[opensuse-buildservice] package Provides: not taken into consideration sometimes?
Hi, server:database builds libmysqlclient-devel, which has Provides: mysql-devel = %{version}-%{release} It builds against various SUSE Linux versions, which have the old mysql-devel package. Now php5.spec in server:php has BuildRequires: mysql-devel $ osc meta server:php ... <repository name="server_database_SUSE_Linux_10.0"> <path repository="SUSE_Linux_10.0" project="server:database"/> <arch>i586</arch> <arch>x86_64</arch> </repository> <repository name="server_database_SUSE_Linux_10.1"> <path repository="SUSE_Linux_10.1" project="server:database"/> <arch>i586</arch> <arch>x86_64</arch> </repository> ... The problem is that when building against server_database_SUSE_Linux_10.[01], the resolver picks the old mysql-devel package from the base distribution, which in case of 10.0 causes php5-mysql be linked against the old client library and in case of 10.1 breaks init_buildsystem, because mysql-devel pulls in mysql-client (now from server:database) which pulls in libmysqlclient15 (also from server:database), which installs the same files as mysql-shared. So it seems that if a dependency is satisfied by a package name directly, that package is preferred over packages which satisfy the dependency via Provides:. It works as expected if either all packages satisfy the dependency by package name, or all by Provides:. Eg. mysql-devel pulls in the new mysql-client package (via name), and mysql-client pulls in the new libmysqlclient15 package (via libmysqlclient.so.15(libmysqlclient_15)). So a) is this expected or is it a bug? b) can we work around it somehow? Using BuildRequires: libmysqlclient-devel would be tricky, because php5 builds also against pristine distributions. Thanks.

One solution would be to use 'BuildRequires: libmysqlclient-devel' and do 'Substitute: libmysqlclient-devel mysql-devel' in the distro configs. But still I'd like to know whether the described behavior is correct or not. thanks, Michal --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org

It's expected. It is done to give the user a way to break ambiguities. I.e., if there's an expansion error, you can add the package you want to the BuildRequires and the build will work.

You can add a "Substitute: mysql-devel libmysqlclient-devel" for your repository.

what's the syntax for that? is it used somewhere else that we can use as an example? --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org

The syntax is just: Substitute: <from> [to...] Here are some examples: 1) Delete foo-devel from the BuildRequires Substitute: foo-devel 2) Rename foo-devel to bar-devel Substitute: foo-devel bar-devel 3) Add bar-devel if foo-devel is present Substitute: foo-devel foo-devel bar-devel Cheers, Michael. -- Michael Schroeder mls@suse.de SUSE LINUX Products GmbH, GF Markus Rex, HRB 16746 AG Nuernberg main(_){while(_=~getchar())putchar(~_-1/(~(_|32)/13*2-11)*13);} --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse-buildservice+unsubscribe@opensuse.org For additional commands, e-mail: opensuse-buildservice+help@opensuse.org

I added this line to the server:database repository config and so far it seems to do the right thing. Thanks!
