[lwip-users] problem of rtl-lwip!

[liu kun]

Hi,list
I want use rtl-lwip with my rtlinux (2.4.18+rtlinux3.2-pre1) and my 
rtlinux has done well. So I patch the bigphysarea-2.4.20 fallow the 
FAQ,(because I can’t find the patch with 2.4.18),but when I rebuild my 
kernel I can’t find the information of bigphysarea in /proc, after I “make
” my rtlinux ,the rtlinux is ok ,then I  “make” the rtl-lwip, but it 
failed, it seems the bigphysarea is not properly installed. 
Do “make” in the rtl-lwip 0.4, it’s shows:
/usr/src/rtlinux-3.2-pre1/network/RTL-lwIP-0.4/src/arch/Rtlinux/sys_arch.c: 

In function’sys_init’:
/usr/src/rtlinux-3.2-pre1/network/RTL-lwIP-0.4/src/arch/Rtlinux/sys_arch.c:
736:’RTL_SIGRTMIN’ undeclared (first used in this function)
…… ……
/usr/src/rtlinux-3.2-pre1/network/RTL-lwIP-0.4/src/arch/Rtlinux/sys_arch.c:816:

warning:implicit declaration of function ‘timer_delete’.
Make***[/usr/src/rtlinux-3.2-pre1/network/RTL-lwIP-0.4/src/arch/Rtlinux/sys_arch.o] 
Error1

Anyone can tell me how to install the rtl-lwip or give me some documents 
about this? should I choose the patch bigphysarea-2.4.4 ? thanks
