Help with Linux Builds

[zawata]

Ive been trying to build PPSSPP for my linux distro - Ubuntu 13.04
because
- the windows version doesnt work for me(OpenGL Errors)
- wine windows wont work for me(i dont even know what happens it just doesnt work)
- android build runs well but audio is choppy and video is terrible(if i increase the graphics then it runs terrible)

i have tried SDL, Qt(terminal) and QTCREATOR

when i run ./b.sh
after printing "Linking CXX executable PPSSPPSDL"
i get this string of errors :

when trying to build SDL:

Quote:$ git clone git://github.com/hrydgard/ppsspp.git && cd ppsspp
$ git submodule update -i
$ ./b.sh
$ cd build
$ ./PPSSPPSDL
bash: ./PPSSPPSDL: No such file or directory

when i try Qt in terminal :

Quote:$ git clone git://github.com/hrydgard/ppsspp.git && cd ppsspp
$ git submodule update -i
$ ./b.sh
$ cd Qt
$ qmake PPSSPPQt.pro && make
qmake: could not find a Qt installation of ''

when i try to compile PPSSPPQt.pro in QTCreator
i get this error(which im pretty sure is caused by some noob-ish mistake):

Quote::-1: error: No rule to make target `libCommon.a', needed by `PPSSPPQt'. Stop.

im probably doing something wrong
some noob mistake, please help

P.S. going out of town monday morning 9/30, will not return until thursday 10/3
