Hi,

building charm++-6.5.1 with

./build charm++ net-linux-amd64 smp --build-shared --enable-charmdebug --enable-tracing --enable-tracing-commthread

results in this warning:

md/setjmp64.c: In function ‘qt_args_1’:

md/setjmp64.c:55:5: warning: incompatible implicit declaration of built-in function ‘alloca’ [enabled by default]

md/setjmp64.c:56:5: warning: passing argument 1 of ‘longjmp’ from incompatible pointer type [enabled by default]

I don't quite yet understand exactly the flow of the build process, but it appears as though the configure script correctly identifies that my system as alloca.h:

checking "whether has alloca.h "... "yes"

but defines the symbol CMK_HAS_ALLOCA_H, while src/QuickThreads/md/setjmp64.c uses #ifdef ALLOCA_H.

Explicitly added -DALLOCA_H to the compiler argument list removes the warning.

Thanks,

nick
