Getting Error while running make command

[mharis]

Hi all,
I am new to Red Pitaya, I am trying to run digital_led_blink.c program but as soon as I run make command, I am getting this error.

Code: Select all

 make digital_led_blink
gcc -g -std=gnu99 -Wall -Werror -I../../api/include -L ../../api/lib -lm -lpthread -lrp    digital_led_blink.c   -o digital_led_blink
/usr/bin/ld: cannot find -lrp
collect2: error: ld returned 1 exit status
<builtin>: recipe for target 'digital_led_blink' failed
make: *** [digital_led_blink] Error 1

Kindly help me out with this issue.

Have you done "make api" previously ?

[mharis]

Yes, on that too i am getting error. Even though I have followed the same instructions as mentioned on GitHub. What could be the reason?
Can you share some simplified steps to execute this program?

Best Wishes

Are you doing this on the Red Pitaya or on some other machine ? If it's another machine, you need to set it up to use the linaro toolchain (as described in the github README).

I didn't understand your question properly. Definitely, I want to run it on Red Pitaya board. But as mentioned on GitHub firstly I have to make digital_led_blink file and then copy it to red pitaya using scp command. The issue in my case is "make" is not working neither "make api" nor "make digital_led_blink file". So what could be the issue?

P.s I have Linux Ubuntu 14.04 in my PC.

To add further, on GitHub these steps are mentioned to install ARM Tool Chain:

TOOLCHAIN="http://releases.linaro.org/14.11/compon ... ihf.tar.xz"
curl -O $TOOLCHAIN
sudo mkdir -p /opt/linaro
sudo chown $USER:$USER /opt/linaro
tar -xpf *linaro*.tar.xz -C /opt/linaro

So in my case curl -O command has no effect,it is not working. I believe it should download this release from the given link. Also tar command is also throwing error.
As an alternative what i did is that I manually downloaded the required file and extract it to /opt/linaro folder. Is it a right approach? Because in my case these given commands are not working.

I guess you have to call make CROSS_COMPILE=arm-linux-gnueabihf- or set export CROSS_COMPILE before in bash.
The curl command didnt work for me, too. I had to install in manually. Bes sure it's the hard floated version and add the bin directory (where arm-linux-gnueabihf-gcc is located) to your PATH-variable.

And of course you have to make api in RedPitaya/ directory before trying to build the examples. (again with CROSS_COMPILE)

[mharis]

Hi,
Can you share please the steps to compile and execute any ".c " file, given in Examples/C on Git-hub. It has been two days and I am unable to execute anything on RedPitaya.

Download Vivado 2015.4 (License is "WebPack" or something like that). You can download everything or just Vivado WebPack and the SDK. There is also a vivado downloader which installs the components you want. Install to /opt/Xilinx. Add /opt/Xilinx/Vivado/2015.4/bin and /opt/Xilinx/SDK/2015.4/bin to $PATH.
run
sudo chown -R $you:$you /opt/Xilinx (maybe -r instead of -R)
sudo apt-get install libc6-dev-armel-cross
sudo apt-get install build-essential

Download arm-linux-gnueabihf 4.9 2011.4 manually
sudo mkdir -p /opt/linaro
sudo chown $you:$you /opt/linaro
unpack the downloaded arm-linux.. archive to /opt/linaro
add /opt/linaro/gcc-linaro-4.9-2014.11-x86_64_arm-linux-gnueabihf/bin to $PATH (third directory may differ)

go to your RedPitay directory in shell
run make CROSS_COMPILE=arm-linux-gnueabihf- api
go to Examples/C in shell
run make CROSS_COMPILE=arm-linux-gnueabihf- all

Maybe you have to clone the project again. I had some trouble building the api after a failed attempt. Hope that helps

Thanks alot, I am going to try this. Will post the results here. once again thanks.
