Re: How I do link arpack to eigs.cc and svd.cc on the Ubuntu build?

[Jacob Dawid]

Tatsuro,

I compiled and installed it, too, here. From what I understand is you have to do the following:

Instead of:

LIB='-larpack'

try

LIB='-L/usr/local/lib -larpack'

Then open a terminal and do

gksudo gedit /etc/ld.so.conf

and add the line

/usr/local/lib

Save the file and do

sudo ldconfig

Cheers,

Jacob

Libraries have been installed in:
   /usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

Hello

After 'make' of arpack, I did
$ sudo make install

After that,

ls /usr/local/lib
libarpack.a   libarpack.so    libarpack.so.2.0.0  octave     python2.7
libarpack.la  libarpack.so.2  ocaml               pkgconfig

Have to I add /usr/local/lib to LD_LIBRARY_PATH and/or LD_RUN_PATH?

Regards

Tatsuro
