gcc编译zlib和minizip生成压缩文件到zip格式的程序

下载 https://www.zlib.net/zlib-1.3.1.tar.gz 并保存到 /par
然后解压缩

tar xf zlib-1.3.1.tar.gz
cd /par/zlib-1.3.1
./configure
make

就在/par/zlib-1.3.1目录下生成了libz.so.1.3.1等动态库，libz.a静态库及minizip等示例程序。

如果要单独编译minizip，也可到 /par/zlib-1.3.1/contrib/minizip目录下执行make。

假如有一个自己调用zlib和minizip的源代码test_zip.c，

#include "zlib.h"
#include "zip.h"
 
int main() {
    zipFile zf = zipOpen("example.zip", APPEND_STATUS_CREATE);
    if (!zf) {
        // 处理错误...
    }
 
    int err = zipOpenNewFileInZip(zf, "file_to_compress.txt", 
                                   NULL, NULL, 0, NULL, 0, NULL, 
                                   Z_DEFLATED, Z_DEFAULT_COMPRESSION);
    if (err != ZIP_OK) {
        // 处理错误...
    }
 
    FILE *file_to_add = fopen("file_to_compress.txt", "rb");
    if (!file_to_add) {
        // 处理错误...
    }
 
    char buffer[1024];
    int len;
    while ((len = fread(buffer, 1, sizeof(buffer), file_to_add)) > 0) {
        zipWriteInFileInZip(zf, buffer, len);
    }
    fclose(file_to_add);
 
    zipCloseFileInZip(zf);
    zipClose(zf, NULL);
    return 0;
}

可这样编译并执行：

gcc test_zip.c /par/zlib-1.3.1/contrib/minizip/zip.c /par/zlib-1.3.1/contrib/minizip/ioapi.c -L /par/zlib-1.3.1 -o test_zip -I /par/zlib-1.3.1/ -I /par/zlib-1.3.1/contrib/minizip -lz

在当前目录下，造一个file_to_compress.txt文件，然后./test_zip即可。
注意这个文件静态编译了minizip的相关代码，但动态链接系统libz.so。
如果要把zip相关文件全静态链接，这样写

gcc test_zip.c /par/zlib-1.3.1/contrib/minizip/zip.c /par/zlib-1.3.1/contrib/minizip/ioapi.c -L /par/zlib-1.3.1 -o test_zips -I /par/zlib-1.3.1/ -I /par/zlib-1.3.1/contrib/minizip /par/zlib-1.3.1/libz.a

即把-lz改成静态库的路径。

可以用ldd命令来查看依赖的动态库，可见test_zips已经没有对libz.so.1的依赖了。
