如何为openwrt路由器编译pycups？

Question

我正设法为我的tl-wdr4300编译pycups。我使用debian稳定程序来编译。在

https://pypi.python.org/pypi/pycups

http://wiki.openwrt.org/doc/devel/crosscompile

第一个错误是：

make CC=mips-openwrt-linux-uclibc-gcc LD=mips-openwrt-linux-uclibc-ld CFLAGS=/home/linuxlover/openwrt/trunk/staging_dir/toolchain-mips_34kc_gcc-4.6-linaro_uClibc-0.9.33.2/usr/include/ LDFLAGS=/home/linuxlover/openwrt/trunk/staging_dir/toolchain-mips_34kc_gcc-4.6-linaro_uClibc-0.9.33.2/usr/lib/

error: command 'mips-openwrt-linux-uclibc-gcc' failed with exit status 1
make: *** [cups.so] Error 1

我知道这是个坏主意，但是我编辑了/usr/include/python2.7/pyport.h并更改了这个条件

第二个错误：

之后，我将cups、iconv.h和python2.7从/usr/include复制到/home/linuxlover/openwrt/trunk/staging_dir/toolchain-mips_34kc_gcc-4.6-linaro_uClibc-0.9.33.2/usr/include/

看起来您已经将gcc设置为链接器，而不是mips-openwrt-linux-uclibc-gcc
