標題: Gentoo下建立DD-WRT交叉編譯環(huán)境
用的是Gentoo Linux Kernel版本2.6.28.7

從DD-WRT官方網(wǎng)站下載Toolchains
地址:http://www.dd-wrt.com/dd-wrtv2/downloads/others/sourcecode/toolchains/gcc.3.4.4-broadcom-mipsel.tar.bz2

其中有如下幾個版本:
all_toolchains_amd64.tar.bz2                For AMD64 CPU
gcc-3.3.5-openwrt.tar.bz2                   在OpenWRT環(huán)境下
gcc-3.4.4-crossmipsel-AMD64.tar.bz2          For AMD64 CPU
gcc.3.4.4-broadcom-mipsel.tar.bz2          一般的X86 CPU
toolchains.darwin.ppc.sp1.tar.bz2          PPC CPU下Darwin系統(tǒng)
toolchains.x86.debian.sp1.tar.bz2          X86下的Debian系統(tǒng)

我使用的路由器是貝爾金7231-4P,MIPS類CPU,BROADCOM芯片

下載toolchains后解壓,我放在/home/linyin/.opt/
修改用戶.bashrc添加:export PATH=$PATH:/home/linyin/.opt/openwrt/bin

寫個C程序:
  1 #include
  2 int main()
  3 {
  4       printf("Hello,DD-WRT\n");
  5       return 0;
  6 }

交叉編譯它:
[email=linyin@linyin]linyin@linyin[/email]
~ $ mipsel-linux-gcc -o test test.c
查看可執(zhí)行文件類型:
[email=linyin@linyin]linyin@linyin[/email]
~ $ file test
test: ELF 32-bit LSB executable, MIPS, MIPS32 version 1 (SYSV), dynamically linked (uses shared libs), not stripped
OK,放到DD-WRT下就可以執(zhí)行了... =)
