libcap2 is broken (link). Does not compile anymore.

[vkostas]

libcap2 distribution link http://ftp.sunet.se/pub/Linux/kernel.org/linux/libs/security/linux-privs/libcap2/libcap-2.22.tar.gz is broken. I tried two other sources:

• http://ftp.de.debian.org/debian/pool/main/libc/libcap2/libcap2_2.22.orig.tar.gz
• https://www.kernel.org/pub/linux/libs/security/linux-privs/libcap2/libcap-2.22.tar.gz

without success:

• Error cannot find -lattr (is it because the dependent attr package is not build well???)
• Error Unrecognized option (for some archs)

I tried even the latest version 2.24 without success. Anyone could help?

Please be specific when describing your issue. Changing the download site shouldn't be a problem of course ;) Provide which architectures fail (toolchain+version), and provide the associated build output (one example per) If the issue occurs with legacy toolchains (anything other than 5.2), then fixing it has no/very low prio.

I tried all 5.2 archs. Something related to compiler I think.

Arch-5.2	Result

I only updated PKG_DIST_NAME and PKG_DIST_SITE in Makefile. -PKG_DIST_NAME = $(PKG_NAME)-$(PKG_VERS).$(PKG_EXT) -PKG_DIST_SITE = http://ftp.sunet.se/pub/Linux/kernel.org/linux/libs/security/linux-privs/libcap2 +PKG_DIST_NAME = $(PKGNAME)2$(PKG_VERS).orig.$(PKG_EXT) +PKG_DIST_SITE = http://ftp.de.debian.org/debian/pool/main/libc/$(PKG_NAME)2

Maybe it would look better by changing $(PKG_NAME) to libcap2. PKG_DIST_SITE and -NAME would look a bit better. PKG_DIR would need a change to libcap then, probably. See how it looks ;)

As for the error, the issue is related to the way libcap is compiled. It passes the TC_CFLAGS etc on, as it should, but unrecognized arguments aren't handled by libcap. We can't remove those arguments, because they are needed for compiling other software.

You'll need to test if it works as expected, but try and drop BUILD_CFLAGS from ENV in the spk/Makefile. I have not tested if it actually works, but it should fix the compile errors. That's one way anyway, the other would be to adjust the patch itself to do generally the same thing.

Closing. I hope my info helped a bit, but otherwise, let us know.
