Linking problem
Hi,
I am Vijay Bhaskar. I am facing some linking problems while
running the program in Diab compiler.
For referrence i am pasting the linking problem below.
Undefined symbol 'atan2' in file 'filename.o'
After that i have added the corresponding library function in
linker options (libm.a) to avoid this problem.
I got rid of above probelm, but i am facing some other problem
which is also pasated below.
Undefined symbol
'__errno_fn' in file 'atan2.o(C:\diab\5.2.1.0\PPCEH\libm.a
I am unable to resolve the above problem.
Can u please provide me the solution to avoid the above problem
(or)
Can u please provide me any new solution, whenver we are using
liabrary functions like atan (or) sqrt.
Kindly do the needful.
Regards,
Vijay Bhaskar

Re: Linking problem
Hello,
Based on your post I assume that you are developing code for the
VxWorks kernel environment. The VxWorks kernel application development
model is rather different from a more standard (say Unix or Windows)
application development model. With VxWorks you do not link (on the
host) your kernel application with the VxWorks libraries. You have to
configure in the system whatever feature you need (here the
INCLUDE_ANSI_MATH component it seems), then link statically or
dynamically (i.e. using the target loader) your kernel application
with the VxWorks image.
Hope this helps,
