Question

我正在尝试编译oauth-utils http://mir.dnsalias.com/oss/oauth/start 适用于Ubuntu的Windows。我以前在Windows上编译过它（几个月前），但想尝试交叉编译。

我使用mingw32确定openssl build，然后放入 libssl.a和libcrypto.a在正确的位置。链接器现在找到这些库（耶！）但我收到以下错误：

任何可能导致此问题的想法？

感谢。

Answer 1

与Gdi32.lib链接

Answer 2

您正在尝试编译哪个版本的OpenSSL？一般来说，我发现版本1.0和更新版本的MinGW-W64工作得很好。例如，参见OpenSSL cross-compilation for Windows教程。

Answer 3

似乎如果删除了

之间的所有内容

static void readscreen(void)
{
#if !defined(OPENSSL_SYS_WINCE) && !defined(OPENSSL_SYS_WIN32_CYGWIN)

和

#endif /* !OPENSSL_SYS_WINCE */
}

在rand_win.c中，该建筑有效。我不是100％确定如何安全地删除它。

Answer 4

您是否在链接命令中添加-mwindows？

使用OpenSSL for Windows进行交叉编译
