需要安裝 perl的5.22.1
ubuntu 16.04 編譯modem出現Can't locate Switch.pm in @INC
編譯39 GO 的modem出現報錯，查看 perlbrew版本爲5.22.1
gcc 版本切成4.8，
[PERL] : v5.22.1 [NOT RECOMMENDED] !!!
[MAKE] : GNU Make v3.81 [OK] !!!
[SHELL] : GNU bash v4.3.48 [HIGHER THAN RECOMMENDED] !!!
[COMPILER] : v4.9.2(2016.05-08) [OK] !!!
我們不管它的編譯環境，因爲當我把perlbrew版本切成5.14.2，編譯的時候還是會報錯，所以我們直接編譯，
.
下面是編譯報錯的提示：
Can’t locate Switch.pm in @INC (you may need to install the Switch module) (@INC contains: /etc/perl /usr/local/lib/x86_64-linux-gnu/perl/5.22.1 /usr/local/share/perl/5.22.1 /usr/lib/x86_64-linux-gnu/perl5/5.22 /usr/share/perl5 /usr/lib/x86_64-linux-gnu/perl/5.22 /usr/share/perl/5.22 /usr/local/lib/site_perl /usr/lib/x86_64-linux-gnu/perl-base . ./pcore/tools/ ./common/tools/MemoryUtility/ ./pcore/tools/ ./common/tools/MemoryUtility/ …/ …/…/…/pcore/tools/ ./pcore/tools/ ./common/tools/MemoryUtility/ ./pcore/tools/ …/ ./pcore/tools/ ./common/tools/MemoryUtility/ ./pcore/tools/ ./pcore/tools/ ./pcore/tools/ ./pcore/tools/) at common/tools/AutoGen/postBuild/update_mpu_table.pl line 190.
需要補充安裝兩個東西：
sudo apt-getinstall libswitch-perl 安裝perl 編譯modem
sudo apt-get install libxml2-utils
之後，就可以正常編譯android系統了。
