I'm working with a project that uses auto tools. The project's posture
is a tad bit weak, so I want to add some additional flags and options
to harden it. The folks at the project told me to add my flags and
options to CFLAGS and CXXFLAGS.
It looks like autoconf is failing as shown below. When I look at the
log and then the line number, I see the following:
{ { $as_echo "$as_me:${as_lineno-$LINENO}: error: in \`$ac_pwd':" >&5
$as_echo "$as_me: error: in \`$ac_pwd':" >&2;}
as_fn_error 77 "C compiler cannot create executables
See \`config.log' for more details" "$LINENO" 5; }
It appears a linker flag passed through the compiler driver was
consumed by the assembler.
What is the recommended way to work around this issue?
