如何正确为Gentoo编写ebuild

Question

有人可以帮忙为GBS创建ebuild吗？ 这是我的工件ebuild （为osc修改的ebuild）：

# Copyright 1999-2013 Gentoo Foundation

EAPI=5

PYTHON_DEPEND="2:2.7:2.7"

inherit distutils

pkg_setup() {
    python_set_active_version 2
    python_pkg_setup
}

src_unpack() {
    unpack ${PF}.tar.gz
}

src_compile() {
    distutils_src_compile
}

src_install() {
    distutils_src_install

    ### Commented from original ebuild #
    #dosym osc-wrapper.py /usr/bin/osc
    #keepdir /usr/lib/osc/source_validators
    #cd "${ED}"/usr/
    #find . -type f -exec sed -i 's|/usr/bin/build|/usr/bin/suse-build|g'   {} +
    #find . -type f -exec sed -i 's|/usr/lib/build|/usr/share/suse-build|g' {} +
    #rm -f "${ED}"/usr/share/doc/${PN}*/TODO*
}

叠加信息：

ls /usr/local/portage/dev-util/gbs/
Manifest  gbs-0.13.tar.gz  gbs-0.13_alpha.ebuild  gbs-0.13_alpha.tar.gz

cat /etc/portage/make.conf | grep DISTDIR
DISTDIR="/usr/local/portage/distfiles"

emerge -s "%@dev-util/gbs"

当我尝试编译此ebuild（至少要解压缩）时，出现以下错误。 解压缩源代码的输出：

您尚未定义SRC_URI。 这就是下载tarball的方式。 您不将其包括在ebuild的目录中。 即使您确实已经事先下载了它，您也可以将它保存在/ usr / portage / distfiles中。

另外，您的所有功能（不确定pkg_setup除外）都是多余的。 默认功能可以正常使用，因此请删除它们。
