Fails to build on Slackware64 14.2

[zoot]

Hi there

I discovered a build bug when compiling under Slackware64 14.2

The build failed with:

g++ -g -O2 -Wall -fPIC -fsigned-char -g0 -O2 -Wno-unused-but-set-variable -Wno-unused-but-set-parameter -o ktserver ktserver.o myscript.o \
  -L. -L/pkg/kyototycoon-al/20170410/lib -L/usr/local/lib -L/usr/local/lib/lua -L/pkg/kyotocabinet-al/20170410/lib -L/pkg/lua/5.1.5/lib -Wl,-rpath-link,.:/usr/local/lib:.:/usr/local/lib::/usr/local/lib/lua:/pkg/kyotocabinet-al/20170410/lib:/pkg/lua/5.1.5/lib -Wl,--as-needed  -lkyototycoon -lkyotocabinet -llua
/usr/lib64/gcc/x86_64-slackware-linux/5.3.0/../../../../x86_64-slackware-linux/bin/ld: /pkg/lua/5.1.5/lib/liblua.a(loadlib.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'
/lib64/libdl.so.2: error adding symbols: DSO missing from command line
collect2: error: ld returned 1 exit status
Makefile:535: recipe for target 'ktserver' failed

So, searching the web for:

"liblua.a(loadlib.o): undefined reference to symbol 'dlclose@@GLIBC_2.2.5'"

... led me to this link

... which states:

-ldl where dlclose@@GLIBC_2.2.5 should be after -llua, where this symbol is used.

So I patched the Makefile as follows to correct the issue:

cd /path/to/kyoto/kyototycoon
sed -i 's/CMDLIBS =  -lkyotocabinet -llua/CMDLIBS =  -lkyotocabinet -llua -ldl/' Makefile

I can't reproduce this issue on macOS, Debian or CentOS, but I've commited a tentative fix (carlosefr@4d77ac4) that doesn't involve modifying files created during the build process. Can you try building from my fork[1] and see if it solves it?

Morning Carlos

I had the same reservations regarding patching the Makefile itself.

Yes, that resolves it, thank you.

Great. 👍
