alpinelinux环境下编译出错

[sanqi]

在 ipdb.h里加上 typedef unsigned char u_char; 才能编译通过

在 ipdb.h里加上 typedef unsigned char u_char; 编译也不能过

不知道还能不能得到作者的更新

@xiaoyawl 在 ipdb.h 加的位置是在 ipdb_reader; 和 int ipdb_reader_new(const char *file, ipdb_reader **reader); 之间，试了可以编译，你可以再试试，确保 alpine 装了 json-c-dev,修改后大概是这样：

typedef struct ipdb_reader {
    ipdb_meta_data *meta;
    int v4offset;
    int file_size;
    int data_size;
    unsigned char *data;
} ipdb_reader;

typedef unsigned char u_char;

int ipdb_reader_new(const char *file, ipdb_reader **reader);
