In an attempt to build coreutils with debug symbols, I was surprised to find
that this sequence:
$ git clone https://github.com/coreutils/coreutils
$ cd coreutils/
$ ./bootstrap
$ export CFLAGS=-g
$ ./configure --disable-silent-rules
$ make
resulted in the attached build failure. (The build was clean up to that point.)
Seems to be 100% reproducible: Same behavior seen several times starting
from fresh git clone directory each time. Yet without the CFLAGS=-g, it
builds ok.
What am I doing wrong?
Thanks,
Glenn
