Automatically compiling dependencies

[440bx]

Hello,

if a program, say "ProgramA" needs "DllB", both written in FPC, is there a way to have Lazarus recompile "DllB" automatically when compiling/building "ProgramA" if it notices that the source of "DllB" has been changed since the last time "DllB" was built ?

Thank you for your help.

But it's just a regular program and not a package, right?

Hello, ASBzone,

Yes/correct.  Just a regular program.

Write a makefile for either fpc or lazbuild as appropriate, or investigate the feasibility of a patch for Lazarus Project Groups.

My rationale for suggesting the latter is based on the assumption that a "quick compile" can be used to determine efficiently how much work needs to be done.

Yes, maybe the LazProjectGroups package should help you (I haven't used it).

An alternative is to use the "Compiler Commands" settings in the Project Options. There you can specify any command line to run before/after compilation (i.e. "hooks"). You can put a lazbuild call there for build your dependent project. The output of this command should also show up in the Messages window.

A last resort is to write a script that builds all dependent projects in the desired sequence. This script can be called directly from the IDE in the menu or with a hotkey if you use External Tools (menu Tools > Configure External Tools).

@n7800,

I'll be giving your suggestions a try soon.  Thank you for pointing them out.
