Hi,
I am in the process of porting the OpenSSL libs to compile using the Watcom C/C++
compiler and the WASM assembler. I will be supporting OS/2 & Win32 perhaps 32-bit DOS
if there is demand for it. I will also be producing a version of OpenSSL that will
compile on OS/2 using the EMX+GCC environment. I would like to see this incorporated
into the OpenSSL distribution.
What is the best way to incorporate code changes? For C source code changes I can make
use of the following predefined macros:
__EMX__ EMX Specific Changes
__WatcomC__ Watcom Specific Changes
__OS2__ OS/2 Specific Changes
The Win32 ASM code seems to work for the most part. Watcoms WASM uses a slightly
different calling convention though. This can be addressed but require the ASM
function prototypes to add cdecl:
extern int myfuntion(void);
would be:
extern int cdecl myfunction(void);
I also noticed that the WASM does not like part of the SHA1-586.ASM code. It seems
that sha1_block_asm_host_order code is inside of the sha1_block_asm_data_order code.
By moving this code outside of the data_order code the ASM code compiles fine.
Should I just add the cdecl to the prototypes (wraped in #ifdefined __WatcomC__) or
should the perl code be modified (this would require help from someone with better
perl & asm experience)?
Also some advice would be appreciated on how to handle eliminating the use of the
Configure scripts and shell scripts as these are not appropriate for this environment.
Is there a list of the various compile time flags used for building the OpenSSL libs?
What *.h files are autogenerated?
Is there a list showing the dependencies between the various modules?
tks,
PS: What was the reason for moving all the sha1 code from the *.c file into the *.h
file?
