Hello All, Has anyone come across this error before? [GEN] imx6_net.cdl While forming CapDL spec: failed to find dataport symbol 'camkes router router_send_buf data' in ELF router_group_bin make[1]: *** [imx6_net.cdl] Error 255 make[1]: *** Deleting file `imx6_net.cdl' make: *** [imx6_net] Error 2 Thanks, Chris Guikema
I was able to figure out the issue. Having the CONFIG_USER_LINKER_GC_SECTIONS removes a lot of the dead code, however it also removed a lot of code that was actually needed to run the system. Thought I'd post the fix if anyone in the future comes across that issue.

Hi Chris, Sorry for not replying earlier, but glad you found a solution. Can I ask if you're using a particular version of CAmkES, or the tip of master? We noticed this problem previously on CAmkES a bit after adding that configuration option, but thought we fixed it. So curious if this is from an older version of CAmkES, or if we didn't fix it properly. Adrian On Fri 19-May-2017 6:16 AM, Chris Guikema wrote: I was able to figure out the issue.

Adrian,
I am using a slightly modified version of the CAmkES tool that was started from commit cf42782f99fd7f16b88995aaabfc68c23d9e3122, which should be the newest commit on the master branch.
If it helps, I am using the seL4MultisharedData connector.

Hi Chris,
Looks like the seL4MultiSharedData template didn't get updated. It's missing a call to `keep_symbol` in the template. See https://github.com/seL4/camkes-tool/blob/next/camkes/templates/seL4SharedDat... in the seL4SharedData template. Something similar should be at https://github.com/SEL4PROJ/global-components/blob/next/templates/seL4MultiS... (and on the -to side of the template).
Attached a patch that you should be able to use until fix goes in.
Adrian
