glibc-2.2.2

[m.brulisauer@systime.ch]

Hi,
I'm compiling glibc-2.2.2 on Linux/Alpha 2.4.2.

linux: 2.4.2
gcc: 2.95.2
make: 3.79.1
libtool: 1.3.5
binutils: 2.10.1.0.7
(all compiled with gcc-2.95.2)

I can't compile the math functions on the alpha platform;
can anybody tell me what I do wrong?

>From the glibc crew I got the answer:


Try a different compiler, perhaps a gcc 3.0 test release.  This is a
compiler bug, there's nothing we can do in glibc.

Is this a bug and is it known to you? Is there a patch for 2.95.2
available?
