INLINE function no longer compile

I faced this problem today. I discovered that once you activate compiler optimization, inline functions (like the one in PWM library) compile fine using Eclipse and the tools/tutorial provided by Nordic.

In order to activate compiler optimization, on your makefile, CFLAGS, put or change to any one of these: -O -Og -O1 -O2 -O3

Putting -O0 or nothing does not compile inline functions. Higher number means higher optimization. For example in my case I use -Og because if I use higher it breaks something I still have to fix, but that is another matter.

Have you check for compile in C99 options ? If it's an Eclipse project, default settings is not C99. You'll to set it to compile with inline supports. Try either gcc c99 or iso c99.

Agree with RK that your toolchain is likely not configured correctly in Eclipse so that the inline declarations are not recognized. nAN-29 was not up to date thus removed from the web, but I made a new tutorial here similiar to the appnote. The main difference is that this tutorial uses the GNU ARM Eclipse plug-in which in may experience gives better debug intergration in Eclipse, and also include the built in compiler settings for the GNU ARM compiler.

Still no luck here. I'm gonna go thru the Support Cases to try and resolve this. I've setup this environment a few times before without issue using the nAN-29 as a guide to setup Kepler. At a loss

NAN-29?? That was deprecated and removed ages back and the comment at the time was 'it doesn't work with recent eclipse'.

I suggest either rolling your own, or following Ngugen Hoan Hoang's blog or installing Livio's arm gcc tools using his instructions.

I uninstalled all my tools and eclipse and tried again from scratch but I still get to the same point. In fact now I have a few more - Program "gcc" not found in PATH

I've set this up before and never had these issues. I still can't seem to get the Tool Chain tab to appear in C/C++ Build / Settings. Nor does Cross ARM GCC appear even after installing all the tool chains through eclipse, and follow nAN-29. I'm worried that the Cross ARM GCC in no longer in these tools online! Hope someone can help out with. Very frustrating.

Thanks, I actually came across that stack overflow post today. I've tried re-downloading and re-configuring Eclipse as indicated in that post. Still can't seem to shake these errors.

looks like you don't have the toolchain set up properly as that was the final resolution to that problem which is exactly the same as yours.
