# 进入 native 目录下进行编译和安装 mod_jk
/usr/local/tomcat-connectors-1.2.48-src/native/configure --with-apxs=/usr/bin/apxs && make && make install- The following error occurs when executing the previous command
line 81: aclocal-1.15: command not found
WARNING: 'aclocal-1.15' is missing on your system.
You should only need it if you modified 'acinclude.m4' or
'configure.ac' or m4 files included by 'configure.ac'.
The 'aclocal' program is part of the GNU Automake package:
<http://www.gnu.org/software/automake>
It also requires GNU Autoconf, GNU m4 and Perl in order to run:
<http://www.gnu.org/software/autoconf>
<http://www.gnu.org/software/m4/>
<http://www.perl.org/>
make: *** [Makefile:579: aclocal.m4] Error 127
