Hi Rob,

I am trying to compile synchronet on Ubuntu (Bookworm), following https://wiki.synchro.net/install:nix. Both the git build method and the tarball method fail with this error msg:

Linking gcc.linux.x64.exe.release/sbbsecho
/usr/bin/ld: /opt/synchronet/src/sbbs3/../xpdev/gcc.linux.x64.lib.release/libxp dev.a(link_list.o): in function `listSemTryWaitBlock': link_list.c:(.text+0x21a): undefined reference to `sem_trywait_block' /usr/bin/ld: /opt/synchronet/src/sbbs3/../xpdev/gcc.linux.x64.lib.release/libxp dev.a(link_list.o): in function `listInit':
link_list.c:(.text+0x531): undefined reference to `pthread_mutex_initializer_np'
collect2: error: ld returned 1 exit status

I understand that the functions listSemTryWaitBlock() and pthread_mutex_initializer_np() are defined in threadwrap.c. I checked src/xpdev/gcc.linux.x64.obj.release and found that threadwrap.o is missing, i.e. it is not being compiled.

Kindly advise how to fix this issue, please.

Best,
Stefan

Usually if a compile fails, the first thing I do is run ./cleanall.sh
from the src directory.
You could also run make with the --trace option to see what's going on.
I suspect you're missing a library or something.

Thanks. I "cleaned" at least twice, i.e. deleted everything and started the compile process fresh.

It is not a compiler issue, it is an issue with the Makefile. The file threadwarp.c is not compiled. I don't see the threadwarp.o and threadwarp.a files, although I see all other .o and .a files created for "sbbsecho". Of course, the linker complains about missing functions from threadwarp.

I followed the install guide in the wiki, i.e. I have all prerequisites, all installed. Not sure whether any additional library should be missing. The linker does not complain about a missing library.

I will use "--trace", thanks.

Maybe you got a build failure in xpdev first? Try running 'make' (or 'make RELEASE=1') in the src/xpdev directory and see if you get errors.

Update: After the make in the xpdev folder, sbbsecho could be linked and the main build command continued. Not sure why...
