[Ggnfs-devel] VC++ Builds

[Brian G. <br...@gl...>]

Hi All,

Over the last few days, with help from Sten and Anton, I have been
tidying up the VC++ build projects for VC++.  The ggnfs builds for VC7
and VC8 (beta) are now in pretty good shape but it has not proved
possible to obtain a good build for VC6 because this compiler lacks
support for features that many of the GGNFS source files now take for
granted.

I have not run VC6 for several years and have only been able to support
this build by translating the VC7 build files into VC6 format. Sten has
VC6 installed but he has not been able to obtain a working build and
feels that this is not something that he can afford to invest time in.

Hence we either need to drop the VC6 build or find someone who still
wants this build and is prepared to repair and maintain it.  If there
are no volunteers over the next few days, the maintenance of this build
project will have to be dropped.

The VC++ v7 build is up to date but I will shortly be moving to a new
development platform that will not have VC7 installed. Again, therefore,
we need volunteers who wish to use the VC7 build of GGNFS to volunteer
to maintain it.

The mainline development for VC++ GGNFS builds from my perspective will
in future be on VC8, where I hope to be able to maintain both win32 and
the x64 support.

I intend to use YASM as my assembler as this has support for 64-bit
architectures.

Since this is also NASM compatible the existing NASM based assembler
code source files work with no problems.

I also intend to take a look at FASM, which also has 64-bit support.

Both these assemblers have Windows and Linux versions and this means
that any dedicated assembler code that is written using these assemblers
will be widely available (which is not true if GAS is used).

Please let me know if you have any observations on these issues.

  best regards to all,
