Expand description

Represents all reasons pkg-config might not succeed or be run at all.

Variants§

§

EnvNoPkgConfig(String)

Aborted because of *_NO_PKG_CONFIG environment variable.

Contains the name of the responsible environment variable.

§

CrossCompilation

Detected cross compilation without a custom sysroot.

Ignore the error with PKG_CONFIG_ALLOW_CROSS=1, which may let pkg-config select libraries for the host’s architecture instead of the target’s.

§

Command

Failed to run pkg-config.

Contains the command and the cause.

Fields

§command: String
§cause: Error
§

Failure

pkg-config did not exit successfully after probing a library.

Contains the command and output.

Fields

§command: String
§output: Output
§

ProbeFailure

pkg-config did not exit successfully on the first attempt to probe a library.

Contains the command and output.

Fields

§name: String
§command: String
§output: Output
