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.
