Re: [Lazarus] Installing Lazarus 0.9.29 trunk on fpc 2.5.1 trunk: can't make clean all?
So I installed lazarus trunk on FPC 2.4.0 (RC1). Apart from a few issues (debian script does not recognize patch version 0, lazarus and fpc installed in /usr/share instead of /usr/lib), it now works.

[Lazarus] OpenWire for lazarus available at SourceForge
Hi folks, I have added a Lazarus under Windows compatible OpenWire version at SourceForge. https://sourceforge.net/projects/openwireproject/ It requires the 0014881 patch in order to work. Hopefully the patch will be applied to Lazarus sometime soon. This version is tested only under Windows at the moment, and only limited testing has been done, but all the basic functionality appears to work. I will be working on Linux version next. I have it rebuilding there, but there are some threading issues that need to be resolved.
