  1. Prerequisites
  2. =============
  3. When building with support for FTDI FT2232 based devices, you need at least
  4. one of the following libraries:
  5. - libftdi (http://www.intra2net.com/opensource/ftdi/)
  6. - libftd2xx (http://www.ftdichip.com/Drivers/D2XX.htm)
  7. Basic Installation
  8. ==================
  9. OpenOCD is distributed without autotools generated files, i.e. without a
  10. configure script. Run ./bootstrap in the openocd directory to have all
  11. necessary files generated.
  12. You have to explicitly enable desired JTAG interfaces during configure:
  13. ./configure --enable-parport --enable-ftdi2232 --enable-ftd2xx \
  14. --enable-amtjtagaccel
  15. Under Windows/Cygwin, only the ftd2xx driver is supported for FT2232 based
  16. devices. You have to specify the location of the FTDI driver package with the
  17. --with-ftd2xx=/full/path/name option.
  18. Under Linux you can choose to build the parport driver with support for
  19. /dev/parportN instead of the default access with direct port I/O using
  20. --enable-parport_ppdev. This has the advantage of running OpenOCD without root
  21. privileges at the expense of a slight performance decrease.
  22. These are generic installation instructions.
  23. The `configure' shell script attempts to guess correct values for
  24. various system-dependent variables used during compilation. It uses
  25. those values to create a `Makefile' in each directory of the package.
  26. It may also create one or more `.h' files containing system-dependent
  27. definitions. Finally, it creates a shell script `config.status' that
  28. you can run in the future to recreate the current configuration, a file
  29. `config.cache' that saves the results of its tests to speed up
  30. reconfiguring, and a file `config.log' containing compiler output
  31. (useful mainly for debugging `configure').
  32. If you need to do unusual things to compile the package, please try
  33. to figure out how `configure' could check whether to do them, and mail
  34. diffs or instructions to the address given in the `README' so they can
  35. be considered for the next release. If at some point `config.cache'
  36. contains results you don't want to keep, you may remove or edit it.
  37. The file `configure.in' is used to create `configure' by a program
  38. called `autoconf'. You only need `configure.in' if you want to change
  39. it or regenerate `configure' using a newer version of `autoconf'.
  40. The simplest way to compile this package is:
  41. 1. `cd' to the directory containing the package's source code and type
  42. `./configure' to configure the package for your system. If you're
  43. using `csh' on an old version of System V, you might need to type
  44. `sh ./configure' instead to prevent `csh' from trying to execute
  45. `configure' itself.
  46. Running `configure' takes a while. While running, it prints some
  47. messages telling which features it is checking for.
  48. 2. Type `make' to compile the package.
  49. 3. Type `make install' to install the programs and any data files and
  50. documentation.
  51. 4. You can remove the program binaries and object files from the
  52. source code directory by typing `make clean'.
  53. Compilers and Options
  54. =====================
  55. Some systems require unusual options for compilation or linking that
  56. the `configure' script does not know about. You can give `configure'
  57. initial values for variables by setting them in the environment. Using
  58. a Bourne-compatible shell, you can do that on the command line like
  59. this:
  60. CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
  61. Or on systems that have the `env' program, you can do it like this:
  62. env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
  63. Compiling For Multiple Architectures
  64. ====================================
  65. You can compile the package for more than one kind of computer at the
  66. same time, by placing the object files for each architecture in their
  67. own directory. To do this, you must use a version of `make' that
  68. supports the `VPATH' variable, such as GNU `make'. `cd' to the
  69. directory where you want the object files and executables to go and run
  70. the `configure' script. `configure' automatically checks for the
  71. source code in the directory that `configure' is in and in `..'.
  72. If you have to use a `make' that does not supports the `VPATH'
  73. variable, you have to compile the package for one architecture at a time
  74. in the source code directory. After you have installed the package for
  75. one architecture, use `make distclean' before reconfiguring for another
  76. architecture.
  77. Installation Names
  78. ==================
  79. By default, `make install' will install the package's files in
  80. `/usr/local/bin', `/usr/local/man', etc. You can specify an
  81. installation prefix other than `/usr/local' by giving `configure' the
  82. option `--prefix=PATH'.
  83. You can specify separate installation prefixes for
  84. architecture-specific files and architecture-independent files. If you
  85. give `configure' the option `--exec-prefix=PATH', the package will use
  86. PATH as the prefix for installing programs and libraries.
  87. Documentation and other data files will still use the regular prefix.
  88. If the package supports it, you can cause programs to be installed
  89. with an extra prefix or suffix on their names by giving `configure' the
  90. option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
  91. Optional Features
  92. =================
  93. Some packages pay attention to `--enable-FEATURE' options to
  94. `configure', where FEATURE indicates an optional part of the package.
  95. They may also pay attention to `--with-PACKAGE' options, where PACKAGE
  96. is something like `gnu-as' or `x' (for the X Window System). The
  97. `README' should mention any `--enable-' and `--with-' options that the
  98. package recognizes.
  99. For packages that use the X Window System, `configure' can usually
  100. find the X include and library files automatically, but if it doesn't,
  101. you can use the `configure' options `--x-includes=DIR' and
  102. `--x-libraries=DIR' to specify their locations.
  103. Specifying the System Type
  104. ==========================
  105. There may be some features `configure' can not figure out
  106. automatically, but needs to determine by the type of host the package
  107. will run on. Usually `configure' can figure that out, but if it prints
  108. a message saying it can not guess the host type, give it the
  109. `--host=TYPE' option. TYPE can either be a short name for the system
  110. type, such as `sun4', or a canonical name with three fields:
  111. CPU-COMPANY-SYSTEM
  112. See the file `config.sub' for the possible values of each field. If
  113. `config.sub' isn't included in this package, then this package doesn't
  114. need to know the host type.
  115. If you are building compiler tools for cross-compiling, you can also
  116. use the `--target=TYPE' option to select the type of system they will
  117. produce code for and the `--build=TYPE' option to select the type of
  118. system on which you are compiling the package.
  119. Sharing Defaults
  120. ================
  121. If you want to set default values for `configure' scripts to share,
  122. you can create a site shell script called `config.site' that gives
  123. default values for variables like `CC', `cache_file', and `prefix'.
  124. `configure' looks for `PREFIX/share/config.site' if it exists, then
  125. `PREFIX/etc/config.site' if it exists. Or, you can set the
  126. `CONFIG_SITE' environment variable to the location of the site script.
  127. A warning: not all `configure' scripts look for a site script.
  128. Operation Controls
  129. ==================
  130. `configure' recognizes the following options to control how it
  131. operates.
  132. `--cache-file=FILE'
  133. Use and save the results of the tests in FILE instead of
  134. `./config.cache'. Set FILE to `/dev/null' to disable caching, for
  135. debugging `configure'.
  136. `--help'
  137. Print a summary of the options to `configure', and exit.
  138. `--quiet'
  139. `--silent'
  140. `-q'
  141. Do not print messages saying which checks are being made.
  142. `--srcdir=DIR'
  143. Look for the package's source code in directory DIR. Usually
  144. `configure' can determine that directory automatically.
  145. `--version'
  146. Print the version of Autoconf used to generate the `configure'
  147. script, and exit.
  148. `configure' also accepts some other, not widely useful, options.
