Q: Proper location for dynamically-loadable modules

[chrislee]

I am developing an application which loads most of its code at
run-time from a set of shared-libraries.  These libraries are code
modules which are not generally usable from other applications.  Under
Debian's file-system standards, can I put these shared libraries in a
subdirectory of /usr/local/lib, say /usr/local/lib//*.so (a
script would set LD_LIBRARY_PATH to include this path, then call the
executable), or should the libraries be in /usr/local/lib?

First, convert the jpeg to an encapsulated postscript file. xv can do

Then, before the \begin{document} statement in the LaTeX file, insert
the statement \usepackage{psfig}.  In your document body, do something
like this:

  \psfig{file=image-name.epsi}
 or
  \psfig{width=2.5in,file=image-name.epsi}

To insert the image.  You can use the epsf package too, if you prefer.

I am not sure what this means.  cfortran.h is a header file for
exporting Fortran functions to C.  Did you use this to call
BLAS/Lapack from C and get the wrong answer when using large
matrices?  If this is the case, I would definitely like to know what
went wrong (what size matrix, what BLAS/Lapack functions, what error
mode).  You can use cpp to see what cfortran.h does for your
particular function declaration.

I use the cfortran header file from this location
ftp://zebra.desy.de/cfortan 
to build prototypes for BLAS and Lapack functions.

I have a wrapper library (CHRLIB) for much of BLAS and some of Lapack
at this location:
 http://www.cs.cmu.edu/~chrislee/chrlib/
There is also a Guile wrapper for this library (G-CHRLIB) at the same
location.

Information about BLAS and Lapack can be found here:
 http://www.psc.edu/general/software/packages/blas/blas.html
 http://www.psc.edu/general/software/packages/lapack/lapack.html
