How to compile correctly?

Question

linux

Cross compile apache httpd with arm-none-linux-gnueabi
Compiled prce, apr, apr-lib, go to apache compilation and get this error
/usr/local/apache/httpd/apr/build-1/libtool --silent - -mode=link gcc -std=gnu99 -g -O2 -L/usr/local/apache/httpd/xml/lib -lpthread -o htpasswd htpasswd.lo /usr/local/apache/httpd/apr/lib/libaprutil- 1.la -lexpat /usr/local/apache/httpd/apr/lib/libapr-1.la -lrt -lcrypt -ldl -lcrypt
/usr/local/apache/httpd/xml/lib/libexpat.so: could not read symbols: File in wrong format
And I can't figure out what's wrong. No matter what I do, I always get this error.
I work under ubuntu 64bit

Answer 1

libexpat.so is most likely compiled for x86. You need to look at which compiler the system calls during assembly and dig towards errors in the Makefile, or variables not passed to build scripts.

Answer 2

/usr/local/apache/httpd/xml/lib/libexpat.so is a dynamic library, and you are linking it as a static one.
gcc -L /usr/local/apache/httpd/xml/lib -lexpat *.o
