Invalid gxp shader

[MrSilverstone]

Hi everyone.
I managed to display basic shapes using gxm thanks to libvita2d compiled shaders found on github. Now, I would like to use my own shaders. I found a tool (not legal) which let me compile my cg shaders to gxp. Unfortunately, when i try to use them, sceGxmProgramCheck return SCE_GXM_ERROR_INVALID_VALUE (0x805b0003).
How did xerpi manage to compile his shaders? Is there any non official but legal tool for compiling shaders?
I know that my gxp file is valid (i can check uniforms information with an other tool).
I tried to convert the gxp file to obj with ld (arm-vita-eabi-ld -r -b binary) and it didn't work. Same result using xxd to convert the gxp file to an unsigned char array.

Thanks for your help, and sorry for my english

I just found that vitashell used to be able to compile shaders. I found some code in this commit : https://bitbucket.org/TheOfficialFloW/v ... 770872a9c9
I found other informations on this repo https://github.com/frangarcj/vitahelloshader
