ok, i managed to log in, and my patch indeed solves the reported
problem.
however, there are more issues, coming from parts of the new build
system which i never touched.
so i would like to discuss them, before i remove them:
#1 when building with msys, the new build system includes pd-watchdog
unfortunately, the watchdog uses signals and other quite linux
specific
stuff. i don't know whether this can be ported, and whether this
actually make sense.
conclusion: i would exclude pd-watchdog from all w32 builds (if people
need signals and whatnot, why don't they use an os that has signals
and
whatnot)
I am pretty sure that Cygwin has signals, so pd-watchdog should just
be removed for MinGW/Windows builds.
#2 when building with msys, the compiler is forced to "g++".
there are several problems with this:
-- the user cannot chose the compiler themselves anymore, as the CC
variable is silently ignored and reset to "g++"
-- no check is done whether there actually is an executable named "g+
+",
it is just assumed. this kind of leads autoconf ad absurdum, as we can
simply check for a valid c++ compiler if needed.
-- most important however: compiling Pd with a c++ compiler can be a
bad
idea! the Pd source uses C++ keywords (e.g. "template" is often used).
throwing this code onto a c++ compiler leads to errors.
conclusion: don't force autoconf to use g++ as the c-compiler, but
rather let it choose the right compiler automagically
if we need a c++-aware linker, then we should ask for a c++-aware
linker
(rather than force a c++ compiler). afaik, automake can handle this
with
a 1-liner.
Try building with the ASIO sources, which are C++ and need to be built
with g++. gcc won't link C++ code into a C binary from what I could
tell. So at least the final linking needs to be done with g++. In
makefile.mingw, all C is built with gcc and all C++ is built with g++,
then the whole thing is linked with g++.
