Hi,
About error in imagery/i.class it seems to be generated by lack in MinGW of SIGSTP and SIGALRM signal definitions in mingw/include/signal.h
I added those signals to signal.h as follows
#define SIGTSTP 18 /* Stop Request by Terminal */
#define SIGALRM 13 /* Alarm Signal */
but recompiling it gives an error because of lack of alarm() function in mingw.
Building using CMAKE could be a solution to let it work? I'm googling about that...
Thanks. Regards,
Marco
