After a recent update to my Cygwin installation, suddenly
configure-generated libtool scripts give me this error when compiling
and linking C++ code:
libtool: ignoring unknown tag CXX
And even worse, it tries to use gcc to link, which of course fails
because of undefined symbols provided by libstdc++.
Using the /usr/bin/libtool instead works, so this would seem to be
caused during the generation of the package libtool.
So I guessed that the sed update was the problem, and I was right.
Downgrading sed to 4.1.4-1 makes everything work again.
I'm attaching my cygcheck output (before I downgraded sed).
Thanks for the heads up. I'll try to look in to it, but it might be a
week or two.
I would appreciate any hint here. sed 4.1.5-1 has 0 FAILs in the sed
testsuite and the only really interesting Cygwin related difference
between 4.1.4 and 4.1.5 is that 4.1.4 uses sed's own implementation
of getline(), while 4.1.5 uses the newlib version of getline.
One incompatibility of 4.1.5 is that sed no longer works correctly with
CRLF-style files on binary mounts. For example, 's/^$//' script no
longer filters out empty lines if they are CRLF terminated, but works OK
for LF terminated lines. However, I'm not sure whether this causes the
problem described above.
