黑莓的没落是注定的

因为太不在意客户需求了

电量低到一定程度就不能用无线电,哎我就奇怪了,一般用户可能都是想无线电开到直接断电为好,无线电不能用,开着手机干什么呢?黑莓你们是为什么要这样设定系统功能,谁定义的,真是太奇怪了,电话打到一半,手机还开着,电话不能打,接收验证码,收到一半(好险还都收了)信号断掉,请问黑莓这种情况下,要这个手机作甚?手机是工具,不是TM你们是随意做决定的

黑莓必须要没落

[出差前老婆给了几百块,想不到几天就花了,想不起来哪里花的,正在想呢,自言自语中]

我:打的花了40,车票来回140.。。。。。。还差300啊。。。。怎么花的。。。。。应该也没掉啊。。。。。。

我:哦~~~~!

沉默了几秒

老婆:你哦啥,你肯定是去吃了个金钱豹,花了300,这就对上了

undefined reference to `SetDIBitsToDevice@48′

from [1]一样的问题, 添加后解决
Hello,Recently I’ve downloaded Code::Blocks because I’d like to make projects that are open and multi platform. I want to make a very simple program that uses the C image liberary CImg.
The whole library is included in a single header called :CImg.h”. I’ve included this in the same folder as my project I wish to work on. I have also included the header file in my source code for the project.

The minimum code contained in my main.cpp file looks like this:

#include"CImg.h"usingnamespace cimg_library;int main(){constunsignedchar purple[]={255,0,255};CImg<unsignedchar>(640,400,1,3,0).draw_text(100,100,"Hello World",purple).display("My first CImg code");return0;}

Upon compiling I get the following errors:


obj\Release\main.o:main.cpp||undefined reference to `SetDIBitsToDevice@48'|
obj\Release\main.o:main.cpp|| undefined reference to `SetDIBitsToDevice@48'|
obj\Release\main.o:main.cpp|| undefined reference to `SetDIBitsToDevice@48'|
obj\Release\main.o:main.cpp||undefined reference to `SetDIBitsToDevice@48'|
obj\Release\main.o:main.cpp|| undefined reference to `SetDIBitsToDevice@48'|
obj\Release\main.o:main.cpp|| more undefined references to `SetDIBitsToDevice@48' follow|||===Build finished:6 errors,0 warnings ===|

I’m not used to really working much with external dependencies with Code::Blocks and I’ve not ventured beyond playing with SFML (which I got working following a tutorial).
I’m working on Windows 7 at the moment if that is of any help. I’m not advanced with C++ but I have an understanding of the core library. Adding dependent libraries is really a headache it seems…

Although I don’t know CImg, undefined reference normally means you haven’t linked something properly.Meaning, either it’s not there (under more options in build options), in the wrong order or the library files is not in the places where you have specified. (MinGW compiler library folder or somewhere else on your hard drive).

Sometimes, particularly with things like Qt4 and Java, you may need to setup Environmental Variables under Advanced Properties in Computer; this is for in folders other than the MinGW library folder.

A quick search on Google (SetDIBitsToDevice) revealed that you need to link with libgdi32.a (assuming MinGW). Under Build Options – Linker Settings – Link Libraries, add gdi32.

Thank you SO much!
Working now!

What is a general rule of thumb process when adding a new library to a project?
It seems that no two libraries share exactly the same steps…

Rule of thumb: Include as few headers as possible, and link as few libraries as possible :wink:As mentioned, most “undefined reference to SomeFunction@XX” are linker errors (the value XX indicates how many bytes of parameters it expects), and if you do not know which library it is defined within, you will just have to search (Google is your friend) or look in the source. Chances are, you are not the first to ask this question, or it will be documentated somewhere online, as the aforementioned function were on MSDN.

When you want to use a new library, you have usually read an article/tutorial about it, so you will know what functions/classes to use, which basic headers to include and which libraries to link with. The latter is only an option when someone have been so kind as to compile them for you – otherwise this you will also have to do yourself (can be a bit tricky if you also have to guess the compiler and linker parameters).
Now, whether you have read about its usage or not, it is always a good thing to get an overview of the library’s general structure, since no two libraries are the same (as you have discovered). This will also give you an understanding of its usage and a clue as to how it works internally (can be useful when strange errors start to pop up). Just a quick look through the API Reference (Doxygen) or similar will usually do (heck, even scanning the main “include” directory reveils a lot about its structure if the headers are properly named).

C++ undefined reference to WinMain@16 (Code::Blocks)

同样的问题,

http://stackoverflow.com/questions/21500724/c-undefined-reference-to-winmain16-codeblocks

解决方案为

Try this: Settings->Compiler, click the tab Build options, select the checkbox

Explicitly add currently compiling file’s directory to compiler search dirs

P.S.

Next time when you create a new class, in the File policy section, make sure you select checkboxes

  • Add path to project
  • Header and implementation file shall be in same folder

However, do NOT select

Use relative path

叶:你就没想过为啥打折?

我:反正我不是你那种金耳朵,没差别

叶:差评攒到5000终于可以打!折!啦!
