I can help people build, but I cannot build as I do not have a linux box available to me.

I'm not sure how much older processors we are talking about, but I have Linux Mint on my old Core2Quad (Yorksfield) Q9450.

I tried to get the newest SVN 643. It has gcc/g++ 5.4.0.

There are no configure file and I did not have time to spend checking into this right now, so I just ran "make" but it failed. Any tips would be appreciated, since i'm a Linux "newbie". Full log attached.

Sorry, I never applied the change or committed to SVN. If I remember then I'll do it as soon as I get home.

Ok, I managed to compile it following the guide and it works, so here is a Core2 build:
[URL="http://hoegge.dk/mersenne/pfgw383core2.zip"]pfgw383core2.zip[/URL]

But it says it is using GWNUM 28.6, it is compiled with p95v286.source.zip from the guide.

When I try to use GWNUM from p95v289.source.zip it says:
[QUOTE]GWNUM version mismatch. PFGW is not linked with version 28.6 of GWNUM.[/QUOTE]

You need to put the correct headers into packages/gwnum.

I copied the 7 .h files to packages\gwnum and the gwnum.a to packages\gwnum\64bit. It actually compiles now, but when running it, it still gives the GWNUM version mismatch. I tried with GWNUM from 28.7 source and 28.9 source.

I figured it out and managed to compile it with GWNUM 28.7 and 28.9:

Did you do a "make clean" after moving the header files?

No, that's what I figured out was wrong. Actually I forgot there was a make clean, so I just used a fresh svn download instead.

Apologies for the ignorance.:smile:

I just downloaded the pfgw_win_3.8.3.7z

extracted all files and ran Win64PFGW.exe

An GUI opened up.
I clicked on "Mode" drop-down

Everything is grayed out except for "set PRP base"

How can I use other Modes?

Thank you in advance.
