Hi thomas,
If you are using use STL "string" as the text string, please obtain the C text string "char *" using c_str. For example:
c->addAreaLayer(DoubleArray(data0, sizeof(data0)/sizeof(data0[0])), 0x806666cc,
POPIS1.c_str());
You may refer to your STL "string" documentation for more details on its c_str method. This method is used to obtain a C text string from an STL text string.
Hope this can help.
Regards
