[Buildroot] Problem building usbutils

[hartleys]

Hello all,

I'm having a couple problems getting usbutils to build with buildroot.

1) usbutils requires libusb
This was the easy one. I just needed to select the libusb package. But,
shouldn't the Config.in for usbutils select it automatically?

2) configure for usbutils outputs error: get libusb 0.1.8 or newer
Not sure how to fix this one. The libusb in buildroot is 0.1.12. It
built fine and the library is in my build_arm/staging_dir/usb/lib
directory. For some reason it's not being found. Can anyone offer so
insite on what I might have setup wrong?

Thanks,
Hartley

edit the version in package/libusb/libusb.mk, and try again.

If it works, send a patch to this list :-)

I'm not sure that will fix the problem. The version in buildroot is
already newer than what libusb is looking for.

I think the problem is the files in build_arm/staging_dir/usr/lib are
not being seen during the configure stage.

I'm out of here for today. I'll try your suggestion tommorrow.

Thanks,
Hartley

Yes, fixed in trunk.

Strange, it builds here (i386).

Could you provide more details, please?

Peter,

Finally got it to work. But I really don't understand why this was
necessary.

In ext-tool.mk I changed the following

-	for FILE in `find $${LIB_DIR} -maxdepth 1 -type l -name
"$${LIB}*"`; do \ 
+	for FILE in `find $${LIB_DIR}/ -maxdepth 1 -type l -name
"$${LIB}*"`; do \ 

I have no idea why adding the extra / fixed the problem but at least it
works.

Hartley

Hello Peter,

I'm building for an arm platform using an extern uclibc-based toolchain.

The libusb package builds fine in build_arm/libusb-0.1.12 and library
file is placed in the build_arm/staging_dir/usr/lib directory. And when
the final root filesystem is created the library file is in
root/usr/lib.

If I then enable the usbutils package and try to run the build it gets
to the configure stage for usbutils and stops at:

Checking for usb_get_string_simple in -lusb... No
Configure: error: get libusb 0.1.8 or newer

I looked at the source for libusb-0.1.12 and the usb_get_string_simple
function does exist in usb.c and is prototyped in usb.h so it should be
available.

The only thing I can figure is the make process is not including my
build_arm/staging_dir/usb/lib in the library search path.

Is there anyway to output this information to verify?

Thanks,
Hartley

Hello Peter,

Strange... If I add LDFLAGS="$(TARGET_LDFLAGS)" I can get usbutils to
build.

In usbutils.mk:

$(USBUTILS_DIR)/.configured: $(USBUTILS_DIR)/.unpacked
	(cd $(USBUTILS_DIR); rm -rf config.cache; \
		$(TARGET_CONFIGURE_OPTS) \
		$(TARGET_CONFIGURE_ARGS) \
+		LDFLAGS= "$(TARGET_LDFLAGS)" \
		ac_cv_func_malloc_0_nonnull=yes \
		./configure \
		--target=$(GNU_TARGET_NAME) \
		--host=$(GNU_TARGET_NAME) \
		--build=$(GNU_HOST_NAME) \
		--prefix=/usr \
	)

I guess this is because the configure script for usbutils uses:

ac_link='$CC -o conftest$ac_exeext $CFLAGS $CPPFLAGS $LDFLAGS
conftest.$ac_ext $LIBS >&5'

To build and link the tests.

Is this the "right" way to fix it?

Thanks,
Hartley
