运行make 
出现
./crypto/proposal/proposal_keywords_static.txt > crypto/proposal/proposal_keywords_static.c
缺少gperf所致
sudo apt-get update
sudo apt-get install gperf


出现undefined reference to `proposal_get_token_static' 因为运行make clean 并没有删除初始化的make文件，
运行make maintainer-clean


出现configure: error: GNU Multi Precision library gmp not found
安装gmp库
apt-get -y install libgmp3-dev

出现
./configure: line 19902: syntax error near unexpected token `soup,'
./configure: line 19902: ` PKG_CHECK_MODULES(soup, libsoup-2.4)'




sudo apt install libsoup2.4-dev
pkg-config --modversion libsoup-2.4
运行
sudo ldconfig
sudo updatedb
locate libsoup-2.4.pc
显示文件的位置
运行 pkg-config --modversion libsoup-2.4
测试是否成功
然后重新运行autogen.sh


出现
/bin/bash ../../ylwrap settings/settings_parser.y y.tab.c settings/settings_parser.c y.tab.h `echo settings/settings_parser.c | sed -e s/cc$/hh/ -e s/cpp$/hpp/ -e s/cxx$/hxx/ -e s/c++$/h++/ -e s/c$/h/` y.output settings/settings_parser.output -- yacc -v -d
