Re: X11R7.5 and C.UTF-8

ASCII meets this characteristic, but so does EBCDIC, as well as UTF-8. The C locale also implies that you can manipulate bytes = 128 in the naive manner, so long as you don't care about characters embedded in those bytes. And what do you know - ASCII, EBCDIC, and UTF-8 all meet this property, too. beyond that an implementation can do what it wants. And on Cygwin 1.7, plain C actually does imply UTF-8, which happily is backward-compatible with ASCII. That's an interpretation that so far hasn't been blessed by the standards people. Any discussion of this topic should mention that, as a caveat. Actually, the standards people HAVE spoken - and they agreed with our interpretation. POSIX was INTENTIONALLY written with the intent that a UTF-8 encoding is valid for the C locale, for the same reason that it was written that an EBCDIC encoding is valid for the C locale. These emails from the Austin Group (the folks that write POSIX) are telling: https://www.opengroup.org/sophocles/show_mail.tpl? CALLER=show_archive.tplsource=Llistname=austin-group-lid=12982 This is basically your email on the matter. https://www.opengroup.org/sophocles/show_mail.tpl? CALLER=show_archive.tplsource=Llistname=austin-group-lid=13012 But they also admitted that there is still more work needed in POSIX to make this intent clearly codified (for example, that control characters must be single bytes 128). But they have not actually agreed with you yet. -- Thomas E.

Re: how do I get help if I can't figure out how to do anything?
Have you looked at the troubleshooting documentation? You know you can run with verbose and log options. My guess is that the reason the display can't be opened is made reasonable clear in your log file(s). I'm also going to hazard a guess that your xserver doesn't have opengl support.

If not, then this list is your consultant. If so, then the answer is probably no. It's free software so if you don't understand something then you read the documentation. If the documentation doesn't help then you ask in an appropriate forum and are grateful when someone volunteers time to help you. cgf -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
Re: 1.7 - what's the right way to start X?

There shouldn't be differences between 1.5 and 1.7 here. Now I have gotten startxwin.bat to work, and modified it to run my bash script. I had some strange problems on the way though. Previously, I had used the Cygwin Bash Shell to make some changes. I use mount -c /, change /etc/passwd to refer to right home directory /c/home/fstx, and put in my .profile and .bash_rc files. I don't remember doing the mkpasswd/mkgroup thing, but I could have. When I double-clicked startxwin.bat for the first time, it failed. I think XWin.exe did not start dfor some reason. But I immediately tried again, and this time I got an XTerm. However, I was in /home/fstx, not /c/home/fstx, and I got the mkpasswd message. When I tried to fix things, I discovered that the mount prefix was set back to /cygdrive. I can change it, but when I restart cygwin it goes back to /cygdrive. I can live with that (at least for now) But starting xterms seems to be very slow, and about 25% of time it fails with 2 [main] xterm 3128 fork: child -1 - died waiting for longjmp before initialization, retry 0, exit code 0xC005, errno 11 xterm: Error 29, errno 11: Resource temporarily unavailable Reason: spawn: fork() failed I have seen this problem before, and the solution was to run rebaseall, which broke emacs, and then reinstall libncurses to fix emacs. Is this the way to do it? Will it still break emacs? Will other things break? Will it break again when updating cygwin? I am running Windows 7 64-bit Enterprise. Despite the troubles I have had, I must say that I admire Cygwin for doing a very good job at an almost impossible task, and the developers for the heroic efforts to bring Cygwin to each new version of Windows, despite that Microsoft apparently couldn't care less about breaking it. -- Fredrik Stax\ang | rot13: s...@hcqngr.hh.fr This is all you need to know about vi: ESC : q !

There shouldn't be differences between 1.5 and 1.7 here. 1.7 makes some pretty significant changes on how 'mount' works. Basically, Cygwin 1.7 uses a real fstab file instead of a bunch of registry entries and 'mount' only creates temporary mounts. If you want a permanent mount, use the fstab file. In a little bit more detail, see below. From: http://cygwin.com/1.7/cygwin-ug-net/ov-new1.7.html - Mount points are no longer stored in the registry. Use /etc/fstab and /etc/fstab.d/$USER instead. Mount points created with mount(1) are only local to the current session and disappear when the last Cygwin process in the session exits. - Cygwin creates the mount points for /, /usr/bin, and /usr/lib automatically from it's own position on the disk. They don't have to be specified in /etc/fstab. This discusses the mount table in more detail: http://cygwin.com/1.7/cygwin-ug-net/using.html#mount-table This is the help information for mount under 1.7: http://cygwin.com/1.7/cygwin-ug-net/using-utils.html#mount Thanks. -Jason -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://x.cygwin.com/docs/ FAQ: http://x.cygwin.com/docs/faq/
