This is my sample Perl program, and I'm trying to call a library routine. I
think it should work, but don't know how to debug what it is doing in the
background or where it is failing. It is not providing any error messages that
are useful. I don't see any options to turn on verbose or debugging.
--------------------------------------------
use Inline C => Config => ENABLE => "AUTOWRAP" => LIBS => '-L/usr/local/lib
-lgretl' => INC => '-I/home/Chloe/gretl-1.9.7/lib/src';
libgretl_init();
__END__
__C__
#include "libgretl.h"
#include "gretl_utils.h"
/*void libgretl_init();*/
----------------------------------------------
This is the error message
-------------------------------------------------
$ perl sample.pl
Undefined subroutine &main::libgretl_init called at sample.pl line 4.
-------------------------------------------------------------------
These are the files generated, but I don't see any .c files. Only the config-*,
*.dll, and *.inl have any size.
-----------------------------------------
$ ls -R _Inline/
_Inline/:

This does work, however
