Building Lazarus
Building or rebuilding Lazarus follows almost exactly the instructions provided with the official sources. The changes made to Lazarus for the Ultibo edition relate mostly to adding and removing menu items and options that are not relevant to embedded development, some of the makefiles have also been modified to remove components and reduce the size of what is distributed.
You will need to add the modified Lazarus sources to your installation before you can build Lazarus, these can be downloaded from the Ultibo Lazarus repository on GitHub. Either download the zip or clone the repository depending on your preference and then overlay the downloaded sources onto your Ultibo core installation.
Once you have the sources installed, open a command prompt and change to the directory where Ultibo core is installed:
cd C:\Ultibo\Core
Set the path to include the Free Pascal compiler version used by Ultibo core:
set path=C:\Ultibo\Core\fpc\3.1.1\bin\i386-Win32
Use make to build Lazarus and all the required components:
make clean all
Make will report any errors, otherwise once the build is completed the newly compiled version of Lazarus will be ready to use.
