fixed, thanks

Hi, I have a problem to build this package with `aura` due to the backslash used to split the `depends` array. So I asked the mailing-list [1] to know if this is an `aura` bug or if the PKGBUILD musts not contain the backslash. It seems that removing [2] it is the right way. Could you remove it? That will make my updates simpler :) Thanks, Fabien [1] https://mailman.archlinux.org/pipermail/aur-general/2013-November/025993.html [2] https://mailman.archlinux.org/pipermail/aur-general/2013-November/025994.html

This is a bug in makepkg. Try roadrunner's suggestion. If that fails, clone the repo maunally, cd ito it and run bootstrap. After that cd into $startdir and run makepkg.

can't find /tmp/octave-hg/octave/gnulib-hg it failed instandly

Thanks for hint. Looks like there is a bug in hg which does only clone the subrepos if there is a working copy in the main repo. Here is the set of commands that worked for me: # fails due to bug in hg makepkg -i # Make a working copy in the primary repo. This also fetches all subrepos. cd octave hg update cd .. # Run makepkg again, this time the cloning should work. makepkg -i

A workaround is to clone the repo manually once, and to use the PKGBUILD after that. The old behavoiur did not work for me anymore with pacman 4.1.1.

Hi all, i have tried building with the current PKGBUILD and get the error message: ==> Extracting sources... -> Creating working copy of octave hg repo... updating to branch default abort: repository octave/gnulib-hg not found! ==> ERROR: Failure while creating working copy of octave hg repo Aborting... Looks like the handling of the subrepos (gnulib-hg is a subrepo included the main octave repo) still does not work. Erik

Some additional modifications for refactored llvm-Code were added.

Hi all. After days of struggling with this, I was finally able to successfully build Octave using Intel ICC/IFORT and MKL libraries. This link claims that he found an improvement in performance of 100x for multiplication of 2 - 5000x5000 matrices, compared to standard gcc with no performance BLAS/LAPACK libraries (such as ATLAS or MKL) http://qc.uoregon.edu/octave-build-notes.html I found somewhat similar results, although not quite as drastic---my speedup was ONLY ~50x (that simple benchmark ran in 7.5s for me) This is my first successful attempt ever trying to do this. This may not be the most graceful modification and there may be some extraneous stuff here. However, it worked successfully for me (finally...) and I thought that I would share it, so that others might benefit as I did. My PKGBUILD can be found here: http://pastebin.com/8rdBkDtw There are 3 major changes which I made to the PKGBUILD file: 1) Compiler flags and environment variables 2) Added additional flags to the ./configure script 3) Modified stdio.h under libgnu folder to address an error. Please also note the following: - There are some compiler flags that are particular for my CPU. You might need to change -axX -xX -mtune -march flags to suit your system - I've tried to enable all optimizations. The build was very slow. I have 2 x Xeon 5160 (Dual core, 3.0GHz ) CPUs in this box and it took 1:23:12.17 to build. Removing the -ip -ipo flags would speed this up significantly. I don't know how it would affect the runtime performance - I have disabled the GUI. Revise the last flag on ./configure line to suit your requirements. I hope that you all find this helpful. I'd love to hear any feedback. Shmuel
