BelaCsound.cpp: setup(), render(), an cleanup() functions 7to be used in Bela C++ projects, requiring linking to the Csound library 8 92. belacsound: a standalone executable, built from CMake with 10-DBUILD_BELA=1 11 12Build instructions 13========================================= 14 15To build Csound on the board (as root), just do, from the 16top-level sources 17 18``` 19$ cp Bela/Custom.cmake.bela Custom.cmake 20$ mkdir build && cd build 21$ cmake .. -DBUILD_BELA=1 -DUSE_DOUBLE=0 -DCMAKE_BUILD_TYPE=Release 22$ make && make install 23$ sudo ldconfig 24``` 25 26Csound is installed by default in /usr/local. Other locations can be 27selected by setting the CMake variable CMAKE_INSTALL_PREFIX. 28 29Cross-compiling instructions 30========================================= 31 32A file crosscompile-setup.sh is provided to either build the pre-requisites 33(xenomai and Bela libs) or at least guide you through what is needed. 34 351. Setup your cross-compiling toolchain for armhf. On Debian stretch 36this means apt-get install arm-linux-gnueabihf-g++ cross-compile-essential-arm 37libsndfile1-dev:armhf libasound-dev:armhf and possibly other things. 38 392. Build and install xenomai for armhf. 40 413. Build libbela and libbelaextra for armhf. 42 434. Build libNE10 for armhf and replace the one in Bela/lib/libNE10.a. 44 455. Build Csound for armhf 46 47``` 48$ cmake -DCMAKE_TOOLCHAIN_FILE=../Bela/crosscompile.cmake \ 49 -DUSE_DOUBLE=0 -DBUILD_BELA=1 -DCMAKE_BUILD_TYPE=Release .. 50$ make 51$ make install 52``` 53 54The belacsound program should appear in your binary install directory. Read access 55to /root/Bela/lib and /root/Bela/include is needed even if these directories are 56empty. 57 58 59 60 61 62 63 64 65 66
