Add -lpspgu to your libs.
You should have a line in the makefile like:
That will get rid of the 'undefined reference to sceGu...' messages.
The warning messages at the top (pointer from integer) are because you are using the wrong datatypes, I haven't used the Gu functions much so I can't help you more there.

sceGuTexImage(0,512,512,512,logo_temp);
sceGuDrawArray(GU_TRIANGLES,GU_TEXTURE_32BITF|GU_COLOR_8888|GU_VERTEX_32BITF|GU_TRANSFORM_3D,6,0,vertices);
Both the arguments in red above are pointers. for sceGuTexImage is it a pointer to your texture and for the sceGuDrawArray it is a pointer to your vertices. In your code you have these defined as the datatype int.
So you should either declare your variables as pointers or make a typecast in your code.
sceGuTexImage(0,512,512,512,(const void *)logo_temp);
sceGuDrawArray(GU_TRIANGLES,GU_TEXTURE_32BITF|GU_COLOR_8888|GU_VERTEX_32BITF|GU_TRANSFORM_3D,6,0,(const void *)vertices);

I found the error.
But now the flipscreen and initgraphics are undefined reference which library i need to include.
