MinGW中的静态链接库 [英] Statically linking libraries in MinGW
问题描述
假设我有三个C源文件.前两个是LIB(lib * .a?)，第三个是使用它们的应用程序.
Suppose I have three C source files. The first two to be LIBs (lib*.a?), and the third is an application which uses them.
第一个是(re.c):
The first is (re.c):
int re(int i) {
return i;
}
第二个是(test.c):
The second is (test.c):
int re(int); // Depends on re.c
int test(int i) {
return re(i);
}
第三个是(main.c):
And the third is (main.c):
#include<stdio.h>
int test(int); // Uses test.c
int main(void) {
printf("%d\n",test(0));
return 0;
}
现在如何创建前两个LIB，使我以后可以将它们与主应用程序静态链接?
Now how can I create the first two LIBs in such a way that allows me to statically link them later with main application?
我知道如何创建DLL并将其动态链接到我的应用程序中，例如:
I know how to create the DLLs and link them dynamically in my application such as:
cc -o re.dll re.c -shared -Wl，-out-implib = libre.a(for re.c)
cc -o re.dll re.c -shared -Wl,--out-implib=libre.a (for re.c)
cc -o test.dll test.c -L. -lre -shared -Wl，-out-implib = libtest.a(用于test.c)
cc -o test.dll test.c -L. -lre -shared -Wl,--out-implib=libtest.a (for test.c)
cc -o main.exe main.c -L. -lre -ltest
cc -o main.exe main.c -L. -lre -ltest
那么，如何在MinGW的可执行二进制文件中创建等效的LIB进行静态链接，以及如何链接它们?
So how to create equivalent LIBs to be statically linked within my executable binary in MinGW, and how to link them?
很明显，在Windows下:)
Obviously, under Windows :)
推荐答案
I found the solution here: http://www.codeproject.com/Articles/84461/MinGW-Static-and-Dynamic-Libraries
想法是编译所有库(源文件)而不链接.然后使用ar rcs -o lib*.a *.o转换输出对象，其中*是创建的对象的名称(一一转换).之后，我们只需使用-L.编译应用程序以指定目录，并使用-l*编译应用程序以指定没有GNU命名修饰的库名称.
The idea being is to compile all libraries (source files) without linking. Then converting the output objects with ar rcs -o lib*.a *.o where * is the name of objects created (converting them one by one). After that, we simply compile the application with -L. to specify the directory and with -l* to specify libraries names without GNU naming decoration.
对于那些依赖于其他库的库，应该先指定它们，然后再引用库，否则当我执行-lre -ltest时会出现诸如undefined reference to re之类的错误，其中-ltest -lre是正确的，因为测试库是指重新库.
For those libs which depends on others, they should be specified first and then the referenced libs, or else errors such as undefined reference to re will occur when I did -lre -ltest, where -ltest -lre is the right one, because test library refers to re library.
这是我的编译方式:
cc -c -o test.o re.c
cc -c -o test.o re.c
cc -c -o re.o re.c
cc -c -o re.o re.c
ar rcs -o libtest.a test.o
ar rcs -o libtest.a test.o
ar rcs -o libre.a re.o
ar rcs -o libre.a re.o
cc -o main.exe main.c -L. -ltest -lre
cc -o main.exe main.c -L. -ltest -lre
它也适用于Tiny C编译器.
It also works for Tiny C Compiler.
