Hi,


I finally succeeded in understanding what happens on Debian/Ubuntu.

First there was a bug of mine which included the version number inside 
the package name when defining dependencies. Bad idea... Now it is fixed.

But now comes how Debian compares version number (I will call that 
"Debian cretinism" now).

In the Gambas packager, you can name your package with the major & minor 
version number (MyLib-0.0) or with the major, the minor and the release 
number (MyLib-0.0.1). The first one is the default.

Debian adds its own debian release number by default which is "1" and a 
minus sign just before.

So your library is named "mylib-0.0-1".

The dependency keeps the three version number: "mylib > 0.0.0, mylib << 
0.0.90". Note that Gambas assumes that all release between 0 and 90 are 
compatible - Which is stupid too and I will change that.

But when comparing "0.0-1" with "0.0.0", Debian compares the "." with 
the "-", and decides that "0.0-1" < "0.0.0" (or "0.0-1" > "0.0.90") ! 
Arrgh !

At the moment, you can solve that by checking "Insert release number in 
package version" when generating the MyLib package.

In the future (soon), I will remove this option, and always use the 
entire version for package numbers.

I hope I was clear enough (it's very late).

Regards,
