Hi, I am trying to build the Debian packages in a chroot, but it always fails during building project udkapi idlc: starting preprocessor failed idlc: compile 'giop.idl' ... dmake: Error code 72, while making '../../../../../unxlngs390.pro/misc/urd_cssgiop.don' Is there anything special? I have setup /proc and installed all needed packages. The same build works in a 'normal' environment. Thanks, Gerhard
