            Bug ID: 28177
           Summary: make check has ~150 failures due to `libgcc_s.so.1
                    must be installed for pthread_cancel to work`
           Product: glibc
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: build
          Assignee: unassigned at sourceware dot org
          Reporter: i at maskray dot me
                CC: carlos at redhat dot com
  Target Milestone: ---

(Debian testing amd64, GCC 10.2.1, binutils 2.35.2)

% mkdir -p out/bfd
% ../../configure --prefix=/tmp/glibc/bfd --enable-static-pie
% make -j 20
% make -j 20 check
# many failures due to libgcc_s.so.1 must be installed for pthread_cancel to
work
% ./testrun.sh nptl/tst-cancel1
libgcc_s.so.1 must be installed for pthread_cancel to work
Didn't expect signal from child: got `Aborted'

Copying the system libgcc_s.so.1 to $prefix/lib/ can fix the failures.

% cp /usr/lib/x86_64-linux-gnu/libgcc_s.so.1 /tmp/glibc/bfd/lib/
% ./testrun.sh nptl/tst-cancel1
# succeeded

--- Comment #1 from Fangrui Song <i at maskray dot me> ---
Forgot `cd out/bfd` below `mkdir -p out/bfd`

`make install` before `make check` doesn't work. In ./testrun.sh, 
/usr/lib/x86_64-linux-gnu/libgcc_s.so.1 is not in `search path`
(LD_DEBUG=libs). So a manual copy is needed.

Please talk to Debian or Ubuntu about upstreaming their multiarch patches. The
upstream toolchain is consistent in this area. The issue only happens if you
try to do glibc development on a system that has these custom downstream
patches in its system toolchain.

(Just to be clear, I would like to see these patches upstreamed, it's just not
something I'm sure I can do due to the licensing aspects involved.)
