Build fail on Arch

[looplog]

Attempting to build on Arch(x86) fails for me at the linuxsampler plugin:

I should add that I am running a patched version of linuxsampler-svn to reduce the channel count of the LV2 plugin to stereo. Is this the likely cause of this failure?

This is a bug in linuxsampler code, please report a bug to them.

For now you can edit your local "/usr/include/linuxsampler/common/global.h" and change:
#if IS_CPP11
to:
#ifdef IS_CPP11

Indeed that fixes the issue. Thanks
