After copy the ramfs' "/lib" and "/usr/lib" to outside, build the hello world program again with the dynamic glibc, then put it to ramfs. The hello world program with dynamic glibc can run correctly inside qemu :-) Next, I need focus on networking (I have found qemu related device, and kernel related device, and I also know, it needs telnetd in busy box). But sorry, it seems I can not finish within this month :-( - I wasted much time resources on choosing qemu or sim, next I should notice about it (do not waste time, again). - and another excuse is: I have to do it in my free time (within 2.5 hours per day, in average). My current job is not related with it (at present, it is about Global Platform Java applet for iPhone OS). Next month: - I should finish microblaze qemu test under DejaGNU, should finish within next month (2014-11-30). - I also shall start tile cross compiling for gcc/binutils, and use it to Linux kernel, and test it with qemu. I shall try to finish them within 2 months (finish before 2014-12-31). - At least, finish 1 patch for gcc, 1 patch for binutils, 1 patch for qemu/kvm/xen, 3 patches for kernel, within next month (2014-11-30).
