[foreign-jextract] Using many headers splits generated code in package-private classes

[Filip Krakowski]

Hi,

I am trying to generate bindings for the ucx library 
(https://github.com/openucx/ucx). The input I pass to jextract is the 
following header file (filename = "ucx.h", package = "org.openucx", 
source mode = false).

    /// OpenUCX Transports//
    //#include <uct/api/uct.h>//
    //
    //// OpenUCX Protocols//
    //#include <ucp/api/ucp.h>//
    //
    //// I/O Multiplexing//
    //#include <sys/epoll.h>//
    //#include <sys/eventfd.h>//
    //
    //// File descriptor utilities//
    //#include <fcntl.h>//
    //#include <unistd.h>/

It looks like a large amount of the generated code ends up in numbered 
package-private classes. As an example, I can't access the MethodHandle 
for "eventfd" because it is in a package-private class named 
"org.openucx.ucx_h$1". If I remove the includes for "<uct/api/uct.h>" 
and "<ucp/api/ucp.h>" the generated method is created in class 
"org.openucx.ucx_h" where I can access it./
//
/Is there a way to access code generated in the other (numbered) 
package-private classes I'm missing?

Best regards
Filip
