+Title: True multilib support on amd64 |
| 21 |

+News-Item-Format: 1.0 |

+Display-If-Keyword: ~amd64 |
| 28 |

| 29 |
+Starting on 2015-03-29, we are enabling true multilib support on amd64 |
| 30 |
+and masking the old emul-linux-x86 package sets for removal. This |
| 31 |
+change provides our users with the opportunity to build 32-bit libraries |
| 32 |
+from source with all the flexibility given by ebuilds and the security |
| 33 |
+of using mainline ebuilds, rather than relying on pre-packaged binary |
| 34 |
+versions of them. |
| 35 |
+ |
| 36 |
+The switch to the new system is likely to require a specific action from |
| 37 |
+the users of our multilib profiles. Since the new system collides with |
| 38 |
+the old one, the Package Manager must be able to clearly satisfy all |
| 39 |
+the dependencies using the new system in order to proceed. This may |
| 40 |
+require unmerging packages installed from third-party repositories that |
| 41 |
+have not been updated to support the new system. |
| 42 |
+ |
| 43 |
+In order to enable building necessary 32-bit libraries, users will be |
| 44 |
+required to enable the abi_x86_32 USE flag on respective packages. |
| 45 |
+This can be done using /etc/portage/package.use entries alike |
| 46 |
+the following: |
| 47 |
+ |
| 48 |
+ sys-libs/zlib abi_x86_32 |
| 49 |
+ |
| 50 |
+In most of the cases, Portage will be able to deliver correct |
| 51 |
+suggestions for that when using the --autounmask feature. However, some |
| 52 |
+users may prefer setting ABI_X86 globally to enable 32-bit libraries |
| 53 |
+in all packages that support building them. This can be done using |
| 54 |
+the following package.use entry: |
| 55 |
+ |
| 56 |
+ */* abi_x86_32 |
| 57 |
+ |
| 58 |
+In case of issues, blockers especially, users are recommended |
| 59 |
+to manually uninstall any emul-linux-x86 packages that may have been |
| 60 |
+installed on their systems. This will aid the Package Manager |
| 61 |
+in choosing the correct dependency resolution path. If using Portage, |
| 62 |
+this can be done using the following command: |
| 63 |
+ |
| 64 |
+ $ emerge -C 'app-emulation/emul-linux-x86*' |
| 65 |
+ |
| 66 |
+Note: 32-bit applications may be temporarily broken after this step. |
| 67 |
+Therefore, it should be followed by a @world upgrade immediately. |
