Reference for conanfile.txt sections: requires, generators, etc.
List of requirements, specifying the full reference.
[requires] poco/1.9.4 zlib/1.2.11
This section supports references with version ranges:
[requires] poco/[>1.0,<1.9] zlib/1.2.11
List of tool requirements specifying the full reference.
This section supports references with version ranges.
In practice the
[tool_requires] will be always installed (same as
[requires]) as installing from a conanfile.txt means that
something is going to be built, so the tool requirements are indeed needed.
It is useful and conceptually cleaner to have them in separate sections, so users of this conanfile.txt might quickly identify some dev-tools that they have already installed on their machine, differentiating them from the required libraries to link with.
List of options scoped for each package like package_name:option = Value.
[requires] poco/1.9.4 zlib/1.2.11 [generators] cmake [options] poco:shared=True openssl:shared=True
List of files to be imported to a local directory. Read more: imports.
[requires] poco/1.9.4 zlib/1.2.11 [generators] cmake [options] poco:shared=True openssl:shared=True [imports] bin, *.dll -> ./bin # Copies all dll files from packages bin folder to my local "bin" folder lib, *.dylib* -> ./bin # Copies all dylib files from packages lib folder to my local "bin" folder
The first item is the subfolder of the packages (could be the root “.” one), the second is the pattern to match. Both relate to the local cache. The third (after the arrow) item, is the destination folder, living in user space, not in the local cache.
[imports] section also support the same arguments as the equivalent
imports() method in conanfile.py, separated with an
If your previous folders use an
@ in the path name, use a trailing (even if empty)
@ so the parser correctly gets the folders paths,
lib, * -> /home/jenkins/workspace/conan_test@2/g/install/lib @
- root_package (Optional, Defaulted to all packages in deps): fnmatch pattern of the package name (“OpenCV”, “Boost”) from which files will be copied.
- folder: (Optional, Defaulted to
False). If enabled, it will copy the files from the local cache to a subfolder named as the package containing the files. Useful to avoid conflicting imports of files with the same name (e.g. License).
- ignore_case: (Optional, Defaulted to
False). If enabled will do a case-insensitive pattern matching.
- excludes: (Optional, Defaulted to
None). Allows defining a list of patterns (even a single pattern) to be excluded from the copy, even if they match the main
- keep_path (Optional, Defaulted to
True): Means if you want to keep the relative path when you copy the files from the src folder to the dst one. Useful to ignore (
keep_path=False) path of library.dll files in the package it is imported from.
Example to collect license files from dependencies into a licenses folder, excluding (just an example) .html and .jpeg files:
[imports] ., license* -> ./licenses @ folder=True, ignore_case=True, excludes=*.html *.jpeg
