Hi,

which are the main changes when upgrading fpc from 2.6.4 to the current 3.x release?

I remember having tried once for building ppcrossarm. That worked. When compiling my old stuff in lazarus on x64 native it left me with a really big mess. So big I switched back to 2.6.4 without taking any notes...

Since I do not want to do that again I need to know how to prepare properly. I've ssen the release notes in the wiki [1], but there is no comparison between the two lines of development.

TIA,
Marc

Codepage aware strings come to mind...

Changes that may break backwards compatibility are documented at http://wiki.freepascal.org/User_Changes_3.0

Thank you, but I know those documents. The hard part ist to compare backwards version step by version step down to 2.6.4.

Most probably I'll jump right in and fix anything going through he complete pile of sources. Working on a copies or branches certainly, not only switching compilers.
