Hi all,
I'm trying to do some GLSL shaders with MacRuby. However, I'm a bit stumped as
to how to call glGetShaderInfoLog if the shader compilation fails. The C
function's prototype is:
void glGetShaderInfoLog(GLuint shader, GLsizei maxLength, GLsizei * length,
GLchar * infoLog);
I couldn't find any docs on how Pointer.new_with_type, so I tried a few things,
such as:
log_info = Pointer.new_with_type('c', 4096)
length = Pointer.new_with_type('i')
glGetShaderInfoLog(@shader_id, 4096, length, log_info)
However, I get the error:
TypeError: can't convert Pointer into String
It seems that the bridge wants log_info to be a String object. But, using a
String causes a bus error. I'm expecting that the bridge isn't expecting the
string to be mutated.
Any suggestions would be appreciated!
