Hello, gentoo amd64 developers, |
2 |
I found a big problem with gentoo amd64 recently: |
3 |
|
4 |
I'm just switching from x86 to amd64 gentoo, several months ago, everything |
5 |
goes well, but now I have a project that need to compile some 32bit binaries; |
6 |
since my gcc and glibc both have multilib support, originally I don't think it's |
7 |
a problem, just like this hellworld.c program: |
8 |
|
9 |
$ gcc -o hello helloworld.c # will generate a default |
10 |
hello executable, 64bit; |
11 |
$ gcc -m32 -o hello.x86 helloworld.c # specify to generate a 32bit executable |
12 |
|
13 |
So when I want to compile a separate software source, I just setenv |
14 |
CC="gcc -m32" |
15 |
this seems reasonable, but finally it failed with an error, |
16 |
|

|
19 |
Now I know it's because of this software need 32bit libbfd, while the |
20 |
default 64bit |
21 |
libbfd is provided by sys-devel/binutils, so I need a multilib'ed |
22 |
binutils library, |
23 |
but how do I install a 32bit of libbfd in gentoo way? |
24 |
|
25 |
Furthermore, if compiling any other 32bit program on gentoo-amd64, it may need |
26 |
other more 32bit of libraries, |
27 |
|
28 |
Comparing other linux distros like fedora-x86_64 and debian-amd64, I knew there |
29 |
is simple way to archive this goal, just install both binutils.x86_64 |
30 |
and binutils.i686 |
31 |
packages, but on gentoo-amd64, how can we do this in a similarly simple way? |
32 |
|
33 |
How about add USE multilib support of every package that contains libraries? |
34 |
|
35 |
I have asked this problem on #gentoo-amd64 channel, but seemed no people |
36 |
there knew it, so please someone on the mailing list know how to resolve it? |
37 |
|
38 |
Thanks very much, |
