What happened to "round" and "pow" functions?
 

About eleven years ago I wrote several small financial programs in C.
Today I went to modify them. When I tried to compile, I got the
messages "Undefined reference to 'pow'" and "Undefined reference to 'round'".

According to the manual, these are defined in math.h. Couldn't find them there
and searches through /usr/include were indefinite at best.

Using gcc-4.4.

TIA, John

Did you remember to link against the math library, i.e. use -lm linker option?

Try using the -lm linker flag when you compile it.

Cheers,

Josh

Thanks. The problem was not using C for too many years.

Operater error, huh? :D
