[Qemu-devel] [PATCH 6/6] libqblock building system |
Date: |
Mon, 3 Sep 2012 17:18:46 +0800 |
Libqblock was placed in new directory ./libqblock, libtool will build
dynamic library there, source files of block layer remains in ./block.
So block related source code will generate 3 sets of binary, first is old
ones used in qemu, second and third are non PIC and PIC ones in ./libqblock.
Test cases are placed under tests/libqblock/.
