[SOLVED] generics with constraints not working

[blochee]

Hello fellow programmers.

I've have another "simplette" (a simple problem).

The following does not work:

Code: [Select]

type
    generic TExample10<T1: class; T2> = class
    end;

begin
end.

The error given:

testing_ground.lpr(2,26) Fatal: Syntax error, ">" expected but ":" found

This example was taken straight from the net at the following site:

http://free-pascal-general.1045716.n5.nabble.com/Feature-announcement-Generic-type-constraints-td5712290.html

Now, that example was posted in Dec, 2012 and I just upgraded to fpc 2.6.4.

Anybody know how to solve the problem?

Most (if not all) of generics features and bug fixes are only available in trunk. 2.6.X will never get generics patches backported, the changes are too radical.

Thanks!  I got the latest trunk and it works.  If anybody else is reading this and is having the same problems, you can find how to install the trunk at:
