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!

Looks like the gconv library is expecting to use Newlib and not Redlib.. Try changing your C library to Newlib
