Hallo Everyone, I am building a component in Sierra Wireless studio using Legato 18.09 for WP77-WP77XX and every time I get this Error: “Legato builder: \*\* ERROR: INTERNAL ERROR: Trying to get target info ‘N6target20LinuxComponentInfo\_tE’, which is not set for the current target” and sometimes I get another error “lexing error”. Could you please help me out figuring out the problem? Thanks ---

I have built the helloWorld project successfully, but there is a differnce here because in my project I am trying to build only the component using mkcomp and not the app using mkapp. I have realized that when I try to change the target platform from Legato 18.09 for WP85-WP77XX to Legato 18.09 for WP77-WP77XX the error of \*\* ERROR: INTERNAL ERROR: Trying to get target info ‘N6target20LinuxComponentInfo\_tE’, which is not set for the current target" disappears and is replaced with the “lexing error” one. When I try to know what produces the lexing error exactly I can see it is in the auto-generated makefile “target: $(MKCOMMAND)” ninja: error: Component…/Target\_Legato\_Debug/build.ninja:82: lexing error ---

I don’t see problem with mkcomp in DS: ![image](https://us1.discourse-cdn.com/flex019/uploads/legato1/original/2X/f/f2334aa0692f16b852fd772b91af0e5d806bfde2.png) ---

But still couldn’t figure out what does this mean \*\*\*\* ERROR:\*\* **INTERNAL ERROR: Trying to get target info ‘N6target20LinuxComponentInfo\_tE’, which is not set for the current target.** **Makefile:37: recipe for target ‘target’ failed** ---

what is making this error? Can you port your component to helloworld component to understand this? ---

I have found the error. Part of it was because I am using the wrong toolchain wp85 instead of wp77 and the other part was becuase an environment variable was not set. Thanks a lot for your support and help
