4.7 Specifying the working directory

Each port is extracted in to a working directory, which must be writeable. The ports system assumes that the DISTFILES unpack in to a directory called ${DISTNAME}. In other words, if you have set:

    PORTNAME=      foo
    PORTVERSION=   1.0

then the port's distribution files contain a top-level directory, foo-1.0, and the rest of the files are located under that directory.

There are a number of variables you can set if that is not the case.

4.7.1 `WRKSRC`

The variable lists the name of the directory that is created when the application's distfiles are extracted. If our previous example extracted into a directory called foo (and not foo-1.0) you would write:

    WRKSRC=      foo

or possibly

    WRKSRC=      ${PORTNAME}

4.7.2 `NO_WRKSUBDIR`

If the port does not extract in to a subdirectory at all then you should set NO_WRKSUBDIR to indicate that.

    NO_WRKSUBDIR= yes
