查看系统是多少位:
# getconf LONG_BIT
显示:
# 64
如果在64位系统上安装apache 正常情况下会报一下错误
/usr/lib/libexpat.so: could not read symbols: File in wrong format
原因是:编译的时候默认连接库是32位的库文件,所以需要手工指定64位库文件的位置
# cd /usr/local/src/
# tar -zxvf httpd-2.2.8.tar.gz
# cd httpd-2.2.8
# ./configure LDFLAGS="-L/usr/lib64 -L/lib64" --prefix=/usr/local/apache --enable-so --enable-expires --enable-rewrite --enable-headers --enable-deflate --enable-dav --enable-maintainer-mode
# vi ./srclib/apr-util/Makefile
修改
# APRUTIL_LIBS = -lsqlite3 -lexpat /usr/local/src/httpd-2.2.8/srclib/apr/libapr-1.la -luuid -lrt -lcrypt -lpthread -ldl
为
APRUTIL_LIBS = -lsqlite3 /usr/lib64/libexpat.la /usr/local/src/httpd-2.2.8/srclib/apr/libapr-1.la -luuid -lrt -lcrypt -lpthread -ldl
# make
# make install
安装jpeg 报错
make: ./libtool: Command not found
解决方案
由于libtool版本过低导致的,重新下载新版本的libtool以默认方式安装,执行以下命令:
./configure
make
make install
然后进入jpeg-6b的源码目录,然后执行以下步骤,切记!
cp /usr/share/libtool/config.sub .
cp /usr/share/libtool/config.guess .
./configure --prefix=/usr/local/jpeg6/ --enable-shared
--enable-static
