Git from source, no sudo

logo2x

Need to update an old Git on RHEL 6.x without sudo, here are the instructions. Testing on CentOS VM.  Assume some old versions of the dependencies have already been installed on the target system.  Starting versions in VM environment:

Dependency Version
Automake 1.11.1
M4 1.4.13
Autoconf 2.63
curl 7.19.7
zlib assume not installed
openssl 1.0.1e-fips
libtool? – Might be required for expat build from source? assume not installed
expat assume not installed
libiconv really required?  Try without first
  • Without sudo, must build zlib from source (easy)
  • Same for expat
  • expat demands an updated version of Autoconf (because of “couldn’t open directory ‘m4′” error, or perhaps creating an empty “m4” subdir would’ve worked), which in turn recommends M4 v1.4.14 or later.
  • In building expat, get multiple “error: possibly undefined macro: AC_LIBTOOL_*” messages. From this guidance, need to install libtool

GCC from source, no sudo

gccegg-65

Need a significant upgrade on a GCC/GNAT toolset in an environment without sudo permissions. Starting from this guidance. Starting versions (here’s a useful way to check):

Tool Version
GCC 4.7.4
G++ 4.7.4
GNU Make 3.8.1
GNU Bison 2.4.1
Flex 2.5.35
GNU GMP 4.3.1-7 (via rpm -qa)
GNU MPFR 2.4.1-6 (via rpm -qa)
GNU MPC not present?

First impressions of Ubuntu 12.10 (Quantal Quetzal)

For previous Ubuntu versions, I had used the Alternate CD .iso image installer in order to get disk encryption for my laptop. As Marius Nestor correctly points out, there’s no Alternate CD with 12.10 – this feature is now wrapped in the main installer. I discovered all this after my first install using the “Something else” option shown Marius’ post, which didn’t offer the disk encryption option (or perhaps I missed it).

Ubuntu 12.10 (Quantal Quetzal)

There’s no GUI method of turning off “Guest Session” login, but it can be easily done in config.

The launcher is much improved and rearranging icons is finally a user-friendly experience.

I don’t like advertised content in the Dash. I’m betting the community will shout that idea down. But in the meantime, I think I saw a way to turn them off along with Twitter/Facebook/Gmail/etc. integrations.

Overall, my early-2008 vintage ZaReason 2GB BigLap had been ready for a fresh install. Now it’s running 12.10 just fine, thank you very much. It’s a worthy upgrade.

Multiple Monitors in Ubuntu

Update, 2011-06-01:  grumble, this is broken again in Ubuntu 11.04.  I currently don’t have a solution, and I’m just working without my external monitor.  Not goodness.

I recently updated all my ZaReason boxen to Ubuntu 10.04, and managing multiple monitors in this update is easier than it used to be. Continue reading

Linux-friendly audiobook mp3 downloads

(UPDATE 2009-09-23): LearnOutLoud.com has outstanding technical support if you ever have trouble with your downloads.

Today I found my Linux audiobook solution. LearnOutLoud.com allows paying for and downloading audiobooks in MP3 format. No annoying proprietary client-side app required. Books purchased in the past are available for later re-download from my LearnOutLoud account if I need them. Wow, it’s so nice not to be treated like a common criminal! Thanks very much, LearnOutLoud.
