Hello Andrius,
I owe you an apology. My explanation of the error message was correct, but
I didn't realize that the error was actually emanating from code inside of
blitz. Even thought the error message cites line 7 of testTernary.cpp, the
real problem is within the blitz header file <blitz/array/functorExpr.h>.
We are missing the typename keyword in several places within the definitions
of the BZ_DECLARE_FUNCTOR and BZ_DECLARE_MEMBER_FUNCTION macros. I have
attached a corrected version of this header file, and I will check this into
the blitz cvs repository. Thanks for mentioning this problem.
Regards, Julian C.
