Title: Sample videofilter Demo does not compile. New Error 'undefined reference'
Post by: olir on June 05, 2017, 04:49:01 PM
I got an error when compiling sample videofilter under windows that is not handle under "Important/Common problem".

Fresh installed Software today: avidemux_2.6.21_win64.exe, msys2-x86_64-20161025.exe, mingw-w64-install.exe, cmake-3.8.2-win64-x64.msi
cmake worked fine.

CLI output of mingw32-make:

try adding
ADD_DEFINITIONS("-std=c++11")

at the top of the makefile

Did not work. cleared build, run cmake, edited, and run make.

the opposite then
ADD_DEFINITIONS("-std=c++98")

or

ADD_DEFINITIONS("-std=g++98")

ADD_DEFINITIONS("-std=c++98")  had no effect

ADD_DEFINITIONS("-std=g++98") raised the error:   g++.exe: error: unrecognized command line option '-std=g++98'

Which library is the symbol in? Does it maybe need to be linked directly?
Title: Re: Sample videofilter Demo does not compile. New Error 'undefined reference'
Post by: mean on June 05, 2017, 07:38:49 PM
The problem is the lib export foobar
and the object you compiled requires
foobar_cx11

The simplest is to use mxe
It takes a bit of time to compile but it works well
and you have everything compiled with the same compiler which is crucial on windows
