Basile <bluen...@gentoo.org> +Content-Type: text/plain +Posted: 2014-10-04 +Revision: 1 +News-Item-Format: 1.0 +Display-If-Keyword: mips +Display-If-Installed: sys-libs/glibc + +To accomodate the new multilib approach in Gentoo, the mips profiles will be +changing on Oct 11, 2014. The new profile structure will be as follows: + + [1] default/linux/mips/13.0/o32 + [2] default/linux/mips/13.0/n32 + [3] default/linux/mips/13.0/n64 + [4] default/linux/mips/13.0/multilib/o32 + [5] default/linux/mips/13.0/multilib/n32 + [6] default/linux/mips/13.0/multilib/n64 + [7] default/linux/mips/13.0/mipsel/o32 + [8] default/linux/mips/13.0/mipsel/n32 + [9] default/linux/mips/13.0/mipsel/n64 + [10] default/linux/mips/13.0/mipsel/multilib/o32 + [11] default/linux/mips/13.0/mipsel/multilib/n32 + [12] default/linux/mips/13.0/mipsel/multilib/n64 + [13] hardened/linux/musl/mips + [14] hardened/linux/musl/mips/mipsel + [15] default/linux/uclibc/mips + [16] hardened/linux/uclibc/mips + [17] default/linux/uclibc/mips/mipsel + [18] hardened/linux/uclibc/mips/mipsel + +There are a few points to note about the change: + +1) Only the glibc profiles (1-12) are affected. The embedded system profiles +(13-18) will not change. + +2) The glibc profiles will now explicitly state the ABIs. In the case of +non-multilib systems (1-3, 7-9) the stated ABI will be the only ABI available, +while in the case of multilib systems (4-6, 10-12) the stated ABI will be the +default ABI, and the others will be available by setting ABI_MIPS in make.conf. + +3) Profiles 1 and 7 are strictly 32-bit userland, but can run under either a +32-bit or 64-bit kernel. They will have CHOST = mips-unknown-linux-gnu and +mipsel-unknown-linux-gnu, respectively. All the other glibc profiles (2-6, 8-12) +are 64-bits userland and will have CHOST = mips64-unknown-linux-gnu or +mips64el-unknown-linux-gnu. + +4) Only users of profiles 1 and 7 need to change their profiles sym links using +`eselect profile`. However, all users should be aware of the CHOST value on +their system to ensure it remains unchanged after the profile updates. + diff --git a/2014/2014-10-04-restructuring_of_mips_profiles/2014-10-04-restructuring_of_mips_profiles.en.txt.asc b/2014/2014-10-04-restructuring_of_mips_profiles/2014-10-04-restructuring_of_mips_profiles.en.txt.asc new file mode 100644 index 0000000..1de6055 --- /dev/null +++ b/2014/2014-10-04-restructuring_of_mips_profiles/2014-10-04-restructuring_of_mips_profiles.en.txt.asc @@ -0,0 +1,17 @@ +-----BEGIN PGP SIGNATURE----- +Version: GnuPG v2 + +iQIcBAABCAAGBQJUMDhvAAoJEJOE+m71LUu69k8QAIJl00UECVN324GTJJRWoZ2X +F8adQxmSXMo8hwP6pe58cyJRRZGaIDjQu8y84WdRK07DcBXkXYVlTrdxARwIscqJ +8SAsNt3hVgKQNCS2vQaLnjHXtZhzPC+WJL6571SCbmQGyUDxVm9hu13R5UpwHFRI +ZB6HKV2X23lsW6PxNHcKoVu/YQoUzcFstFly0RvUrrNkluuzyoDcn288b7S9Y/eY +0I2ocNdH9B/YkW6LzYU5lO/womX0CorsTBpyIVBfiTSj9whsMgak4kl9fkygjRRY +0ULZ112gxVCcLLaQWgto1qczfo5BYaBVh3Q5jwW/m20aVwotRyynjyzLcVUeZpfP +YB5Sz5fG4bqNLWsKKd1kpJNI8j6NzSmA8jqTSSYlfWrYK2A6Gu7HnIaWPRFc6CkO +hCZA6gFn08HiB/WeGbPfKw+qXn1GX0yMTH1g2VWBY5P3AYd0JjLMim99B7QDBHij +KsChFUPILMEF2igc6bB9CfaN3hGXm8hbrvihxOHJG43aq1nqpdQz57uZBmjBNyi7 +yuCI3EzbvENicH82zE1+XRpYv3gL1+tLC6WRqzHrpDtisdyOj0DLsLjS+44k01at +8TMtHyafp0taBSicTBZJKczeE3tGnvM8OPwSDaWd5u1q4WQle9ERLrf6QJduyG5n +QRs5fsGMjtYxjMbHEUo1 +=eyit +-----END PGP SIGNATURE-----
