Requirement details for native (Visual C++) builds
--------------------------------------------------
+ In addition to the requirements and instructions listed in INSTALL,
+ this are required as well:
+
- You need Perl. We recommend ActiveState Perl, available from
http://www.activestate.com/ActivePerl.
You also need the perl module Text::Template, available on CPAN.
- Please read README.PERL for more information.
+ Please read NOTES.PERL for more information.
- You need a C compiler. OpenSSL has been tested to build with these:
PREFIX: %ProgramFiles%\OpenSSL
OPENSSLDIR: %CommonProgramFiles%\SSL
+ ALSO NOTE that those directories are usually write protected, even if
+ your account is in the Administrators group. To work around that,
+ start the command prompt by right-clicking on it and choosing "Run as
+ Administrator" before running 'nmake install'. The other solution
+ is, of course, to choose a different set of directories by using
+ --prefix and --openssldir when configuring.
GNU C (Cygwin)
--------------
required. Run the installers and do whatever magic they say it takes
to start MSYS bash shell with GNU tools and matching Perl on its PATH.
"Matching Perl" refers to chosen "shell environment", i.e. if built
- under MSYS, then Perl compiled for MSYS is highly recommended.
+ under MSYS, then Perl compiled for MSYS must be used.
Alternativelly, one can use MSYS2 from http://msys2.github.io/,
which includes MingW (32-bit and 64-bit).
