[Qemu-devel] [QEMU]How to configure qemu/configure file correctly?

[harryxiyou]

Hi all,

We wanna add a block storage driver named HLFS to QEMU, which
now have to configure qemu/configure file to add following stuffs.

Every developer/user has their own
GLIB_DIR1_INC=/usr/lib/glib-2.0/include
GLIB_DIR2_INC=/usr/include/glib-2.0
HLFS_DIR=/home/jiawei/workshop3/hlfs
LOG4C_DIR=$HLFS_DIR/3part/log
HDFS_DIR=$HLFS_DIR/3part/hadoop
JVM_DIR=/usr/lib/jvm/java-6-openjdk
directory for QEMU compiling so they have to configure qemu/configure file
manually. However, i think it is not convenient(standard) for developer/user to
do them(Manually configure qemu/configure file). I also find other
driver in QEMU
use pkg-config to do this job but i am not clear about this way. Could anyone
give me some suggestions? Thanks in advance.
