re: VS9中C++少得可怜的更新 pass86 2007-07-12 21:55
用VS是用的它的IDE,一些库,如MFC,这是我看中的,至于编译器,我还是看中GCC,
re: mutable的用法 pass86 2007-07-11 12:53
mutalbe是否是是标准的关键字呢?在GCC中编译不过去。
re: subversion安装配置记录 pass86 2007-07-06 23:00
在WINDOWS下怎么配置呢?TortoiseSVN在WINDOWS下的。
估计PFnCreateObject creatorFuncTable[MAX_TYPE_ID];因该是
PFnCreateObject* creatorFuncTable[MAX_TYPE_ID];

搞定,原来是我用的vsvars32.bat应该在一个控制台下完成,因为它只在当前控制台中设置的环境变量生效。
LIB下生成了216个项目,1.2G。
re: boost1.34.0编译日志 pass86 2007-06-07 14:00
bjam "sTOOLS=vc-7_1" --prefix=D:\Boost install
编译中无法找到windows.h
完成结果
...failed updateing 244 targets...
...skiped 228 targets...
...updated 1022 targets...
WHY?
LIB文件夹下有102个项目。

我编译了一次1.33.1,只是复制了些头文件到我的目标我的文件架,没有生成。LIB文件,是怎么回事情呢,用的是。NET 2003选项,能够给我发个
。NET2003的编译明命令行吗,谢谢。

恩,是个知识点,细致入微,
学到了。
你俩都学C++阿。

re: 有一类程序员 pass86 2007-05-22 17:40
其实每个人不是一生下来就是高手。
这样的人我到遇到。
还是应该虚心学习。
不知道.a文件做什么的,在boost中看到,偶孤陋寡闻。
由此看来是库文件。
re: GUI程序也能使用控制台窗口 pass86 2007-05-09 17:06
VC6.0编译错误:
console.cpp(72) : fatal error C1010: unexpected end of file while looking for precompiled header directive
但是用其它IDE能编译成功,为什么呢?
这个东西真的挺有用的,DEBUG时用,不用MessageBox那么麻烦了。
re: 如何实现UI pass86 2007-05-08 13:49
UI的设计愈来愈重要,它能增强用户的体验,但是用过很多软件後发现,单纯的用图片来做UI并不大吸引人,有点死板。
Picasa2的UI做的就很好啊,用户的体验很好,不知怎么做的,貌似用了OPENGL。
