Hi all, Well, the subject says almost everything. I was compiling a project of mine in Haiku, and got: error: 'free' was not declared in this scope Since, I guess there actually exists a free call, I wonder if I am missing some include. I have Haiku compiled from sources, with jam @alpha-cd, and installed in a virtual machine with the iso that was generated. gcc reports 4.4.4 version Haiku revision r40887 Best regards and thanks in advance, Rafael Fernández López.
