(Solved) Problem with fontconfig breaking php-gd

[paulcrawford]

I use php-gd to support JPGraph which presently advises that gd is not available. Indeed looking at php info gd is not loaded, although requested in php.ini.

Looking the php error log, the reason that gd is not loaded is that libfontconfig is empty:

$this->bbcode_second_pass_code('', '[15-Aug-2016 02:41:31 UTC] PHP Warning: PHP Startup: Unable to load dynamic library '/usr/lib/php/modules/gd.so' - /usr/lib/libfontconfig.so.1: file too short in Unknown on line 0
')

Looking at the user library it is clear that libfontconfig is empty:

$this->bbcode_second_pass_code('', '# ls -l /usr/lib/
lrwxrwxrwx 1 root root 22 Aug 6 11:27 libfontconfig.so -> libfontconfig.so.1.9.2
lrwxrwxrwx 1 root root 22 Aug 6 11:27 libfontconfig.so.1 -> libfontconfig.so.1.9.2
-rwxr-xr-x 1 root root 0 Aug 6 11:27 libfontconfig.so.1.9.2
')

Looking at what is installed and trying to reinstall fontconfig shows that the package is corrupt:

$this->bbcode_second_pass_code('', '# pacman -Q fontconfig
fontconfig 2.12.1-3
[root@no php]# pacman -S fontconfig
warning: fontconfig-2.12.1-3 is up to date -- reinstalling

looking for conflicting packages...

')

This is interesting as fontconfig-2.12.1-3 was installed at the same time as the uboot-odroid-c2-2015.01-10 that I had problems with last week and made my C2 unbootable (although it is working again now). Looking at the upgrade of fontconfig at that time there was no indication of any corruption but now there is.

Will there be a fontconfig-2.12.1-4-aarch64 soon to clean this up so I can get gd running again?

Thanks,

Paul

1) please checked your disk
2) Ensure you have have not modified the CARCH of pacman.conf (I hope not, but hey)
3) Ensure that your package index is up to date.

As you can see from the pacman output, it was re-installing the package from your local package cache, and somehow that pkg.tar.xz has become problematic. Having removed it now, it should re-download from the mirrors

$this->bbcode_second_pass_quote('', '1')) please checked your disk

fsck

[paulcrawford]

I took the eMMC card and put it in a Linux machine, unmounted it and ran fsck:

$this->bbcode_second_pass_code('', '# fsck /dev/sdb1
fsck from util-linux 2.20.1
e2fsck 1.42.9 (4-Feb-2014)
/dev/sdb1: clean, 46819/477664 files, 807791/1908480 blocks
')

It seems that there is no problem with the card.

What can I try next?

[WarheadsSE]

Interesting. Then you've got an actual problem with the write-cache at some point.

My suggestion is to use --force on that particular package, and only that package.

You might want to search the rest of your system non-symlink for *.so files, in case anything else has hit this problem.

[paulcrawford]

I did as you suggested using --force to install the fontconfig package. Then I reinstalled gd and php-gd (without --force) and rebooted. Finally JPGraph is working again!

I am also starting to figure out how to do the search for other possibly empty .so files. It will be a good experience to learn how to do that.

Thank you so much for your patience.
