GLES2.0 Samples run failed on imx6 linux 3.0.35

forrestjr — Tue, 29 Mar 2016 09:06:44 GMT

imx6 Linux3.0.35(L3.0.35_4.1.0_130816) run i.MX6 Graphics SDK Sample ,the GLES2.0 Samples run failed and GLES1.1 OpenVG run ok.

about failed info :

1、build GLES2.0 samples for FBDEV

2、GLES2.0 Samples run failed log :

root@freescale /mnt/mmc/GLES20_fbdev$ ./01_SimpleTriangle

01_SimpleTriangle: SimpleTriangle.c:283: main: Assertion `init()' failed.

Aborted

root@freescale /mnt/mmc/GLES20_fbdev$

And debug this error found glCompileShader() run failed,why?

if use PrecomplieShader(not run glCompileShader()),sample run ok.

L3.0.35_4.1.0_130816 BSP not support GLES2.0?Only support GLES1.1?

Regards,

forrest

Hi forest,

You can refer to Compile IMX6_GPU_SDK with L3.0.35_1.1.0 and L3.0.35_4.0.0 in our community. Hope it can help you.
Have a great day,
Dan

Thank a lot,but the problem still exitsts.

Reference "Compile IMX6_GPU_SDK with L3.0.35_1.1.0 and L3.0.35_4.0.0",On imx6 Linux3.0.35(L3.0.35_4.1.0_130816) still only run GLES1.1 and OpenVG Samples.

run GLES2.0 Sample for FBDEV still failed,Eg. run 01_SimpleTriangle

$./01_SimpleTriangle

$ glCompileShader error

$ 01_SimpleTriangle: SimpleTriangle.c:283: main: Assertion `init()' failed.

$ Aborted

in SimpleTriangle.c

// Compile the shaders

GLuint hVertexShader = glCreateShader( GL_VERTEX_SHADER );

glShaderSource( hVertexShader, 1, &g_strVertexShader, NULL );

glCompileShader( hVertexShader );

// Check for compile success

GLint nCompileResult = 0;

glGetShaderiv( hVertexShader, GL_COMPILE_STATUS, &nCompileResult );

if( 0 == nCompileResult )

{

char strLog[1024];

GLint nLength;

glGetShaderInfoLog( hVertexShader, 1024, &nLength, strLog );

printf("glCompileShader error \n");

return FALSE;

}

The Shader Compile failed,why? need other config?
