win10系统编译安装gmssl记录

1.下载源码：https://github.com/guanzhi/GmSSL/

2.下载安装perl和nasm: https://www.perl.org/get.html ，https://www.nasm.us/ 。nasm设置运行文件路径到环境变量。

3. 安装最新版Visual Studio: https://visualstudio.microsoft.com/zh-hans/vs/

4. 生成makefile：perl Configure VC-WIN64A ，或者带--prefix= 参数指定gmssl安装目录, --openssldir=指定openssl路径。

5. 编译：nmake

6. 安装：nmake install

7. 遇到的问题：

（1）perl出现的一个问题

修改D:\Perl64\site\lib\ActivePerlConfig.pm文件，注释掉相应函数体内的实现代码：

my $console;
sub _warn {
#    my($msg) = @_;
#    unless (-t STDOUT) {
#	print "\n$msg\n";
#	return;
#    }

#    require Win32::Console;
#    unless ($console) {
#	$console = Win32::Console->new(Win32::Console::STD_OUTPUT_HANDLE());
#    }
#    my($col,undef) = $console->Size;
#    print "\n";
#    my $attr = $console->Attr;
#    $console->Attr($Win32::Console::FG_RED | $Win32::Console::BG_WHITE);
#    for (split(/\n/, "$msg")) {
#	$_ .= " " while length() < $col-1;
#	print "$_\n";
#    }
#    $console->Attr($attr);
#    print "\n";
}

（2）无法解析的外部符号 EVP_get_ciphernames、EVP_get_digestnames

GmSSL-master\crypto\evp\names2.c文件末尾添加下面的代码：

static void cipher_name_len(const EVP_CIPHER *cipher, const char *from,
	const char *to, void *x)
{
	*((int *)x) += strlen(EVP_CIPHER_name(cipher));
}

static void cipher_name(const EVP_CIPHER *cipher, const char *from,
	const char *to, void *x)
{
	strcat((char *)x, EVP_CIPHER_name(cipher));
}

char *EVP_get_ciphernames(int aliases)
{
	char *ret = NULL;
	int len = 0;
	EVP_CIPHER_do_all_sorted(cipher_name_len, &len);

	ret = OPENSSL_zalloc(len);
	if (!ret) {
		return NULL;
	}

	EVP_CIPHER_do_all_sorted(cipher_name, ret);
	return ret;
}

char *EVP_get_digestnames(int aliases)
{
	return "sm3:sha1:sha256";
}
