Re: [Emc-developers] Error during make

2016-01-06 Thread Niemand Sonst 
OK, I see and understand that there more important stuff to do.
So see this as closed.

So I will make all my further development only in 2.7 and ask someone 
else to merge it to master.

As machinekit is working fine on my laptop with RT Kernel, I will just 
wait till linuxcnc also offers a kernel for Jessie.

I did verify that, unlike last time, std::end is missing on the Ubuntu
10.04 machine I have access to (so it's not simply a missing header
again):

$ cat std_end.cc
#include 
const char c[]{1,2,3,4};
auto p = std::end(c);

[on ubuntu 10.04]
$ g++ -std=c++0x std_end.cc && echo success
std_end.cc:3: error: ‘end’ is not a member of ‘std’
std_end.cc:3: error: unable to deduce ‘auto’ from ‘’

[on debian wheezy]
$ g++ -c -std=c++11 std_end.cc && echo success
success

Use of std::end was introduced at commit e38ff45f16 to fix real (if
minor) technical debt; because the new code is type safe, if the
underlying type of the members missing, optional and so forth change so
that they cannot be initialized by the literal constant 0, it will be a
compiler error.  Before my change, the type of these members did not
matter; they would be initialized to all-bits-zero which is undefined
behavior if they are later changed to some C++ types that are not "plain
old data".

At this point I choose not to make any further efforts to fix master
branch support for Ubuntu 10.04.  If someone else produces patches to do
this, I will do my best to evaluate them impartially, but as I have
explained I view the change as important and would not like to see it
simply reverted.

I have done that within the python 2.7 environment and with rip-environment
So I do not understand why I get the error during make with master, but 
not with 2.7

Re: [Emc-developers] Error during make

2016-01-03 Thread EBo 
My guess is that the environment is different between when it is 
compiling and at your desktop, and may be a pain to find.  Try 
copy/pasting the line that is failing during the build and see if that 
will work.  I doubt that it is "g++-4.4 -std=c++0x -c nbi.cc && echo 
success".  This will let you know if there another problem (like 
std=c++0x not being set, or possibly the error being on a different line 
of code).

Just a thought.

OK.  But when you are compiling whatever code has the nearbyint in it, 
what is the full command line to compile that?  Can you copy/paste the 
exact error?  You may have done it before, but I have deleted all the 
email chain.

isn't included in rs274ngc_interp.hh.

I just pushed this change to master branch which may fix it:

[Emc-developers] Error during make

2016-01-02 Thread Niemand Sonst 
Hallo,

this could be an error due to my config!

I installed python 2.7 under Ubuntu 10.04, this way and do run it in a 
virtualenv:

--

# getting python 2.7 on Ubuntu 10.04
# add the repository to sources-list
deb http://ppa.launchpad.net/fkrull/deadsnakes/ubuntu lucid main

sudo apt-get install python2.7 python2.7-dev

# get the setuptools neded for virtual environment
wget https://bitbucket.org/pypa/setuptools/raw/0.8/ez_setup.py

# install it in the user dir

# change to that dir, it might not be in path
cd .local/bin

# install the new pip version using python 2.7
./easy_install-2.7 pip

# install the virtualenv
sudo ./pip2.7 install virtualenv

# change back to home dit
cd

# make a dir to save the environments

# change to that dir

# actiavte the environment and see that the cursor changed
source bin/activate

# type python --version and see if that is now 2.7

# to leave the environment just type
deactivate

# and to go back in:
cd .virtualenv
source bin/activate
--

I the changed in the same terminal to my linuxcnc source directory 
(branch master) and did
cd src
make clean
./autogen.sh
./configure

No error or warning till here!!!

I type make and get an strange error:

..

.

IMO nearbyint is a member of std.

See what gives python --version
...
(.virtualenv)emcmesa@emc-mesa:~/linuxcnc-org/src$ python --version
Python 2.7.6
(.virtualenv)emcmesa@emc-mesa:~/linuxcnc-org/src$


I could not see the error related to python, but why does the error pop up?

I just changed the branch from master to 2.7 and in that case make went 
through without mistake!
I am not jet able to run any GUI, because I miss some side pakates, but 
I can not see the differnce in make between 2.7 and master.

g++-4.4?  I thought C++11 support was not added until much later (like 
4.7+).

https://gcc.gnu.org/projects/cxx0x.html

What is the compiler and stl versions on both machines?

Yes, std::nearbyint is specified in C++11, at least according to 
http://en.cppreference.com/w/cpp/numeric/math/nearbyint

On the one Ubuntu 10.04 system I have easy access to, I can't install
the build dependencies of linuxcnc, but this translation unit does
compile with "g++-4.4 -std=c++0x" or "g++-4.4 -std=gnu++0x":

#include 
const auto i = std::nearbyint(3.14);

so either it's some local detail of your system or some additional
compiler flag that LinuxCNC has added.  You can see full compiler
commandlines if you run make V=1

The call was added to LinuxCNC recently in the master branch after we
dropped support for 10.04, and so it was never tested on 10.04.
