4 pkgconf — a system for configuring build dependency information

7 pkgconf [options] [list of modules]
8
10 pkgconf is a program which helps to configure compiler and linker flags
11 for development libraries. This allows build systems to detect other
12 dependencies and use them with the system toolchain.
13
15 --version
16 Display the supported pkg-config version and exit.
17 --atleast-pkgconfig-version=VERSION
19 Exit with error if we do not support the requested pkg-config
20 version.
21 --errors-to-stdout
23 Print all errors on the main output stream instead of the error
24 output stream.
25 --silence-errors
27 Do not display any errors at all.
28 --list-all
30 Walk all directories listed in the PKG_CONFIG_PATH environmental
31 variable and display information on packages which have regis‐
32 tered information there.
33 --simulate
35 Simulates resolving a dependency graph based on the requested
36 modules on the command line. Dumps a series of trees denoting
37 pkgconf's resolver state.
38 --no-cache
40 Skip caching packages when they are loaded into the internal
41 resolver. This may result in an alternate dependency graph being
42 computed.
43 --ignore-conflicts
45 Ignore ‘Conflicts’ rules in modules.
46 --env-only
48 Learn about pkgconf's configuration strictly from environmental
49 variables.
50 --maximum-traverse-depth=DEPTH
52 Impose a limit on the allowed depth in the dependency graph. For
53 example, a depth of 2 will restrict the resolver from acting on
54 child dependencies of modules added to the resolver's solution.
55 --static
57 Compute a deeper dependency graph and use compiler/linker flags
58 intended for static linking.
59 --shared
61 Compute a simple dependency graph that is only suitable for
62 shared linking.
63 --pure Treats the computed dependency graph as if it were pure. This is
65 mainly intended for use with the --static flag.
66 --no-provides
68 Ignore ‘Provides’ rules in modules when resolving dependencies.
69 --with-path=PATH
71 Adds a new module search path to pkgconf's dependency resolver.
72 Paths added in this way are given preference before other paths.
73 --define-prefix
75 Attempts to determine the prefix variable to use for CFLAGS and
76 LIBS entry relocations. This is mainly useful for platforms
77 where framework SDKs are relocatable, such as Windows.
78 --dont-define-prefix
80 Disables the ‘define-prefix’ feature.
81 --prefix-variable=VARIABLE
83 Sets the ‘prefix’ variable used by the ‘define-prefix’ feature.
84 --relocate=PATH
86 Relocates a path using the pkgconf_path_relocate API. This is
87 mainly used by the testsuite to provide a guaranteed interface to
88 the system's path relocation backend.
89 --dont-relocate-paths
91 Disables the path relocation feature.
92
94 --atleast-version=VERSION
95 Exit with error if a module's version is less than the specified
96 version.
97 --exact-version=VERSION
99 Exit with error if a module's version is not exactly the speci‐
100 fied version.
101 --max-version=VERSION
103 Exit with error if a module's version is greater than the speci‐
104 fied version.
105 --exists
107 Exit with a non-zero result if the dependency resolver was unable
108 to find all of the requested modules.
109 --uninstalled
111 Exit with a non-zero result if the dependency resolver uses an
112 ‘uninstalled’ module as part of it's solution.
113 --no-uninstalled
115 Forbids the dependency resolver from considering 'uninstalled'
116 modules as part of a solution.
117
119 --cflags, --cflags-only-I, --cflags-only-other
120 Display either all CFLAGS, only -I CFLAGS or only CFLAGS that are
121 not -I.
122 --libs, --libs-only-L, --libs-only-l, --libs-only-other
124 Display either all linker flags, only -L linker flags, only -l
125 linker flags or only linker flags that are not -L or -l.
126 --keep-system-cflags, --keep-system-libs
128 Keep CFLAGS or linker flag fragments that would be filtered due
129 to being included by default in the compiler.
130 --define-variable=VARNAME=VALUE
132 Define VARNAME as VALUE. Variables are used in query output, and
133 some modules' results may change based on the presence of a vari‐
134 able definition.
135 --print-variables
137 Print all seen variables for a module to the output channel.
138 --print-provides
140 Print all relevant ‘Provides’ entries for a module to the output
141 channel.
142 --variable=VARNAME
144 Print the value of VARNAME.
145 --print-requires, --print-requires-private
147 Print the modules included in either the Requires field or the
148 Requires.private field.
149 --digraph
151 Dump the dependency resolver's solution as a graphviz ‘dot’ file.
152 This can be used with graphviz to visualize module interdependen‐
153 cies.
154 --path Display the filenames of the ‘.pc’ files used by the dependency
156 resolver for a given dependency set.
157 --env=VARNAME
159 Print the requested values as variable declarations in a similar
160 format as the env(1) command.
161 --fragment-filter=TYPES
163 Filter the fragment lists for the specified types.
164 --modversion
166 Print the version of the queried module.
167
169 PKG_CONFIG_PATH
170 List of secondary directories where ‘.pc’ files are looked up.
171 PKG_CONFIG_LIBDIR
173 List of primary directories where ‘.pc’ files are looked up.
174 PKG_CONFIG_SYSROOT_DIR
176 ‘sysroot’ directory, will be prepended to every path defined in
177 PKG_CONFIG_PATH. Useful for cross compilation.
178 PKG_CONFIG_TOP_BUILD_DIR
180 Provides an alternative setting for the ‘pc_top_builddir’ global
181 variable.
182 PKG_CONFIG_PURE_DEPGRAPH
184 If set, enables the same behaviour as the --pure flag.
185 PKG_CONFIG_SYSTEM_INCLUDE_PATH
187 List of paths that are considered system include paths by the
188 toolchain. This is a pkgconf-specific extension.
189 PKG_CONFIG_SYSTEM_LIBRARY_PATH
191 List of paths that are considered system library paths by the
192 toolchain. This is a pkgconf-specific extension.
193 PKG_CONFIG_DISABLE_UNINSTALLED
195 If set, enables the same behaviour as the --no-uninstalled flag.
196 PKG_CONFIG_LOG
198 ‘logfile’ which is used for dumping audit information concerning
199 installed module versions.
200 PKG_CONFIG_DEBUG_SPEW
202 If set, enables additional debug logging. The format of the
203 debug log messages is implementation-specific.
204 PKG_CONFIG_DONT_RELOCATE_PATHS
206 If set, disables the path relocation feature.
207 PKG_CONFIG_MSVC_SYNTAX
209 If set, uses MSVC syntax for fragments.
210
212 Displaying the CFLAGS of a package:
213 $ pkgconf --cflags foo
214 -fPIC -I/usr/include/foo
