Re: intel sgx psw

Instead of properly moving the .so files I modified the LD_LIBRARY_PATH to use the psw files before the sdk files.

Moving the .so files is how this should be installed, but moving around the loader order essentially gives the same effect without modifying /usr/lib.

I have the above error when I try to use the following PKGBUILD. Why ?

Re: intel sgx psw

I tried running just the linux-sgx-sdk PKGBUILD found in this thread (see below for convenience). I get this error. I get the same error when running `make sgx DEBUG=1` manually from the cloned repo.

From what I can tell, mlfence-after-load is a new as option (see: https://www.phoronix.com/scan.php?page= … tack-perf). I do not have these in my configuration.

  -momit-lock-prefix=[no|yes] (default: no)

  -mfence-as-lock-add=[no|yes] (default: no)
                          encode lfence, mfence and sfence as

Re: intel sgx psw

I managed to successfully complete the install by re-installing binutils using this: https://aur.archlinux.org/packages/gdb-git/ The linux-sgx-sdk PKGBUILD now works for me.

Re: intel sgx psw

@conatus
https://packages.ubuntu.com/bionic-updates/binutils and https://packages.ubuntu.com/bionic/binutils show the version as 2.30-21ubuntu1
2.34.50.20200512 does match https://packages.debian.org/source/expe … l/binutils which is based on an upstream snapshot.
