  26. .SH NAME
  27. curl-config \- Get information about a libcurl installation
  28. .SH SYNOPSIS
  29. .B curl-config [options]
  30. .SH DESCRIPTION
  31. .B curl-config
  32. displays information about the curl and libcurl installation.
  33. .SH OPTIONS
  34. .IP "--ca"
  35. Displays the built-in path to the CA cert bundle this libcurl uses.
  36. .IP "--cc"
  37. Displays the compiler used to build libcurl.
  38. .IP "--cflags"
  39. Set of compiler options (CFLAGS) to use when compiling files that use
  40. libcurl. Currently that is only the include path to the curl include files.
  41. .IP "--checkfor [version]"
  42. Specify the oldest possible libcurl version string you want, and this
  43. script will return 0 if the current installation is new enough or it
  44. returns 1 and outputs a text saying that the current version is not new
  45. enough. (Added in 7.15.4)
  46. .IP "--configure"
  47. Displays the arguments given to configure when building curl.
  48. .IP "--feature"
  49. Lists what particular main features the installed libcurl was built with. At
  50. the time of writing, this list may include SSL, KRB4 or IPv6. Do not assume
  51. any particular order. The keywords will be separated by newlines. There may be
  52. none, one, or several keywords in the list.
  53. .IP "--help"
  54. Displays the available options.
  55. .IP "--libs"
  56. Shows the complete set of libs and other linker options you will need in order
  57. to link your application with libcurl.
  58. .IP "--prefix"
  59. This is the prefix used when libcurl was installed. Libcurl is then installed
  60. in $prefix/lib and its header files are installed in $prefix/include and so
  61. on. The prefix is set with "configure --prefix".
  62. .IP "--protocols"
  63. Lists what particular protocols the installed libcurl was built to support. At
  64. the time of writing, this list may include HTTP, HTTPS, FTP, FTPS, FILE,
  65. TELNET, LDAP, DICT. Do not assume any particular order. The protocols will
  66. be listed using uppercase and are separated by newlines. There may be none,
  67. one, or several protocols in the list. (Added in 7.13.0)
  68. .IP "--ssl-backends"
  69. Lists the SSL backends that were enabled when libcurl was built. It might be
  70. no, one or several names. If more than one name, they will appear
  71. comma-separated. (Added in 7.58.0)
  72. .IP "--static-libs"
  73. Shows the complete set of libs and other linker options you will need in order
  74. to link your application with libcurl statically. (Added in 7.17.1)
  75. .IP "--version"
  76. Outputs version information about the installed libcurl.
  77. .IP "--vernum"
  78. Outputs version information about the installed libcurl, in numerical mode.
  79. This outputs the version number, in hexadecimal, with 8 bits for each part:
  80. major, minor, and patch. So that libcurl 7.7.4 would appear as 070704 and libcurl
  81. 12.13.14 would appear as 0c0d0e... Note that the initial zero might be
  82. omitted. (This option was broken in the 7.15.0 release.)
  83. .SH "EXAMPLES"
  84. What linker options do I need when I link with libcurl?
  85. $ curl-config --libs
  86. What compiler options do I need when I compile using libcurl functions?
  87. $ curl-config --cflags
  88. How do I know if libcurl was built with SSL support?
  89. $ curl-config --feature | grep SSL
  90. What's the installed libcurl version?
  91. $ curl-config --version
  92. How do I build a single file with a one-line command?
  93. $ `curl-config --cc --cflags` -o example example.c `curl-config --libs`
  94. .SH "SEE ALSO"
  95. .BR curl (1)
