1 # The default target of this Makefile is...
4 # Define V=1 to have a more verbose compile.
5 # Define V=2 to have an even more verbose compile.
7 # Define SNPRINTF_RETURNS_BOGUS if your are on a system which snprintf()
8 # or vsnprintf() return -1 instead of number of characters which would
9 # have been written to the final string if enough space had been available.
11 # Define FREAD_READS_DIRECTORIES if your are on a system which succeeds
12 # when attempting to read from an fopen'ed directory.
14 # Define NO_OPENSSL environment variable if you do not have OpenSSL.
15 # This also implies MOZILLA_SHA1.
17 # Define CURLDIR=/foo/bar if your curl header and library files are in
18 # /foo/bar/include and /foo/bar/lib directories.
20 # Define EXPATDIR=/foo/bar if your expat header and library files are in
21 # /foo/bar/include and /foo/bar/lib directories.
23 # Define NO_D_INO_IN_DIRENT if you don't have d_ino in your struct dirent.
25 # Define NO_D_TYPE_IN_DIRENT if your platform defines DT_UNKNOWN but lacks
26 # d_type in struct dirent (latest Cygwin -- will be fixed soonish).
28 # Define NO_C99_FORMAT if your formatted IO functions (printf/scanf et.al.)
29 # do not support the 'size specifiers' introduced by C99, namely ll, hh,
30 # j, z, t. (representing long long int, char, intmax_t, size_t, ptrdiff_t).
31 # some C compilers supported these specifiers prior to C99 as an extension.
33 # Define NO_STRCASESTR if you don't have strcasestr.
35 # Define NO_MEMMEM if you don't have memmem.
37 # Define NO_STRTOUMAX if you don't have strtoumax in the C library.

47 # Define NO_SYS_SELECT_H if you don't have sys/select.h.
49 # Define NO_SYMLINK_HEAD if you never want .perf/HEAD to be a symbolic link.
50 # Enable it on Windows. By default, symrefs are still used.
52 # Define NO_SVN_TESTS if you want to skip time-consuming SVN interoperability
53 # tests. These tests take up a significant amount of the total test time
54 # but are not needed unless you plan to talk to SVN repos.
56 # Define NO_FINK if you are building on Darwin/Mac OS X, have Fink
57 # installed in /sw, but don't want PERF to link against any libraries
58 # installed there. If defined you may specify your own (or Fink's)
59 # include directories and library directories by defining CFLAGS
60 # and LDFLAGS appropriately.
62 # Define NO_DARWIN_PORTS if you are building on Darwin/Mac OS X,
63 # have DarwinPorts installed in /opt/local, but don't want PERF to
64 # link against any libraries installed there. If defined you may
65 # specify your own (or DarwinPort's) include directories and
66 # library directories by defining CFLAGS and LDFLAGS appropriately.
68 # Define PPC_SHA1 environment variable when running make to make use of
69 # a bundled SHA1 routine optimized for PowerPC.
71 # Define ARM_SHA1 environment variable when running make to make use of
72 # a bundled SHA1 routine optimized for ARM.
74 # Define MOZILLA_SHA1 environment variable when running make to make use of
75 # a bundled SHA1 routine coming from Mozilla. It is GPL'd and should be fast
76 # on non-x86 architectures (e.g. PowerPC), while the OpenSSL version (default
77 # choice) has very fast version optimized for i586.
79 # Define NEEDS_SSL_WITH_CRYPTO if you need -lcrypto with -lssl (Darwin).
81 # Define NEEDS_LIBICONV if linking with libc is not enough (Darwin).
83 # Define NEEDS_SOCKET if linking with libc is not enough (SunOS,
86 # Define NO_MMAP if you want to avoid mmap.
88 # Define NO_PTHREADS if you do not have or do not want to use Pthreads.
90 # Define NO_PREAD if you have a problem with pread() system call (e.g.
91 # cygwin.dll before v1.5.22).
93 # Define NO_FAST_WORKING_DIRECTORY if accessing objects in pack files is
94 # generally faster on your platform than accessing the working directory.
96 # Define NO_TRUSTABLE_FILEMODE if your filesystem may claim to support
97 # the executable mode bit, but doesn't really do so.
99 # Define NO_IPV6 if you lack IPv6 support and getaddrinfo().
101 # Define NO_SOCKADDR_STORAGE if your platform does not have struct
104 # Define NO_ICONV if your libc does not properly support iconv.
106 # Define OLD_ICONV if your library has an old iconv(), where the second
107 # (input buffer pointer) parameter is declared with type (const char **).
109 # Define NO_DEFLATE_BOUND if your zlib does not have deflateBound.
111 # Define NO_R_TO_GCC_LINKER if your gcc does not like "-R/path/lib"
112 # that tells runtime paths to dynamic libraries;
113 # "-Wl,-rpath=/path/lib" is used instead.
115 # Define USE_NSEC below if you want perf to care about sub-second file mtimes
116 # and ctimes. Note that you need recent glibc (at least 2.2.4) for this, and
117 # it will BREAK YOUR LOCAL DIFFS! show-diff and anything using it will likely
118 # randomly break unless your underlying filesystem supports those sub-second
119 # times (my ext3 doesn't).
121 # Define USE_ST_TIMESPEC if your "struct stat" uses "st_ctimespec" instead of
124 # Define NO_NSEC if your "struct stat" does not have "st_ctim.tv_nsec"
125 # available. This automatically turns USE_NSEC off.
127 # Define USE_STDEV below if you want perf to care about the underlying device
128 # change being considered an inode change from the update-index perspective.
130 # Define NO_ST_BLOCKS_IN_STRUCT_STAT if your platform does not have st_blocks
131 # field that counts the on-disk footprint in 512-byte blocks.
133 # Define ASCIIDOC8 if you want to format documentation with AsciiDoc 8
135 # Define DOCBOOK_XSL_172 if you want to format man pages with DocBook XSL v1.72.
137 # Define NO_PERL_MAKEMAKER if you cannot use Makefiles generated by perl's
138 # MakeMaker (e.g. using ActiveState under Cygwin).
140 # Define NO_PERL if you do not want Perl scripts or libraries at all.
142 # Define INTERNAL_QSORT to use Git's implementation of qsort(), which
143 # is a simplified version of the merge sort used in glibc. This is
144 # recommended if Git triggers O(n^2) behavior in your platform's qsort().
146 # Define NO_EXTERNAL_GREP if you don't want "perf grep" to ever call
147 # your external grep (e.g., if your system lacks grep, if its grep is
148 # broken, or spawning external process is slower than built-in grep perf has).
150 # Define LDFLAGS=-static to build a static binary.
152 # Define EXTRA_CFLAGS=-m64 or EXTRA_CFLAGS=-m32 as appropriate for cross-builds.
