Hi Erik,

My apologies for the mixup. I'm glad to hear you got it running, but since you use bsdlib (not libmodem), you should consider downloading libsupl v0.6.1.

We recently updated the text on our website, specifically for libsupl:

If you use bsdlib, the latest compatible version of libsupl is 0.6.1. For libmodem usage, you should use v0.7.0 or newer

Kind regards,

Håkon

Hi Håkon,

I used version 1.4.0 of nrf and version 0.7.0 of the supl library. I also tried to nrf version 1.4.2 but with the same result.

I do think that the supl lib is where the problem comes from indeed:
target_link_libraries(${SUPL_CLIENT_TARGET} INTERFACE modem -lc)

Removing the modem dependency from the interface in CMakeLists.txt makes it compile again.

Thnx,

Erik

Which version libsupl are you using? With master, ie. the name change of bsdlib to libmodem; you need to use libsupl v0.7 or newer. You can download it from our website by re-applying here:
