[Solved] Compiling errors when making (with the latest kaldi toolkit)

[CyanHillFox]

--Updated 11/29/2017 The problem is solved by using older kaldi toolkit (the version committed on 9/9/2017).

--Original First sorry for my poor English. I'm trying to install kaldi-python, but I received compiling errors(see below) when making. I don't know whether it is because I'm using the wrong boost library, which I installed with sudo apt-get libboost-dev-all. And the GCC version I'm using is 5.4.0(on Ubuntu 16.04).

Sincerely.

The errors are like:

Hi Elecky, I encounter the same error. How did you solve this problem?

[CyanHillFox]

@junjunmin The problem is solved by using older kaldi toolkit (the version committed on 9/9/2017), you can give it a try.

FYI it looks like the cause of the error is this line changing in kaldi-table.h: const T &Value(); to T &Value(); which now doesn't match with const T &Value() const {return t_;} in kaldi_io_internal.cpp.

I encountered this recently. Can this be solved by modifying the source code in 'kaldi_io_internal.cpp'? @jfainberg

[jfainberg]

@zhange1990 Possibly, yes. I'm sorry I don't remember if I tried or what the outcome was...

I encountered this recently. Is it required to set the boost lib to a specific version? @Elecky @janchorowski

I have encountered this problem.. Tried with older version of kaldi(5.2) but still facing the error.. error: no match for call to ‘(const boost::python::detail::copy_const_reference_expects_a_const_reference_return_type<boost::python::api::object&>) (boost::python::api::object&)’
