Hello all,

I downloaded the latest version of the linux ditribution (Legato-Dist-Source-mdm9x15-SWI9X15Y\_07.04.06.00.tar.bz2) and tried to compile that version initially.

My host is a Ubuntu 12.04.5 native linux system and from my point of view the tool environment matched to the version I want to compile.

Unfortunately I get an error:

Does anybody know what went wrong?

When I am compiling the version matching to the release 15.08 the yocto project is building.

Best regards

WP710x module is no more supported and must be removed from the build.

Edit the following file;  
meta-swi/meta-swi-mdm9x15/conf/machine/swi-mdm9x15.conf  
And remove “wp7” from the list of Legato targets:  
LEGATO\_ROOTFS\_TARGETS ?= “ar7 ar86 wp85”

Then do “make clean” followed by “make” to rebuild everything.
