[ECOS] private header files unaccessible from package dirs

Hi there,
my package sources are organized into several subdirectories, and I also want to
put private headers into a subdir. However, the compiler is set up to only look
in the source files directory, and the public header directory. What do you
recommend to make the private headers available? I don't wannt to have to prefix
my include files like
#include "pinclude/myheader.h"
and I also don't want to export my privates.

Best,
Heiko

You can add addition compiler flags using

cdl_option CYGPKG_forbar_CFLAGS_ADD 

eg jffs2 has

    cdl_option CYGPKG_FS_JFFS2_CFLAGS_ADD {
        display "Additional compiler flags"
        flavor  data
        no_define
        # We add '-D__ECOS' to trigger eCos-specific code in places.
        # We add '-nostdinc -iwithprefix include' to avoid picking up
        #    native <linux/*.h> include files when building on Linux.
        default_value { "-D__ECOS -nostdinc -iwithprefix include" }
        description   "
            This option modifies the set of compiler flags for
            building the JFFS2 package.
            These flags are used in addition
            to the set of global flags."
        }

So doing something like

        default_value { "-I$(REPOSITORY)/$(PACKAGE)/src/include" }

might work.
