[yocto] SDK generation issue

[Jim Rafert]

Try doing:

${CC} test.c

This will invoke the cross compiler with all the compilation flags required to produce
an executable for the target, using libraries on the target root file system.

Hi Paul Eggleton,
Thanks for your help in the solving the issue for adding the bsp to yocto.
Now I am working on the yocto sdk generation.

I am generated the yocto SDK using the yocto sdk script "bitbake core-image-minimal -c populate_sdk" command. With this command I am able to generte the installation script file and .manifest file.

I run the installation script file. After running installation script file it propts that following message:

Extracting SDK...done
Setting it up...done
SDK has been successfully set up and is ready to be used.


After this i run the ". /opt/poky/1.7/environment-setup-mips32rel-poky-linux" and echo $PATH i got the correct path.

After this i built wrote a small example and try to build with the sdk generated toolchain by running following command:

mipsel-poky-linux-gcc test.c

but i got the following errors:
