[Qgis-developer] Build compile error

[volkan kepoglu]

I am using Ubuntu in Windows with emulator, VMware workstation 5.5.5
I am new baby in linux, sorry for this.

/usr/local/lib definition exits in /etc/ld.so.conf.d/libc.conf

maybe the problem is related with python, ı do not know, or with emulator.
or maybe it is not a problem. my way is to use qgis bindings in python as
follows;

"/etc/ld.so.conf" inside of file has following;

include /etc/ld.so.conf.d/*.conf
/usr/lib/atlas

in "/etc/ld.so.conf.d" folder there are three files; i486-linux-gun,
libc.conf, libR.conf

libc.conf file has the following;

# libc default configuration
/usr/local/lib
