make-3.82 and old glibc

make-3.82 and old glibc

[Oleg Oleshko]

Hello,

in B - Known issues.txt there are a couple of points with make-3.82 and 
old glibc.
I believe we can fix both of them (or fix workarounds at least).

==================================================
First one:
glibc start files and headers fail with: [/usr/include/limits.h] Error 1

Suggested explanation:
Old glibc (and eglibc) Makefiles break with make-3.82. It has the bug 
and patch to fix:
http://savannah.gnu.org/bugs/?30723
In Arch distro make-3.82 goes with this patch, in Slackware 14 without.

Suggested workarounds:

1- rebuild your make-3.82 with above mentioned patch

2- use configparms file in glibc source or build directory, here's the idea:
http://sourceware.org/bugzilla/show_bug.cgi?id=13810#c4

==================================================
Second one:
The build fails with "mixed implicit and normal rules. Stop."

The fix for this issue is already known:
http://www.linuxfromscratch.org/patches/lfs/6.7/glibc-2.12.1-makefile_fix-1.patch

I used the patch from lfs and configparms file and tried to build glibc 
2.7 on
Arch (make-3.82), Slackware (buggy make-3.82) and Ubuntu (make-3.81). 
It's absolutely OK.

Hope, this would be useful.

Best regards,
Oleg

There are already two suggested workarounds for these two issues.

First, crostool-NG can build a make-3.81 for internal use. See that
same file for explanations on how to setup crosstool-NG to do that.

Second, let the user iunstall its own make-3.81, and install it in a
place that is early in the PATH, to ensure it is pcicked up before the
system make.

I would prefer *not* to patch all broken components. For example, even
some versions of the Linux kernel are broken with make-3.82. Patching
all components (known to fail) is not convenient, and we would anyway
need to keep the internal make-3.81 build for cases where the user uses
a local (eg. custom) component that is not patched in this respect.

Yann E. MORIN.
