about compile linux extension problem

K.K.Lv · **Author**

Please move to the correct section if I put a incorrect section

I'm new on linux, so try to compile a extension on Ubuntu, but I confuse some problems
also I have read this doc http://wiki.alliedmods.net/building_sourcemod
I think I just don't know how to make file.
so I put the problem here, hope some one can tell me how to make it correctly.

1.when I compile the project with the default settings, the error is:

Code:

CDetour/detours.cpp: In member function ‘bool CDetour::CreateDetour()’:
CDetour/detours.cpp:120:25: error: array subscript is above array bounds [-Werror=array-bounds]
   detour_restore.patch[i] = ((unsigned char *)detour_address)[i];

2.so I try to remove the "-Werror" arg, and then can be compiled.but when the server started. it tell me this message:

Code:

L 12/01/2014 - 01:34:04: [SM] Unable to load extension "dropreason.ext": /home/administrator/Desktop/csgo/csgo/addons/sourcemod/extensions/dropreason.ext.so: undefined symbol: __dynamic_cast

this is my makefile

set up the AMBuilder file for your extension

psychonic · 12-01-2014 , 11:50 Re: about compile linux extension problem

For CS:GO on linux, as of a few months ago, you now need to link stdlibc++ (-lstdc++ or use g++/clang++ instead of gcc/clang).

Powerlord · 12-01-2014 , 17:02 Re: about compile linux extension problem

To add to what psychonic and WildCard65 said... the sourcemod-sampleext stuff in my repo was written WAY back when SM 1.6 was still in early development. It really needs an update, particularly the AMBuild stuff (which is AMBuild 1.x)

K.K.Lv · 12-01-2014 , 22:06 Re: about compile linux extension problem

thanks for your replies, and I have started to learn how to write a ambuild script.
@Powerlord by the way, I think it will be better that update you sample script when you are free ;), it will be nice for that guy who are the new on ambuild .

I still got the problem when I try to compile the mmsource and the sourcemod with local,
also the source of the mmsource and sourcemod are download from github
mmsource:https://github.com/alliedmodders/met...-1.10.4.tar.gz
sourcemod:https://github.com/alliedmodders/sou...d-1.6.3.tar.gz

did I have to remove "-Werror" arg ?

compile the debug version is success. but the release version is failed !
my command line is

Code:

python ../configure.py -s csgo --enable-optimize
ambuild

anything did I lose ?

psychonic · 12-04-2014 , 07:36 Re: about compile linux extension problem

We use Clang to compile the official builds. If you want to do a manual build with GCC, it looks like you need to add -Wno-unused-result. I'd be happy to review a pull request that either adds that if GCC is being used or fixes the warnings if they're harmful.

K.K.Lv · 12-04-2014 , 08:57 Re: about compile linux extension problem

@psychonic and I have fixed the warning as you said, anyway thx, maybe I have to try to fixed the error by myself before post the thread on the forum ;)
and now I think I know how to make a good AMBuildScript !
and I hope the next official version script will fixed that problem !
