Unfortunately, the official toolchain for cross-compiling for Pi is, as of yet, using an old ''gcc'' version (4.3.9) and hence, the configure script may fail to detect the ''FluidSynth'' library specifically. FluidSynth and MT-32 emulation are features that are very demanding on CPU processing power so it should be ok to skip them entirely. Alternatively, you could seek out a more up-to-date ''armhf'' toolchain for the cross-compilation, such as this [https://github.com/Pro/raspi-toolchain/releases Raspberry Pi toolchain by Stefan Profanter (Pro)] which, in its 1.0.1 version, uses ''gcc'' version 8.3.0. | Unfortunately, the official toolchain for cross-compiling for Pi is, as of yet, using an old ''gcc'' version (4.3.9) and hence, the configure script may fail to detect the ''FluidSynth'' library specifically.

Specifically, this toolchain needs to be installed in ''/opt/cross-pi-gcc'' since it's not location independent. | ||
