Linking DX9 lib? -,- (Mingw)

[Blackroot]

I looked around google and mingw's FAQs, but it doesnt seem to want to link.

I've been trying this:

$ g++ C:\\Spacerpg.o -o C:\\Spacerpg.exe -mwindows -l C:\\DX9\\Lib\\x64\\d3d9.lib

$ g++ C:\\Spacerpg.o -o C:\\Spacerpg.exe -mwindows -L C:\\DX9\\Lib\\x64\\ -l d3d9.lib

$ g++ C:\\Spacerpg.o -o C:\\Spacerpg.exe -mwindows -llib C:\\DX9\\Lib\\x64\\d3d9.lib

$ g++ C:\\Spacerpg.o -o C:\\Spacerpg.exe -mwindows -L C:\\DX9\\Lib\\x64 -llib d3d9.lib

None of them are compiling correctly, bah... >.<

None of them are compiling correctly

What do you mean by correctly?

You don't use double-backslashes on the command line. Use single ones.

Other than that, if it is a linking problem, see if "C:\\DX9\\Lib\\x64\\d3d9.lib" exists.

If you can't get it to work post the exact error message[s].

Ah, I forgot to mention I'm using mingw & msys. It doesnt work right with single backslashs. I could use single forward slashs, but eh.

The exact error is:

$ g++ C:\\Spacerpg.o -o C:\\Spacerpg.exe -mwindows -L C:\\DX9\\Lib\\x64 -l d3d9.lib
C:\Mingw\bin\..\lib\gcc\mingw32\3.4.2\..\..\..\..\mingw32\bin\ld.exe: cannot find -ld3d9.lib
collect2: ld returned 1 exit status

Its the same for all of them. And C:\DX9\Lib\x64\d3d9.lib does exist. (I installed it there.)

You have a mix of double-backslashes and single-backslashes there. That's probably not going to work.

BTW, when you use -lname, GCC looks for libname.a in the library search paths (which you can add to with -L). I'm not sure how you handle .lib files; try just adding it on the command line like a C source file.

Okay, I found a thread on this: http://www.gamedev.net/community/for...10&gforum_id=0

You can't use the .lib files with Dev-C++. You need to get the lib*.a files (which you use with -l). When I find where to get them I'll let you know.

[edit] You could use MinGW. I don't know if this will work with Dev-C++ but I suspect it will: http://rpmfind.net/linux/RPM/sourcef....3-1.i586.html [/edit]

[edit=3] Hmm, maybe you can use the .lib after all: http://www.spacejack.org/games/mingw/mingw-dx.html
I'm going to stop searching now. Good luck. Let us know if it works. [/edit]

I tried method 2, I dont see how to install dev pack files?

I also tried method 3

$ g++ C:\\Spacerpg.cpp -o C:\\Spacerpg.exe -mwindows -I C:\\DX9\\Lib\\x64\\d3d9.lib
cc1plus.exe: C:/DX9/Lib/x64/d3d9.lib: not a directory

Doesnt work, even though I'm sure its looking into the right spot. Seems like -I is specifying a folder location?

You should create mingw compatible dx libs from the respective dlls using the reimp tool from mingw-utils; you can also use the ms directx libs themselves.

For example (it's a while since I fiddled around with this so this may not be entirely accurate) copy the following ms directx libs to a separate directory:

• d3d8.lib
• d3d9.lib
• d3dx8d.lib
• d3dx9d.lib
• d3dxof.lib
• ddraw.lib
• dinput.lib
• dinput8.lib
• dplayx.lib
• dsetup.lib
• dsound.lib
• dxtrans.lib
• ksproxy.lib
• ksuser.lib
• msdmo.lib
• quatz.lib

Then from the command line(cmd.exe), cd (change directory) to that temporary directory, and use reimp 'libname' on each individually, or just type:

for %f in (*.lib) do reimp %f

to do them all together. Since these are non-standard mingw libs it would be advisable to create a new subdirectory of your mingw lib directory and copy all the libxxxx.a mingw compatible libraries you just created to it; when building directx applications you just have to ensure that subdirectory is in the library path (-L switch). Do the same with the ms directx headers; in this case you'd use the -I switch with the path to the dx9 'include' directory to ensure those files are in the include path for your mingw directx projects.

Some of the ms dx libs contain statically linked code which needs to be built into your application. For these you have no choice but to link directly with them - just use the explicit full name of the required library rather than usual -llib_name syntax.

You'll quickly find out which are which from the linker errors ('undefined reference' to function xxxx).

Alternatively, you might want to consider using msvc-express which will be good to go once you've configured it to use the psdk and the dx9 sdk.
