tools/perf: Fix static build of perf tool

2011-06-16T08:17:39Z

To build a statically linked version of the perf tool all needed libraries must be added in the correct order to get the symbols resolved. Currently this is broken when, e.g. python or newt support is enabled -- libpython needs libpthread which is an unconditional link dependency of the perf tool; libslang needs libm, another unconditional dependency. To solve the problem in the long run without the need to keep track of transitive library dependencies, simply make the linker look at the EXTLIBS multiple times until it has all symbols resolved.

perf tools: Makefile: Use gcc to determine ARCH

2011-05-07T09:40:59Z

The original Makefile uses "uname -m" to determine ARCH. This causes problem on x86 when compile perf tool on 32 bit userspace with a 64 bit kernel. bench/../../../arch/x86/lib/memcpy_64.S: Assembler messages: bench/../../../arch/x86/lib/memcpy_64.S:28: Error: bad register name `%rdi' This is because "uname -m" returns x86_64 and memcpy_64.S is included in 32 bit build.

perf tools: Makefile: PYTHON{,_CONFIG} to bandage Python 3 incompatibility

2011-04-19T11:18:36Z

Currently, Python 3 is not supported by perf's code; this can cause the build to fail for systems that have Python 3 installed as the default python: python{,-config} The Correct Solution is to write compatibility code so that Python 3 works out-of-the-box. However, users often have an ancillary Python 2 installed: python2{,-config} Therefore, a quick fix is to allow the user to specify those ancillary paths as the python binaries that Makefile should use, thereby avoiding Python 3 altogether; as an added benefit, the Python binaries may be installed in non-standard locations without the need for updating any PATH variable. This commit adds the ability to set PYTHON and/or PYTHON_CONFIG either as environment variables or as make variables on the command line; the paths may be relative, and usually only PYTHON is necessary in order for PYTHON_CONFIG to be defined implicitly. Some rudimentary error checking is performed when the user explicitly specifies a value for any of these variables. In addition, this commit introduces significantly robust makefile infrastructure for working with paths and communicating with the shell; it's currently only used for handling Python, but I hope it will prove useful in refactoring the makefiles. Thanks to: Raghavendra D Prabhu for motivating this patch.

perf tools: Makefile: Clean up `python/perf.so' rule

2011-04-19T11:18:36Z

There is no need for a subshell or an explicit `export'; as per the POSIX Shell Command Language specification: http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_09_01 http://pubs.opengroup.org/onlinepubs/009695399/utilities/xcu_chap02.html#tag_02_10_02 It is only necessary to include the environment variable assignment just before the command to be run. Also, it is better to use single-quotes, because GNU make might expand `$(BASIC_CFLAGS)' into something that the shell could interpret within double-quotes.

perf tools: Fix NO_NEWT=1 python build error

Fix the following build error: GEN python/perf.so In file included from util/evsel.h:10, from util/python.c:6: util/hist.h:106:18: error: newt.h: No such file or directory error: command 'x86_64-pc-linux-gnu-gcc' failed with exit status 1 make: *** [python/perf.so] Error 1 by passing BASIC_CFLAGS to setup.py. BASIC_CFLAGS variable contains the -DNO_NEWT_SUPPORT switch which prevents building python c extension with newt.

perf tools: Makefile: Remove various and sundry cruft

2011-02-18T09:43:06Z

This commit squashes several commits that remove: unnecessary uname calls `sh -c' BUILT_INS and QUIET_BUILT_IN They have no effect, and the `fixup-builtins' and `check-builtins.sh' scripts don't even exist. RUNTIME_PREFIX It's currently never anything but unset, and it's apparently only meaningful when Microsoft Windows is the operating system (according to the source for git). TEST_PROGRAMS EXTRA_PROGRAMS unused SHELL_PATH_SQ portions unused test for V=2 useless exports Only when `V' is undefined (that is, only when the value of `V' is empty) is `export V' performed, which just has the effect of placing the empty-valued variable `V' in the environment. The only other script to make use of `V' is `Documentation/Makefile', which only checks whether `V' is undefined (that is, whether the value of `V' is empty); hence, the `export V' has no effect whatsoever. Similarly, `export QUIET_GEN' is useless because it will only have a non-empty value when `V' has an empty-value, and when `V' has an empty-value, `QUIET_GEN' is always explicitly set in every script in which it is used. `DESTDIR' is only ever defined by the user via the environment or the command line, both of which are automatically exported to sub-make processes. Furthermore, no non-make sub-scripts make use of `DESTDIR' as an environment variable. No other scripts use `perfexec_instdir'. unused QUIET_SUBDIR{0,1} TAR and RPMBUILD PTHREAD_LIBS Maintainer's dist rules and commands distclean target Test suite coverage testing PRINT_DIR and NO_SUBDIR `configure' target NO_CURL @@PERF_VERSION@@ substitution Without the sed command, all of the rule's commands can be reduced to a single line that copies a file and sets the permissions properly in the process. `make test' echo line template_instdir PERF-BUILD-OPTIONS double-colon rules The use of double-colon rules seems misguided or vestigial git.
