Compiling "standard" HL2 plugins with Cygwin

squeeek · **Author**

I know there are loads of topics and a Wiki about this stuff, but I just cant find the one that suits my needs.
Ive got the working plugin for windows servers, written with VS.net 2003.
Ive installed Cygwin, and unpacked the CrossTool with it.

My problem is, that I cant figure out, what the hell should I write to the makefile variables.
Every help is appriciated

or at least point me to the neccesary thread... =/
thank you in advance

I really don't know much about makefiles. I would suggest taking a look at the makefile for the sample_mm plugin from Metamod: Source. I know you are doing a standard plugin, but it should be basically the same except you don't need the paths to sourcemm.

Also, search for tutorials/howtos about gcc and makefiles.

Take a look at this tutorial I wrote a while back.

Its aimed at compiling for sourcemm but the principles are still the same. You can remove all referances to SMM_ROOT from the sample makefile provided.

jeeez, thanks guys!
now, my next problem is with the crosstool. I cant make out any logic in its folder-structure (i know its my false

SOURCE_DIR : the root of the unpacked SDK where "Everything_SDK.sln" and "Game_sdk.sln" are. (i hope so)
GAME_DIR : understood, thats simple. linux binaries

# compiler options (gcc 3.4.1 or above is required)
CC=/usr/bin/gcc
CPLUS=/usr/bin/g++
CLINK=/usr/bin/gcc
CPP_LIB=/usr/lib/libstdc++.a /usr/lib/libgcc_eh.a

My problem is with these lines. Ive found the first three in the unpacked crosstool: "cygwin\opt\crosstool\gcc-3.4.1-glibc-2.3.2\i686-unknown-linux-gnu\i686-unknown-linux-gnu\bin"
ar.exe, as.exe, c++.exe, g++.exe, gcc.exe etc...
Even got the libstdc++.a in the appropriate lib directory of that lengthy path.

The only "libgcc_eh.a" that Ive found within the crosstool folders was in "cygwin\opt\crosstool\gcc-3.4.1-glibc-2.3.2\i686-unknown-linux-gnu\lib\gcc\i686-unkown-linux-gnu\3.4.1"
Though the CPP_LIB should point to a single directory. What am i supposed to do? Im prettry sure something exra has to be done with the unpacked crosstool before you can use it for compiling.
Copy-paste? I wont try it all by myself, im sure i would mess up everything

all the best!

i've modified c0ldfyr3's makefile, and typed "make ratechecker" instead of "make"

well... ive got this: http://sourcespray.atw.hu/cygwin_err_01.jpg

I guess the main problem is that it doesnt include the header files, therefore it cant find the classes, etc. So..... howto?

squeeek · 08-14-2006 , 05:35 Re: Compiling "standard" HL2 plugins with Cygwin

i copied everything from the ratechecker dir to the public dir. i ran the make rateckecker from there, and now i've got so many errormessages, that the window is too small to display them =/

squeeek · 08-14-2006 , 09:07 Re: Compiling "standard" HL2 plugins with Cygwin

OK, i gave it up.
the linker wont include my "include" dirs "because linking not done", and i get a Segmentation fault error message from cc1plus.

I've read everything i've found on the net, but its a bit hard to fix the error with static help... I know you guys can do it ;)

You need to add the include directories.

Edit: I see.. you need the -I flag infront of the paths on the INCLUDE makefile variable and not just the first one.
