But it seems it may also affect mingw builds on travis. I would resist the temptation to add -Werror in general and to Windows cross-build in particular. Not all warnings can be fixed easily. Often the only option is to hide the warning (e.g, by adding a cast) which imo is not always a good strategy. -Werror just forces one's hand to use tricks that hide warnings.

The plan is to have "default builds (no configure options) on Linux with sufficiently current C compilers" warning-free. Which can be achieved with the current code base. > Not all warnings can be fixed easily.

Older systems will warn, oddball systems will warn, non-default build options will warn (and I take one "unused global variable" warning vs. "adding two lines #ifdef/#endif"). gert
Your patch has been applied to the master branch. commit 1513489be632f6577021e3a0f51799b59c4ace6a Author: Antonio Quartulli Date: Sun Nov 10 14:35:25 2019 +0100 travis: compile with -Werror on Linux Signed-off-by: Antonio Quartulli <a@unstable.cc> Acked-by: Arne Schwabe <arne@rfc2549.org> Message-Id: <20191110133525.6069-3-a@unstable.cc> URL: https://www.mail-archive.com/openvpn-devel@lists.sourceforge.net/msg19094.html Signed-off-by: Gert Doering <gert@greenie.muc.de> -- kind regards, Gert Doering
Forgot to hit send on this, and probably this is only partially relevant now, but here goes.

Unless restricted to a very small cross-section (say gcc x.y + linux) this is going to cause a lot of grief. Note that every check run by configure that succeeds with warnings will become mysterious error at build time. There may be other unexpected failures too. -Werror is never fit for production in my view. There is a reason why warnings are warnings. Just my 2c.

That seems to have been an oversight in how to feed Travis what we want - I saw an update yesterday evening. > Unless restricted to a very small cross-section (say gcc x.y + linux) this > is going to cause a lot of grief.

There is a reason why warnings are warnings. "gcc $current + linux" was the plan, and only do it in Travis, not do it in configure for general consumption. gert

A fix has been sent to the ml yesterday night. That should work as expected. However, note that Travis won't be 100% happy because some compilers don't have the -Wno-stringop-truncation we recently added and configure.ac is failing to detect that.... Cheers,
