Hello,

I see that the LCL includes LFM files as resources directly without a *.RC file:

{$R *.lfm}

---

But if I do this with my custom file. E.g.:

{$R *.sql}

I get an "error when compiling resources":

Compile Project, Mode: Debug, Target: Test.exe: Exit code 1, Errors: 1, Warnings: 1
Warning: windres: can't open file `REPLACE': No such file or directory uTest.pas(96,0) Error: Error while compiling resources -> Compile with -vd for more details. Check for duplicates.

---

How is it possible that the LFM files are included directly but *.SQL files are parsed as RC files?

---

I checked the Wiki and Docs, but didn't find any information about it:

https://wiki.freepascal.org/Lazarus_Resources
https://www.freepascal.org/docs-html/prog/progsu67.html#x74-730001.2.67

Thanks
Ondrej

Because the file extension is recognized ? LFM is included as RC_DATA, and probably everything that is not .lfm is assumed to be a RC format.

I believe fpcres also has this check.

Thanks for the tip. I found it - it is directly in the compiler.

In comprsrc.pas TWinLikeResourceFile.IsCompiled there is a logic that defines what the compiler does with the included resource file based on the extension or file header.

I don't like the fact that there are hard-coded constants for what seems to be (for a stranger) arbitrary file extensions and that it is not documented anywhere.

I will raise the question in the FPC mailing list.

Well, developers that are using lazarus and form files know what happens.

This is undoubtedly the majority of FPC users, so I don't think this is an issue.

But it should definitely be documented.

Michael.

It is still confusing - in pas2js any file can be added as a resource with:

{$R abc.xyz}

In FPC only LFM, so hence the question why and how :)
