Subject: CryptoPkg compiles error: BIO_printf() and BIO_snprintf() redefined.
Date: Thu, 13 Apr 2017 10:39:03 +0800	[thread overview]

Hi experts,
     Now I compile CryptoPkg in lastest UDK, I find there is a build error:
  
 BaseCryptLib.lib(CrtWrapper.obj) : error LNK2005: BIO_snprintf already defined i
n OpensslLib.lib(b_print.obj)
BaseCryptLib.lib(CrtWrapper.obj) : error LNK2005: BIO_printf already defined in
OpensslLib.lib(b_print.obj)
d:\project\udkapp\udkapp\Build\WinddyPkg\RELEASE_DDK7600\X64\WinddyPkg\Dxe\Crypt
Dxe\CryptDxe\DEBUG\CryptDxe.dll : fatal error LNK1169: one or more multiply defi
ned symbols found 
  
     Both c file "CryptoPkg\Library\BaseCryptLib\SysCall\CrtWrapper.c" and c file "CryptoPkg\Library\OpensslLib\openssl\crypto\bio\b_print.c" defined function BIO_printf(), BIO_snprintf().
  
     I just remove the dummy functions in  CrtWrapper.c, the build process is successful. 
 Is that right?
  
     BTW, I think someone maybe does not know how to run perl script for openssl library init,  so I write down my trying steps under windows 7 64 bit for your reference:
 1. download and install ActivePerl-5.24.1.2402-MSWin32-x64-401627.exe
2. cmdline run "ppm install dmake"
3. download openssl-1.1.0e.tar.gz and unpack it to CryptoPkg/Library/OpensslLib/openssl.
4. rename "openssl\Configure" to "openssl\Configure.pl"
5. modify file process_files.pl line 49:  "./Configure" -> "Configure.pl"
6. under cmdline, cd to "CryptoPkg\Library\OpensslLib" and run "process_files.pl"
  
     Thank you.
