[Q] Porting asterisk to Linksys WRTP54G router

The Linksys RTP300/WRTP54G routers and PAP2v2 are all based on a TI AR7
chipset. There has been some Work-in-Progress to port OpenWRT firmware
to the AR7 platform for quite sometimes and never fruitfull. I am in a
need to port and run an asterisk on my Linksys WRTO54G router. For
this, I tried the TI-toolchain that I extracted from a Linksys WAG54GV2
firmware source I downloaded from a Linksys FTP site a las the
compilation can not proceed because of missing ncurses and termcap
libraries. I rebuilt these two libraries and am still not able to
finish compiled asterisk for AR7, i.e. errors on final linking stage. I
wonderd if anyone out here has managed to port/compile asterisk source
code to an AR7 platform. If so, can you please help?
