 |
|
Hi, folks.
Recently I managed to get 64-bit version of legacy PCB CAD software to run on my computer giving me a chance to make an attempt to get rid of multilib.
I checked my /opt directory and it seems that there are no ELF32 binaries left on my system except libraries.
But I was slightly frighten by various discussions mentioning that it will be not easy to get multilib back if I ever need it.
My decade old Lenovo X230 seems to be to weak for any of this modern Steam or whatever games and, what is worth - I never seem to have time for this. Instead, I may occasionally run 64-bit WinXP VM in Virtual Box.
On the other hand, my system will benefit from 64-bit only set by reducing compilation time on aging hardware.
I wonder if there are any brave enough folks running pure 64-bit desktop and if there are any disadvantages for every-day use scenario in case system is used primitively for Internet surfing, programming and engineering using in-place compiled software.
Thank you. |

Yes, the way back is very hard ... |
I'm not sure if it's even worth it, given that with the binhost one can bring up a new and complete installation in a matter of hours. I say hours because last I did emerge --emptytree it took me like I think 6 hours to reemerge ~1600 packages (during 17.1->23.0 migration).
So I don't think it's that scary.
On the other hand the set of packages built for both 32 and 64 bit can be quite limited, so I don't see much of a benefit, even for older hardware. Especially with the above-mentioned binhost available...
Best Regards,
Georgi
p.s. actually, is going back that hard with the binhost available?

I use no-multilib everywhere except on boxes where I might install some binary distributed games (gog.com). On those same machines I make sure I use glibc as the system libc.

I think having -abi_x86_32 in make.conf will bring the 32bit enabled packages to minimum. For me it's 3 packages.
However I'm not sure how good of a practice that is. Before that it was 9 packages. Without it, portage wants to enable 32 bit abi on those six again. What I was able to find out it the profile enabled 32 bit abi on libomp and it brought it in for clang-runtime, compiler-rt and compiler-rt-sanitizers. The other two are virtual/libcrypt and libxcrypt.
I let it install the binary packages and everything seems to be fine.
However I don't think those will significantly decrease compilation time. Also there's the binhost.
Best Regards,
