Hiya,

I'm trying to compile love (not because I'm masochistic, but because I'm on 64bit and there is no .deb), but I get this error:

Code: Select all

vadi@ubuntu-laptop:~/Programs/love$ make
Making liblove ...
Making love ...
Making love_chipmunk ...
src/chipmunk/chipmunk/cpCollision.c: In function ‘int findVerts(cpContact**, cpPolyShape*, cpPolyShape*, cpVect, cpFloat)’:

make[1]: *** [obj/chipmunk/cpCollision.o] Error 1
make: *** [love_chipmunk] Error 2

It looks like some error in the code to me, but I'm not sure. Can anyone clear this up and see if I did something wrong?

Here's my version of gcc by the way, this is on Ubuntu 8.04:

vadi@ubuntu-laptop:~/Programs/love$ gcc -v

Ok, that's weird. I have the exact same version of gcc as you do, and I built the binaries without even a warning. (32-bit, however).

Try removing "love_chipmunk" in the top line of the makefile. It's not really needed right now

(it's never loaded in 0.3.0). I know that's not a solution in the long run, but it may work as a quick fix for now.

I'll download Ubuntu 64-bit and install on another virtual machine, so I can give it a go myself. If all the required libraries are available in 64-bit, I see no reason why we can't start providing 64-bit packages as well.

Let me know what happens. 8-)

Thank you, that worked.

Stick these modify version in love/src/chipmunk/chipmunk and it will compile under x86_64..

Excellent, thanks! 64-bit .deb is underway. 8-)

Well, the OP also said that Makefile does not work with -j (multiple jobs compiling love).

I don't have the knowledge of Makefile-fu nor do I have the time to do it, but here is how, I'm sure original maker of Makefile can easily do..

Use $(MAKE) instead of make
Make building liblove a dependency of building everything else so it can link to liblove.a

Ok, tido can probably fix that easily.

Vadi: VirtualBox does not support 64-bit (yet), so I can't maintain a binary. Sorry.

Yeah that it doesn't :/.

What if I compiled you the stuff and sent it?

Thank you for volunteering.

.. but I'm not sure if that would work. I'll ask tido if the same script can be used.
