errors reported by gpm under mc and aumix when using Eterm (b/liblow.c(376)]:)

From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4.1) Gecko/20031030 Description of problem: When, on fedora C1, you compiled Eterm, then run mc, instead ot the hint line you read a message like: "b/liblow.c(376)]:" when you run aumix, it's even worse you read: " 16333 write(2, "*** err [lib/liblow.c(267)]:\n", 29) = 29 16333 write(2, "strncmp/isdigit/option.consolena"..., 41) = 41 16333 write(2, "*** err [lib/liblow.c(376)]:\n", 29) = 29 16333 write(2, "Oh, oh, it\'s an error! possibly "..., 39) = 39 " This error doesn't happen when you run those programs under xterm. So i searched through all my libs for that liblow message and found out it was in libgpm. Something must be wrong there. This error happens also when gpm is *not* running. Version-Release number of selected component (if applicable): gpm-1.20.1-38 mc-4.6.0-6 aumix-2.8-6 How reproducible: Always Steps to Reproduce: 1. Download, --rebuild & install http://www.eterm.org/download/libast-0.5-1.src.rpm 2. Download, --rebuild & install http://www.eterm.org/download/Eterm-0.9.2-1.src.rpm 3. run Eterm 4. under Eterm run mc or aumix, read the error Actual Results: Errors are shown on the program launch, doesn't hurt in mc, but screen is scrambled in aumix Expected Results: No errors. Additional info: I couldn't dig it more out, i don't really see the relation between gpm & those other software, i'm open to any hint. Also couldn't find anybody else with the same setup, but i assume it happens everywhere.
Created attachment 95853 [details] strace -f aumix -o aumix.log search for 'liblow.c' message
i forgot to mention, Eterm requires imlib2, this lib was installed using apt-get & freshrpms.net url: ftp://freshrpms.net/pub/freshrpms/fedora/linux/1/imlib2/imlib2-1.1.0-1.fr.i386.rpm ftp://freshrpms.net/pub/freshrpms/fedora/linux/1/imlib2/imlib2-devel-1.1.0-1.fr.i386.rpm
This error doesn't appear when using the previously compiled Eterm with gpm-1.19.3-27 gpm-devel-1.19.3-27 from redhat9 on fedC1. So i confirm it's a problem somwhere in gpm.
gpm has been specifically compiled to have enhanced mc support, which is different from previous versions. It shouldn't be outputing debugging diagnostic though. The diagnostic messages would appear because the libgpm is still used even though gpm is not running. To clarify, if the debugging output is removed, both progs behave as expected? How does mc work inside of other terminals such as gnome-terminal?
aumix and mc works fine under xterm and gnome-terminal (nothing printed or shown in strace), this happens only in the homecompiled Eterm. I've searched through the src.rpm (and thus the source code too) to disable libgpm output, i've only found where it was used: src/lib/report-lib.c seems to be the code that prints the error on the screen (on stderr), but there are no switch to disable it. So i tried this: aumix 2>/dev/null indeed the printed errors on stderr aren't visible anymore, but, disabling the errors shouldn't really fix them? :)
I'm getting the same error under the following circumstances: - when connecting from Putty. Error written by mc and links (2.1pre13). Other programs not tested. - on text console when programs are executed from mc. Error written by links, aumix, pinfo. Doesn't matter if gpm is started or not.
I comfirmed that I encountered the same problem in FC1, I use dialog, but the output message contains (check bug #109468) ---------------------------------------------------- *** err [lib/liblow.c(267)]: strncmp/isdigit/option.consolename failed *** err [lib/liblow.c(376)]: Oh, oh, it's an error! possibly I die! 3 ---------------------------------------------------- while in RH9 dialog works very well. How can I fix this ?
Adding write permissions to /dev/gpmctl fixes the problem.
Adding write permissions to /dev/gpmctl does NOT work for me... I change the permission of my /dev/gpmctl permission to be srwx-w--w- 1 root root 0 Jan 31 11:19 /dev/gpmctl= Both root and normal user run "dialog" will still produce the ---------------------------------------------------- *** err [lib/liblow.c(267)]: strncmp/isdigit/option.consolename failed *** err [lib/liblow.c(376)]: Oh, oh, it's an error! possibly I die! 3 ---------------------------------------------------- in my tmp file, where only "3" is what I want. Thanks.
Sorry, I was too quick. Write permissions on gpmctl fixes only aumix (and only if aumix is not run from mc).
Make this on the shell: export TERM=eterm To go Up and Down in mc use ctrl-n and ctrl-p!
fixed with latest gpm against fc2
