Compiling Apache on a 64bit machine

perkiset

I am working on a few new boxes I just bought for the rack – they’re 64 bit dual Xeon

mac

hines – fast, strong, delightful. But when I went to build

Apache

I had trouble. My personal method is to create configure scripts that call configure with the options that want – and I name this file configure.p, so that no matter how long it’s been since I’ve worked on a

mac

hine, I can come back and see how I configured (that) application. My standard

Apache

config looks like this:

./configure
--enable-rewrite
--enable-ssl
--enable-proxy
--enable-so

It configured without complaint, but when I went to make, I received this error and termination:

/usr/lib/libexpat.so: could not read symbols: File in wrong format
collect2: ld returned 1 exit status
make[3]: *** [libaprutil-1.la] Error 1
make[3]: Leaving directory `/home/basel/temp/httpd-2.2.0/srclib/apr-util'
make[2]: *** [all-recursive] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/basel/temp/httpd-2.2.0/srclib'
make: *** [all-recursive] Error 1

After a big of searching, it turns out that

Apache

does not like to be compiled with 64 bit libraries by default. In addition to calling them out, you need to patch a bug in the configure script. Below is all the steps you need.

First off, we’ll assume that you are ready to compile

apache

2. You have a directory something like /usr/local/installs/httpd-2.2.3 where your compiling from. Step into the srclib directory. Copy the following code, and paste it into a new file in the srclib directory called patch64:

(You can also get it directly from the

apache

So at this point, you should have a file named patch64 in the directory /usr/local/installs/httpd-2.2.3/srclib. Of course, your directory structure might be different.

To execute the patch, enter this command:

patch –p0 < ./patch64

This will patch up the appropriate configuration files. Then you’ll need to rebuild the configuration. So delete the file [yourInstallDir]/srclib/apr-util/configure as well as the file [youInstallDir]/configure.

Then we’ll need to rebuild the configure scripts, so the from the root of the installation directory, do this: ./buildconf

That will rebuild everything necessary to configure for

Apache

.

Now we need to change our configuration file. My configure.p file now looks like this:

./configure
--enable-lib64
--libdir=/usr/lib64
--enable-rewrite
--enable-ssl
--enable-proxy
--enable-so

… this will have to assume that your lib64 is in /usr/lib64, which is the default for Fedora Core 6.

Now configure, make and make install and you’re good to go!

Hey Perk,

Mind if I ask why you compile a new

Apache

instead of just using "yum install httpd"? Performance? Anal retentiveness?

Inquiring minds want to know...... Applause

I've never been much for installers, RPMs etc. I often need

mac

hines that are a couple degrees off center, so it has just seemed easier to compile it exactly the way I want it. Got used to it, never quit.

And since it just never seems to fail that there's some little hiccup bullshit in an install, this gets me a little closer to it and *makes me feel* as thought I have more control. Applause

Another thing I've discovered from hand-building

Apache

2+

PHP

with funky configure options...

On RH, the build session will often grab 32-bit libraries <>without warning, even if the system is 64-bit, because links and library paths are often not correct. I wasted 2 days reproducing a funky Gentoo

Apache

2+

PHP

build on RH thanks to this kind of crap at last $job.

Carefully analyze what libraries are getting pulled in if you wind up with executables that don't get created, but with no apparent compiler failures.
