I'm having trouble getting rid of my depsolving errors, and I've been left to figure this one out on my own. It all started when I wanted to upgrade from PHP 5.2 to PHP 5.3 (heaven forbid), and I was told that we have all kinds of dependency mess because we have multiple PHP packages, and no one else is using it, so if I wanted it, I'd have to do it myself.

I managed to figure out how to get PHP 5.3 installed, but only by removing all previous versions of PHP and doing a fresh install. Now "my" (someone departed's) code is relying on PHPExcel, which relies on php-pecl-zip, which I apparently don't have. Here's some of what I've tried:

Install with PECL

# pecl install zip   
No releases available for package "pecl.php.net/zip"  
install failed

Pretty sure this is because our machines have very strict rules about who they can talk to. So I can't access the package via PECL.

Install with YUM

# yum install php-pecl-zip
Dependencies Resolved

================================================================================
 Package             Arch          Version                 Repository      Size

Installing:

Installing for dependencies:
 php-common          x86_64        5.1.6-24.el5_4.5        updates        152 k

Why does it want a PHP version 5.1 when I have 5.3?
Of course, if I let it go, it barfs:

Transaction Check Error:
  file /etc/php.ini from install of php-common-5.1.6-24.el5_4.5.x86_64 conflicts with file from package php-5.3.24-7.x86_64

And just to verify:

# yum list php
Installed Packages
php.x86_64                          5.3.24-7                           installed

Can we get around it? A few attempts follow

# yum install php-pecl-zip --skip-broken
Transaction Check Error:
  file /etc/php.ini from install of php-common-5.1.6-24.el5_4.5.x86_64 conflicts with file from package php-5.3.24-7.x86_64

Skip broken does nothing

# yum install php-pecl-zip --skip-broken --exclude=php-common
php-pecl-zip-1.8.10-2.el5.x86_64 from epel has depsolving problems
  --> Missing Dependency: php-api = 20041225 is needed by package php-pecl-zip-1.8.10-2.el5.x86_64 (epel)
Packages skipped because of dependency problems:
    php-pecl-zip-1.8.10-2.el5.x86_64 from epel

Excluding the package doesn't help

# yum install php-pecl-zip --skip-broken --exclude=php-common --exclude=php-api
php-pecl-zip-1.8.10-2.el5.x86_64 from epel has depsolving problems
  --> Missing Dependency: php-api = 20041225 is needed by package php-pecl-zip-1.8.10-2.el5.x86_64 (epel)

Packages skipped because of dependency problems:
    php-pecl-zip-1.8.10-2.el5.x86_64 from epel

Can we install an underlying dependency?

# yum install php-api
Package php-common is obsoleted by lift-php, trying to install lift-php-5.3.24-10.x86_64 instead
Resolving Dependencies
--> Running transaction check
---> Package lift-php.x86_64 0:5.3.24-10 set to be updated

--> Finished Dependency Resolution
lift-php-5.3.24-10.x86_64 from COMPANY-codex-released has depsolving problems
  --> lift-php conflicts with php
Error: lift-php conflicts with php

This is where the dependency loop starts. You'll notice we have COMPANY-codex-released repos that are in play.

# yum install php-api --skip-broken

Exclude lift-php?

# yum install php-api --exclude=lift-php

No.

So I think YUM is in a dependency loop.

I also did some silly stuff installing a new EPEL repo, but then yum couldn't resolve any mirrors, so I had to uninstall it. I'm not sure those were symmetric actions, either.

The first time I did this I also had to do yum install autoconf

Install downloaded file with PEAR
So I went to http://pecl.php.net/package/zip and got a download, scp'd it up to my machine.

# pear install -O /home/produser/zip-1.12.4.tgz

So those first couple of warnings are actually new. Never seen them before just now. Maybe that's a new lead.

(EDIT: I think this startup error is because I went into /etc/php.ini and uncommented extension=php_zip.dll. When I comment that line back out, it goes away.)

But zlib is there:

# yum install zlib

Nothing to do  

EDIT:

configure: error: Can not find zlib headers under "/usr/share/doc/zlib-1.2.3/README"

So even though the package manager says that's the location of zlib, and I've started compiling the thing by hand, it still doesn't work.

Reinstall zlib? Seems to execute fine

# yum reinstall zlib

Complete!

EDIT
Thanks to these guys: http://ubuntuforums.org/showthread.php?t=692704 I realized I needed to install zlib-devel instead. And just for good measure, to remove one of my warnings, I also did re2c.

# yum install zlib-devel

# pear install zip-1.12.4.tgz

Now these guys (http://www.linuxquestions.org/questions/linux-software-2/install-zip-extension-using-pear-840755/) say

# yum install pcre-devel

which doesn't quite work for me, but

# yum install COMPANY-pcre-devel

works fine

# pear install zip-1.12.4.tgz 

same make error.

http://www.linuxquestions.org/questions/red-hat-31/rpm-error-cannot-create-sourcedir-165733/ http://rpm.pbone.net/index.php3/stat/26/dist/55/size/571124/name/pcre-6.6-2.el5_1.7.src.rpm

# yum install rpm-build
# rpmbuild --rebuild pcre-6.6-2.el5_1.7.src.rpm  # manually downloaded this exact version of the rpm
TONS of output, but the tests all passed, so it seems to have worked...
# cd /usr/src/redhat/RPMS/x86_64
# rpm -ivh pcre-devel-6.6-2.7.x86_64.rpm

                        6.6-2.7                   installed

BOOM! Another dependency down.

  • Couldn't access the pecl servers from my server, so download tarball from http://pecl.php.net/package/zip and manually put it on server
  • yum install zlib-devel
  • yum install pcre-devel didn't work for me, so I had to go to http://rpm.pbone.net/index.php3/stat/26/dist/55/size/571124/name/pcre-6.6-2.el5_1.7.src.rpm to get the exact RPM version that was listed in my depsolving error.
  • yum install rpm-build
  • scp pcre-6.6-2.el5_1.7.src.rpm to my server
  • rpmbuild --rebuild pcre-6.6-2.el5_1.7.src.rpm
  • cd /usr/src/redhat/RPMS/x86_64
  • rpm -ivh pcre-devel-6.6-2.7.x86_64.rpm
  • yum list installed | grep pcre to see that it worked
  • cd dir/to/manually/uploaded/zip.tgz
  • pear install zip-1.12.4.tgz
  • vi /etc/php.ini
  • add extension=zip.so to php.ini
