Hi,
I finally found the solution with gcc. It does not work with CC but I
am suspicious that my intallation is not correct. I used IDL 5.4 and
It turns out that it work at 64bits so it needs the libraries compiled
at 64bits. The last version of gcc gives you this choice with the
compilation option of -m64. I did not have this version but the
problem can be solved if we launched idl in 32bit mode, this could be
achieved with idlde -32 & idl -32, and then it works fine.
Just you know in case someone comes across with the same problem.
Thanks for your help folks.
