        Hello,
I am trying to call function myfun() from TControlBar in standalone program and I have error message
"Function myfun() is not defined in current scope FILE:(tmpfile) LINE:1" if function and dictionary is inside static library. If everything compilled together - all works well.

Could you please help me with it?

Many thanks in advance,
Guennadi.

Working example, everything together.
:::::::::: main.cc :::::::::::
int main()
{

   TApplication theApp("theapp",0,0);
   TControlBar *bar = new TControlBar("vertical", "KEmcDrawPanel",10,10);    bar->AddButton("myfun","myfun()","nothing special");    bar->Show();
   theApp.Run();
return 0;
}
:::::::::: myfun.h :::::::::::
extern void myfun();
:::::::::: myfun.cc :::::::::::
void myfun() { printf("button pressed!\n"); } :::::::::: myfunLinkDef.h :::::::::::
#ifdef __CINT__
#pragma link off all globals;
#pragma link off all classes;
#pragma link off all functions;
#pragma link C++ function myfun;
#endif

:::::::::: link script :::::::::::
rootcint -f myfunDict.cc -c myfun.h myfunLinkDef.h g++ `root-config --cflags` main.cc myfun.cc myfunDict.cc -o example1 `root-config --libs`

NOT working example - "myfun() is not defined in current scope" everything the same except link script
::: link script :::

rootcint -f myfunDict.cc -c myfun.h myfunLinkDef.h
g++ `root-config --cflags` -c main.cc -o main.o
g++ `root-config --cflags` -c myfun.cc -o myfun.o
g++ `root-config --cflags` -c myfunDict.cc -o myfunDict.o

ar lruv libmyfun.a myfun.o myfunDict.o
g++ -o example2 main.o -L./ -lmyfun `root-config --libs`
