Today we see a case like boost. The firsts steps will be:<\/p>\n
eselect boost list<\/code><\/li>\n<\/ol>\nNow, to make sure to don’t break the tree, you will compile all\u00a0stable<\/strong> packages that have boost as DEPEND. To do this task we will use the reverse-dependencies.py<\/a>\u00a0script from the arch-tools<\/a>\u00a0repository ( thanks to\u00a0Pawe\u0142 Hajdan to make it ).<\/p>\nHow reverse-dependencies works? Is very simple, follow this example:<\/p>\n
touch boost_in;touch boost_out<\/code>
\necho \"=dev-libs\/boost-1.49.0-r1\" >> boost_in<\/code>
\necho \"=dev-util\/boost-build-1.49.0\" >> boost_in<\/code>
\npython reverse-dependecies.py -i boost_in -o boost_out<\/code><\/p>\nLet me explain a bit.<\/p>\n
First we have created 2 files;<\/p>\n
\n- in the first will go the package that needs to check.<\/li>\n
- in the last will go the package found by the script.<\/li>\n<\/ul>\n
Yes in this case boost-build is not useful, but this example should tell you that you can put more than one package in the input file(boost_in). With the last command we have now a boost_out structured in this manner:<\/p>\n
# One of the following USE flag combinations is required:
\n# boost
\nsci-mathematics\/singular<\/code><\/p>\nThat obviously means that you need to enable boost USE to make sure that\u00a0sci-mathematics\/singular will use boost.<\/p>\n
<\/p>\n
Now you need to compile all of packages in boost_out list and if you see failure related to boost you need to create a new bug on our bugzilla<\/a>\u00a0and make it as a blocker for boost stabilization.<\/p>\n","protected":false},"excerpt":{"rendered":"This article should be useful for every arch tester that ask how properly test a library.
