Hi!
First of all I figured it out that i should use SHLIB_EX_OBJ not
APP_EX_OBJ :))
Second if I add both uplink.obj and uptable.obj to SHLIB_EX_OBJ then I
cannot link libeay32.dll:
link /nologo /subsystem:console /opt:ref bufferoverflowU.lib
/dll /out:o
ut32dll\libeay32.dll /def:ms/LIBEAY32.def
@C:\DOCUME~1\admin\LOCALS~1\Temp\nm118

Stop.
If I add only uptable.obj then it can create libeay32.dll successfully.
However I cannot link ssleay32.dll. So I figured it out that I do not
need uptable.obj to link ssleay32.dll so I rewrite the ntdll.mak file:
SHLIB_EX_OBJ_SSL=
SHLIB_EX_OBJ_CRYPTO=uptable.obj
and then I modified the end of the mak file to use these variables for
the dlls.
So finally successful to build on amd 64 both statically and
dynamically. Thanks a lot. All tests are also successful.
I summarize here what to modify in the mak files to build on AMD 64:
Remove:
SHLIB_EX_OBJ=
Add:
SHLIB_EX_OBJ_SSL=
SHLIB_EX_OBJ_CRYPTO=uptable.obj
Modify:
CFLAGS= to remove /WX option because of size_t conversations and I also
recommend to use /MT instead of /MD for the static link libraries in
nt.mak file.
LFLAGS=/nologo /subsystem:console /opt:ref bufferoverflowU.lib (so
remove /machine:I386 flag and add bufferoverflowU.lib)
Only in ntdll.mak: MLFLAGS= /nologo /subsystem:console /opt:ref
bufferoverflowU.lib /dll (so remove /machine:I386 flag and add
bufferoverflowU.lib)
Modify the following to use SHLIB_EX_OBJ_SSL instead of SHLIB_EX_OBJ:
$(O_SSL): $(SSLOBJ)
$(LINK) $(MLFLAGS) /out:$(O_SSL) /def:ms/SSLEAY32.def @<<
$(SHLIB_EX_OBJ_SSL) $(SSLOBJ) $(L_CRYPTO) wsock32.lib gdi32.lib
advapi32.lib user32.lib
<<
Modify the following to use SHLIB_EX_OBJ_CRYPTO instead of SHLIB_EX_OBJ:
$(O_CRYPTO): $(CRYPTOOBJ)
$(LINK) $(MLFLAGS) /out:$(O_CRYPTO) /def:ms/LIBEAY32.def @<<
$(SHLIB_EX_OBJ_CRYPTO) $(CRYPTOOBJ) wsock32.lib gdi32.lib
advapi32.lib user32.lib
<<
So how to build on AMD 64 and Intel EM64T I summarize here:
1. perl Configure VC-WIN32
2. ms\do_ms
3. perl ms/uplink.pl win64a > uptable.asm
4. ml64 -c uptable.asm
5. modify the mak files as above
6. nmake -f ms\ntdll.mak
7. nmake -f ms\nt.mak
I used the new platform SDK with 64 bit compiler and MSVC++.
I hope it helps others out.
Thank you for your help,
