luke: fatal: required symbol 'yaml_document_initialize' not found in any of libc, libyaml

I have installed luarocks for a customised lua version based on 5.1. and now trying to install specl which depends on lyaml. and getting this error. I thought this was fixed in latest version.

This isn't an issue in lua version 5.1.5 but not working with customized 5.1.2

please paste the entire output from running: /<>j/bin/lua build-aux/luke package="lyaml" version="6.2.5" PREFIX="/opt/luarocks5_1/lib/luarocks/rocks-5.1/lyaml/6.2.5-1" CFLAGS="-O2 -fPIC" LIBFLAG="-shared" LIB_EXTENSION="so" OBJ_EXTENSION="o" LUA="/opt/<>j/bin/lua" LUA_DIR="/opt/luarocks5_1/lib/luarocks/rocks-5.1/lyaml/6.2.5-1/lua" LUA_INCDIR="/opt/<>/include/lua" YAML_DIR="/usr" YAML_INCDIR="/usr/include" YAML_LIBDIR="/usr/lib/x86_64-linux-gnu" --verbose --debug

The above log obtained when trying to install specl with a fixed version of lua interpreter 5.1.2.

Later, successfully installed specl by replacing 5.1.2 with 5.1.5 interpreter. then switched back to 5.1.2,but not sure about the risk of using older version of lua with latest specl for a project

Also there is no "--debug" option for luarocks, hence only verbose output log attached.

But the command I pasted is an invocation of build-aux/luke from inside an lyaml rock using your Lua interpreter and with the addition of —debug and —verbose flags... nothing to do with luarocks. You will need to fetch and unpack the lyaml rock or download the matching release tarball from github first (e.g. https://github.com/gvvaughan/lyaml/archive/v6.2.5.tar.gz ), and from the top level directory of that run the command I pasted above to get enough debug output to help me understand why you’re experiencing an error :-)

Huh, interesting... seems like your compiler is sad about the lack of main in the test program. I need to tweak the link test source generator... please give me a few days to find time, and thanks for the report!
