When I compiled a simple code like next
TROOT root("rint", "The ROOT Interactive Interface");
int main(int argc, char **argv)
{
TRint *app = new TRint("App",&argc,argv,0,0);
app->Run();
return 0;
}
with MySQLServer.cpp, MySQLResult.cpp, MySQLRow.cpp,
MySQLcint.cpp and linked result with library from MySQL database
all is working excluding TSQLRow operator[]. Last operator must return
result of method GetField(field) but it returns strange large integer
number.
Method GetField works fine itself.
But when I organized DLL library from these codes and tried to load it
by gSYSTEM->Load() the returned code was –1. What is a difference?
Compiler gave the warnings that TSQLServer, TSQLResult and TSQLRow
are not linked as DLL. In principal, now I can use first way and translate
these classes each time when they are necessary. But question remains.

No need to rebuild complete ROOT you only should rebuild the
libMySQL.lib and .dll. If you have pure Win32 version of libmysqlclient
then there is no need of course to run with libcygwin.dll.
Cheers, Fons.
