Hello IBR staff,
I was wondering whether you have available a version of ibr dtn openwrt packages for broadcom 2708 chipset, it is based on arm architecture, quite similar to raspberri pi.
I have seen here http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/download#OpenWRTrepo... that you mention the possibility to find different architectures in your jetkins builder, however, I could find any reference to broadcom architecture there.
Therefore, I tried to crosscompilie ibr dtn from source aiming to that architecture and with openwrt as OS. I got the daemon, libraries and binaries, but now I get the following error when trying to start the daemon itself.
root@OpenWrt:~# dtnd dtnd: error while loading shared libraries: libm.so.0: cannot open shared object file: No such file or directory
Did I miss to include some library when crosscompiling? Or I am missing it on my openwrt OS? In such a case, what libraries should I install?
Thanks in advance,
Regards!

Hello Juliano,
Thanks for replying, the point is that I don't know what library I have to install in order to get libm.so.0 on openwrt. I mean, I think maybe my OpenWRT OS is lacking that library and I don't know which package I should install to get it.
Thanks again,
Regards

Hello,
You did not specify exactly how you cross-compiled, but I guess your build is broken. Unfortunately there is much more to cross-compiling than just choosig the right architecture.
libm.so normally contains basic math functions, which defintely are available on your plattform „somehow“, however maybe they are in your uclibc (or glibc which are you using?) and not seperately or you might need to statically link them. At least it sounds like maybe you accidentally linked with a host library instead of the target, or your cross-compiling environment did not match the target.
There are buildroot (which is used by OpenWRT) recipes for all IBR-DTN components, which you can find here
https://github.com/ibrdtn/ibrdtn/tree/master/recipes/buildroot
If your build has not been created with buildroot you should try to make this work first. If it is, maybe describe what you needed to change to make it compile.
Just using „any“ toolchain that targets the processor (e.g. using a toolchain for A PI with Raspbian, because I think the processor is related) will most likely not work, unless you configure it to build a huge statically linked binary.

Hello Sebastian, thanks for replying
What I did for crosscompiling was using the script for installing DTN from sources, which is in http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/source. I modified it to point the toolchain of my openwrt configured for the broadcom target. The cross-compilation of ibr succeeded, I didn't get any error at all, I have done it before for another platform without error. But maybe as you say, I'm missing something for OpenWRT
Concerning to IBRDTN build root recipes for OpenWRT I wasn't aware of them, therefore, if I wanted to make use of such a recipes, may you briefly describe how to incorporate them to OpenWRT buildroot?
Thanks in advance,
Regards

Hello,
You did not specify exactly how you cross-compiled, but I guess your build is broken. Unfortunately there is much more to cross-compiling than just choosig the right architecture.
libm.so normally contains basic math functions, which defintely are available on your plattform "somehow", however maybe they are in your uclibc (or glibc which are you using?) and not seperately or you might need to statically link them. At least it sounds like maybe you accidentally linked with a host library instead of the target, or your cross-compiling environment did not match the target.
There are buildroot (which is used by OpenWRT) recipes for all IBR-DTN components, which you can find here
https://github.com/ibrdtn/ibrdtn/tree/master/recipes/buildroot
If your build has not been created with buildroot you should try to make this work first. If it is, maybe describe what you needed to change to make it compile.
Just using "any" toolchain that targets the processor (e.g. using a toolchain for A PI with Raspbian, because I think the processor is related) will most likely not work, unless you configure it to build a huge statically linked binary.

2014-03-24 12:13 GMT-04:00 Francisco Cuesta ndarkness@gmail.com: Hello IBR staff,
I was wondering whether you have available a version of ibr dtn openwrt
packages for broadcom 2708 chipset, it is based on arm architecture, quite similar to raspberri pi.
I have seen here
http://trac.ibr.cs.tu-bs.de/project-cm-2012-ibrdtn/wiki/download#OpenWRTrepo... that you mention the possibility to find different architectures in your jetkins builder, however, I could find any reference to broadcom architecture there.
Therefore, I tried to crosscompilie ibr dtn from source aiming to that
architecture and with openwrt as OS. I got the daemon, libraries and binaries, but now I get the following error when trying to start the daemon itself.
root@OpenWrt:~# dtnd dtnd: error while loading shared libraries: libm.so.0: cannot open
shared object file: No such file or directory
Did I miss to include some library when crosscompiling? Or I am missing
it on my openwrt OS? In such a case, what libraries should I install?
Thanks in advance,
Regards!

I have checked out that the library is there and I have found it

and on my openwrt the library is present as well root@OpenWrt:/lib# ls -la | grep libm -rwxr-xr-x 1 root root 615996 Mar 22 2014 libm-2.15.so lrwxrwxrwx 1 root root 12 Mar 22 2014 libm.so.6 -> libm-2.15.so

Hallo Francisco,
you have build your packages using OpenWrt based on the eglibc library. But default OpenWrt images (available from the website) are based on uclibc instead. That means your binaries are linked against the wrong c library and you need to switch to a OpenWrt system which is also based on eglibc or switch to a toolchain based on uclibc. I recommend the latter case.
Kind regards, Johannes

I will change the toolchain to uclibc and try again, I will let you know the outcome.

Hello Francisco,
did you do a "make clean" after you configured the toolchain to use uclibc instead of eglibc? If not, do it now and start-over. If that still does not work start with a fresh copy of OpenWrt.

It looks like you have disabled pthreads somehow. Try do get rid of any custom setting for the OpenWrt toolchain and just use the default configuration plus those options you really need. "Advanced configuration options" should be disabled for standard builds.

I noticed your error is form compiling dtnping. Are only the tools failing? Did the daemon or ibrcommon get build? In that case maybe your architecture just needs some more linker flags to find pthreads. You could try in the ibrdtn-tools recipe adding
+libpthread
to the DEPENDS flag in the define Package/ibrdtn-tools section or try experimenting with
TARGET_LDFLAGS += -lpthread
in the tools recipe.

I noticed your error is form compiling dtnping. Are only the tools failing? Did the daemon or ibrcommon get build? In that case maybe your architecture just needs some more linker flags to find pthreads. You could try in the ibrdtn-tools recipe adding
+libpthread
to the DEPENDS flag in the define Package/ibrdtn-tools section or try experimenting with
TARGET_LDFLAGS += -lpthread
in the tools recipe.

Hello Francisco,
did you do a "make clean" after you configured the toolchain to use uclibc instead of eglibc? If not, do it now and start-over. If that still does not work start with a fresh copy of OpenWrt.
Kind regards, Johannes

Hello, I achieve to compile ibrdtn-tools for my architecture and create the packages. I think it was a problem with the change of toolchain and I also included the TARGET_LDFLAGS suggested by Sebastian.
However now, when I install the package I am prompted this dependency, but I cannot find such a library in openwrt packages though.
root@OpenWrt:~# opkg install ibrdtn-tools_0.10.0_brcm2708.ipk Installing ibrdtn-tools (0.10.0) to root... Collected errors: * satisfy_dependencies_for: Cannot satisfy the following dependencies for ibrdtn-tools: * libarchive * * opkg_install_cmd: Cannot install package ibrdtn-tools.

Hello,
libarchive is a new dependency for IBR-DTN tools to get rid of the hidden dependency to a full-features tar.
Your reported error message seams to be inconsistent, because the dependency to libarchive was introduced with the latest release 0.12.0 and your package has the version 0.10.0. I suggest you use the recipes available in GIT repository with the release tag 0.12.0.
https://github.com/ibrdtn/ibrdtn/tree/release/0.12.0/recipes/openwrt
The recipe for the libarchive package is also available in the repository.
Kind regards, Johannes Morgenroth

Hi, looking the ouput I have seen this

Hi,
That library is not needed for OpenWRT. It is only used for (normal) Linux systems.
