Thanks, I changed the entries in the pybind11 portfile as well as in the
OpenImageIO portfile to point to Python 2.7. and it compiles without
complaints.
But importing the final module into python fails (python crashes):
>>> import OpenImageIO as oii
Fatal Python error: PyThreadState_Get: no current thread
Vcpkg uses its own python2.7 libs which are for python 2.7.15 whereas
the installed python interpreter is version 2.7.14. Any idea what I can try?

You can build Python2.7 bindings with OIIO. I don't know why they
changed to Python3, but in \vcpkg-master\ports\pybind11\portfile.make
you can replace Python3 with Python2.

Hi,
I tried to compile the current OIIO 2.2.3 myself. The reason why I
not
use vcpkg is that I need the python2.7 bindings, with vcpkg I was
unable
to build a working 2.7 python library.
So I decieded to try it myself. I use cmake-gui and try to build a
static version of the OIIO libs. My plan is to use only the required
libs to builds to build oiio and if everything works I would try to
include more plugins step by step. I was able to build the
OpenImageIO
libs and almost all the tools. Only the oiiotool refuses to
compile with
this error:
Error C2664 'OpenImageIO_v2_2::ArgParse::Arg
&OpenImageIO_v2_2::ArgParse::Arg::action(int (__cdecl *)(int,const
char
**))': cannot convert argument 1 from 'void (__cdecl
*)(OpenImageIO_v2_2::span<const char *const ,-1>)' to
'OpenImageIO_v2_2::ArgParse::ArgAction &&' oiiotool
D:\UserDatenHaggi\Documents\coding\oiio\src\oiiotool\oiiotool.cpp 5652
The line in the oiiotool.cpp is this one:
ap.arg("--info")
.help("Print resolution and basic info on all inputs, detailed
metadata if -v is also used (options: format=xml:verbose=1)")
.action(set_printinfo);
Then I tried to compile the oiio python plugin with pybind11-2.5.0
and
get this errormessage:
d:\userdatenhaggi\documents\coding\oiio\src\python\py_oiio.h(270):
error
C2662: 'pybind11::buffer_info pybind11::buffer::request(bool)':
cannot
convert 'this' pointer from 'const pybind11::buffer' to
'pybind11::buffer &'
What is this line:
template<typename T>
inline bool
py_buffer_to_stdvector(std::vector<T>& vals, const py::buffer& obj)
{
OIIO_DASSERT(py::isinstance<py::buffer>(obj));
270>> oiio_bufinfo binfo(obj.request());
bool ok = true;
I'd really appreciate if anyone could give me a hint what I can do to
solve these problems.
Thanks a lot.
