logtalk_compile(File, Flags) logtalk_compile(Files, Flags)
Compiles to disk a source file or a list of source files using a
list of compiler flags. The Logtalk source file name extension (by default,
.lgt) can be omitted. Source file paths can be absolute, relative to
the current directory, or use library notation. This predicate can
also be used to compile Prolog source files as Logtalk source code. When no
recognized Logtalk or Prolog extension is specified, the compiler tries
first to append a Logtalk source file extension and then a Prolog source
file extension. If that fails, the compiler tries to use the file name
as-is. Compiler flags are represented as flag(value). For a description
of the available compiler flags, please see the Compiler flags
section in the User Manual. The recognized Logtalk and Prolog file
extensions are defined in the backend adapter files.
This predicate does not load into memory the compiled source file. If you want to both compile and load a source file, use instead the logtalk_load/2 built-in predicate.
When this predicate is called from the top-level interpreter, relative source file paths are resolved using the current working directory. When the calls are made from a source file, relative source file paths are resolved by default using the source file directory (unless a relative_to flag is passed).
Note that only the errors related to problems in the predicate argument are listed below. This predicate fails on the first error found during compilation of a source file. In this case, no file with the compiled code is written to disk.
The compiler flags specified in the second argument only apply to the files listed in the first argument. Notably, if you are compiling a loader file, the flags only apply to the loader file itself.

Flagslist defines an invalid value for a flag:
