build python 2.7.11 for mips

build pgen

• mkdir build.pc
• cd build.pc
• ../configure
• make Parser/pgen

因為在編譯 python 時，會用到自己的 pgen，可是 cross compile 編出來的當然不能用，只能先編一套 pc 版的出來。

build python

• 修改 Makefile.pre.in，把 pgen 換成 pc 版本。
  $(PGEN) $(GRAMMAR_INPUT) $(GRAMMAR_H) $(GRAMMAR_C) 改爲 ./build.pc/Parser/pgen $(GRAMMAR_INPUT) $(GRAMMAR_H) $(GRAMMAR_C)
• configure

  ./configure --build=i686-pc-linux --host=mips-linux --prefix=/mnt/python --disable-ipv6
• make
• make install
  會有些錯誤就不要理它了。

執行

• 把 /mnt/python 整個目錄想法子弄到 demo board 的 /mnt/python。
• 執行 /mnt/python/bin/python2.7

for realtek

• cp ../fib003_res/rtl819x/toolchain/msdk-4.4.7-mips-EB-3.10-0.9.33-m32t-131227b/lib/libpthread.so.0 /mnt/python/lib

• cp ../fib003_res/rtl819x/toolchain/msdk-4.4.7-mips-EB-3.10-0.9.33-m32t-131227b/lib/libm.so.0 /tftpboot/python/lib
• 執行前加上 export LD_LIBRARY_PATH=/mnt/python/lib 才能找到缺乏的動態檔。

問題排解

checking for resizeterm... no configure: checking for device files checking for /dev/ptmx... not set configure: error: set ac_cv_file__dev_ptmx to yes/no in your CONFIG_SITE file when cross compiling

configure 加上 ac_cv_file__dev_ptmx=no 便可

checking for resizeterm... no configure: checking for device files checking for /dev/ptc... not set configure: error: set ac_cv_file__dev_ptc to yes/no in your CONFIG_SITE file when cross compiling

configure 加上 ac_cv_file__dev_ptc=no 便可

使用 pc 版本的 pgen 便可。

修改 Module/Setup，把所須要的 module 加進去重編便可。
