OpenBSD: proxychains crashes with 'Abort trap (core dumped)' error on launch about proxychains-ng

[rofl0r]

did it work earlier when we fixed the build?

[sysfu]

No, this is the first opportunity I've had to test it since you fixed the compilation problem.

[rofl0r]

unfortunately your backtrace is worthless without symbol names. see if you can provide a better backtrace with full debug info activated (proxychains is by default built with debug info so i'm unclear why yours is missing)

[sysfu]

I'm having a hard time finding information about how or where to load the symbol names for OpenBSD. If you have any suggestions please let me know.

[rofl0r]

this seems to be due to a bug in openbsd's dynlinker.
seems we need to wait for a openbsd crack who knows how to get libc + dynlinker with debug symbols to track down the issue (due to lack of a pre-installed openbsd developer image for usage in qemu i went through the installer process, which left me with a semi-unusable system with a 1970's userland - no git, no wget, no curl, etc which took me about 2 hrs of investigation, manual download of tools (with "ftp") just to reproduce the issue, but nowhere near getting a proper backtrace)

try if modifying Makefile to

 $(LDSO_PATHNAME): $(LOBJS)
- $(CC) -shared -lpthread $(LIBDL) $(LDFLAGS) $(LD_SET_SONAME)$(LDSO_PATHNAME) -o $@ $(LOBJS)
+ $(CC) $(CFLAGS) -lsocket -lnsl -shared -lpthread $(LIBDL) $(LDFLAGS) $(LD_SET_SONAME)$(LDSO_PATHNAME) -o $@ $(LOBJS)

fixes it (addition of -lsocket -lnsl )

[rofl0r]

nope, those libraries are apparently not existing on OpenBSD

[sysfu]

Yes, fails to build with Makefile mod

/usr/bin/ld: cannot find -lsocket
collect2: ld returned 1 exit status
Makefile:85: recipe for target 'libproxychains4.so' failed
gmake: *** [libproxychains4.so] Error 1

Also, if you need an OpenBSD 5.7 system to bang on, send me your pub SSH key and I'll reply with access info. XMPP/OTR contact info is in my profile.

@sysfu This issue needs to be closed out since OpenBSD does not even compile with ProxyChains-ng anymore AND the release 5.7 is outdated, new release is 6.7.
