     Could you please check covoar’s wscript has the libdwarf path added?

the path to elftoolchain/libdwarf is not added in covoar


Thanks. I am on FreeBSD and it uses the elftoolchain for it's libdwarf so I did
not see the error as the header matches the one in the rtemstoolkit's libdwarf.

     Also check waf with -v.

  after adding the path it gives the following error with -v

Hmm that is a weird error, the waf script looks to me like it has c++11 support
enabled correctly and the code looks fine to me so I do not understand why this
is happening. I do not see this on FreeBSD with clang.

Would you please try `waf clean build` to see if rebuilding everything fixes 
this?

I will try the patches on Windows, it has gcc as a compiler.


The code built on Windows without error. The MSYS2 g++ is 7.2.0 so I am 
not sure about this.
