The mvf_sema4.h file is a part of linux-timesys (3.0.15) kernel (directory include/linux), and should be located in /usr/include/linux in the SDK sysroot. I wanted to create a patch, but did not find an automated solution (as I already described at https://community.freescale.com/message/466383). This issue is not just my case, as you can find for example at the following link: http://developer.toradex.com/how-to/colibri-vf61-real-time-demo-%28xy-pen-plotter%29#Building_the_Qt_User_Interface > > Second (after fixing the first issue manually), linking of such application fails on "-lmcc" flag, as it cannot locate libmcc.so library. In sysroot's /usr/lib, there is only libmcc.so.1.0, but a libmcc.so link is missing. After creating the link manually, the application can build and run as expected. > > I would like to ask for a patch of these two issues, or at least for pointing me to some *brief* resource where I might learn how to create the patch on myself (i.e. what meta-data say yocto how to generate sysroots). Sorry, but studying the whole yocto documentation is just too long run. I spent whole day trying to find a solution with no success. > I'll try a build here to see if I can reproduce the issue you are seeing. Recently this commit b542d3ba472b04fd8759fc34baeda1e7bba31910 addressed some issues with the libmcc install recipes. Copying Max (the commit author) in case this is a familiar issue or perhaps the issue was introduced by that change. For docs, I recommend starting with the yocto developers guide. -- Andy Voltz Timesys Corporation
