Totally stuck installing software

Hello there,

i’m totally stuck at installing third party software on my digi linux device.

I’m using the ConnectCard™ for i.MX28 with 256/256 and the Development Kit.

I successfully compiled a linux with Digi ESP and transferred it on my module via network and serial. In the past i had gcc and g++ on my modules. Now its not installed on the module.

Looking for a download i’m scarred how big the gnu compiler actually is. To big for 256mib space.

So any hint how to install extern software mit configure/make/make install on my device.

I guess i have to cross compile or something or to include it in my Digi ESP Linux Kernel project.

I understood that there is the possibility to place the application in the “app” directory. But its not simple as it is i guess. I get a lot of errors and stuff. The chapter 4.2.4 is very short and did not help at all.

yes, you need to cross-compile on host.
start shell on a host, setup environment for cross compiler:
export PATH=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi/bin:$PATH
export TOOLCHAIN_DIR=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi/

If your application supports auto-configure, call ./configure:

CC=arm-linux-gcc ./configure --host=arm-linux --target=arm-linux --prefix=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi

run make:
make CC=arm-linux-gcc

Here is an example:
export PATH=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi/bin:$PATH
export TOOLCHAIN_DIR=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi/

wget http://www.tcpdump.org/release/tcpdump-4.3.0.tar.gz
wget http://www.tcpdump.org/release/libpcap-1.3.0.tar.gz
tar xvfz libpcap-1.3.0.tar.gz

cd libpcap-1.3.0/
CC=arm-linux-gcc ./configure --host=arm-linux --target=arm-linux --prefix=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi --with-pcap=linux
make CC=arm-linux-gcc
make install

cd …
tar xvfz tcpdump-4.3.0.tar.gz
cd tcpdump-4.3.0/
vi configure
Find in configure and change ac_cv_linux_vers=unknown to ac_cv_linux_vers=2

CC=arm-linux-gcc ./configure --host=arm-linux --target=arm-linux --prefix=/usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi
make CC=arm-linux-gcc
make install

Now everything is installed in the directory /usr/local/DigiEL-5.9/x-tools/arm-unknown-linux-gnueabi.

I guess now i have to copy the created folders to my rootfs projekt? But there are many directorys. How do i know, what to copy? sbin and lib directorys into my rootfs?

do “make install” in to some temp folder then you will know what belongs to your project
