1. Download the source code: https://github.com/guanzhi/GmSSL/
2. Download and install perl and nasm: https://www.perl.org/get.html , https://www.nasm.us/ . nasm sets the path of the running file to the environment variable.
3. Install the latest version of Visual Studio: https://visualstudio.microsoft.com/zh-hans/vs/
4. Generate a makefile: perl Configure VC-WIN64A, or specify the gmssl installation directory with the --prefix= parameter, and --openssldir= specify the openssl path.
5. Compile: nmake
6. Installation: nmake install
7. Problems encountered:
(1) A problem with perl
Modify the D:\Perl64\site\lib\ActivePerlConfig.pm file and comment out the implementation code in the corresponding function body:
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) Unresolved external symbols EVP_get_ciphernames, EVP_get_digestnames
Add the following code to the end of the GmSSL-master\crypto\evp\names2.c file:
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";
}
