Re: [pypy-dev] Tkinter ?

2017-09-30 Thread Stuart Axon via pypy-dev 
Here is backend_wx.pyhttps://pastebin.com/0bHs4rY5
from~/.virtualenvs/pypy-nightly-trunk/site-packages/matplotlib-2.1.0rc1+112.g17ec41612.dirty-py2.7-linux-x86_64.egg/matplotlib/backends/backend_wx.py
 


Around line 1818 there is a mix of tabs and spaces, which doesn't seem right.
Also  "class PrintoutWx(wx.Printout):" appears more than once.



I'm using the method from that webpage, the only change is I added "sudo" and 
"-y" to the apt-get line.
I used my script to grab pypy 
nightly:https://gist.github.com/stuaxo/5d4c0363317a875617271a6d424abbba
activated the virtualenv it created for trunk
$ source ~/.virtualenvs/pypy-nightly-trunk/bin/activate

Then ran the script - pointing at the virtualenv$ ./build_wx-cffi.sh 
$VIRTUAL_ENV

I noticed this error when building:

None of the GUI backends currently work out of the box with PyPy, see for

Might also be worth checking out

The none-gui backends should work, ie ipython inline or Jupyter notebooks.

 Hi Amaury,

 In fd331e4bf733 you did an untested change to the tkinter library; as
 it turns out, the CPython tests find problems:

 Can you fix the situation?  Thanks!


Actually my changes were trying to fix the test failures in this test_tcl
file, since the merge of stdlib-2.7.10.
This Tcl_NewWideIntObj function is used probably only in the 32bit case.

Should be fixed with 6453697f3a30.

Re: [pypy-dev] Tkinter-pypy not building on windows

2012-01-18 Thread Arnaud F 
Still no luck.
I made sure that i am using the correct version of tcl/tk and tested the
compilation of tkinter with python27 and it worked.
With pypy, i still have to define WITH_THREAD (it's defined in pyconfig.h
for python27 but not in pypy-1.7); I also had to modify the setup.py since
i used tcl/tk 8.5 (and the libs do not have the dot in windows : tcl85 and
tk85)
Now I get missing libs error from the linker :

LINK : fatal error LNK1181: cannot open input file 'X11.lib'
LINK : fatal error LNK1181: cannot open input file 'python27.lib'

if i try to remove X11 from the librairies in setup.py and add a path to
python27.lib, i get a lot of unresolved external symbols

Thanks

 Hi,

 2012/1/17 Arnaud F pachalm...@gmail.com

 When trying to build tkinter from source, i get the following errors :

   [...]

 src/_tkinter.c(3133) : error C2065: 'tcl_lock' : undeclared identifier


 Which version of tcl are you using? Are you sure it was compiled with
 threads?
 There is a comment about this at the beginning of _tkinter.c:
 /* If Tcl is compiled for threads, we must also define TCL_THREAD. We
 define
it always; if Tcl is not threaded, the thread functions in
Tcl are empty.  */
 But compilation with a thread-less TCL is probably not so well supported.

How comes that you need the X11 library? didn't you build a dll version of
tcl/tk? (tcl85.dll, tk85.dll)
Don't use the CPython python27.lib, you should use the one shipped with
pypy; it's possible that it is named libpypy.lib instead. Just rename it if
needed.

2012-01-18 Thread Arnaud F 
The reference to X11.lib comes from the original setup.py. The reference to
python27.lib seems to come from distutils (build_ext.py, in the
get_libraries method)
I didn't find any .lib file in my pypy installation (the standard binaries
version 1.7 32bits for windows), just some dlls.
Do I need to rebuild pypy from source ?

There is a comment about this at the beginning of _tkinter.c:
/* If Tcl is compiled for threads, we must also define TCL_THREAD. We define
   it always; if Tcl is not threaded, the thread functions in
   Tcl are empty.  */
But compilation with a thread-less TCL is probably not so well supported.
