Re: CryptoPkg compiles error: BIO_printf() andBIO_snprintf()redefined.

Hi Qin,
     Got it!
     I thought openssl must be modified before using it as UDK code uses patch tool to handle it before. 
     I try to just unpack openssl then build it, it is OK.
     Thank you.

In general, the user needn’t to run “process_files.pl” to re-generate the INF file, if you are using the latest release (e.g. current 1.1.0e stated in the OpenSSL-HOWTO). 
 
You can re-produce your INF file if any customization requirement (new OpenSSL version, new config flags, …).
 
 
 
Theprocss_files.pl was originally created in UNIX-like style (“#!/usr/bin/perl –w”).
 
So no more validations on those third-party Perl utility (ActivePerl, Strawberry, etc). Of cause, I can take a look at those Perl environments later. 
 
 
 
 
 
Best Regards & Thanks,
 
LONG, Qin

 Hi Qin,
    So currently  our CryptoPkg init does not support third party perl tool such as  ActivePerl ?
    Thanks.

Please check your OpensslLib.inf, the b_print.c should not be there.
And the process_file.pl should filter this file into the final file list in INF.

Use "Perl process_files.pl" is fine enough.
If you are using Windows and installed Git-Windows, just run "perl process_files.pl"
In your Git Bash (Perl should be included in your MINGW environment).
