i686 vs Pentium 4

Eugene Tucker:
Bitbucket will not let one access your Seamonkey and Thunderbird builds as well, The seem to have shut down the page.

Dave Yeo:
Did you try at https://bitbucket.org/dryeo/cc-os2/downloads/, it is the page I created when Bitbucket deleted all the repositories using Mercurial.
Also Firefox is at [url]https://bitbucket.org/dryeo/mozilla-os2/downloads//url]
Seems our old builds don't work there anymore, I had to use the simplebrowser to access.

Dariusz Piatkowski:
Dave,


--- Quote from: Dave Yeo on March 12, 2022, 05:02:20 am ---...The output of -Q --help=target is interesting too. Something like,

--- Code: ---gcc -march=native -Q --help=target > march_native.txt
gcc -march=sandybridge -Q --help=target > march_sandybridge.txt
diff -u march_native.txt march_sandybridge.txt

--- End code ---

Hmm...OK, this simple gcc call does NOT work on my machine...which perhaps implies I have something else wrong? lol

Here is what I get (I won't post the whole thing, but it's about 200 lines of the same repeated error message until the very end):

At first I thought maybe this was a session related thing...so I even tried bash, but same result.

Any idea what my gcc is choking on here???

Dave Yeo:
Perhaps picking up an OS/2 command instead of a *nix command? My PATH starts with (W: is UNIXROOT) W:\usr\libexec\bin and I also had to move \os2\print.com out of the way. Look in popuplog.os2 for print.com or similar crashes. My output starts with,
