compilation in ubuntu 17.04

[cristianofigo]

trying to compile with portaudio suport:

livre@livre:~/Documentos/opensmile-2.3.0$ ./buildWithPortAudio.sh

everything fine until:

Newer gcc Version does not tolerate cast from char to unsigned char, thus you need to change the casts of the consts from char to unsigned char in vectorTransform.hpp in line 117. It will be solved in version 2.4. which will be released by audEERING soon.

... for larger values of soon. But changing (char)0xEE to (unsigned char)0xEE is enough to get over this one

Also got stuck here. Doesn't seem like such a difficult issue to patch.

I also encountered with that issue. If you are too 'lazy' to change it manually, you can type the following command on the terminal when you are in opensmile-2.3.0: sed -i '117s/(char)/(unsigned char)/g' src/include/core/vectorTransform.hpp

If you are on the same level with opensmile-2.3.0 directory, you can type: sed -i '117s/(char)/(unsigned char)/g' opensmile-2.3.0/src/include/core/vectorTransform.hpp
