Hi, everyone. I use ROOT v3.01/06 which was compiled on FreeBSD 4.3 using gcc 2.95.3. When I compiled my C++ program by following way, I got message shown bellow. g++ -I$ROOTSYS/include xy_distv22_compile.cpp `root-config --cflags --libs --glibs` $ROOTSYS/lib/libCore.so: warning: tmpnam() possibly used unsafely; consider using mkstemp() What the meaning of the message ? After that, excutable file (a.out) was available. But, I could not show result on display after excuting a.out. Its canvas apeared for a moment and disapeared immediately, while I could get canvas and expected result using not-compiled macro. Why ? Please tell me the reason why these behavior happened. Thank you for your help ! Best regards.
