I am working on VSP. I build my plugin with no errors and put in the addons file with .vdf file. But the plugin doesnt work and give myplugin.so: undefined symbol: KeyValuesSystem from server console.
Normally my plugin worked fine. I add code to use KeyValues class then build successfully but doesnt load and give error above.
My another questions i cant link vstdlib.
MY Makefile like this:

LDFLAGS_PLG = -lm -ldl libtier0.so libvstdlib.so  $(LIB_DIR)/mathlib_i486.a $(LIB_DIR)/tier1_i486.a $(LIB_DIR)/tier2_i486.a $(LIB_DIR)/interfaces_i486.a

And ldd myplugin.so

    linux-gate.so.1 =>  (0xf7739000)
    libstdc++.so.6 => /usr/lib/i386-linux-gnu/libstdc++.so.6 (0xf7570000)

Thank you so much for your help.

Your problem is probably that you aren't linking vstdlib but you didn't give any information on what's going wrong with linking it.

You need to set LD_LIBRARY_PATH (like srcds_run does) before running ldd to get useful output.

I set LD_LIBRARY_PATH and ldd output like below:

    linux-gate.so.1 =>  (0xf77d2000)
    libstdc++.so.6 => /home/cemalege/csgoserver/bin/libstdc++.so.6 (0xf76d5000)
    libgcc_s.so.1 => /home/cemalege/csgoserver/bin/libgcc_s.so.1 (0xf76c0000)
    libdl.so.2 => /lib/i386-linux-gnu/libdl.so.2 (0xf769d000)
    libtier0.so => /home/cemalege/csgoserver/bin/libtier0.so (0xf764f000)
    libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf7499000)
    libm.so.6 => /lib/i386-linux-gnu/libm.so.6 (0xf7444000)
    /lib/ld-linux.so.2 (0x565f0000)
    libpthread.so.0 => /lib/i386-linux-gnu/libpthread.so.0 (0xf7427000)
