Subject: [PATCH 39/63] perf tools: Fix cross compile for ARM64
Date: Thu,  7 Nov 2019 15:59:47 -0300	[thread overview]
Message-ID: <20191107190011.23924-40-acme@kernel.org> (raw)
In-Reply-To: <20191107190011.23924-1-acme@kernel.org>

From: John Garry <john.garry@huawei.com>

Currently when cross compiling perf tool for ARM64 on my x86 machine I
get this error:

  arch/arm64/util/sym-handling.c:9:10: fatal error: gelf.h: No such file or directory
   #include <gelf.h>

For the build, libelf is reported off:

  Auto-detecting system features:
  ...
  ...                        libelf: [ OFF ]

Indeed, test-libelf is not built successfully:

  more ./build/feature/test-libelf.make.output
  test-libelf.c:2:10: fatal error: libelf.h: No such file or directory
   #include <libelf.h>
          ^~~~~~~~~~
  compilation terminated.

I have no such problems natively compiling on ARM64, and I did not
previously have this issue for cross compiling. Fix by relocating the
gelf.h include.
