Compiler for CFA 910

[jdmulloy]

Can anyone give me guidance on setting up a compiler for the CFA 910? I found that gcc wasn't installed by default on the CFA 910, I'll try installing it from the package manager. Are there any instructions for setting up a cross compiler?

I managed to install the gcc package through opkg but it doesn't provide a "gcc" command. I tried compiling a Hello World program with "arm-angstrom-linux-gnueabi-gcc" but it complains about not being able to execute cc1. Are there other packages I need to install to get this to work?

Greetings,

GCC does not come installed on the CFA-910. We customarily do not compile right on the CFA-910. Usually we use a cross-compiler as built from the Angstrom tool chain on a host computer.

You can build you tool chain by following the Angstrom build instructions at:
https://www.crystalfontz.com/forum/showthread.php?t=6813

This will rebuild all the tools for building for the CFA-910 (including cross-compilers) as well as its applications and libraries.

You may have some luck with pre-built opkgs. From what you have said, it sounds like you may need another gcc package to provide the c backend compiler or to set up the links and/or paths for the toolchain.

We have the tool chain built and we are able to compile basic C programs, but I can't figure out how to compile a GTK application. We've been using the compiler in "angstrom/tmp/cross/armv5te/bin" and it's been working but I'm not sure that is the correct way to compile things. Are there any instructions on the right way to compile programs for the CFA?

I figured out how to get compile GTK program and I have been able to compile and run a GTK application on the CFA.

Here's my Makefile in case anyone else needs to figure this out in the future.

PATH=/data/angstrom/tmp/cross/armv5te/bin:/data/angstrom/tmp/sysroots/i686-linux/bin:/data/angstrom/tmp/sysroots/i686-linux/usr/bin:$PATH

vpath %.h ./inc
vpath %.c ./src

all: gtk_fe.arm

gtk_fe.arm:
	arm-angstrom-linux-gnueabi-g++ -Wall -I ./inc `pkg-config --cflags --libs gtk+-2.0 | /bin/sed s/i686-linux/armv5te-angstrom-linux-gnueabi/g` -L/data/angstrom/tmp/sysroots/armv5te-angstrom-linux-gnueabi/lib ./src/main.cpp -g -o gtk_fe.arm
	
clean: 
	rm gtk_fe.arm
