How do you compile OpenSSL for x64?

Question

After following the instructions in INSTALL.W64 I have two problems:

• The code is still written to the \"out32\" folder. I need to be able to link to both 32-bi

Answer 1

I solved the problem this way, using the 1.0.1c source:

Add this block to util/pl/VC-32.pl, just before the $o='\\'; line.

if ($debug)
    {
    $ssl .= 'd';
    $crypto .= 'd';
    }

Add this block to util/pl/VC-32.pl, just before the if ($debug) line.

if ($FLAVOR =~ /WIN64/)
    {
    $out_def =~ s/32/64/;
    $tmp_def =~ s/32/64/;
    $inc_def =~ s/32/64/;
    }

Then build all varieties:

setenv /x86 /release
perl Configure VC-WIN32  --prefix=build -DUNICODE -D_UNICODE
ms\do_ms
nmake -f ms\ntdll.mak

setenv /x64 /release
perl Configure VC-WIN64A --prefix=build
ms\do_win64a.bat
nmake -f ms\ntdll.mak

setenv /x86 /debug
perl Configure debug-VC-WIN32  --prefix=build -DUNICODE -D_UNICODE
ms\do_ms
move /y ms\libeay32.def ms\libeay32d.def
move /y ms\ssleay32.def ms\ssleay32d.def
nmake -f ms\ntdll.mak

setenv /x64 /debug
perl Configure debug-VC-WIN64A --prefix=build
ms\do_win64a.bat
move /y ms\libeay32.def ms\libeay32d.def
move /y ms\ssleay32.def ms\ssleay32d.def
nmake -f ms\ntdll.mak
