构建 ATLAS(以及后来的 Octave 与 ATLAS)

构建 ATLAS(以及后来的 Octave 与 ATLAS)

我正在尝试设置 ATLAS(以便以后可以使用 ATLAS 支持编译 octave)。

如果我没记错的话,由于环境特定的优化,我仍然需要手动构建它。我确实看到了一个用于 ATLAS 的包,但它似乎使用了跨平台通用构建选项(例如“它会很慢”)。

因此,按照文档似乎进展不顺利。作为一名 Java 开发人员,我从来不擅长在这些构建过程中发现错误。我是否缺少依赖项(如果是,是否有任何关于我需要的文档)?

构建针对特定处理器定制的 ATLAS 库的最佳方法是按照以下说明进行操作/usr/share/doc/libatlas3-base/README.Debian(也可以在线阅读这里)。说明中明确告诉了如何重建atlasDebian/Ubuntu 的源包,以便为您提供可以安装在官方存储库中提供的包位置的定制包。

相关摘录如下README.Debian

在您的 ARCH 上构建优化的 Atlas 包

构建您自己的 Atlas 优化包非常简单。只需获取包的源代码及其构建依赖项:

# apt-get source atlas
# apt-get build-dep atlas
# apt-get install devscripts

并从 atlas 源子目录中输入以下内容:

# fakeroot debian/rules custom

它应该生成一个名为的包:

../libatlas3-base_*.deb

它针对 Atlas 所基于的架构进行了优化。然后使用 安装该包dpkg -i

看起来这些就是它所需要的依赖项,构建过程现在正在运行。这些东西永远无法以一种好用的格式轻松记录下来。

对于 Ubuntu(分别为 gfortran、g77 和 f77):

sudo apt-get install gfortran f2c libcnf-dev
