Linux compilation

[bizaro]

Hello,

On my system I have :
python 2.7.12 & QT5.7

python.prf is : 2.7.

during the building of PythonQt I obtain :

PythonQt.cpp:1932:42: fatal error: private/qmetaobjectbuilder_p.h: Aucun fichier ou dossier de ce type
#include <private qmetaobjectbuilder_p.h="">
^
compilation terminated.
Makefile:368 : la recette pour la cible « PythonQt.o » a échouée
make[1]: [PythonQt.o] Erreur 1
make[1] : on quitte le répertoire « /usr/local/PythonQt3.1/src »
Makefile:79 : la recette pour la cible « sub-src-make_default-ordered » a échouée
make: [sub-src-make_default-ordered] Erreur 2

What I'm doing wrong?

You are missing core-private, the private headers for QtCore.
Maybe you did not compile/install Qt completely?

Hello,

For certain features (such as the built-in help() function), Python checks whether it’s a tty. When you’re making an embedded console in PythonQt, this didn’t work. The patch below adds this to stdin.

Kind regards,
Sander Stoks

Hi,
I don't have the qmetaobjectbuilder_p.h, so I add the sources with the qt maintenance tool. because you tell me about the private headers for QtCore. thank you :)

The make build the libPythonQt.so and libPythonQt_QtAll.so and stop again.

don't find :
PyUnicodeUCS2_decodeUTF16 and PyUnicodeUCS2_AsUTF8String :(

thank you for your help .

Hi,

For future readers: if you were using apt-get to install Qt in your system, you can get this header by doing

sudo apt-get install qtbase5-private-dev

Regards,
Sander

Ok i will try that..

thanks you

[bizaro]

Both windows or linux make have a problem with PythonQTdecorators...

[bizaro]

Thank you for your answer.

I change the original PythonQtStdln.cpp for that :

#include "PythonQtStdIn.h"

static PyObject *PythonQtStdInRedirect_new(PyTypeObject *type, PyObject * /*args*/, PyObject * /*kwds*/)
{
  PythonQtStdInRedirect *self;
  self = (PythonQtStdInRedirect *)type->tp_alloc(type, 0);
  self->_cb = NULL;
  self->_callData = NULL;

  return (PyObject *)self;
}

static PyObject *PythonQtStdInRedirect_readline(PyObject * self, PyObject * args)
{
  PythonQtStdInRedirect*  s = (PythonQtStdInRedirect*)self;
  QString string;
  if (s->_cb) {
    string =  (*s->_cb)(s->_callData);
    }
  return Py_BuildValue("s", string.toLatin1().constData());
}

static PyObject PythonQtStdInRedirect_isatty(PyObject * self)
{
 Py_RETURN_TRUE;
}

static PyMethodDef PythonQtStdInRedirect_methods[] = {
  {"readline", (PyCFunction)PythonQtStdInRedirect_readline, METH_VARARGS,
   "read input line"},
 {"isatty", (PyCFunction)PythonQtStdInRedirect_isatty, METH_NOARGS,
 "is this a tty"},
 {NULL, NULL, 0 , NULL} 
};

static PyMemberDef PythonQtStdInRedirect_members[] = {
  {NULL}  
};

PyTypeObject PythonQtStdInRedirectType = {
    PyVarObject_HEAD_INIT(NULL, 0)

during the make step I obtain this error :

Hello,

My apologies - my patch was for an unrelated issue, not related to Linux compilation. I thought I was posting a new topic.
