apache_1.3.12,php4.0bx,informix安装心得
apache|心得
在Linux下安装apache_1.3.12,php4.0bx,informix时，先安装好informix，在装apache和php时要注意INFORMIXDIR,INFORMIXSERVER的环境变量要设，PATH要加上$INFORMIXDIR/bin，因为编译apache时要用esql；若无则错。
装apache_1.3.12和php-4.0b4pl1很顺利，需注意的是在configure apache时，变量--activate-module=src/modules/php4/libphp4.a 在src/modules/php4/下原本有个文件libmodphp4.a,Linux的Tab键有补全功能，容易把libphp4.a写成libmodphp4.a，但实际上libphp4.a是在make时编译的，程序先cp后ar，故若写成libmodphp4.a会出错。但是php-4.0b4pl1对汉字似乎不怎么支持，许多php在IE下成了乱码，在Netscape下表单变宽。改用php-4.0b2编译，但编译apache时老报错，有许多lib*.so找不着。用ldd命令看php-4.0b4pl1编译好的httpd需要什么链接文件：ldd /usr/local/apache/bin/httpd。这时会显示它链接的文件，这也是php-4.0b2所需的文件，把它们都拷到/lib下，加上PATH，再次编译，成功。对汉字也支持，不会出现乱码。（找不着的所需链接文件都在$INFORMIXDIR的lib/和lib/esql/下。原因：b2的编译文件做的不好，只会到/usr/lib和/lib下去找链接文件，希望php4正式版能抛弃b版的bug。）
