Help with configure.ac rule wanted

[Uwe Bonnes]

Hello,

for some special hardware, e.g the STLink from ST Microelectronic for
debugging an programming Arm microprocessors, I have translation dlls that
translates the hardware access to libusb calls. To detect libusb, until
recently I added the libusb detection code from
ftp://ftp.etersoft.ru/pub/people/amorozov/usb/
However recenty Alexandre did some work around the configuration area and
things no longer work.

I would appreciate if anybody can help me with coming up with a libusb
detection rule for wine.

Thanks

It would be helpful if you shared your previous patch / what you've
tried that doesn't work.

Rule used so long:
dnl **** Check for LIBUSB ****
AC_SUBST(USBLIBS,"")
AC_SUBST(USBINCL,"")
if test "x$with_usb" != "xno"
then
    AC_CHECK_HEADERS([usb.h],
        AC_CHECK_LIB(usb, usb_init,
            [AC_DEFINE(HAVE_LIBUSB, 1, [Define if you have the libusb library and header])
             USBLIBS="-lusb"]))
    ac_save_CPPFLAGS="$CPPFLAGS"
    if test "$PKG_CONFIG" != "false"
    then
        ac_usb_incl="`$PKG_CONFIG --cflags libusb-1.0`"
        ac_usb_libs="`$PKG_CONFIG --libs libusb-1.0`"
        CPPFLAGS="$ac_usb_incl $CPPFLAGS"
    fi
    AC_CHECK_HEADERS([libusb.h],
        AC_CHECK_LIB(usb-1.0, libusb_init,
            [AC_DEFINE(HAVE_LIBUSB, 1, [Define if you have the libusb library and header])
             USBLIBS="$ac_usb_libs"
             USBINCL="$ac_usb_incl"]))
    CPPFLAGS="$ac_save_CPPFLAGS"
fi
WINE_NOTICE_WITH(usb,[test "x$ac_cv_lib_usb_usb_init" != "xyes" -a "x$ac_cv_lib_usb_1_0_libusb_init" != "xyes"],
                 [libusb ${notice_platform}development files not found, USB won't be supported.])

What I tried last:

dnl **** Check for LIBUSB ****
if test "x$with_usb" != "xno"
then
    WINE_PACKAGE_FLAGS(USB,[libusb-1.0],,,,
        [AC_CHECK_HEADERS([libusb-1.0/usb.h])
        if test "$ac_cv_header_usb_h" = "yes"
        then
            WINE_CHECK_SONAME(usb-1.0, libusb_init,,[USB_CFLAGS=""],[$USB_LIBS])
        else
            USB_CFLAGS=""
        fi])
fi

Hi,
This works fine here:

dnl **** Check for libusb ****
if test "x$with_usb" != "xno"
then
    WINE_PACKAGE_FLAGS(USB,[usb-1.0],,,,
        [AC_CHECK_HEADER([usb.h],
            [WINE_CHECK_SONAME(usb-1.0, libusb_init,,[USB_CFLAGS=""],[$USB_LIBS])],
            [USB_CFLAGS=""])])
fi

(note that you need to run autoconf and autoheader after you did your changes)
