tools/perf/Makefile

   1 # The default target of this Makefile is...
   2 all::
   3
   4 # Define V=1 to have a more verbose compile.
   5 #
   6 # Define SNPRINTF_RETURNS_BOGUS if your are on a system which snprintf()
   7 # or vsnprintf() return -1 instead of number of characters which would
   8 # have been written to the final string if enough space had been available.
   9 #
  10 # Define FREAD_READS_DIRECTORIES if your are on a system which succeeds
  11 # when attempting to read from an fopen'ed directory.
  12 #
  13 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
  14 # This also implies MOZILLA_SHA1.
  15 #
  16 # Define CURLDIR=/foo/bar if your curl header and library files are in
  17 # /foo/bar/include and /foo/bar/lib directories.
  18 #
  19 # Define EXPATDIR=/foo/bar if your expat header and library files are in
  20 # /foo/bar/include and /foo/bar/lib directories.
  21 #
  22 # Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
  23 #
  24 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
  25 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
  26 #
  27 # Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
  28 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
  29 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
  30 # some C compilers supported these specifiers prior to C99 as an extension.
  31 #
  32 # Define NO_STRCASESTR if you don't have strcasestr.
  33 #
  34 # Define NO_MEMMEM if you don't have memmem.
  35 #
  36 # Define NO_STRTOUMAX if you don't have strtoumax in the C library.
  37 # If your compiler also does not support long long or does not have
  38 # strtoull, define NO_STRTOULL.
  39 #
  40 # Define NO_SETENV if you don't have setenv in the C library.
  41 #
  42 # Define NO_UNSETENV if you don't have unsetenv in the C library.
  43 #
  44 # Define NO_MKDTEMP if you don't have mkdtemp in the C library.
  45 #
  46 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
  47 #
  48 # Define NO_SYMLINK_HEAD if you never want .perf/HEAD to be a symbolic link.
  49 # Enable it on Windows.  By default, symrefs are still used.
  50 #
  51 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
  52 # tests.  These tests take up a significant amount of the total test time
  53 # but are not needed unless you plan to talk to SVN repos.
  54 #
  55 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
  56 # installed in /sw, but don't want PERF to link against any libraries
  57 # installed there.  If defined you may specify your own (or Fink's)
  58 # include directories and library directories by defining CFLAGS
  59 # and LDFLAGS appropriately.
  60 #
  61 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
  62 # have DarwinPorts installed in /opt/local, but don't want PERF to
  63 # link against any libraries installed there.  If defined you may
  64 # specify your own (or DarwinPort's) include directories and
  65 # library directories by defining CFLAGS and LDFLAGS appropriately.
  66 #
  67 # Define PPC_SHA1 environment variable when running make to make use of
  68 # a bundled SHA1 routine optimized for PowerPC.
  69 #
  70 # Define ARM_SHA1 environment variable when running make to make use of
  71 # a bundled SHA1 routine optimized for ARM.
  72 #
  73 # Define MOZILLA_SHA1 environment variable when running make to make use of
  74 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
  75 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
  76 # choice) has very fast version optimized for i586.
  77 #
  78 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
  79 #
  80 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
  81 #
  82 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
  83 # Patrick Mauritz).
  84 #
  85 # Define NO_MMAP if you want to avoid mmap.
  86 #
  87 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
  88 #
  89 # Define NO_PREAD if you have a problem with pread() system call (e.g.
  90 # cygwin.dll before v1.5.22).
  91 #
  92 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
  93 # generally faster on your platform than accessing the working directory.
  94 #
  95 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
  96 # the executable mode bit, but doesn't really do so.
  97 #
  98 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
  99 #
 100 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
 101 # sockaddr_storage.
 102 #
 103 # Define NO_ICONV if your libc does not properly support iconv.
 104 #
 105 # Define OLD_ICONV if your library has an old iconv(), where the second
 106 # (input buffer pointer) parameter is declared with type (const char **).
 107 #
 108 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
 109 #
 110 # Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
 111 # that tells runtime paths to dynamic libraries;
 112 # "-Wl,-rpath=/path/lib" is used instead.
 113 #
 114 # Define USE_NSEC below if you want perf to care about sub-second file mtimes
 115 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
 116 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
 117 # randomly break unless your underlying filesystem supports those sub-second
 118 # times (my ext3 doesn't).
 119 #
 120 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
 121 # "st_ctim"
 122 #
 123 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
 124 # available.  This automatically turns USE_NSEC off.
 125 #
 126 # Define USE_STDEV below if you want perf to care about the underlying device
 127 # change being considered an inode change from the update-index perspective.
 128 #
 129 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
 130 # field that counts the on-disk footprint in 512-byte blocks.
 131 #
 132 # Define ASCIIDOC8 if you want to format documentation with AsciiDoc 8
 133 #
 134 # Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72.
 135 #
 136 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
 137 # MakeMaker (e.g. using ActiveState under Cygwin).
 138 #
 139 # Define NO_PERL if you do not want Perl scripts or libraries at all.
 140 #
 141 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
 142 # is a simplified version of the merge sort used in glibc. This is
 143 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
 144 #
 145 # Define NO_EXTERNAL_GREP if you don't want "perf grep" to ever call
 146 # your external grep (e.g., if your system lacks grep, if its grep is
 147 # broken, or spawning external process is slower than built-in grep perf has).
