<p>Hmmmm.&nbsp; I just tried your routine with gcc, (we don't have Sun's
compilers)
<br>% uname -a
<br>SunOS sagan 5.6 Generic_105181-09 sun4u sparc SUNW,Ultra-5_10
<br>% gcc -fPIC -c routine.c
<br>% /usr/ucb/ld -o t1.so -z text -G routine.o
<p>Under gcc, -fPIC and -fpic generate different code.&nbsp; Could that
be the
<br>problem?

Hello!
<p>Talking with my system manager, he told me that the right compilation
option is SunSolaris instead SusOs (in IDL Users Guide 4.0 they are considered
separately). In that way, I proceed with the SunSolaris options, described
in the IDL Users Guide:
<p><font size=-1>$ uname -a</font>
<br><font size=-1>SunOS mizar 5.5.1 Generic_103640-05 sun4u sparc SUNW,Ultra-Enterprise</font>
<p><font size=-1>$ cc -G -Kpic -c routine.c</font>
<br><font size=-1>$ ld -G -o routine.so routine.o</font><font size=-1></font>
<p>and no problem!
<p>Thanks all!
