I am compiling the sample_mm plugin for CS:GO included with the metamod source (1.11.0-dev) on a 64 bit linux machine using gcc-4.7.

The plugin itself compiles fine, but when I try to load the plugin using meta load sample I get the error:

Failed to load plugin addons/sample_mm (addons/sample_mm.so: undefined symbol: _ZdlPv).

Any information or advice regarding this? I am pretty new to linux compilation in general as I come from a mostly Java background so any help would be appreciated.

Thanks!

PHP Code:

[michael:~/Desktop/MMPlugin/sample_mm]$ make ENGINE=csgo
if [ "true" = "false" ]; then \
        echo "You must supply one of the following values for ENGINE:"; \
        echo "csgo, left4dead2, left4dead, css, orangeboxvalve, orangebox, or original"; \
        exit 1; \

Yes I saw this but I am very hesitant to add that compiler flag when the wiki says:

There are a few flags you should generally not add, ever: -lstdc++ (same as using g++) - Even if you use the exact same compiler build as Valve, linking against the libstdc++ will be painful. Not all Linux distributions use the same version, and in general ABI compatibility on this library is frequently broken. You will find that users report load failures or even crashes, and the problem may be very difficult to trace. As such, you should avoid using exceptions or any part of the Standard Template Library (STL). Valve provides many abstractions that should suffice, and SourceHook provides some as well.

Due to some changes in CS:GO, that is now necessary (unless you can find a better workaround).

Ahh, thanks for that psychonic, just another csgo quirk.
