GAE/Linux Compiling ("too large for 'long' type" error)

[mersinliali]

Hi,
First of all, my apologies regarding possible mistakes in the language.

I'm very excited seeing the page: https://docs.megaglest.org/GAE/Linux_Compiling

I've compiled the GAE as explained in that page, and finally I've managed to play with the new engine. Everything seems alright. However, while cmake'ing, I have these warnings:

How can I fix these errors (although I can play the game that way)?

The game should be playable, only the test suite did not compile.

I think you can ignore the CMake warnings. Just try to run the map editor and see if it works.

The compile error seems to be in the macros IF_MULT_OVERFLOW in shared_lib/include/math/fixed.h:193 and IF_DIV_OVERFLOW below. They only get activated in the test_suite because of test/datastructs/fixed_point_test.h:19. I don't really see the problem and it builds for me just fine. Maybe silnarm has an idea...

Could you tell us the gcc version and CPU architecture you use.

[silnarm]

Looks like gcc wants to put all integer constants in 32 bits... Interestingly it only gave me warnings, should be ok now anyway (fix committed).

Hi mersinliali,

  If you do a 'svn update' the test suite should compile ok now.

  For the CMake warnings I can't help, it seems your system has duplicate libs in /usr/X11R6/lib and /usr/lib but it doesn't seem to be causing any problems, so I wouldn't worry about it.

Cheers.

Hi,
Thank you very much. It works now. As you said, there is a symlink (X11R6) under /usr which links to /usr itself, so, I guess, it reads twice while compiling.
Best wishes,
Ali
