Does anybody know if FreeCAD v.17 can run in a AMD K7 (without SSE2) from early 2000?
I installed freecad-daily and I get illegal instruction...

Re: FreeCAD in a very old machine
Hi Abdullah, I do not know the answer but I think it is also important to tell what your installed OS is

Yes, definitely. I can install in the computer whatever linux distribution. The priority is that it runs FC. Currently it is running Lubuntu 17.04.
I have debug my run, and apparently one of the dependencies, xerces-c, is compiled with sse2 support by default in that version of lubuntu. I am building it from source to disable sse2 now...

Out of curiosity, how is this controlled? Compiler optimization flags?abdullah wrote:I have debug my run, and apparently one of the dependencies, xerces-c, is compiled with sse2 support by default in that version of lubuntu. I am building it from source to disable sse2 now...
"fight the good fight"
Re: FreeCAD in a very old machine
for this case, there is a --disable-sse2 configuration flag that you add to your debian/rules.sgrogan wrote:Out of curiosity, how is this controlled?

Re: FreeCAD in a very old machine
I am going to cry out of joy... it works!! I am running FreeCAD v.17 in a 15+ old computer running lubuntu 17.04 and I must say it does not lag!!sgrogan wrote:Out of curiosity, how is this controlled? Compiler optimization flags?
If anybody needs to run FC in a pre K8 AMD processor without SSE2, just install xerces-c from source. Before executing debuild, in the source directory, just edit debian/rules and in the "override_dh_auto_configure: dh_auto_configure" section add --disable-sse2 at the end. Save, execute debuild and then install the packages. Done!

interesting!
I have found in the past that the GPU in old machines can be a problem in that some OpenGL features are not supported and then you find the occasional odd bug like constraint values not showing up in sketcher. I once had a laptop with a very old GPU and despite Werner changing some stuff, the problem never was fixed for me, but that was a very old Pentium 3 laptop which I have since chucked out.
Re: FreeCAD in a very old machine
In this machine I see the constraints in blue (I mean the driving constraints). Otherwise it works reasonably well. My neighbour's son is very happy with it so far
