l4vfs, flips

Hello Christian I am currently trying to port a network server to L4 and I am attempting to use flips in order to enable communication across the network. I am getting the following message after running *make* in the pkg directory. I have tried to check out the l4vfs package but it is not available. Any suggestions will be greatly appreciated.

Hello all I am trying to port a network server to L4 and I have checked out the flips and dde modules using cvs. However when I run make withing my pkg directory I get the message below. I've tried checking out l4vfs in an attempt to solve the problem but with no success. Am I doing something wrong??

Re: ore with fiasco-ux

Thanks, that helped alot on the L4 ore side. Arping seems to run fine now except that packets seem not to be making it to and from the host network . Do I need to configure something for the tunnel for fiasco-ux ??

DROPS and ARM
by Christian Roepke 01 Jun '06

01 Jun '06

Hi, I try to compile DROPS for an ARM processor. So I compiled my own cross compiler arm-unknown-linux-uclibc-gcc (I used Gentoo's cross-toolchain generator crossdev). l4/tool/ compiled correctly, but l4/pkg/ NOT :-( I get this message: === Building IDL & includes of "l4io" === PWD=.../l4/pkg/l4io make -C l4io include make[1]: Entering directory `.../l4/pkg/l4io' Makefile:8: *** Wrong gcc major version "" - use 3.x for l4io. Stop. make[1]: Leaving directory `.../l4/pkg/l4io' make: *** [l4io.headers] Error 2 But I use GCC 3.3.6. See the version output: l4/pkg $ arm-unknown-linux-uclibc-gcc --version arm-unknown-linux-uclibc-gcc (GCC) 3.3.6 (Gentoo 3.3.6, ssp-3.3.6-1.0, pie-8.7.8) Copyright (C) 2003 Free Software Foundation, Inc.
