Sorry, I mean why is it "/usr" on Linux.<br>
<br>
Another question, the user manual says in the prefixes section:<br>
<br>
"A further reason not to use the standard prefix is to allow more than one version of RTEMS to exist on your host machine at a time. The autoconf and automake tools required by RTEMS are not versioned and vary between the various versions of RTEMS. If you use a single prefix such as the standard prefix there is a chance parts from a package of different versions may interact. This should not happen but it can."<br>
<br>
I think this is quite inconvenient from RSB to use such a prefix. Why can't it use OS standard prefix (e.g. "/opt" or "/usr/local") + rtems + version, e.g. "/opt/rtems/5" by default? You still have the root permission problem, but the we get rid of the conflicting versions stuff.<br></blockquote></div></div><div dir="auto"><br></div><div dir="auto">That's essentially what I always do. /opt is a very old convention I remember using on Solaris. Texlive installs there. Personally, I would recommend /opt/rtems/version or something off a home directory that is similar. Again, personally, I create a directory $HOME/rtems-XXX/tools/version where XXX indicates a project or purpose. I add nothing to my PATH until I commit to working in that RTEMS instance. This let's me keep normal work separate from new class instances away from customer project instances.</div><div dir="auto"><br></div><div dir="auto">Forn5heb</div><div dir="auto"><br></div><div dir="auto"><br></div><div dir="auto"><div class="gmail_quote"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
