This is interesting. The pkgconfig flags do not return a path to the headers and so this has not been present in the builds. It must mean most packages are being built with the gcc and newlib header.<br>
<br>
I am not sure if INCLUDES is always supported. I am wondering if the %{_include} path should be added to the CCFLAGS and CFLAGS?<span class="HOEnZb"><font color="#888888"><br>
