创建静态库并使用prefake连接到它 [英] Creating static library and linking to it with premake
问题描述
我目前正在尝试学习如何使用premake 4,以便将其应用于OpenGL sdk 。我目前正试图做一个Visual Studio 2010解决方案构建2个项目,一个是静态库,另一个包含一个主要的源文件,与主要方法。
I am currently trying to learn how to use premake 4 in order to apply it to the OpenGL sdk. I am currently trying to make a Visual Studio 2010 solution that constructs 2 projects, one being a static library, the other contains a single main source file, with the main method.
这个项目非常简单,仅用于学习预习的目的。在静态库项目中,名为Test,我有2个文件,Test.h和Test.cpp。 Test.h包含方法print()的原型。 print()只是打印一行到控制台。使用premake,我将静态库链接到Main项目,并且在main.cpp中包含了Test.h文件。我的问题是这样:在VS2010我得到这个错误时,我试图构建:
This project is extremely simple, and is solely for the purpose of learning premake. In the static library project, named Test, I have 2 files, Test.h and Test.cpp. Test.h contains the prototype for the method print(). print() simply prints a line to the console. Using premake, I linked the static library to the Main project, and in main.cpp I have included the Test.h file. My problem is this: in VS2010 I get this error when I attempt to build:
1>main.obj : error LNK2019: unresolved external symbol "void __cdecl print(void)" (? print@@YAXXZ) referenced in function _main
1>.\Main.exe : fatal error LNK1120: 1 unresolved externals
这是我的代码在4个文件,preake4.lua:
Here is my code in the 4 files, the premake4.lua:
solution "HelloWorld"
configurations {"Debug", "Release"}
project "Main"
kind "ConsoleApp"
language "C++"
files{
"main.cpp"
}
configuration "Debug"
defines { "DEBUG" }
flags { "Symbols" }
configuration "Release"
defines { "NDEBUG" }
flags { "Optimize" }
links {"Test"}
project "Test"
kind "StaticLib"
language "C++"
files{
"test.h",
"test.cpp"
}
Test.cpp:
#include <iostream>
void print(){
std::cout << "HELLO" << std::endl;
}
Test.h:
void print();
Main.cpp:
#include <conio.h>
#include "test.h"
int main(){
print();
getch();
return 0;
}
如果你想知道为什么有一个getch控制台立即关闭一旦它到达返回0,所以我使用getch()来解决这个问题,这迫使窗口等待,直到用户按下另一个键。任何关于这个问题的建议将是美好的,因为我只是不知道什么问题是。如果它是简单的,请不要阉割我,我对预制和静态库非常少的经验,这就是为什么我想学习他们。
If you are wondering why there is a getch() there, on my computer the console immediately closes once it reaches return 0, so I use getch() to combat that issue, which forces the window to wait until the user has pressed another key. Any advice on this issue would be wonderful, because I simply am not sure what the problem is. If it is something simple please dont castrate me on it, I have very little experience with premake and static libraries, which is why I am trying to learn them.
推荐答案
links {"Test"}
Lua不是Python。空格与Lua无关,就像空格对C ++无关紧要。因此,您的链接
语句仅适用于发布
配置。如果你想把它应用到项目作为一个整体,它需要在配置
语句之前,就像你的 kind
, files
和其他命令。
Lua is not Python. Whitespace is irrelevant to Lua, just like whitespace doesn't matter to C++. So your links
statement only applies to the "Release"
configuration. If you want it to apply to the project as a whole, it needs to go before the configuration
statement, just like your kind
, files
, and other commands.
Premake4以这种方式工作,只用于Release
构建(或Debug或其他)。实际上,您可以在配置
下放置几乎任何 项目
因此,您可以具有仅在调试版本中使用的特定文件,或任何其他文件。
Premake4 works this way so that you could have certain libraries that are only used in a "Release"
build (or Debug or whatever). Indeed, you can put almost any project
command under a configuration
. So you can have specific files that are used only in a debug build, or whatever.
