Re: Use pipe and sed in configure.ac

[Lyre]

Thanks to peter and Eric.

Yes, the problem is the square backect. It should be \([[^ ]]*\).

After I put it in set -vx/set +vx block, I notice the command exactly
executed was:

php-config --configure-options | sed -n 's|.*--with-config-file-scan-dir=\(^
*\).*|\1|p'

both backet were missing.
