I am trying to implement a json-c library as an application and I have a problem with the glibc version. This is the toolchain I am using for the wp77xx (FX30S) /opt/swi/SWI9X06Y_02.32.02.00/sysroots/x86_64-pokysdk-linux/usr/bin/arm-poky-linux-gnueabi This is instead the repo for the json-c libra…

I don`t know what is included in the image for this fs, but when I make the folders and copy the libc.so.6 into the tmp_lib, then run the overlay command I get this error: root@fx30s:/tmp# mount -t overlay overlay /lib -o lowerdir=/lib,upperdir=/tmp/tmp_lib,workdir=/tmp/tmp_lib_wr; root@fx30s:/tmp…

maybe you also need to copy the ld-linux.so.3: owner@owner-ThinkPad-X220:~/Downloads$ find /opt/swi/SWI9X07Y_02.28.03.01/sysroots/armv7a-neon-poky-linux-gnueabi/ -name “ld-linux.so.3” /opt/swi/SWI9X07Y_02.28.03.01/sysroots/armv7a-neon-poky-linux-gnueabi/lib/ld-linux.so.3 owner@owner-ThinkPad-X220…

mmmhhh… It doesnt seems we are getting anywhere here, maybe the best option at this point is to rebuild the image of my target with all necessary libraries, which I would have preferred to do at a later stage but I dont see any alternative if I want to move forward…

To me, no idea why your /lib/libComponent_handleJSONComponent.so will require a GLIBC lib that is not present on your toolchain. I wonder if you are using the correct toolchain path to compile your app… Anyway, good luck!

well, I don`t know either, this was the reason why I posted on this forum… :slight_smile: The problem is certainly the toolchain, which is building the app with a newer Glibc library then what is included in the firmware. The only toolchain I can find is the one from this link: https://source.sie…

that is the firmware not the toolchain, correct?

it includes the toolchain, legato framework, images.

I have been working with a manual installation of the legato workspace and that could have been the problem, I was more looking to replace and re-install the toolchain still working merely under legato but I can use leaf instead. The problem I have is that after installing the leaf: XXXX@XXXX-Virt…

you can type “export” to check if the toolchain path is correct after you do “. bin/configlegatoenv” e.g. [image]

you can search by “leaf search” and then you will see a identifier "swi-fx30-catm_1.0.0 "
