[VIM插件]fedora22编译vim7.4对perl组件支持的问题

　　在fedora22下，重新编译安装vim7.4的时，在编译perl组件支持时,出现如下错误：

/bin/perl -e 'unless ( $] >= 5.005 ) { for (qw(na defgv errgv)) { print "#define PL_$_ $_\n" }}' > auto/if_perl.c
/bin/perl /usr/share/perl5/ExtUtils/xsubpp -prototypes -typemap \
    /usr/share/perl5/ExtUtils/typemap if_perl.xs >> auto/if_perl.c
Can't open perl script "/usr/share/perl5/ExtUtils/xsubpp": No such file or directory
Makefile:: recipe for target 'auto/if_perl.c' failed
make[]: *** [auto/if_perl.c] Error
make[]: Leaving directory '/home/$usr/vim/src/vim74/src'
Makefile:: recipe for target 'first' failed
make: *** [first] Error 

找了下，发现fedora22的perl5的$lib路径和原先系统的竟然不一样了，在$PELR5/vendor_perl/ExtUtil/中才有连接文件xsubpp。

接着修改了编译的指向路径，接着编译，却报错：

objects/buffer.o: In function `free_buffer':
/home/$usr/vim/src/vim74/src/buffer.c:: undefined reference to `perl_buf_free'
objects/ex_docmd.o:(.rodata+0x4678): undefined reference to `ex_perl'

检查src/auto/中的if_perl.c文件，发现竟然是空得，生成失败了。

根据makefile或者第一个报错的指引，找到生成if_perl.c的命令，手动生成即可：

/bin/perl -e 'unless ( $] >= 5.005 ) { for (qw(na defgv errgv)) { print "#define PL_$_ $_\n" }}' > auto/if_perl.c
/bin/perl /usr/share/perl5/ExtUtils/xsubpp -prototypes -typemap \
    /usr/share/perl5/ExtUtils/typemap if_perl.xs >> auto/if_perl.c

 注意xsubpp的路径。
