Please bear with me as I'm new to Minix and may be bringing up old news ! Scenario: using elvis (via vi link), while in input mode I get an "Alarm", dropping me back to a prompt (PS1), but I'm locked up, no input other than F1, F2, or ALT+CTL+F9 gets any response. So I A+C+F9 back to a login prompt and try to return to my vi session; a. vi says that the file is busy b. virecover says that there is no elvt123E0302 file to recover c. in /usr/tmp there is a elvt123e0302 file (note the lower case e) d. if I "mv elvt123e0302 elvt123E0302" virecover will find the file and all is well. So I assume that there is a problem with elvis creating the tmp file with a %x format, while virecover is constructing the name using %X, but when I examined the code for virecover.c and tmp.c I found that they both use the format from the header file which uses the lower case %x. I continued on down to the doprintf.c library code which appears OK, but I rebuilt it anyway to no avail. I then wrote a one-liner C program that prints out a hex value with %x and %X - guess what ? They both print out the same - upper case A-F! I think that the version of elvis that I have was perhaps compiled under a different compiler which supports the %x vs. %X distinction, as it apparently cannot be compiled under Minix as yet, while virecover was compiled with the native library code. Bottom line: I don't know how to migrate the library code to MS-DOS to re-compile elvis, so I can't change elvis to use upper case hex, and re-compiling virecover doesn't help as I seem to have library code that doesn't support lower case hex. Any suggestions ? -- This space for rent. |David Gavin - Amdahl Corp. - Boston, MA | drg50@juts.ccc.amdahl.com
