Compile error. Version question.

[AaronP]

First the question. What is the latest version of GE? The precompiled binary is listed as 1.4, but if I want to submit a bug on sourceforge, I can submit it as being for version 2.0?

Excuse me for the stupid question, but I'm new and not familiar with all the minutia of software development.

Lastly the compiler error. Actually, there have already been a couple that have been really minor things that I've been able to fix myself, but this is a linker error and I don't know much about those.

Arch Linux i686
GCC version 4.6.2
Glib version 2.15-3

I don't know all the details about how names are mangled during compilation, but atan2() is a function in math.h. atan2() appears a lot throughout the source, but perhaps it has something to do with /gameEngine/EiC/include/math.h? I'm not sure why you'd need to package std libraries with GE. :/

The current version is the 1.4.0 (the 1.5 still in development).
I think there are some comflict in your system with the libm library.
Using the "-lm" switch may solve the problem.

[AaronP]

Builds but segfaults immediately. Imma build with GE_DEBUG and see if I can't figure it out.

EDIT:
Oh, I forgot to cp the res contents over.

Ok, I got it working. Any way I can help? I can make a small patch to get the build working. I got no other machine to test on, though.

[makslane]

Send me your makefiles

[AaronP]

I ran svn diff. I don't know if I did something wrong because there's also a bunch of lines that I didn't change. I don't have much experience yet with version control systems, sorry.

The makefile wasn't the only issue. You also need to replace two blank #elif's in kyra/engine/scrap.c with #else. The C preprosessor is another subject I don't know enough about, but the change is detailed here.

http://gcc.gnu.org/gcc-4.4/porting_to.html

So I'm packaging the patch and also the makefile as requested.

EDIT:
I notice the makefile in question is generated by dev-c++? Looking at things, the dev-c++ issue seems a bit complicated. It was unmaintained for a long, long time. Seems someone else has taken up the project, though, and made a bunch of bugfixes and shipped it with a recent gcc version.

As alternatives, there is also wxdev-c++ and also Code::Blocks which has the advantage of working on windows, mac, linux, and freebsd.

Thanks!

No problem. By the way, I tested out the patch by checking out a fresh copy of GE and running

Code: Select all

patch -p0 < lmakefix.patch

And the patch worked just fine. Don't know why that didn't occur to me before! Anyway, not sure how to do that in windows other than to download the windows version of patch and using the awful windows command line environment. You'd prolly also need to convert the .patch (which is just a text file) to dos format using a text editor like notepad++ or something.
