Below is a script and response files for an extended,/*failed*/, gcc
execution on my machine Ubuntu 14.04
For the untrusting (smart ones) here is the script. Google blocked
the executable script so I will have to dodge that if anybody wants a copy.
---------------------------
#!/bin/bash
# The following might have to be changed
cd /opt/gsl-1.99.90/doc/examples
# Verbose record of compiler in interp2d.lst
gcc -v -g -Wall -o interp2d interp2d.c -lgsl -lgslcblas -lm &>interp2d.lst
#
# You will notice that everything looks okay, to me, in interp2d_locate.lst
locate interp2d &> interp2d_locate.lst
---------------------------------------------------------------------
It's been some time since I debugged gcc output so I just glanced at
interp2d.lst and found nothing strange. All of the dates looked okay;
Oct 31 1015 except for the present .lst files. If you want a deeper
look into the file linkages/contents let me know.
