Hello all,
I am experimenting luaJIT and its FFI. Unfortunately, while trying to
process a rather big loop, the trace aborts on the first C function
call done via the FFI.
Here, I load openGL symbols in "gl" via the FFI. When glClear (see
pasted code) is called, trace aborts with error "symbol not in cache"
here is the code:
function render_system:render()
gl.glClear(gl.GL_COLOR_BUFFER_BIT)
-- all squares first
local sq = self.render_world.square
gl.glBegin(gl.GL_QUADS)
for _,square in pairs(sq) do
local c = square.color
local p = square.center
local s = square.size
gl.glColor3f(c[1],c[2],c[3])
gl.glVertex3f(p[1]+s[1], p[2]+s[2], p[3]+s[3])
gl.glVertex3f(p[1]+s[1], p[2]-s[2], p[3]+s[3])
gl.glVertex3f(p[1]-s[1], p[2]-s[2], p[3]+s[3])
gl.glVertex3f(p[1]-s[1], p[2]+s[2], p[3]+s[3])
end
gl.glEnd()
end
AM I doing something wrong? Or is it the normal behaviour?
I just fetched the last luaJIT version from git HEAD.
Thanks!
Ben
