Question to @svalo: how did you apply your patch? I tried to do it several times but every time it gives me rejects. Can you post your patch elsewhere?

Source repository has moved, the new home is https://github.com/oracle/bpftune the following patch includes also the other suggested changes

The current build issue seems to be caused by the fact that the PKGBUILD file uses a sed command to replace occurrences of /lib64 with /lib, but the current source code uses the string "lib64" without the leading slash. The current README includes an officially supported way to make this change instead (source):

$ make libdir=lib
$ sudo make install libdir=lib

The current PKGBUILD also does something similar to change sbin to bin; it doesn't look like there's an officially supported way to do that at the moment, but that could present a similar issue in the future.

Fails to install with:

error: failed to commit transaction (conflicting files)
bpftune-git: /usr/lib64 exists in filesystem (owned by filesystem)

This repository has been moved from https://github.com/oracle-samples to https://github.com/oracle.

The dynamic linker searches in /usr/lib by default. No need for installing libbpftune.conf to /etc/ld.so.conf.d:

[ -d "${pkgdir}/etc" ] && rm -r "$pkgdir"/etc

Secondly, the package() function currently puts two exact copies into /usr/lib. Only the versioned libbpftune .so should go in there. The other one needs to be a symlink to it:

# make libbpftune.so a symlink to libbpftune.so.0.1.3

[ -f "${pkgdir}/usr/lib/libbpftune.so" ] && rm "${pkgdir}/usr/lib/libbpftune.so"

ln -fs /usr/lib/libbpftune.so.0.1.3 "$pkgdir"/usr/lib/libbpftune.so

HTH

Thanks for offering this package in the AUR. Some remarks:

• clang already pulls in llvm-libs, that can be removed from makedepends;
• make -j1 is needed to build succesfully;
• reported generated warnings about potential memory leaks upstream.

This one is (currently) working. :)

This don't work for me.
