Cannot build on ArchLinux 64bit

[minhnhdo]

Solution:

• Directly #include <cstring> or #include <cstdio> into the offending files

or

• Centralize the missing #includes into one file and include this file in the offending files

Keep sending pull requests with fixes :)

[minhnhdo]

Do you want me to include the missing header into each file? Or do you prefer a centralized include?

[hrydgard]

Oh sorry, missed that you were asking a question.

Please add them to all of the files, centralized includes tend to grow over time and slow down the build.

It's odd that this include problem isn't an issue on Mac or Android, it builds fine on those..

[minhnhdo]

I suspect the compiler implicitly links the program with stdlib functions

[minhnhdo]

after fixing a bunch of missing #includes and missing CMake linking directives, I'm able to run the program. However, running the program (./SDL/build/ppsspp) would only give me a blocky splash screen in the emulator, followed by a blocky menu. Is this intended?

[hrydgard]

No, it should work - it needs assets/ui_atlas.zim to be accessible though so you need to run it from the right directory. I hope to find some way to build the graphics into the binary later.

(try running ./buildassets.sh in /SDL to copy over the atlas from the android directory. yeah I know this is a bit silly)

[minhnhdo]

it runs perfectly after I have copied the assets/ folder into the same folder containing ppsspp executable.
