龙芯初编译 dev-3210

关于pmon的一些命令选项：
  3   make cfg     配置pmon
  4   make tgt=rom 生成flash的烧写的bios:gzrom
  5   make tgt=ram 生成可以网络加载的bios:gzram
  6   make tgt=zlib_rom 生成flash的烧写的bios:zlib_gzrom
  7   make tgt=zlib_ram 生成可以网络加载的bios:zlib_gzram
  8   make tgt=sim 压缩算法linux下仿真
需要先生成pmoncfg，以便对pmon进行配置。

编译3210的pmon，遇到不少错误：
as：无法识别的选项“-G”
mips-elf-gcc: installation problem, cannot exec `cpp0': ?????????
等，最后在一台电脑上无论如何是编译不过去。搜索了一下这个解决方案，貌似也行不通。
”是 -I 搜索路径的问题，
修改 lib/libc/Makefile , lib/libm/Makefile, lib/libz/Makefile 文件
#CPPFLAGS=      -I$M ${MLIBCPPFLAGS} -U_KERNEL
CPPFLAGS=       -I. -I.. -I../../include \
                -Iarch/mips -I../../sys/sys -I../../sys \
                -I../../Targets/Bonito2fdev/compile/Bonito.2feva \
                -I../../Targets/Bonito2fdev/compile/Bonito.2feva/machine \
                -I../../sys/arch/mips/include   \
                -D_KERNEL -D__OpenBSD__ -DPMON -D__PMON__ \
                -mno-abicalls -mips3 -mmemcpy -mcpu=r4000   \
                -U_KERNEL -Wall -Wstrict-prototypes -Wno-uninitialized \
                -Wno-format -Wno-main -O2 -G 0 -nostdinc        \
                ${CLIBCPPFLAGS} -U_KERNEL
再 make tgt=rom 就可以了， “

整的来讲，觉得这个pmon给改的是比较糟糕的，编译配置的反复切换目录，而且Makefile文件分布缺乏简单的层次感，文件内容也是超常规，没有很多开源软件那样的清晰美。
在编译过程对路径导出貌似源码就有问题，需要按照手册安装目录，而不允许安装在到指定目录（工程师说是默认路径索引就在一个地方），会出现问题，这个是很失败的，容易遇到各种错误，实在没有什么好感。
求全责备没有用，刚开始或许千头万绪难以尽善尽美，期待改进。

原来没弄明白是什么错误，在另外一台电脑上编译一切顺利。上课回来的时候忽然在想是不是开了distcc的缘故，会默认调用集群编译，回来关了distcc，错误依然如故。
（如何为distcc指定编译器？？）
后来发现是因为电脑新装系统的缘故，缺少一个库
$ sudo aptitab instab libncurses5-dev
$ make menuconfig  ok

$ make
提示找不到命令gawk，
$ sudo aptitab instab gawk
$ make
基本上来讲，这个就比较顺利。可能是因为被修改的少的缘故吧！：）
