Please patch configure.ac (and ass SYNERGY_AUTORECONF = YES in
synergy.mk) instead of the generated configure script.

Out of interest, on what configs do you see warnings? I haven't noticed
any build errors on the autobuilder.

Hi Peter,

There is no configure.ac in the sources and this is why I patched the
generated configure file.

As for the errors, I guess it depends on the toolchain and gcc version
that is being used. I am seeing something like this:

cc1plus: warnings being treated as errors
CTCPSocket.cpp: In member function 'virtual void CTCPSocket::write(const
void*, UInt32)':
CTCPSocket.cpp:143: warning: 'wasEmpty' may be used uninitialized in
this function

True, but there's configure.in (the old name for configure.ac).

Ok, thanks.

The file is named configure.in. This is the one that should be
modified, and the package marked SYNERGY_AUTORECONF = YES. The
configure shell script is generated by autoconf from configure.in (or
sometimes configure.ac), and therefore should preferably not be
modified directly.

And precisely which toolchain and gcc version are you using? If it
appears that it generates some errors we haven't seen, then we might
include it in our automated build tests, to extend their coverage.

Regards,

Thomas
