The attempt was made with the version of fpcres that comes with the FPC v3.0.4 distribution. Is the ability to compile .rc files in a later version ?
Support for compiling RC files was only
recently added to
fpcres. We've merged that back to 3.2.1 so you can take the
fpcres from FPC 3.2.2 RC1 for this (it's backwards compatible, so you can use it as a drop in replacement, though only the trunk compiler will use it together with the
$R-directive). As remarked in the linked post, you
must call it with the
-of res parameter.
