safety wrapper for IBR-DTN daemon
by Francisco Cuesta 22 Feb '13

22 Feb '13

Good morning, I'm keen on running dtn daemon on another platform and I have found the safety-wrapper.sh on the recipes for OpenWRT. According to the script, after system check it tries to mount the container making use of mountcontainer.sh, my doubt is whether other OS like fedora or ububtu need to have this script too or not. I mean, if I have got the daemon bin, do I have to create a container (for instance on fedora os) as is done on that script before running the daemon bin, or just with proper configuration file and the daemon bin it's enough to start and run the ibrtdtn daemon? Thanks in advance, Regards.

As you can see here http://packages.debian.org/wheezy/libdaemon0 libdaemon should run everywhere. I guess it is not installed correctly in your environment (Not in the library path or something). So if you install libdaemon on the target it should work. There might be an configure option to deactivate libdameon. Something like --without-libdaemon. I am not exactly sure about the exact option atm. Or you can just remove libdaemon devel heders from your build machine. Then configure should detect it and deactivate it.

I was using the ./configure provided by ibrdtn suite to make my target (--build=i686-linux --host=arm-mv5sft-linux-gnueabi --target=arm-mv5sft-linux-gnueabi)but when crosscompiling the ibrdtnd complains that it cannot find the library libdaemon so I thought I had to crosscompile it for my ARM architecure, but I think that the libdaemon doesn't support the arm architecture, because of that I wanted to know how you did the crosscompile it. > > Thanks, > > Fran > > > 2013/2/13 Sebastian Schildt <schildt(a)ibr.cs.tu-bs.de> > Hello, > > Platforms like Raspberry are easy, you can just compile directly on the target. Maybe that is an option in your case? I think our build server uses a qemu environment so we do not need to integrate a physical Pi into our build infrastructure. Both ways are not the fastest, but work pretty well. At least in the case of qemu you can just throw more processing power in..... > AFAIK we do nothing special to compile libdaemon on this platform.

Hello. I just started to use ibr-DTN. I used dtnsend and dtnrecv and they worked. Now I'm trying to use dtninbox/dtnoutbox and it is not working well (probably I'm doing something wrong). First i used the comand: bruno@bruno:~$ dtnoutbox abc /home/bruno/Desktop/gg/ dtn://default-1015PEM files: Untitled2 On the other PC I used: dtninbox abc /home/default/Desktop/ And nothing happens In the deamon i noticed the following messages on the receiving node: Wed Feb 20 11:07:28 2013 NOTICE: BundleReceivedEvent: Bundle received [414673649.245] dtn://bruno/abc -> dtn://default-1015PEM from dtn://bruno Wed Feb 20 11:07:28 2013 NOTICE: QueueBundleEvent: New bundle queued [414673649.245] dtn://bruno/abc Wed Feb 20 11:07:28 2013 NOTICE: BundleEvent: bundle [414673649.245] dtn://bruno/abc received Wed Feb 20 11:07:28 2013 NOTICE: BundleEvent: bundle [414673649.245] dtn://bruno/abc deleted Wed Feb 20 11:07:28 2013 NOTICE: BundlePurgeEvent: purging bundle [414673649.245] dtn://bruno/abc Can somebody help me?

Good morning, I still trying to cross-compile the project to an ARM architecture, I have noticed that you could create the projects packets for RasperriPi, which I assume contains an ARM processor. May you tell me how you did the crosscompilation for this platform?? I'm specially interested on how you did the crosscompilation of libdaemon library for arm since I'm getting trouble in achieve the same goal.

Hello, I'm trying to cross-compile the project for an arm-mv5sft-linux-gnueabi processor,I have set the ./configure in this way on the terminal ./configure --build=i686-linux --host=arm-mv5sft-linux-gnueabi --target=arm-mv5sft-linux-gnueabi CC=~/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-gcc CXX=~/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-g++ LD=~/s/arm-mv5sft-linux-gnueabi/SW3.2p1/arm-mv5sft-linux-gnueabi/bin/arm-mv5sft-linux-gnueabi-ld LDFLAGS=-L/usr/include/libdaemon --with-sysroot=/home/thales/s/arm-mv5sft-linux-gnueabi/SW3.2p1/arm-mv5sft-linux-gnueabi --prefix=/justInstalled --disable-shared --enable-threads=posix --enable-long-long --enable-target-optspace --disable-nls --with-float=soft --disable-multilib --enable-symvers=gn The configuration succeeded, however when I do make I got an inclusion error libtool: link: warning: library `/home/j/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/../lib/gcc/arm-mv5sft-linux-gnueabi/4.3.2/../../../../arm-mv5sft-linux-gnueabi/lib/libstdc++.la' was moved.

Good moring, Sorry for repeating myself on the previous mail... I was testing some other crosscompilations with other archicture, a arm-linux-gnueabi, using linux (ubuntu) terminal in order to check whether the parameters which I impose are correct or not. Thus, I have made use of ./configure like this *./configure --build=i686-linux --host=arm-mv5sft-linux-gnueabi --target=arm-mv5sft-linux-gnueabi CC=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-gcc CXX=/home/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/bin/arm-mv5sft-linux-gnueabi-g++ --with-gnu-ld --with-sysroot=/h/t/s/arm-mv5sft-linux-gnueabi/SW3.2p1/arm-mv5sft-linux-gnueabi CFLAGS="-m32" LDFLAGS="-m32" --prefix=/ibrdtn-svn/dtnCross/* However, after chenking the configure output (I've attached a snippet below) I have realized that the compilers aren't set properly, should I include the path where the compiler are in instead of setting the flags? ... checking for arm-mv5sft-linux-gnueabi-g++... no checking for arm-mv5sft-linux-gnueabi-c++... no checking for arm-mv5sft-linux-gnueabi-gpp... no checking for arm-mv5sft-linux-gnueabi-aCC... no checking for arm-mv5sft-linux-gnueabi-CC... no checking for arm-mv5sft-linux-gnueabi-cxx... no checking for arm-mv5sft-linux-gnueabi-cc++... no checking for arm-mv5sft-linux-gnueabi-cl.exe... no checking for arm-mv5sft-linux-gnueabi-FCC... no checking for arm-mv5sft-linux-gnueabi-KCC... no checking for arm-mv5sft-linux-gnueabi-RCC... no checking for arm-mv5sft-linux-gnueabi-xlC_r... no checking for arm-mv5sft-linux-gnueabi-xlC... no ...

Hello, I have a question concerning to how did you cross-compile ibtrdt suite for openwrt in a terminal first you configure ibrdtn project with ./configure indicating that the target was a mips processor and you passed as compiler the one in hte toolchain of OpenWRT, am I mistaken?
