Package Information

libfyaml Dependencies

Recommended

libyaml-0.2.5 (for YAML 0.1 support)

[Note]

Note

An Internet connection is needed for some tests of this package. The system certificate store may need to be set up with make-ca-1.16.1 before testing this package.

Installation of libfyaml

Install libfyaml by running the following commands: 

./configure --prefix=/usr --disable-static --without-libclang &&
make

To test the results, issue: make check.

Now, as the root user: 

make install

Command Explanations

--disable-static: This switch prevents installation of static versions of the libraries.

--without-libclang: This option disables the use of the Clang library. As at now the Clang library does not really provide any useful functionality for this package, and enabling it would cause all packages using libfyaml to be unnecessarily linked against the Clang library.
