主题: Re: Cannot execute application on ARM target

Yes, I built the IOC application via the EPICS templates:

    makeBaseApp.pl -t example armexample

    makeBaseApp.pl -i -t example armexample ( the architechture choose linux-arm, and the application name is armexample)

I didn't change any configuration of the application, and then MAKE is no error. So I copy the <appTop> to the target.

when I try to start the application on the target,   ../../bin/linux-arm/armexample st.cmd,    the Error is: 

-bash: ../../bin/linux-arm/armexample: No such file or directory 

and then I change to the <appTop>/bin/linux-arm/, chmod +x armexample, and ./armexample, the Error is:

-bash: ./armexample: No such file or directory 

I didn't known what to do next, please give some advices, thanks a lot!

Subject: Cannot execute application on ARM target

 

Hi,
I am trying to build EPICS application on ARM target, and the cross compiling on host have no error,
but the IOC on the target cannot execute:
    -bash: ./armexample: No such file or directory 

============================================================================================

[Ernest]:

If you are building  your IOC application via the EPICS Templates, then executable is found here by default:

<TOP>/bin/<T_A>/armexample

For example, I built and application called "Jupiter" for a linux target:

<TOP>/bin/rhel6-x86_64/Jupiter

Please provide more information such as did you first create a skeleton for you app with:

makeBaseApp.pl -t example
============================================================================================

########################################################
my configuration as following:
    HOST: Ubuntu 14.04 (on VMware)
    TARGET: Exynos4412
    BASE: base-3.14.12.5
    GCC: arm-none-linux-gnueabi-gcc-4.4.1

the cross compiling configuration is:   
    configure/CONFIG_SITE:
        CROSS_COMPILER_TARGET_ARCHS=linux-arm
        CROSS_COMPILER_HOST_ARCHS=linux-x86
        SHARED_LIBRARIES=NO
        STATIC_BUILD=YES
    configure/os/CONFIG_SITE.Common.linux-arm:
        #COMMANDLINE_LIBRARY = READLINE
    configure/os/CONFIG_SITE.linux-x86.linux-arm:
        GNU_DIR = /opt/armtoolchain/arm-2009q3
        GNU_TARGET = arm-none-linux-gnueabi
########################################################

the .bashrc configuration is:
    export EPICS_HOST_ARCH=linux-x86 
    export EPICS_BASE=/home/control/epics/base-3.14.12.5
    export LD_LIBRARY_PATH=/opt/armtoolchain/arm-2009q3/lib:$EPICS_BASE/lib/linux-arm

I am still getting the error message on target, Please solve my above query. 

Thanks
