I also just wanted to follow-up that for this particular project, you<br>
will need to be able to build newlib and produce patches for it. I<br>
suggest you do that during the proposal-writing period. Also, make<br>
sure your mentor approves all patches that are intended for newlib<br>
BEFORE you post to their mailing list. We had some issues in the past<br>
when student patches were not in a great shape, and the newlib folks<br>
got a little upset about having to do a lot of work that was really<br>
the responsibility of an RTEMS Mentor.<br></blockquote><div><br></div><div>Yes, I have successfully build newlib-cygwin,</div><div>by following steps from blog of Aditya <a href="https://adityupa.wordpress.com/">https://adityupa.wordpress.com/</a></div><div>and as I have created git-patches before, for RTEMS, so I guess <br></div><div>I will have no problem creating patch for newlib. I just need to get <br></div><div>familiar with their code-formatting styles, comment-formatting style,</div><div>commit-formatting styles etc.</div><div><br></div><div>Thanks</div><div>Vaibhav Gupta<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
