"Execute before" is executed after resource generation?

Hello,

I'm trying to use the "Compiler commands" -> "Execute before" to generate a file that will be embedded as a resource in the executable, but it seems the command is executed after the resources are compiled (there's a message complaining that the file is not found and in fact when I execute the program the resource is not available). Is there a way around it, other than executing the command manually?

Bye

never mind, now I generate the file inside my program.

If you mean the project .res file:
That is updated on save, which is independent of compile.

Ouch, so my projects that embed files as resources (and I also added those files to the project to be sure they're tracked by lazarus) are working by pure luck.
Or not, since a save happens anyway when the file is modified with the lazarus editor and I use compile or build, right?
What happens if I edit the file with an external editor, it's not currently opened in lazarus (so it won't prompt me to reload it) and I press compile/build/run? Will the .res be regenerated or not? As I said, for the problem at hand I changed the logic, but I'd like to be sure that my project work by design and not by chance.

Bye

In this case, don't use the project.res, but use your own. You can include multiple resource files. So you can generate it before.

I just followed the instructions here (and have been doing it for many years, even if this is the first time I tried to generate the file with "Execute before"):

https://wiki.freepascal.org/IDE_Window:_Project_Options#Resources

though it doesn't say exactly when it is regenerated ("depending on the actions taken in the IDE") it also says "it is therefore a good idea to add the files that are indicated here to the project file as well".

And even if I use a different rc file with {$R myspec.rc}, if the source file with the directive doesn't change it won't be automtically recompiled so no regeneration of the resource file would take place, even if one of the files in myspec.rc has changed, right?

Yes. The IDE/Compiler have no knowledge what you put in the .rc If you don't want the have it rebuild every time you need some logic in your "rc builder" you call in the prebuild step

But if I use the "resources" section in the project options *and* put the file in the project, the IDE could check that the file changed and regenerate the resource file ;-)
(which is what I supposed it did: even if the wiki page doesn't say it explicitly it seems to imply so).
