Hi all
Greg Stark: I'm sure that you gave the right solution, so I tried doing as
you said.
For starters I just added "no-dh no-dsa" to remove DH and DSA asymmetric
ciphers.
Unfortunately when compiling, this gave the following error:
cl /Fotmp32\ssl_cert.obj -Iinc32 -Itmp32 /MT /W3 /WX /G5 /Ox /O2 /Ob2 /Gs0
/GF /
Gy /nologo -DWIN32 -DWIN32_LEAN_AND_MEAN -DL_ENDIAN -DDSO_WIN32 -DBN_ASM
-DMD5_ASM -DSHA1_ASM -DRMD160_ASM /Fdout32 -DNO_DSA -DNO_DH -c
.\ssl\ssl_cert.c
ssl_cert.c
.\ssl\ssl_cert.c(274) : error C2220: warning treated as error - no object
file generated
.\ssl\ssl_cert.c(274) : warning C4102: 'err' : unreferenced label
NMAKE : fatal error U1077: 'cl' : return code '0x2'
Stop.
After looking in the source, my guess is that when NO_DH is defined, no code
ever does a "goto err". Apparently VC++ does not like to have a label that
no one ever uses.
It would be great if some of the OpenSSL developers would comment on this.
Maybe we are doing it the wrong way?
Any other ideas..... anyone?
Thanks,
Kim Hellan

Emne: Re: How to reduce size of OpenSSL LIB file
Kim,
You can modify the do_masm.bat file in the ms\ directory. You need to
tell the perl script util\mk1mf.pl which cryptogrpahy to eliminate. Here is
a fragment that could be in do_masm.bat showing one way to do it.
SET SKIPS=no-rc5 no-bf no-cast no-idea no-ripemd no-dh no-dsa
perl util\mk1mf.pl %SKIPS% VC-WIN32 >ms\nt.mak
Look through the perl script and maybe a few other places to see what no-***
options are supported. Please post the results to the list. I think it is of
general interest.
Good luck,
