Undefined symbol when __inline is enabled

sreenivasa upadhyaya

Hi, I am using ccs v5.5. I am writing some function like __Inline int add( int a, int b ) { return (_sadd(a,b) ); } This implementation gives undefined symbol error when used. But when __inline is disabled the error disappears. Why is this behaviour so by the compiler. Also i found the __inline specifier works fine for some intrinsics works in lower optimisation levels and fails in high optimization lebels. REGARDS, SREENIVASA U,

You must not use a capital 'I' in the __inline keyword. Is that how it appears in your test case?

Only the optimizer can do function inlining; if the optimizer is off, no functions will be inlined.

The __inline keyword is only a hint; at lower optimization levels might choose not to inline it.

Hi,

The Upper case ' I' was a typo. I use smaller case only.

yes, The optimizer has the option whether to inline the function or not.

But why should the build fail??

It builds for me. But I had to guess at your compiler options and the context in which add is called. Please supply the source code and compiler options you use when you see the build fail. I also need to know the version of the compiler.

Thanks and regards,

Hi Archaeologist , hi George

Thanks a lot for responding.
There was a basic flaw from my side.

Sorry for troubling!
