    cannot find relevant LAPACK,BLAS libraries for octave 3.6.3

    hi,
    i installed octave 3.2.4 form the software center a few months ago but realised it was a very old version.so i decided to download the latest one (3.6.3) from the website.i have never compiled from the source before but learnt about it from a tutorial.

    i get an error after typing ./configure showing that LAPACK AND BLAS libraries are not found.i downloaded synaptic manager and downloaded the relevant libraries from the universe and multiverse category.but i'm still stuck with this error.

    how do i find out the exact name of the libraries needed?
    would trying with a less recent release avoid this error?
    thanks in advance

    did you get the -dev packages? (libblas-dev and/or liblapack-dev) iirc you will need those (not just the runtime libblas3gf or whatever) to actually build stuff

    hi steeldriver
    i have installed both of them (liblapack and libblac) it says they're static libraries (not sure what that means)but still no progress in compiling.

    here's what i get towards the end before the error shows up:
    Code:
    checking if sgemm_ is being linked in already... no
    checking for ATL_xerbla in -latlas... no
    checking for sgemm_ in -lblas... yes
    checking for dgemm_ in -ldgemm... no
    checking for sgemm_ in -lmkl... no
    checking for sgemm_ in -framework vecLib... no
    checking for sgemm_ in -lcxml... no
    checking for sgemm_ in -ldxml... no
    checking for sgemm_ in -lscs... no
    checking for sgemm_ in -lcomplib.sgimath... no
    checking for sgemm_ in -lblas... (cached) yes
    checking for sgemm_ in -lessl... no
    checking for sgemm_ in -lblas... (cached) yes
    checking whether LSAME is called correctly from Fortran... yes
    checking whether ISAMAX is called correctly from Fortran... yes
    checking whether SDOT is called correctly from Fortran... yes
    checking whether DDOT is called correctly from Fortran... yes
    checking whether CDOTU is called correctly from Fortran... yes
    checking whether ZDOTU is called correctly from Fortran... yes
    checking whether the integer size is correct... yes
    checking for cheev_... no
    checking for cheev_ in -llapack... no
    checking for cheev_ in -llapack_rs6k... no

    Hmm well from that output it seems to be finding libblas so I don't think the actual libraries are necessarily the problem

    What release / version of Ubuntu are you running? for the record, here is what works for me:

    Code:
    $ sudo apt-get install build-essential autoconf automake \
    gfortran libpcre3-dev libatlas-dev liblapack-dev libreadline6-dev \
    texinfo texlive-base
    IIRC it will configure and build without the tex packages, but you lose the inline help. This is on a 12.04 Server box so configure warns about being unable to find graphics:

    Code:
    configure: WARNING: I didn't find the necessary libraries to compile native
    configure: WARNING: graphics.  It isn't necessary to have native graphics,
    configure: WARNING: but you will need to have gnuplot installed or you won't
    configure: WARNING: be able to use any of Octave's plotting commands
    configure: WARNING:
    configure: WARNING: I didn't find gnuplot.  It isn't necessary to have gnuplot
    configure: WARNING: installed, but you won't be able to use any of Octave's
    configure: WARNING: plotting commands without it.
    and the 'make' fails right at the end when it tries to create a dvi, but the build essentially completes and basic command-line testing with ./run-octave works

    have a look in the config.log for more detailed error messages.

    you could also try to compile the octabe 3.6.3 package from ubuntu raring
    the configure runs through fine for me in precise with that package (I did not fully build it though)
    Code:
    pull-lp-source octave
    cd octave-*
    mk-build-deps -ir #requires devscripts and equivs
    debuild -us -uc
    you can also use the backportpackage script if you have a ppa or working pbuilder chroot

    i found out yestarday that the software center does have octave 3.6.3.it downloaded fine but i noticed that it was not able to plot 3d graphs and execute the eig() command instead it would close by itself.
    my ubuntu release is Release 12.04 (precise) desktop

    for example when i type sphere to plot a sphere i get:
    Code:
    octave: symbol lookup error: /usr/lib/liblapack.so.3gf: undefined symbol: ATL_idamax

    Re: cannot find relevant LAPACK,BLAS libraries for octave 3.6.3

    i think everything is working fine now.got an advice from someone.it seems that the ATLAS library was the culprit all along because of some configuration problem.according to him he suggested to completely remove the atlas library by typing the command
    'sudo apt-get purge libatlas3gf-base'
    3d plotting and matrix manipulations worked fine after that.
    hope there aren't anymore problems ahead
    thanks MadCow108 and steeldriver for your help.would have given up on octave otherwise
