Trying to build the 5.1.5 using cmake -> Visual studio 10 Win64
kovarex

Hello fellow allegro users,

along trying to figure out the resizing problem (https://www.allegro.cc/forums/thread/612025), I tried to compile the allegro using the default system (we use custom build system in our game).

So I downloaded fresh 5.1.5 allegro and ran this command from vs command prompt as usual: 

cmake -G "Visual Studio 10 Win64"

When it finished, I opened ALLEGRO.sln and tried to build it.

This is what I got in the allegro_image project:

I guess that Gdiplus is some external library but I have no idea why it is missing.

Any ideas?

You can disable gdiplus, the cmake option would be NATIVE_IMAGE_LOADERS or something like that. Why cmake doesn't find it would be the more interesting question of course.

Does the regular (non-Win64) build work?

kovarex

Everything compiled fine without the Win64.

Btw, I wanted to try some example that could be used to test the the resizing issue, but it seems that all the example windows are not resizable, is there some suitable example that could be used for this? (Or simply extended).

I guess that the only chance for me to find out where is the problem with the resizing is to get get the the allegro git repository and and to try to localise the problem by searching the commit.

How about ex_resize or ex_resize2?
