无法在Solaris 10 SPARC上编译Ruby 2.5.1

Question

我试图在Solaris 10 SPARC上编译Ruby 2.5.1，结果出现以下错误。不知道为什么我会得到套接字的未定义符号。

有人可以帮忙吗？

看起来像the source code中的一个错误。 parse_numeric_port()仅在未定义GETADDRINFO_EMU时定义，但如果定义了parse_numeric_port()，则代码使用GETADDRINFO_EMU（请注意我的注释添加到代码中）：

#ifndef GETADDRINFO_EMU
struct getaddrinfo_arg
{
    const char *node;
    const char *service;
    const struct addrinfo *hints;
    struct addrinfo **res;
};

#ifdef HAVE_INET_PTON
static int
parse_numeric_port(const char *service, int *portp)
{
    unsigned long u;

    if (!service) {
        *portp = 0;
        return 1;
    }

    if (strspn(service, "0123456789") != strlen(service))
        return 0;

    errno = 0;
    u = STRTOUL(service, NULL, 10);
    if (errno)
        return 0;

    if (0x10000 <= u)
        return 0;

    *portp = (int)u;

    return 1;
}
#endif

static void *
nogvl_getaddrinfo(void *arg)
{
    int ret;
    struct getaddrinfo_arg *ptr = arg;
    ret = getaddrinfo(ptr->node, ptr->service, ptr->hints, ptr->res);
#ifdef __linux__
    /* On Linux (mainly Ubuntu 13.04) /etc/nsswitch.conf has mdns4 and
     * it cause getaddrinfo to return EAI_SYSTEM/ENOENT. [ruby-list:49420]
     */
    if (ret == EAI_SYSTEM && errno == ENOENT)
    ret = EAI_NONAME;
#endif
    return (void *)(VALUE)ret;
}
#endif  // *** This closes #ifndef GETADDRINFO_EMU ***

static int
numeric_getaddrinfo(const char *node, const char *service,
        const struct addrinfo *hints,
        struct addrinfo **res)
{
#ifdef HAVE_INET_PTON
# if defined __MINGW64__
#   define inet_pton(f,s,d)        rb_w32_inet_pton(f,s,d)
# endif

    int port;

    // *** But this uses parse_numeric_port() even if it wasn't defined ***
    if (node && parse_numeric_port(service, &port)) {
    static const struct {
        int socktype;

你可以找到一种在构建时没有定义GETADDRINFO_EMU的方法，或者你可以提交bug报告并等待修复。
