Hi again,
I'm having some issues with boost threads macros. If I compile the
following code :
#include <alchemy/task.h>
#include <boost/thread.hpp>
int main() { return 0; }
g++ b.cc $(xeno-config --alchemy --cflags) $(xeno-config --alchemy
--ldflags) -lboost_system -lboost_thread
It gives me a lot of errors regarding "barrier", a macro present in both
librairies. Copperplate's debug macro also created similar issues with
log4cpp lib.
It compiles only if :
1) Unsetting barrier from alchemy
#include <alchemy/task.h>
#unset barrier
#include <boost/thread.hpp>
int main() { return 0; }
2) Changing the order of the includes (easy here, but hard on a big library)
#include <boost/thread.hpp>
#include <alchemy/task.h>
int main() { return 0; }
I guess it's not a redefinition, but an overloading :
/usr/include/boost/thread/barrier.hpp:138:22: error: too many arguments
provided to function-like macro invocation
explicit barrier(unsigned int count) :
^
/usr/xenomai/include/boilerplate/atomic.h:83:9: note: macro 'barrier'
defined here
#define barrier() __asm__ __volatile__("": : :"memory")
Thanks for your insights !
