 | grep "log_level"

                 U pa_log_level_meta
ubuntu@instance-20241226-2040:/mnt/data/valheim/valheim_server/linux64$ nm -gCD libpulsecommon-15.99.so | grep "log_level"

00000000000385c0 T pa_log_level
0000000000030840 T pa_log_level_meta
00000000000385a0 T pa_log_levelv
000000000002fd20 T pa_log_levelv_meta

I see that the there are some references to the pa_log_level_meta method, but they are preprocessed away:

box64/src/wrapped/wrappedpulse.c

Lines 48 to 55 in e2d7cc5

	#if 0
	#ifdef NOALIGN
	typedef void (*vFipippV_t)(int, void*, int, void*, void*, va_list);
	#else
	typedef void (*vFipippV_t)(int, void*, int, void*, void*, void*);
	#endif
	GO(pa_log_level_meta, vFipippV_t)
	#endif

box64/src/wrapped/wrappedpulse.c

Lines 1470 to 1482 in e2d7cc5

	#if 0
	EXPORT void my_pa_log_level_meta(x64emu_t* emu, int level, void* file, int line, void* func, void* format, void* b, va_list V)
	{
	#ifndef NOALIGN
	// need to align on arm
	myStackAlign((const char*)format, b, emu->scratch);
	PREPARE_VALIST;
	return my->pa_log_level_meta(level, file, line, func, format, emu->scratch);
	#else
	return my->pa_log_level_meta(level, file, line, func, format, V);
	#endif
	}
	#endif

I spent a non-zero (but small) amount of time trying to fix this myself, but I am not familiar with this code base, so I didn't make it far.

• This block of code is 3 years old
• myStackAlign type signature seems to be slightly different now
• I think pa_log_level_meta also needs a GO/GOM somewhere else

Yeah, need to wrap this function. I'll check tomorow if I can wrap it.

I may have spoke too soon, I realized that I was running on v2.6, so I updated to v3.2 to make sure that wasn't an issue. That was causing the server boot to repeatedly crash. Just to be sure, I installed the entire pulselib-dev library, and reinstalled the server via steamcmd, and I'm not seeing the reported missing symbol error anymore. So this may be a non-issue.

Still having some crashes related to some mono watchdog timer, but that seems unrelated to this library.
