Re: [libcvd-members] Building libcvd

[Svancara, Randall]

Since it will most likely be weeks before anyone replies to this, I will go ahead and answer my own post.  Basically the problem is that the LAPACK checks in the configure file are broken.  The way they are configured “MAY” work with the AMD version LAPACK, however, to use something like ATLAS, you need to change all occurrences of –llapack to -lgfortran -llapack -lf77blas -lcblas –latlas.  And then of course, you need to provide the extra paths to the configure when you do the build.

 

LDFLAGS="-L/home/software/atlas_gcc/lib -L/home/software/ffmpeg_gcc/lib -L/home/software/gvars3/lib" CPPFLAGS="-I /home/software/ffmpeg_gcc/includes -I/home/software/TooN-2.0/include -I/home/software/gvars3/includes -I/home/software/atlas_gcc/include" ./configure  --prefix=/home/software/libcvd  --without-dc1394v2 --without-dc1394v1 --without-videodisplay

 

If I have time, I will submit my changes as a patch.

Subject: [libcvd-members] Building libcvd

 

Hi,

I am trying to build libcvd and I am experiencing difficulty with the software finding lapack and ffmpeg.  I have built the “reference” version of lapack, which I know is slow compared to ATLAS or MKL or AMCL.  I am using Intel platform, and I would prefer to use MKL, but for now, I just want to build the software with the reference LAPACK and ffmpeg. 

 

Ffmeg is installed into /home/software/ffmpeg_gcc and LAPACK is installed into /home/software/lapack_reference.  When I run ./configure, I use the following command:

 

LDFLAGS="-L/home/software/lapack_reference/lib -L/home/software/ffmpeg_gcc/lib -L/home/software/gvars3/lib" CPPFLAGS="-I /home/software/ffmpeg_gcc/includes -I/home/software/TooN-2.0/include -I/home/software/gvars3/includes -I/home/software/lapack_reference/includes" ./configure  --prefix=/home/software/libcvd  --without-dc1394v2 --without-dc1394v1

Options:

Missing options for linux-gnu:

dc1394v1 dc1394v2 ffmpeg lapack

 

Dodgy things:

------------------SNIP--------------------------------------

 

LAPACK ffmpeg are never found at all.  I even attempted to install the antiquated ffmpeg libraries that come with RHEL 5.x, and the build still fails to find ffmpeg.
