Try adding _alloca_probe_16 and _ftol2_sse to pal\win32\rotor_pal.src.
The best place to do that is right below the existing "_alloca_probe"
line.

Subject: Re: [DOTNET-ROTOR] Building Rotor with VS 2005 Beta 2

i'm stuck building the pal rt. It seems that my rotor_pal.dll has not
been
built 100% correctly. Its missing some functions. Like alloca I guess.
Can
you tell me what does this error means while I'm building the pal rt:

why is alloca unresolved? I read in the docs that its been deprecated. I
need suggestions on this one. My

hint was something to do with _MSC_VER define checks that are in so many
places but I'm not sure. Does the

following gives any hint? :


#ifdef _MSC_VER
#define alloca _alloca
#else
#define _alloca alloca
#endif //_MSC_VER

PALIMPORT void * __cdecl _alloca(size_t);

Its inside the rotor_pal.h. Also look at win32pal.h.


Btw remember in my earlier post I mentioned the ctime() error that the
"build" tools's source code was

giving and I commented the code to make the build work? Well I resolved
that. I was looking at the exports

(generated by dumpbin on msvcr80d) that it did not contain definition
for
ctime. I saw that rotor_pal.def contains (after preprocessing)
ctime = msvcr80d.ctime
but since it was not in the exported function by msvcr80d so I looked
for
one that had it and I found

crtdll.dll and added the a new macro called NOTLOGGEDCRTAB in
\sscli\pal\win32\rotor_pal.src
......
#if DBG
#define PALEXPORT(x) x = PAL_##x
#define PALEXPORTCRT(x) x = PAL_##x
#define PALEXPORTOLE(x) x = PAL_##x
#define PALEXPORTUSER(x) x = PAL_##x
#define PALEXPORTSOCKET(x) x = PAL_##x
#define NOTLOGGED(x) x = KERNEL32.##x
#if _MSC_VER == 1310
; Changes neccessary to build and run against VS7.1.
; In order to run against the 7.0 runtime modify this
; against MSVCR70D
#define NOTLOGGEDCRT(x) x = MSVCR80D.##x
#else
#define NOTLOGGEDCRTAB(x) x = crtdll.##x <-------- notice this
#define NOTLOGGEDCRT(x) x = MSVCR80D.##x
#endif
#else
.......

and replaced
NOTLOGGEDCRT(ctime)
with
NOTLOGGEDCRTAB(ctime)

Now I uncommented the source code that was using ctime() and it compiled
and
build fine.
