/home/milian/projects/qt5/qtwebkit/Source/WebCore/platform/graphics/OpenGLShims.cpp: In function 'bool WebCore::initializeOpenGLShims()':
/home/milian/projects/qt5/qtwebkit/Source/WebCore/platform/graphics/OpenGLShims.cpp:192: error: invalid conversion from 'void (*)(GLuint, GLsizei, const GLchar* const*, const GLint*)' to 'void (*)(GLuint, GLsizei, const char**, const GLint*)'

The reason here is that WebKit defines

typedef void (GLAPIENTRY *glShaderSourceType) (GLuint, GLsizei, const char**, const GLint*);

which is compatible to the Desktop OpenGL and older OpenGL 2 ES versions of glShaderSource. Yet recent OpenGL 2 ES versions have a different signature for this method:

typedef void (GLAPIENTRY *glShaderSourceType) (GLuint, GLsizei, const char* const*, const GLint*);

See e.g. http://www.khronos.org/opengles/sdk/docs/man/xhtml/glShaderSource.xml (old documentation, same signature as used by webkit)
and then compare to the actual gl2.h header: http://www.khronos.org/registry/gles/api/2.0/gl2.h - it contains:

GL_APICALL void         GL_APIENTRY glShaderSource (GLuint shader, GLsizei count, const GLchar* const* string, const GLint* length);
