Hi,
While building HYPHY version 0.99 from the sources I ran into the following error:
batchlan.cpp: In function `_String ReturnDialogInput(bool)':
batchlan.cpp:680: error: `fStr' undeclared (first use this function)
batchlan.cpp:680: error: (Each undeclared identifier is reported only once for each function it appears in.)
Error during compilation

Adding the lines:
       char str[16384];
       _String fStr(str);
to the beginning of the function ReturnDialogInput in batchlan.cpp fixes the problem.

Best,
Orna
