The attached patch is to the latest 2.4/arch/i386/config.in to correct a problem that we saw after I integrated 4.0.1-3 from the 3/19 CVS tree. The diffs are for the current CVS version. Please take a look at the description and let me know if this makes sense. Another item from the Configure.help, to define help for the CONFIG_DUMP_COMPRESSION entries, reword as appropriate. --- /tmp/Configure.help Thu Apr 4 18:58:51 2002 +++ /tmp/Configure.help.new Thu Apr 4 19:00:17 2002 @@ -3675,6 +3675,16 @@ program to open up /dev/dump to perform dump configuration.

One deficit, some logic changed in that the values for the compression variables could be "y" | "m" | "n", where in the original if CONFIG_DUMP were "y" then the values for compression could have only been "y" | "n", not "m"; this is not an problem if CONFIG_DUMP is "m". If this is an issue we could add logic to catch and fix this case, but for now they should have appropriate default values (i.e. matching CONFIG_DUMP). Does this work as you understand it needs to, Vamsi? Let me know and if so I'll submit it for TLT 1.1 and to the lkcd mailing list.

Subject: RE: [CarrierLinux Developer] Configure problem DUMP_COMPRESS I just looked at the latest CVS tree on sourceforge.net/projects/lkcd and we match the latest CVS version for 2.4/arch/i386/config.in. This is a bug and needs to be fixed, I'll take a look at getting it fixed and submit a fix back to the lkcd mailing list. Dave Howell -----Original Message----- From: Vamsi Krishna S .

Subject: Re: [CarrierLinux Developer] Configure problem DUMP_COMPRESS These CONFIG options are from LKCD. Look for "elif" construct in arch/i386/config.in and replace it with fi;if. This was fixed some time ago in the LKCD cvs. I don't know which version of LKCD you are using but you need to something similar to: - elif [ "$CONFIG_DUMP" = "m" ]; then + fi + if [ "$CONFIG_DUMP" = "m" ]; then -- Vamsi Krishna S.
