linux - 如何正确编写 Gentoo 的 ebuild

Question

任何人都可以帮助为 GBS 创建 ebuild ？这是我的作品 ebuild(为 osc 修改的 ebuild):

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*
}

覆盖信息:

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"

当我试图编译这个 ebuild(至少解压)时，我收到以下错误。源码解包输出:

您还没有定义 SRC_URI。这就是它用来下载 tarball 的。您不将其包含在 ebuild 的目录中。即使您事先已经下载了它，您仍然在/usr/portage/distfiles 中。

此外，您的所有功能(除了 pkg_setup，不确定)都是多余的。默认函数可以正常工作，所以请删除它们。
