Compile time of resource file
lazarus / 64-FPC development

----------------------------------------------------------------------

Why does compiling this resource unit takes more than 30 seconds?
(Ryzen 9 3900X)
The resource is 8.4 MB.

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i unit

Why you are using old resource file format (Lazarus)? Please use FPC
(native) resource file format.

Because the old stuff is not marked as deprecated? Which it is.

Okay, i could change resource format but the question is: Why is this
so slow? About one year ago i didn't notice any slow compiling of this
unit.

because only the old stuf work as expected with the components icons
in the IDE? but yea other than that you should use an .rc file

Probably due to changes how FPC trunk compiler handles strings and its
conversions to UTF8 and back etc. Also there is a ton new shiny
features added to the trunk compiler.

You might want to test if disabling $LONGSTRINGS feature (aka
reference counted strings) helps.  https://www.freepascal.org/docs-

It will help in so far that his resources will be broken, because the
strings are longer than 255 characters.

But what is the reason for the slowdown. I couldn't remember that
compile times were that bad in the past. Compiling my project in
Lazarus seems to stop for half a minute now.

Hi!

In the Laz resource strings unprintable chars below <= #32 are not
allowed.

So space has to be #32 or '  ' and so on.

The same for chars > #127

Maxbe that is the reason.

Can't be true! The two embedded pdf files work as expeced, so no
issues.
The only problem i have is the very long compile time. This is not a
drama, just curious, because they were unnoticeable some time agao.

Probably the support for Unicode as Cyrax already said
