RE: [ECOS] HOW TO compile and include thirdparty libray.

["Ramesh Chandra Satyavaram" <rameshcs at danlawinc dot com>]

Hi Thomas,

Thanks for your mail.
I understand the following from your response.

a. Build the ecos.
b. Using the ecos and the compilation tool (arm-elf which is used to build 
	the ecos ) compile the third party application. This could be a
'.o' 
	file with out linking.
	
c. Finally link the customer supplied '.o' file or  with the application.

Are these steps correct?


Thank you,
Rmaesh Chandra.

Yes, they should build using the same toolchain and include tree (from your
eCos kernel build tree) as you use to build the kernel.

Try looking at this example:
http://www.mlbassoc.com/examples/build_httpd.html
It shows how to build an eCos application using a separate library/module.
This
particular example is self contained, but it should show you how to do it
with
your customer's library.
