[opensource-dev] Not actually OT: How do I get/update gcc to 4.6 on debian squeeze?

[Lance Corrimal]

Hi gang,

How do I upgrade gcc to 4.6 on debian squeeze?

And what else does need to be upgraded on debian squeeze to have the versions 
that LL uses?

The wiki page about setting up a build environment on linux still talks about 
gcc 4.3...

Cheers

Hi,


I guess noone else builds on linux AND tries to actually have a build 
environment that is exactly the same as the one Ll uses... Since it is NOT 
DOCUMENTED.

Lance, Oz, plans to release as much as possible about LL linux build system.

While waiting on that I am doing the following for Linux 32 bit on Kokua.
Use a Debian wheezy vm. change the sym links @cpp @g++. @gcc
from gcc-4.7 to gcc-4.6 as it appears to be the same compiler that LL 
backported to squeeze.

Then when run on squeeze the libstdc++ mismatches happened.

To work around that  my hackish approach is to copy the build system libstdc++ 
into
the manifest.

That allows the viewer to run on squeeze without a mismatch.

I don't plan to support anything older than squeeze.

https://bitbucket.org/NickyP/kokua/commits/583f8df7f150aacda096cd3d134f38c4259ce75e


Also, I tested on Linux Mint 17 32 bit and there were no ill effect moving 
forward.

Nicky

Nobody would *want* the exact same build environment that we use.
But Oz is, I believe, running down the info on the tool chain
components.  We're large enough that that info is stuck in a silo
somewhere and we have to blast it out.

Hmm.. maybe change that build environment to something that is actually
compatibel to something that users might have? as in, not using compiler
versions / library versions that aren't available from official
repositories for the distribution in question (prebuilt libs excluded)?

Alternative: package the compiler toolchain as a prebuilt archive, d/l
and unpack into the source tree on build. preferrably as statically
linked stuff.

[Vex Streeter]

Another useful option would be to build and maintain a VM image with the 
complete tool chain installed. It would be great to have as a reference 
and would let people who wanted to cross-compile do it much easier, at 
an obvious cost of VM overhead.  Pity Windows and OSX compilers couldn't 
be VM-ized the same way.

Sorry this has taken so long, but I got it done this morning

I've published the sources for our backport and the debian packages from 
it that we install on our build hosts:


https://wiki.secondlife.com/wiki/Debian_GCC_Backport

and I put a pointer to that page in the Linux compilation instructions.

The wiki page about setting up a build environment on linux still talks about
gcc 4.3...


I would certainly welcome any improvements to that page anyone would 
like to make.  Alas, I don't have the time to do them myself.

gcc v4.6.3 ?... You might want to update to 4.6.4. There have been quite
a few bugs fixed in the latter, see:
https://gcc.gnu.org/bugzilla/buglist.cgi?bug_status=RESOLVED&query_format=advanced&resolution=FIXED&target_milestone=4.6.4

Could it be that there's stuff missing on that page?

I'm getting dependency errors when I try to install those packages...

dpkg: dependency problems prevent configuration of cpp-4.6:

I guess those packages simply do not work... They wont install since they 
require glibc 2.14, and after the failed install your debian is dead:

root@debian-build-6-2:/eregion/public/games/SL/3p/gcc backport for squeeze# 
aptitude search glibc
aptitude: /lib/libc.so.6: version `GLIBC_2.14' not found (required by 
/usr/lib/libstdc++.so.6)
aptitude: /lib/libc.so.6: version `GLIBC_2.14' not found (required by 
/lib/libgcc_s.so.1)


Not amused.

Re: [opensource-dev] Not actually OT: How do I get/update gcc to 4.6 on debian squeeze?

[Nicky Perian]

I have given up on Debian Squeeze. Wheezy delivers gcc-4.6.3 and the sym links 
to gcc g++ cpp etc can be changed to gcc-4.6.
Then for the viewer to run on squeeze I deliver libstc++.so with the viewer 
manifest.
That locks the build to libstc++.so that the viewer was built with. 
I have run the viewer in that configuration on a wide variety of distro's..
