Hi Joel; 




BTW RTEMS uses GNU autotools differently in that it configures in one 
folder/directory and the builds targets into another folder is a very rare way 
of using autotools. I know this because I have downloaded and reviewed over 
5000 open source projects for my new book. 



Funny because the core GNU tools like gcc, binutils, gdb plus newlib all allow 
out of tree builds. 

It may be rare to use it this way but it works and leaves your source directory 
with no build artifacts. 

It also allows having multiple builds from the same source tree simultaneously. 

It's not an indictment of the RTEMS use of GNU Autotools that you build out of 
the configured folder. I am not sure why stating a truth may be offensive? 

It was never a touchy point I was making, it was that for the purposes of 
debugging you can't use the online advice that people suggest to fix RTEMS 
configuration problems because the "build setup" 
(configuring in one folder, bulding targets in another) is not the TYPICAL way 
OTHERS use the GNU Autotools. So file finding in PATH searching works with 
different options.

Most GNU autotools projects configure IN THE FOLDER that they want to compile 
and archive source code. That's one reason why the problems of diagnosing RTEMS 
build configurations are harder.

This is not required for autotools. It is just the default instructions. 

When I read this I first thought I was talking to Richard Stallman. (LOL)

Setting explicit file locations with absolute directories is a way to 
workaround the problems. 


Cheers!
