perf scripting perl: Force to use stdbool When building perf for arm64 I hit a warning (and be treated as an error) like below: aarch64-oe-linux-gcc -o .../scripts/perl/Perf-Trace-Util/Context.o -c -Wbad-function-cast \ ... scripts/perl/Perf-Trace-Util/Context.c In file included from .../usr/lib64/perl/5.14.3/CORE/perl.h:2464:0, from Context.xs:23: /.../usr/lib64/perl/5.14.3/CORE/handy.h:108:0: error: "bool" redefined [-Werror] # define bool char ^ In file included from /.../usr/src/kernel/tools/include/linux/types.h:4:0, from /.../usr/src/kernel/arch/arm64/include/uapi/asm/sigcontext.h:19, from /.../usr/include/bits/sigcontext.h:27, from /.../usr/include/signal.h:340, from /.../usr/include/sys/param.h:28, from /.../usr/lib64/perl/5.14.3/CORE/perl.h:678, from Context.xs:23: /.../usr/lib/aarch64-oe-linux/gcc/aarch64-oe-linux/4.9.2/include/stdbool.h:33:0: note: this is the location of the previous definition #define bool _Bool Looks like the failure is caused by arm64 uapi/asm/sigcontext.h, which includes linux/types.h while other archs not. Current perl consider this problem: http://perl5.git.perl.org/perl.git/commit/bd31be4baa3ee68abdb92c0db3200efe0fad903b However there are users which use old version of perl. This patch includes stdbool.h before Context.xs and define HAS_BOOL to prevent perl'e headers define its own 'bool'. Code is learn from perl's git tree.
