Make a number of changes to the OS/2 build. Submitter's comment below.
PR: 732
Submitted by: Ilya Zakharevich <nospam-abuse@ilyaz.org>
Submitter's comment:
This patch:
a) Introduces a new file os2/backwardify.pl.
b) Introduces a new mk1mf.pl variable $preamble. As you can see, it may
be used also to move some OS-specific code to VC-CE too (the the
first chunk of the patch);
c) The DESCRIPTION specifier of the .def file is made more informative:
now it contains the version number too. On OS/2 it is made conformant
to OS/2 conventions; in particular, when one runs the standard command
BLDLEVEL this.DLL
one can see:
Vendor: www.openssl.org/
Revision: 0.9.7c
Description: OpenSSL: implementation of Secure Socket Layer; DLL for library crypto. Build for EMX -Zmtd
[I did not make Win32 descriptions as informative as this - I'm afraid to
break something. Be welcome to fix this.]
d) On OS/2 the generated DLL was hardly usable (it had a shared initialized
data segment).
e) On OS/2 the generated DLLs had names like ssl.dll. However, DLL names on
OS/2 are "global data". It is hard to have several DLLs with the same
name on the system. Thus this precluded coexistence of OpenSSL with DLLs
for other SLL implementations - or other name clashes. I transparently
changed the names of the DLLs to open_ssl.dll and cryptssl.dll.
f) The file added in (a) is used to create "forwarder" DLLs, so the
applications expecting the "old" DLL names may use the new DLLs
transparently. (A presence of these DLLs on the system nullifies (e),
but makes old applications work. This is a stopgap measure until the
old applications are relinked. Systems with no old applications do not
need these DLLs, so may enjoy all the benefits of (e).)
The new DLLs are placed in os2/ and os2/noname subdirectories.
g) The makefiles created with os2/OS2-EMX.cmd did not work (some mysterious
meaningless failures). The change to util/pl/OS2-EMX.pl uses the
variable introduced in (b) to switch the Makefiles to SHELL=sh syntax.
All these backslashes are removed, and the generated Makefiles started to
work.
h) Running os2/OS2-EMX.cmd now prints out what to do next.
