[gentoo-user] Can't update to go-1.4.2

[gentoo-user] Can't update to go-1.4.2

[Ajai Khattri]

I know that Go 1.5 is limited to 64bit CPUs but im running on a 64bit CPU 
and Im trying to update Go from 1.0 to the latest stable (which is 1.4.2 
anyway):

dev ~ #  emerge -uDatv dev-lang/go

  * IMPORTANT: 8 news items need reading for repository 'gentoo'.
  * Use eselect news read to view new items.


These are the packages that would be merged, in reverse order:

Calculating dependencies... done!
[ebuild     U  ] dev-lang/go-1.4.2::gentoo [1.0.1::gentoo] 
USE="(-bash-completion%*) (-emacs%) (-pax_kernel%) (-vim-syntax%*) 
(-zsh-completion%)" 0 KiB

Total: 1 package (1 upgrade), Size of downloads: 0 KiB

Would you like to merge these packages? [Yes/No]

Looks like you installed from the wrong tarball...
There's this[1] you can use to change your CHOST but I don't think it'll work 
to go from 32 to 64 bits.
You may need to (at your own risk) build a 64-bit kernel (on another machine 
or with a cross compiler), reboot to it, unpack a 64 tarball except config 
files, update CHOST on make.conf, and rebuild everything. And you will likely 
run into problems along the way.

FYI, this is 32bit Gentoo running on a 64bit virtual machine (so it has a 
64bit kernel) because awhile ago I upgraded from a 32bit setup. Was hoping 
I wouldn't have to reinstall the whole OS...

You have a 64 bit kernel, this is true, but a 32 bit userland.

I don't know how Go does these things but apps don't usually talk to the
kernel directly, they talk to libc. Which in your case is ... 32 bit

Reinstall.

A 32 bit to 64 bit migration may or may not be possible (I never
attempted it) but one thing is sure, it will not be easy.

You may be able to enable the 64bit ABI just for go. I recently did the same 
to enable x32 abi on amd64 for experimenting (which BTW, according to CERN's 
evaluation can save up to 30% memory and 30% cpu usage over amd64 for some 
applications). This is how I did it:

1. From an amd64 stage3 grab the following files and copy them to your system 
(of the libraries you may only need libc.so.6 but I copied them all to be 
safe):

/lib64/libc.so*
/lib64/libm.so*
/lib64/libpthread.so*
/lib64/libdl.so*
/usr/include/gnu/stubs-64.h

2. Add the following to /etc/portage/make.conf:

MULTILIB_ABIS="amd64 x86"

3. Add the following to /etc/portage/profile/use.mask:

-abi_x86_64

4. Rebuild binutils, gcc and glibc (make sure this rebuilds the gcc version 
for the profile that you're using):

# emerge -v sys-devel/binutils sys-devel/gcc sys-libs/glibc

5. Add the following to /etc/portage/env/dev-lang/go and emerge go (if it 
fails to build uncomment the LDFLAGS like, it causes configure failures with 
some packages):

CFLAGS="-m64"
CXXFLAGS="-m64"
#LDFLAGS="-m elf64_x86_64"

This worked for me because the x86_64 gcc can compile x32 code. I believe i686 
can do the same for amd64, it only needs to be rebuilt to get the helper 
libraries (libgcc and friends). Of course, if any other go ebuilds have 
dependencies on other libraries you will have to add the abi_x86_64 use flag 
manually to those libraries (autounmask and the dep solver won't figure it out) 
but you only need to do this for leaf packages that you want to build with an 
alternate ABI. I think you can run "ABI=amd64 emerge ..." to have portage 
solve it but haven't tried it. If you decide to try this let me know if it 
worked.

I don't know if order matters here, but make it "x86 amd64" just in case, Mine 
is "amd64 x86 x32".

Not necessary. It builds successfully with the command:

linux32 emerge go

Without the linux32 pre-command, the go build system detects the system 
as "linux/amd64". However, when adding it the system is identified as 
"linux/386".

(But beware that it will probably cause issues when you update in future)

I've been running a system with 64 bit kernel and 32 bit userspace for 
quite a few years and its only the 4th issue I've hit, so while its 
generally not supported, it still works mostly. For reference, the other 
issues I've hit are:
  - kernel ABI incompatibility with autofs (fixed in a later kernel)
  - virtualbox kernel modules needed to be built 64 bit
  - steam has issues detecting system & tries to launch 64 bit binaries 
(I'll try the linux32 trick with that later too)

I'd never had more than passing interest in go, but tonight I've started 
working through the tutorial & I think I'll keep playing with it for a bit.

Cheers
Bruce
