This +change provides our users with the opportunity to build 32-bit libraries +from source with all the flexibility given by ebuilds and the security +of using mainline ebuilds, rather than relying on pre-packaged binary +versions of them. + +The switch to the new system is likely to require a specific action from +the users of our multilib profiles. Since the new system collides with +the old one, the Package Manager must be able to clearly satisfy all +the dependencies using the new system in order to proceed. This may +require unmerging packages installed from third-party repositories that +have not been updated to support the new system. + +In order to enable building necessary 32-bit libraries, users will be +required to enable the abi_x86_32 USE flag on respective packages. +This can be done using /etc/portage/package.use entries alike +the following: + + sys-libs/zlib abi_x86_32 + +In most of the cases, Portage will be able to deliver correct +suggestions for that when using the --autounmask feature. However, some +users may prefer setting ABI_X86 globally to enable 32-bit libraries +in all packages that support building them. This can be done using +the following package.use entry: + + */* abi_x86_32 + +In case of issues, blockers especially, users are recommended +to manually uninstall any emul-linux-x86 packages that may have been +installed on their systems. This will aid the Package Manager +in choosing the correct dependency resolution path. If using Portage, +this can be done using the following command: + + $ emerge -C 'app-emulation/emul-linux-x86*' + +Note: 32-bit applications may be temporarily broken after this step. +Therefore, it should be followed by a @world upgrade immediately. diff --git a/2015/2015-03-28-true-multilib/2015-03-28-true-multilib.en.txt.asc b/2015/2015-03-28-true-multilib/2015-03-28-true-multilib.en.txt.asc new file mode 100644 index 0000000..d0894bb --- /dev/null +++ b/2015/2015-03-28-true-multilib/2015-03-28-true-multilib.en.txt.asc @@ -0,0 +1,19 @@ +-----BEGIN PGP SIGNATURE----- +Version: GnuPG v2 + +iQJ8BAABCgBmBQJVFyVTXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w +ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2REJCMDdDQzRGMERBRDA2RUEwQUZFNDFC +MDdBMUFFQUVGQjQ0NjRFAAoJELB6GurvtEZOzS8P/Rd69CSdiDN2yZhOGWaOwK40 +ueGH7BWTRM0tEovaGNrO2MQaT+ZKXacqoDY0DPLhuC/TMuI+NbvKALeWTEfVZ5d1 +zWckrjzzchc+BoBx6sTV+sSLgFPR9JVZ5HoVJyW+RlKS2Z8bzyKMVg/zd8ViAllG +CqMVcamnLsXZQnJ8wsD+gu+UCvBvQOd0kxWJNQa9FsiYdLnVZQZYdOtfk2DKGvhg +7B1lo1r7O9izZtm0ND//Wu/IJNWEutkD2KmWqdB8SBa5YtMM78IUinzsUExtNAxf +ihZTc/lSYB8fFx88VTso3lo1ndR7MEoMQIyydJJkEeOS1ue4LemuTuLMYHIL1jp4 +J//5EHgFz0zcFR8unUnZBBZDcL+9taTfGiQyNaEu4YQ3K/R56DAkBEHRbIt3dtXS +9/VLbg865JDqxaMsZPff5RwFhUa6WanD3pJDp8GQ+Fg1uG2sSDA/1SsqQjA0vyC7 +pAU6vbK82ZhBGsrwjEhFzGZ3QOLbZfy/l+dULL/zlYTQbwb4xQ8nYbK9EIc41i8e +qIvRsDbQ+Q9boOQB/bm1+2o65+LKs1kPMPcFyANJ1IMEgl1wDwHCqhO30y7MDtbT +eMI6WPG4S4z4/gQNK4WE5/nDB3/sfPuc0zOyMzavFDMeWFHUclDhvTSgi3WN5/vi +vl+tBROxSvJOAVDch6Xs +=hbsM +-----END PGP SIGNATURE-----
