首先说结论，折腾了半天，报了一堆错，放弃了。建议直接完整ubuntu环境，很顺利编译。

git repository

https://gitlab.com/dm38/padavan-ng.git

编译

首先遇到的问题是不能 build toolchain。 运行./clean_sources.sh，报错：

=================REMOVE-OLD-BUILD-TREE==================
make: /usr/bin/bash: Command not found
make: /usr/bin/bash: Command not found
/mnt/d/padavan-ng/toolchain/scripts/scripts.mk:63: recipe for target 'distclean' failed
make: *** [distclean] Error 127

运行./build_toolchain.sh报错：

================ START BUILDING TOOLCHAIN ==============
============== CLEANING OLD BUILD TREE =================
make: /usr/bin/bash: Command not found
make: /usr/bin/bash: Command not found
ct-ng:333: recipe for target 'clean' failed
make: *** [clean] Error 127
make: /usr/bin/bash: Command not found
make: *** No rule to make target 'mipsel-linux-uclibc'.  Stop.

查看toolchain目录下用到的是crosstool-ng。rosstool-ng文档说明需要执行：

  • ./bootstrap
  • ./configure --enable-local
  • make

但是最后make时报错：

CDPATH="${ZSH_VERSION+.}:" && cd . && /bin/bash /opt/rt-n56u/toolchain/scripts/missing aclocal-1.16
/opt/rt-n56u/toolchain/scripts/missing: line 81: aclocal-1.16: command not found

         You should only need it if you modified 'acinclude.m4' or

         The 'aclocal' program is part of the GNU Automake package:

         It also requires GNU Autoconf, GNU m4 and Perl in order to run:

搜索后发现需要执行命令：autoreconf -r -i

再次执行make

 cd . && /bin/bash /opt/rt-n56u/toolchain/scripts/missing automake-1.16 --foreign

看起来automake版本不对，确认版本：automake --version

automake (GNU automake) 1.15.1

apt search automake发现源里最高版本是1.15

下载安装automake

sudo apt-get autoremove automake
wget http://ftp.gnu.org/gnu/automake/automake-1.16.2.tar.gz
tar -xf automake-1.16.2.tar.gz
cd automake-1.16.2
./bootstrap
./configure
make
sudo make install
