I was able to remove the problem of Unknown symbols by linking the proper libraries. Now the problem got reduced to the following messages. # insmod brcmstfb.ko brcmstfb: Unknown symbol printf brcmstfb: Unknown symbol malloc brcmstfb: Unknown symbol free insmod: cannot insert `brcmstfb.ko': Unknown symbol in module (2): No such file or directory # for the above problem i had tried to link "libgcc.a " but those symbols are also undefined in it also. RECAP: While running the cross compiled directFB example on MIPS chip,* We tried to install the framebuffer driver(command given above) after creating the node fb0. APPROACH: Actually the code of frambuffer driver consists of usual kernel framebuffer code and properitiary graphics lib code. The properitiary graphics lib code is using malloc,print and free from < stdlib.h> and that is why those symbols are coming undefined. Could anybody help in this regard? Thanks in advance. kaka ---------- Forwarded message ---------- From: kaka <[email protected]> Date: Oct 12, 2007 6:33 PM Subject: Error opening framebuffer device/Unknown symbol register_framebuffer To: [email protected], [email protected] . > *Hi All,* > > *While running the cross compiled directFB example on MIPS chip,* > > * > > > We tried to install the framebuffer driver(command given at the bottom) and we have already created the node fb0.* > > *We are getting the following error, * > > *Can anybody help in this regard ?* > > *Thanks in Advance.* > > # ../../cross_directfb/simple_mips > > =======================| DirectFB 1.0.0 |======================= > (c) 2001-2007 The DirectFB Organization (directfb.org) > (c) 2000-2004 Convergence (integrated media) GmbH > ------------------------------------------------------------ > > (*) DirectFB/Core: Single Application Core.
