Hey Joseph,

I fixed the issues in this commit: http://dev.monetdb.org/hg/MonetDB/rev/c6652f31100a

Compiling with Python 3 UDFs should work now.

Regards,

Mark

Hi all,

Has anyone had any luck building the sources with Python 3 ?

I tried building the Dec2016 branch from git, passing 

--with-python3=/usr/bin/python3 --with-pyversion=/usr/bin/python3 --with-pyconfig=/usr/bin/python3-config

to configure, but received many errors during make under the pyapi directory, such as.

/usr/include/python3.5m/object.h:86:5: error: missing braces around initializer [-Werror=missing-braces]

     { _PyObject_EXTRA_INIT              \

     ^

connection.c:159:5: note: in expansion of macro ‘PyObject_HEAD_INIT’

     PyObject_HEAD_INIT(NULL)

     ^

/usr/include/python3.5m/object.h:86:5: note: (near initialization for ‘Py_ConnectionType.ob_base’)

     { _PyObject_EXTRA_INIT              \

     ^

connection.c:159:5: note: in expansion of macro ‘PyObject_HEAD_INIT’

     PyObject_HEAD_INIT(NULL)

     ^

connection.c:159:5: error: missing initializer for field ‘ob_size’ of ‘PyVarObject {aka struct <anonymous>}’ [-Werror=missing-field-initializers]

.................

connection.c:246:5: error: ‘return’ with a value, in function returning void [-Werror]

     import_array();

     ^

It looks like some of the macro definitions to make python3 header files work with the pyapi source might be missing. I tried fixing some of the sources like unicode.c, formatinput.c etc. But it looks like majority of the source files have issues.

Thanks,

Joseph
