# ld -V

GNU ld version 2.15.92.0.2 20040927

Supported emulations:

elf_x86_64

elf_i386

i386linux

#ld -m elf_i386

Along with the -m32 flag in gcc, you may need to include the -melf_i386 flag for ld to properly link the 32bit object

files to the 32bit libraries if you have both the 32bit and 64bit libraries.

make libdir=/usr/lib64

make libdir=/usr/lib

的系统上编译时需要链接64位的库文件，而/usr/lib/libexpat.so是32位的ELF格式，所以格式不对。在configure的时候添加

LDFLAGS="-L/usr/lib64 -L/lib64" 选项即可

./configure CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 FCFLAGS=-m32 LDFLAGS=-melf_i386 --prefix=/root/j131/testhttpd/apache-32bit

./configure CFLAGS=-m32 CXXFLAGS=-m32 FFLAGS=-m32 FCFLAGS=-m32 LDFLAGS="-L/usr/lib" --prefix=/root/j131/testhttpd/apache-32bit

修改apr-config

vi /usr/local/apache2/bin/apr-config

修改LDFLAGS=" " 为 LDFLAGS="-lz"
