[Paparazzi-devel] Compiling errors with lost package ivy-glib

[????????]

Hi,all.

    I have found that the compiling errors are caused by the apple's compiler "clang",since apple no longer ships  standard gcc with it's newest Xcode.

    So I installed the gcc4.7 for my paparazzi compiling.Unfortunately,I still get errors later. This time,it seems like that it has missed something while it is compiling.

Here is the errors:

Package ivy-glib was not found in the pkg-config search path.

Perhaps you should add the directory containing `ivy-glib.pc'

to the PKG_CONFIG_PATH environment variable

No package 'ivy-glib' found

OL app_server

app_server.c:42:30: fatal error: libxml/xmlreader.h: No such file or directory

compilation terminated.

make[1]: *** [app_server] Error 1

make: *** [tmtc] Error 2

What's wrong with it?And how could I fix it?thank's very much!!
