aptos-devel Mailing List for Aptos

Hi Dave, and all, 

Normally I am not able to contribute much, but "What distribution 
do you use?" Is a question I can answer, and if it helps to get 
vapt (or something similar) back in shape, then great. 

As Brent mentioned on 02/22/2016 (I'm paraphrasing here), there is 
an advantage to staying pretty close to the distributions favored 
by the LinuxCNC developers. 

In the past, that was the Long-Term-Support (LTS) versions of Ubuntu, 
great from 6.06 (2006, June), to 8.04 (2008, April), to 10.04 (2010, 
April). When 12.04 came out, Ubuntu (and Gnome) had introduced some 
shenanigans that made users unhappy, including the Unity desktop, 
an Amazon icon, Ubuntu One, Gnome problems, etc., so Ubuntu users 
everywhere (not just LinuxCNC users) began to look around for an 
Ubuntu replacement. Distrowatch at that time showed Ubuntu taking 
a nose dive and Linux Mint coming up fast, so I tried it (for my 
multi-purpose desktops and laptops) and liked it a lot. I've been 
using Mint ever since. 

The LinuxCNC developers (as I recall, anyway) did not release any 
new ISOs in the 12.04 timeframe, but by the time 14.04 came around, 
they had moved to Debian (with XFCE desktop instead of Gnome). And 
that's fine for a CNC machine OS because you have Debian's commitment 
to free/open software in a "minimalist" install, while eliminating 
the problems related to Gnome. So I don't mind using the LinuxCNC 
all-in-one ISO on CNC-machine-only PCs. 

Debian is the parent of Ubuntu, and Ubuntu is the parent of Mint. 
They all use the .deb, apt-get, Synaptic, Aptitude packaging system. 
The problem with the Debian version is that Debian doesn't support 
Ubuntu PPA's (at least not that I know of), so it's a great 
inconvenience not to be able to subscribe to the "daily" builds 
for FreeCad, Kicad, etc. But PPAs work fine on Mint. 

Ubuntu came up with a "Gnome-classic-fallback" mode for 12.04 (and 
14.04) to get rid of Unity and make the start menu look more like 
it did in 10.04, which helped, but may have been too little too late 
for Ubuntu. 

Mint comes in several versions, depending on the desktop. Mint took 
Gnome 3 (ala 12.04) and forked it to become "Cinnamon", and took 
Gnome 2 (ala 10.04) and forked it to become "MATE" (MAH-tay, named 
after the South American tea). Right now it is relatively difficult 
to change from one desktop to another without re-installing, but 
after Ubuntu 16.04 comes out, Mint says that Mint 18 will allow 
users to change from one desktop to another with a couple of 
meta-package clicks in Synaptic. Nice! 

In the interests of full disclosure, Mint does have one 
shenanigan, it comes with mint-search-enhancer preinstalled, 
but it's easy to go into Synaptic and remove it. They say they 
get some funding from that. I wish they wouldn't do it, but, 
it's easy enough to get rid of. 

I'm still running 10.04 on my main desktop, and I need to update. 
So I probably will when Mint 18 (16.04) comes out. I think the 
regular LinuxCNC install script works on Mint, or if not, then 
someone has a LinuxCNC install script for Mint, because I recall 
trying to script-install LinuxCNC as an experiment and it worked. 

Sorry this got kind of long. To summarize: 
For CNC machines I use the LinuxCNC Debian 32 XFCE all-in-one ISO. 
(I have heard rumors that a 64-bit version will be added next time.)
For Desktops/Laptops I use Linux Mint 64 Cinnamon 17.3 (soon 18). 

Hope this helps. 

Kim

Greetings All,

This trip down memory lane to APT360-ville has been most illuminating. I 
am so eager that I purchased an APT training book on Amazon.

The trouble I run into is compiling the apt360 software. So far, I have 
had no luck with SUSE 12.2. Today, I spent 4 hours downloading and 
installing every developmental library/application the software had to 
offer. I still get the error indicating the math library is not found.

I installed UBUNTU 14.04.3 on a spare machine and got apt360 and ppost 
to run. Sadly, vapt is written with libraries that UBUNTU 14.04.3 no 
longer offers.

So, before I flatten another machine, I would like to hear from other 
users the Linux distribution they use.

UBUNTU is okay; but, I did not see any opportunity to select the 
packages prior to loading. SUSE does offer me a list.

With kind regards,

Dave

Hi Dave
The Suse software should work (maybe it's really old, which is maybe why
you are updating, I don't know). The big advantage with Ubuntu is that the
LinuxCNC people use it as their standard system, so there is that. Were you
able to find development packages for Suse?

The windows version is up on the Sourceforge site now. I will cc this to
the list for Phil Fuhlman (jsuber) to see. He has been doing the Windows
stuff. The file is an exec and some ancillary files, so it should just
work, and I think any Windows should be no problem. I could also compile a
static version and send you that, but you might have to do some manual
fiddling to get it to work.

Keep at it, and let me know if more problems come up.
Brent.

You might see if it is a permissions issue. Maybe try to compile as root.
If that works, you can do a make install and be done. It won't solve the
bigger issue of why it isn't compiling, but at least it will get you going.

If it ended up being a permissions issue, and you feel you might want to
compile something in the future, I would look at the /etc/ld.so.conf.d
directory to see if the comments in the ld.so.conf file are fibbing. If so,
maybe you are not a member of a group permission that has ld access or
something. I don't know a great deal about Linux admin, and nothing about
Suse- and they all set up things slightly differently, so I'm just guessing.

I would be interested in knowing about you and your Apt experiences, and am
sure others on the list would too. Let me know your results.
Brent.

Hi David-
The compile is failing during the final step, linking, where all the
individual object files are connected with the libraries on the computer.
The important error messages are the  "cannot find -lm" and "cannot find
-lc" lines. These are the math and C libraries, which should be on every
Linux machine.

There are a couple things that come to mind that might be causing the
problem:

1: You have a 64 bit machine, and it is trying to find 32bit libraries
2. The libraries are in a non-standard place on SuSe

If you are on a 64 bit machine, the current version won't work anyway, but
fear not: I have a 64 bit release ready, I just have to post it to
Sourceforge. You may know already, but ff you run the command:

uname -m

you should find out whether you have a 64bit or 32bit machine. On my 32 bit
machine, I get "i686" and on my 64bit machine I get "x86_64".

To find out where the libraries are, I can run the following command:

find / -name "lib[cm]\.[aso]*" 2>/dev/null

This should tell you where your libraries are, and you can adjust the
configure options (see "./configure --help") to tell it where to find them.
Also look in /etc/ld.so.conf for the places that the gcc compiler is
looking for system libraries.

I don't have time tonight to do anything else, but I should have the 64 bit
version up by this weekend. Let me know what you find out, and we will take
it from there.

Brent-

Greetings,

Having a spot of bother compiling the APT program.

Using SUSE 12.2

With the apt360-1.0.2 source, ./configure seems to have run okay. During 
the "make" portion of the process, I get the following message at the 
end of the file...


/usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: 
Warning: size of symbol `a1stab_' changed from 184 in ACLAS5.o to 192 in 
BLOCK5.o
/usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: 
Warning: alignment 4 of symbol `adfprl_' in ADFPRL.ASM.o is smaller than 
32 in ADFPRE.o
/usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: 
cannot find -lm
/usr/lib/gcc/i586-suse-linux/4.7/../../../../i586-suse-linux/bin/ld: 
cannot find -lc
collect2: error: ld returned 1 exit status
make[2]: *** [apt360] Error 1

make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/david/aptos/apt360-1.0.2'
make: *** [all] Error 2


I am fairly good at following instructions; however, I am not a true 
programmer when it comes to source code.

Anyone offer some hints as to what is missing?

Cheers,

David
