[PATCH] build: centralize use of extra Cygwin LDFLAGS

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The build was failing with:

  CCLD     lockd.la
libtool:   error: can't build i686-pc-cygwin shared library unless -no-undefined is specified

Rather than add yet another $(CYGWIN_EXTRA_LDFLAGS) to all the
impacted *_la_LDFLAGS, it was easier to just pull the extra
flags into ALL libraries via AM_LDFLAGS.

Then, fix lockd_la_LDFLAGS to include AM_LDFLAGS, like all other
libraries.

Pushing under the build-breaker rule.
