为CentOS 6.5构建httpd-2.4.7 RPM时找不到库`/usr/lib64/libexpat.la'

Question

I am following up the instruction from http://httpd.apache.org/docs/2.4/platform/rpm.html to build httpd-2.4.7 RPM for CentOS6.5. But I got the following errors - cannot find the library `/usr/lib64/libexpat.la'.

rpmbuild -tb httpd-2.4.7.tar.bz2

..... /usr/lib64/apr-1/build/libtool --silent --mode=link gcc -std=gnu99 -pthread -O2 -g -pie -o htpasswd htpasswd.lo passwd_common.lo /usr/lib64/libaprutil-1.la -ldb-4.3 -lexpat -ldb-4.3 /usr/lib64/libapr-1.la -lpthread -ldl -lcrypt

I ran yum search libexpat , the package has been installed.

Anyone knows how to solve this issue. Thanks in advance.

Answer 1

The INSTALL doc states that you can:

./configure --with-included-apr

to use APR and APR-util libraries which include libexpat.la and come with httpd.

Answer 2

A .la file is for libtool to know how to link a library. It's probably in expat-devel , and should be added to the .spec file as a BuildRequires .

Answer 3

Install apr and apr-util before installing apache.

libexpat.la comes along with the source code of apr-util.

Try copying source code directory of apr and apr-util into srclib directory of apache and use ./configure --with-included-apr . This solved my issue.

cp -r /path/of/apr /path/of/apache/srclib/

cp -r /path/of/apr-util /path/of/apache/srclib/

./configure --with-included-apr
