Error when compiling apache, “Undefined symbols:Undefined symbols:”_apr_dir_read$INODE64“…ld: symbol(s) not found”

问题

I am trying to compile Apache. I did download the latest version of the sourcecode (2.2.17). This is what I do:

> sudo ./configure --prefix=/usr/local/apache2 --with-included-apr --enable-mods-shared=all --enable-module=so

> sudo make

and when doing that I get:

/Users/Niklas/Development/apache/httpd-2.2.17/srclib/apr/libtool --silent --mode=link gcc -g -O2        -o httpd  modules.lo buildmark.o -export-dynamic server/libmain.la modules/http/libmod_http.la modules/mappers/libmod_so.la server/mpm/prefork/libprefork.la os/unix/libos.la  /Users/Niklas/Development/apache/httpd-2.2.17/srclib/pcre/libpcre.la /Users/Niklas/Development/apache/httpd-2.2.17/srclib/apr-util/libaprutil-1.la -lexpat -liconv /Users/Niklas/Development/apache/httpd-2.2.17/srclib/apr/libapr-1.la -lpthread

What am I doing wrong?

I am using OSX but I guess that shouldn't matter?

I have been struggling with this for several days so I hope someone can point me in the rigth direction?

Thank you in advnace!

回答1:

You're trying to build on OSX? Do you have the dev tools installed?

Your compile definitely failed which is why it's not working. You would probably be better off looking for precompiled packages to do what you need to do. At the very least you would be better off looking for guides to building apache on OSX.

Apache also has a way to compile install just the modules you're trying to add on using a utility called apxs2. OSX should have Apache installed already and I can't imagine they wouldn't have enabled that in their build.

Granted I don't know for sure but a good place to start would be to Google install mod_dbd on OSX

Hope that helps!

I had a similar problem while building httpd 2.4.2 on Mac OS X, first download the latest APR from here http://apr.apache.org/ then compile and install it somewhere, then reconfigure httpd like this

./configure --with-apr=/Users/youruser/where/you/installed/apr
