Re: FreeWRL plugin, libtool problem

[Michel Briand]

Hi all,

I've a grave problem : when I build my Debian package the libtool
install mode was not called. In the resulting package
the /usr/bin/freewrl is not the real binary :

/usr/bin/freewrl: error: `/usr/bin/.libs/freewrl' does not exist
This script is just a wrapper for freewrl.
See the libtool documentation for more information.

Any idea ?

Michel
