With the release of OS X 10.10 Yosemite, Apple upgraded its Apache server to version 2.4.
At release time, mod_perl 2.0.8 was incompatible with Apache 2.4, and mod_perl 2.0.9 had not yet been officially released (more info).
So, Apache was included without mod_perl.
I work locally on a web site using perl and need to install mod_perl.
I'm an experienced programmer, but I have never done anything like this before and have only my main machine to work on. I don't mind spending some time to figure this out, but I can't afford to bork my local server.
How does one install mod_perl on OS X Yosemite?
Sub-questions:
- which version should I install?
- do I download it to the install location or elsewhere?
- where do I install it?
- are there other dependencies that need to be installed beforehand?
- do I have to re-create the apache install or is the mod_perl installation self-contained?
I'm experienced in bash and very comfortable using Terminal.
mod_perl 2.0.8 (latest stable) won't cut it--it's unaware of the deprecation of MPM_NAME in apache 2.4.x Download the latest dev via svn:
svn checkout https://svn.apache.org/repos/asf/perl/modperl/trunk/ mod_perl-2.0
The Changes file lists this version as 2.0.9-dev
Xcode 6.01 won't cut it--it's apache headers will make mod_perl think you're running apache 2.2.26; get Xcode 6.1 (released Oct 20).
Makefile.PL will still have trouble finding ap_release.h (to get your apache version). It's here:
/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/apache2/ap_release.h
Makefile.PL will look by default in /usr/include/apache2. It will also look for apr headers in /usr/include/apr-1 because the Yosemite-included /usr/bin/apr-1-config will tell it that's where they are (they're actually in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/apr-1 )
/usr/bin/apr-1-config --includedir
/usr/include/apr-1
I tried setting env vars MP_AP_PREFIX and MP_APR_CONFIG appropriately, but those values seemed to be ignored. So I made things easier on myself:
$ sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/apache2 /usr/include/apache2
$ sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/apr-1 /usr/include/apr-1
(thanks to Sean Coyne) Per Jason A. Crome's blog post "llvm/clang on OS X defaults to C99, but mod_perl expects the 89 "standard"
$ perl Makefile.PL MP_CCOPTS=-std=gnu89; make ; sudo make install
The LoadModule line for mod_perl has been removed from Yosemite's /etc/apache2/httpd.conf file.
Add
LoadModule perl_module libexec/apache2/mod_perl.so
to the module section of /etc/apache2/httpd.conf
Extra screwing around required in El Capitan!
In El Capitan, Apple prevents users from writing to anywhere under /usr/ except /usr/local/
Referencing Dan Deal's and Andrew Swift's answers above, and assuming you have Xcode 7 and the El Capitan (10.11) SDK installed:
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/apache2 /usr/local/include/apache2
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.11.sdk/usr/include/apr-1 /usr/local/include/apr-1
Will soft-link the Xcode headers to /usr/local/include.
Next, we need to tell Makefile.PL where to find the headers (since it assumes /usr/include by default).
sudo cp /usr/sbin/apxs /usr/local/bin
to make a copy of the APXS tool which Makefile.PL uses to locate the apache headers. Now edit it:
sudo vi /usr/local/bin/apxs (or)
sudo nano /usr/local/bin/apxs
locate the line which says:
my $prefix = get_vars("prefix");
and replace it with:
my $prefix = "/usr/local";
Ensure that /usr/local/bin is in your path before /usr/sbin, so that it picks up the one you just modified:
export PATH=/usr/local/bin:$PATH
Now you can go ahead and build mod_perl:
perl Makefile.PL MP_CCOPTS=-std=gnu89; make ; sudo make install
Finally, when you edit your httpd.conf, you need to explicitly pass the full path to mod_perl.so, as it's not in the directory that apache expects to find it:
LoadModule perl_module /usr/local/libexec/apache2/mod_perl.so
This is a simplified version of Dan Deal's answer, with a few notes for less experienced developers.
You'll need to install Xcode 6.1 from the Mac App Store. Xcode is suite of tools developed by Apple for developing iOS and OS X software. It takes up almost 6gb but can be deleted after this installation.
Start Xcode once to agree to Apple's terms.
In Terminal, change to any temporary directory then download mod_perl 2.0.9-dev: (Caution - the 'any temporary directory' must be on your root volume and must not have any space characters in the directory name; otherwise the make scripts will fail later on)
svn checkout https://svn.apache.org/repos/asf/perl/modperl/trunk/ mod_perl-2.0
Change to the newly created mod_perl directory:
cd mod_perl-2.0
Tell the installer where to look for parts:
/usr/bin/apr-1-config --includedir /usr/include/apr-1
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/apache2 /usr/include/apache2
sudo ln -s /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.10.sdk/usr/include/apr-1 /usr/include/apr-1
(ln -s makes a symbolic link, and the apr-1-config program is used to retrieve information about the apr library, and is typically used to compile and link against the library.)
(Caution - on some Yosemite installations the /usr/include directory does not exist; you may have to create it by cd /usr;mkdir include)
Make mod_perl:
perl Makefile.PL MP_CCOPTS=-std=gnu89; make ; sudo make install
Delete the temporary folder mod_perl-2.0.
Tell apache to include mod_perl in the apache httpd.conf:
sudo vi /etc/apache2/httpd.conf (or)
sudo nano /etc/apache2/httpd.conf
Add the following line at the end of the list of includes, near line 170:
LoadModule perl_module libexec/apache2/mod_perl.so
Save, quit, and restart apache:
sudo apachectl restart
Thanks for all the pointers above. Here's a solution/receipe, building from source without symbolic linking to odd files within Xcode, and avoiding the 'Expected in: flat namespace' error.
(edit:) To my big surprise the httpd that Apple provides (2.4.16) is now capable of running with my mod_perl!
0 Xcode 7.3 (beta), and command line utils, OS X 10.11.3 El Capitan
1 install perl, with threads:
perlbrew install -f -Dusethreads perl-stable;
I put perl into /usr/local/perl5/
2 get apr-1.5.2
3 get apr-util-1.5.4
4 get pcre-8.38 (./configure --prefix=/usr/local/pcre; make; make install)
5 get httpd-2.4.9
6 COPY (cp -r -p) the dirs apr-1.5.2 and apr-util-1.5.4 to httpd-2.4.9/srclib/ as 'apr' and 'apr-util' respectively, to be able to use --with-included-apr when building httpd.
7 cd httpd-2.4.9

export CPP=/usr/bin/cpp
