Undefined Symbols with Code Coverage through Gcov

[lpcware]

Hello everyone,

I'm trying to get Code Coverage with this method:
http://mcuoneclipse.com/2014/12/26/code-coverage-for-embedded-target-with-eclipse-gcc-and-gcov/

All the compiler things work fine. I get the .gcno files from the compiler.

Linking the gcov library also works.
But as soon as i call something (__gcov_exit() for example to produce the output) the linker complains about missing symbols:

I intended to use the fopen functionality of Redlib to let the files be written to the local file system on the PC. It looks to me like this should be possible or?

Thanks for any help!

That, indeed, did the trick.

@NXP: It would be great if this would work with Redlib, since it is substanitally smaller than NewLib/NewLib Nano in my case (and I think in most of them)

Now I need to get the rest working, but at least it compiles
