            Bug ID: 28742
           Summary: how to use the x86_64-linux-gnu compiler ?
           Product: glibc
           Version: unspecified
            Status: NEW
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: zimmerma+gcc at loria dot fr
                CC: carlos at redhat dot com
  Target Milestone: ---

thanks to the help of H.J., I was able to build a x86_64-linux-gnu compiler
with build-many-glibcs.py.

Now I want to use that compiler to check the accuracy of the recent libmvec
patches. For this I need to link with MPFR, GMP and libmvec. How to proceed?

So far with the following compilation line:

/localdisk/zimmerma/glibc-many/install/compilers/x86_64-linux-gnu/bin/x86_64-gl\
ibc-linux-gnu-gcc
-I/localdisk/zimmerma/glibc-many/install/host-libraries/inclu\
de -L/localdisk/zimmerma/glibc-many/install/host-libraries/lib -DWITHOUT_OMP
-D\
LIBMVEC -Ofast -DSTR=$f check_exhaustive.c -mavx2 -lm -lmpfr -lgmp -o
/tmp/chec\
k_${f}f

I get:

/tmp/check_acosf: /lib/x86_64-linux-gnu/libmvec.so.1: version `GLIBC_2.35' not
\
found (required by /tmp/check_acosf)
/tmp/check_acosf: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not
fou\
nd (required by /tmp/check_acosf)

When builing glibc there is a testrun.sh wrapper script to use it, is there a
similar wrapper script when using a compiler build from build-many-glibcs.py,
and how to use it?

You need to run /tmp/check_acosf with the testrun.sh wrapper.

Sunil, can create a script which generates a script for
a native compiler built by build-many-glibcs.py to run
binaries with glibc from the native compiler?  The native
compiler is under:

$ ls install/compilers/x86_64-linux-gnu/bin/
x86_64-glibc-linux-gnu-addr2line   x86_64-glibc-linux-gnu-gcov-dump
x86_64-glibc-linux-gnu-ar          x86_64-glibc-linux-gnu-gcov-tool
x86_64-glibc-linux-gnu-as          x86_64-glibc-linux-gnu-gprof
x86_64-glibc-linux-gnu-c++         x86_64-glibc-linux-gnu-ld
x86_64-glibc-linux-gnu-c++filt     x86_64-glibc-linux-gnu-ld.bfd
x86_64-glibc-linux-gnu-cpp         x86_64-glibc-linux-gnu-lto-dump
x86_64-glibc-linux-gnu-elfedit     x86_64-glibc-linux-gnu-nm
x86_64-glibc-linux-gnu-g++         x86_64-glibc-linux-gnu-objcopy
x86_64-glibc-linux-gnu-gcc         x86_64-glibc-linux-gnu-objdump
x86_64-glibc-linux-gnu-gcc-11.2.1  x86_64-glibc-linux-gnu-ranlib
x86_64-glibc-linux-gnu-gcc-ar      x86_64-glibc-linux-gnu-readelf
x86_64-glibc-linux-gnu-gcc-nm      x86_64-glibc-linux-gnu-size
x86_64-glibc-linux-gnu-gcc-ranlib  x86_64-glibc-linux-gnu-strings
x86_64-glibc-linux-gnu-gcov        x86_64-glibc-linux-gnu-strip

Its glibc is under:

$ ls install/compilers/x86_64-linux-gnu/sysroot/
etc  lib  lib64  libx32  sbin  usr  var
$

thank you, Andreas' solution works (taking the testrun.sh script after doing
"make" in the GLIBC master branch). We can thus close the bug.
