 |
|
This is really weird. There are lots of apps I can't run from the command line, but run fine from the desktop menu, or by clicking on icons (using Window Maker). For example, gnumeric and gnomecc give nothing -- I type the command at the prompt, and I get another prompt -- I get no error messages or anything. (Yes, they're on my path. See?)
[sl70@musuko:~] <10:59:48> 508 ->> which gnumeric
/usr/bin/gnumeric
[sl70@musuko:~] <11:06:25> 509 ->> gnumeric
[sl70@musuko:~] <11:06:38> 510 ->>
If I type emacs, abiword or konqueror at the command line, they give segfaults. All these work fine if run from the menu or by clicking on icons. Any ideas about this? |

mabey this will help find out whats going on:
| Code: | emerge strace
strace gnumeric
|
also mabey try another shell, your window manager is probably using /bin/sh, what are you using? mabey your shell is restricting the resources you can use? (ulimit?)
hth,

strace was an excellent idea. I found in the output to strace that all the problematic programs were segfaulting at this point:
readv(3, [{"@locale=ja_JP.SJIS,ja_JP.EUC,ja_"..., 52}, {"", 0}], 2) = 52
munmap(0x40d8d000, 116192) = 0
--- SIGSEGV (Segmentation fault) ---
I know how to fix this (remove export XMODIFIERS="@im=kinput2" from ~/.bashrc), but I don't know why this should be a problem. Also, I would like to keep that line in there so I can use Japanese in various applications. (But I can always include the line in a wrapper script to run those apps.)
Thanks to sa for the help. How do I mod him up? He should be made an apprentice, at least. |

Okay, I think I know what is causing the problem. I think what you are trying to do is run a program with $XMODIFIERS="@im=kinput2" but with the $LANG and $LC_ALL values still set to their default rather than ja_JP (I am able to recreate your exact strace doing this). Most programs require that if you have your input method set to Japanese, you must also have the language of the program set to Japanese, otherwise, it will segfault. So try doing this from the commandline: | Code: | | LANG=ja_JP LC_ALL=ja_JP XMODIFIERS="@im=kinput2" gnumeric |
If that works, I would probably add export LANG=ja_JP and export LC_ALL=ja_JP to your ~/.bashrc. If you want a more detailed description of how to deal with Japanese input in programs, look at my posts here.

Why is this? Am I the only person on the planet that prefers their UI in English, but with the ability to enter Japanese text whenever and whereever I might want? Is there a technical reason why these cannot be decoupled? Does it lie with POSIX locales in general, with X, with a toolkit, or at the application layer?

No idea why, actually. Just something I've kind of noticed before. Would be nice to always have the xim set to Japanese, you know, just in case (especially when I need to search for something on google.co.jp)
