How to solve nchat libwmchat library linking error?

Recently I updated Go library (latest 1.21.1) on my arm64 linux system and now I have a linking error with libwmchat.so library.
This is the output:

"[100%] Linking CXX shared library ../libwmchat.so
/usr/bin/ld: go/libcgowm.so(go.o): relocation R_AARCH64_ADR_PREL_PG_HI21 against symbol crosscall2' which may bind externally can not be used when making a shared object; recompile with -fPIC /usr/bin/ld: DWARF error: line info data is bigger (0x37080637) than the space remaining in the section (0xe0e72) /usr/bin/ld: DWARF error: line info data is bigger (0x6370683) than the space remaining in the section (0xdf216) /usr/bin/ld: DWARF error: line info data is bigger (0x37063806) than the space remaining in the section (0xda650) /usr/bin/ld: DWARF error: line info data is bigger (0x56c00209) than the space remaining in the section (0xbe7b4) /usr/bin/ld: DWARF error: unhandled .debug_line version 0 /usr/bin/ld: DWARF error: line info data is bigger (0x2f646c69) than the space remaining in the section (0x4f33a) /usr/bin/ld: DWARF error: line info data is bigger (0x6d2f6372) than the space remaining in the section (0x369bc) /usr/bin/ld: DWARF error: line info data is bigger (0xb400de03) than the space remaining in the section (0x2f77e) go/libcgowm.so(go.o): in function runtime/cgo.set_crosscall2.abi0':

make[1]: *** [CMakeFiles/Makefile2:280: lib/wmchat/CMakeFiles/wmchat.dir/all] Error 2
make: *** [Makefile:136: all] Error 2"

I checked the -fPIC option presence in compile settings and it seems all ok.
Has anyone else detected this issue? Can you help me to solve it?

Hi @ferrodvd - I suspect this is a golang bug - see golang/go#62556 - perhaps you can try to switch back to an older go version until it's been fixed.

ok, thank you very much for your suggestion.

I downgraded golang to 1.20.9 and now the library gets compiled and linked correctly. Thanks again
