A simple question: How to use EXPORT_SYMBOL() was created by RushA
hi，
I have a question in using linuxcnc 2.9.
I want to call the function defined in the other module. In module A, I export a function using EXPROT_SYMBOL(). In module B, I use "extern" to declare the function and call it. However, it always tells me "undefined symbol". How to solve this problem?

Presumably this is in C?
You may need ti #include A.h in B.c

hi, thanks!
yes, it's C. I did include A.h in B.c, but it doesn't work.
