Problem with Drupal 7.0 installation – PHP extensions disabled

Ok, I found a way.

You can install a newer version of gcc (4.4.7) along the default version that comes with CentOS 5.9, using only the official packages of CentOS 5.9 and without overwriting the installation of gcc 4.1.2.

Here are the steps:

1.- Using yum, install the following packages (may be you can get along with fewer packages, but I tried installing these 3):

yum install gcc44.x86_64
yum install gcc44-c++.x86_64
yum install libstdc++-devel.x86_64

2.- Set the CC environment variable to point to the gcc44 compiler:

export CC=/usr/bin/gcc44

3.- Run the commands as indicated in the README file of the Python 3.3.2 tarball:

./configure
make
make test
sudo make install

Now, after the first "make" you should not see the error message related to the "_decimal" module. And "make test" should complete successfully.

4.- Unset the CC environment variable:

unset CC

And that's it.

I have the same laptop!

In the black GRUB menu that shows briefly, when highlighting the installation option or the "try Ubuntu" option:

• press the e key (for edit)
• where it says "splash ..." put "splash pci=noaer ..."
• press ctrl+x key combination to boot

After installation, open the Terminal application and type:

sudo dpkg-reconfigure grub-pc (or maybe grub-efi-amd64 ?)

There, press Enter and when it says "Linux default command line" you should add pci=noaer, so it should end up like this:

quiet splash pci=noaer

If you don't do that quickly after installation, your hard disk will get full because of log messages in /var/log/.
