使用GDB/Emacs debug C++程序 Date: 2006-09-26 Version: 1.0 Authors: 张乐 内容 gdb使用技巧 注意事项 准备工作 运行 设置断点 检查状态 继续运行 信号 与Emacs配合使用 gdb使用技巧 注意事项 gdb使用 Readline 库 可以使用bash快捷键，tab补齐 清除inputrc里有冲突的设置 准备工作 重新编译安装程序。系统里现有的程序一般不适合直接拿来跟踪。需要使用合理的CFLAGS重新编译安装后再跟踪。 ./configure find -name "Makefile" | xargs sed -i -e 's/^CFLAGS = /CFLAGS = -g3 -ggdb3 -gdwarf-2 /' make && make install 运行 启动gdb a. gdb bayonne b. gdb --args bayonne -vvv script.scr 利用帮助 a. help 命令类别名 b. help 命令名 运行程序 a. r[un] b. r[un] -vvv script.scr 设置断点 按照函数名设置断点 b[reak] main b[reak] 'namespace::Class::func()' 按照文件名和行数设置断点 b[reak] methods.cpp:523 检查状态 检查堆栈 b[ack]t[race] up down 检查当前函数的源代码 list 检查/改变变量值 p[rint] var p[rint] ptr->mem p[rint] *ptr p[rint] ('namespace::Class') *this p[rint] (('namespace::Class') *this)->a.b.c p[rint] var=value 检查类 ptype ptr set print object on whatis ptr 检查并启用/禁用断点 set breakpoint pending on info b[rea

According to my own experience, scim 1.4.4 works fine with glibc 2.5! Scim 1.4.5 must have used something which is changed from glibc 2.4 to 2.5.

I am not sure about the cause at this moment. Thanks to fcitx, I still can input Chinese. However I can't get used to it, there is some difference between the two input methods. For example in fcitx you need to press 2 keys when switching between English/Chinese, while in scim you just need to press "shift", which is the same as in MS Pinyin. Updates: Anyway, I have come back to scim (1.4.4). So good bye to fcitx! http://zhllg.blogspot.com/2006/10/latest-news-on-scim-and-glibc.html

I have been translating GWN to Simplified Chinese with my teammates since May 2006. Originally, I sent translated GWN to gwn-feedback. Several weeks ago I started to send to neysx, because neysx will be my mentor. At the beginning, I sent translated GWN via email. However, the attachment was lost several times. Then I began to use bugs.gentoo.org. Neysx gave me a link. http://bugs.gentoo.org/show_bug.cgi?id=147686#c4 I was supposed to use this link to assign bugs directly to neysx. I have tried it 3 times. Each time the assignee will be changed from neysx to docs-team. Like this one: http://bugs.gentoo.org/show_bug.cgi?id=150726 However, dev's seem never know this. This explains why words like "Whatever you do, you do it wrong" would come out. Later, neysx verified this fact himself: http://bugs.gentoo.org/show_bug.cgi?id=150743 Then neysx said sorry to me. Problem solved.

I did some housekeeping work today, unmerged glitz. I have disabled glitz USE flag for a long time. Don't know why it still exists today. Of course, I do --depclean regularly. Then disaster happened as you may guess. All the apps previously linked with glitz ceased to work. So I have to resort to revdep-rebuild. However, many program still failed to emerge, as "/usr/lib/libglitz.la" exists in many la files under /usr/lib. Honestly, I still don't know exactly la files' functionality. But I guess it plays an important role in the linking process. I used the following command to wipe out all the "/usr/lib/libglitz.la" string from la files under /usr/lib. sudo find /usr/lib -name "*.la" | xargs sudo sed -i -e 's# /usr/lib/libglitz.la##' Not sure whether this is the right way to go, but it works here.

C-o会和vim里的命令冲突的 所以现在用\\ escape \\\\ 意思是\是命令键，相当于之前的C-a，要打反斜线\就打两个\\ 同理 escape ^Oo 意思是C-o是命令键，C-o o就相当于C-o

https://help.ubuntu.com/community/CompositeManager/AIGLX Information about unsupported hardware The open-source ATI driver (radeon) uses software rendering for alpha (transparency). This makes Compiz unusably slow on a Radeon 9200 (one of the fastest cards supported). No word from ATI on when their proprietary driver (which has proper 3d acceleration) will support AIGLX.

需要有个好的screenrc screen的默认配置的最大问题是ctrl-A和bash里回到行首的快捷键冲突，导致要使用后者要多打一个a(ctrl-a a)。比较麻烦。 下面这个screenrc重定义了这个快捷键 而且加上了一个更漂亮的caption，有日期时间主机名等 现在terminal是否有tab功能对我来说已经无所谓了 哈哈 # ~/.screenrc # use visual bell vbell on # replace ctrl-A by ctrl-O escape ^Oo # set a big scrolling buffer defscrollback 5000 # Set the caption on the bottom line caption always "%{= kw}%-w%{= BW}%n %t%{-}%+w %-= @%H - %LD %d %LM - %c"
