problem compiling pvbrowser with the python binding

Hello pvbrowser community

Pvbrowser compile and works perfectly under my system, but I have not succes making rllib standalone working with python.

I've tried the build_python_interface script with this errors:

compiling pvbrowser gives me the same errors.
my system specifications are a bare Ubuntu 14.04 64 bits

If I try this piece of code:

import sys, os pvslib_path = '/opt/pvb/language_bindings/python/mt' sys.path.insert(0, pvslib_path) import rllib

I get this error:


 File "./main.py", line 48, in

thanks!

"No existe el archivo o el directorio" means "the file or folder doesn't exist"

Answer 2 · 2015-02-10T09:12:46.000Z

Hello
http://swig.org is used for building the language binding from rlllib to
python.
Please install swig and run build_python_interface.sh with the "swig"
commandline parameter.

./build_python_interface.sh swig

(review build.sh and build_python_interface.sh)

PS: We are not very happy with Python a programming language for a
pvserver because Python
has a global thread lock.

Hello

I forgot to mention I had already installed swig
Ok, is insteresting to know this about the pvserver. But I would be ienterested simply to read data from a daemon. (i don't know if the GIL will be a problem in this case) :-/

IN theory I follow the isntructions from the readme file. I don't know what could be wrong

Answer 4 · 2015-02-10T09:30:49.000Z

As far as i have seen you did NOT run swig.
For this you will need the following commandline:

cd pvb/language_bindings
./build_python_interface.sh swig

Alternatively you could run build.sh which builds the Lua binding also:
pvb/language_bindings> cat build.sh
#!/bin/bash
./build_python_interface.sh swig
./build_lua_interface.sh swig

Please send the output when you have still problems.

You got the following message:

g++: fatal error: no input files compilation terminated. make: ***
[qtdatabase.o] Error 4 g++ -c -m64 -pipe -O2 -D_REENTRANT -Wall -W -fPIC
-DQT_NO_DEBUG -DQT_SQL_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_SHARED
-I/usr/share/qt4/mkspecs/linux-g++-64 -I. -I/usr/include/qt4/QtCore
-I/usr/include/qt4/QtGui -I/usr/include/qt4/QtSql -I/usr/include/qt4
-I/usr/include/python2.7 g++:

That is qtdatabase.o is not found.
This code is for binding the qt database library to python.
I suppose you will not need this.

Thus you should comment out qtdatabase from the build process.

Search for qtdatabase:
grep -R qtdatabase python/
python/id/id.pro:HEADERS += ../../sql/qtdatabase.h
python/id/id.pro:SOURCES += ../../sql/qtdatabase.cpp
Übereinstimmungen in Binärdatei python/id/_pv.so.

Übereinstimmungen in Binärdatei python/id/lib_pv.so.1.

and remove qtdatabase from the project files
python/id/id.pro
python/mt/mt.pro

Hi again.

I removed, as you said, qtdatabase.h and qtdatabase.cpp
and the problem with qtdatabase.o compiling is gone.
But I already have the same problem with:
language_binding_rllib_wrap_python.o

I think i'm gonna stick using C or C++ for now, as I see also , as you have commented, some problems within python implementation.
Although if you already want to debug it I can make further changes.

Thanks a lot!

Hi,

I have got a similar case here. My question is how I could actually build this qtdatabase.cpp for the python binding. I executed build.sh on my Ubuntu 14.04 and ran into this issue. Is that normal to have a broken build by default?

Thanks,
Dave

Hello!

Me finally , developed my app using old C++ and not the shiny,quick,marvelous... python :-)
what pvbrowser said about python and gil is true and interesting to read, python works different with threads when take them from C (cpython), etc.

but if you have success I'll try again, and help, of course.

Good luck
