HTTPFS

Tiago Maluta — Thu, 01 Apr 2010 19:04:13 +0000

With FUSE it is possible to implement a fully functional filesystem in a userspace program, this allow great implementations like HTTPFS.

Before start don’t forget to load fuse module (i.e: modprobe fuse). Lets do an example, suppose you need check latest Gentoo ISO to catch some files.

$ mkdir ~/GentooISO
$ mkdir ~/GentooISO/minimal
$ httpfs http://216.165.129.135/releases/x86/autobuilds/\
current-iso/install-x86-minimal-20100216.iso GentooISO/
$ cd ~/GentooISO
$ mount -o ro,loop install-x86-minimal-20100216.iso  minimal

Note that I used 216.165.129.135 instead distfiles.gentoo.org to avoid http error.

HEAD (read) failed with Status 302

You coud see the corret IP using, for example, wget.

Try it! It’s really fast.

Problems updating intltool on Gentoo

If you are experiencing some problems on updating dev-util/intltool on Gentoo, this is the message that is shown:

checking for perl… /usr/bin/perl
checking for perl >= 5.8.1… 5.10.1
checking for XML::Parser… configure: error: XML::Parser perl module is required for intltool

In other emerges if its failing on some perl module check during ./configure, its maybe because dev-lang/perl was updated an its modules weren’t compiled against the new one, on my case I just runned the command:

perl-cleaner --all

It will rebuild all your modules against your new perl, then you can re-emerge dev-util/intltool.

Arduino Gentoo Install

If you are reading this post it’s probably that you already checked other resources and had some problem to build avr-g++ using crossdev utility.

crossdev -t avr -s4

Note that cpp compiler wasn’t created.

# qlist cross-avr/gcc | grep bin
/usr/i686-pc-linux-gnu/avr/gcc-bin/4.4.1/avr-gccbug
/usr/i686-pc-linux-gnu/avr/gcc-bin/4.4.1/avr-gcov
/usr/i686-pc-linux-gnu/avr/gcc-bin/4.4.1/avr-cpp
/usr/i686-pc-linux-gnu/avr/gcc-bin/4.4.1/avr-gcc
/usr/i686-pc-linux-gnu/avr/gcc-bin/4.4.1/avr-gcc-4.4.1

The problem is easy to fix. Simple edit /etc/portage/package.use/cross-avr changing ‘nocxx‘ to ‘-nocxx‘ and run emerge again.

emerge cross-avr/gcc cross-avr/avr-libc dev-embedded/avrdude

I’m using AVR toolchain with Arduino 0017 flashing by USB.
