It is deliberately designed to be extremely simple. As described on the project web site, "The 'S' in 'LADSPA' is meant seriously." The LADSPA development "framework" consists of just one C header file, plus the development tools you will build here. Project Homepage: http://www.ladspa.org Common Build Instructions The build system is not autotools based. However, the makefile is so simple that you will probably want to simply edit and run the makefile manually. Build the package cd src edit makefile INSTALL_PLUGINS_DIR = ... INSTALL_INCLUDE_DIR = ... INSTALL_BINARY_DIR = ... make Install the package make install create multiarch wrappers for all 3 binaries Here is a script that automates this process, while also adding DESTDIR capability, which is missing in the original makefile: cat > build.sh << "EOF" : ${CLFS_LIB32:="lib"} : ${CLFS_LIBN32:="lib32"} : ${CLFS_LIB64:="lib64"} : ${CLFS_LIB:="lib"} eval CLFS_LIB='$'CLFS_LIB${USE_ARCH} && eval BUILD='$'BUILD${USE_ARCH} && eval LD_BUILD='$'LD_BUILD${USE_ARCH} && pushd src && if [ -e makefile-original ]; then make clean mv -f -v makefile-original makefile fi CLFS_LIB=${CLFS_LIB} \ sed -i-original \ -e 's/$(INSTALL_PLUGINS_DIR)/$(DESTDIR)$(INSTALL_PLUGINS_DIR)/g' \ -e 's/$(INSTALL_INCLUDE_DIR)/$(DESTDIR)$(INSTALL_INCLUDE_DIR)/g' \ -e 's/$(INSTALL_BINARY_DIR)/$(DESTDIR)$(INSTALL_BINARY_DIR)/g' \ -e "s|/usr/local|/usr|g" \ -e "s|/lib/|/${CLFS_LIB}/|g" \ makefile && make \ DESTDIR=${DESTDIR} \ CC="gcc ${BUILD}" \ CPP="g++ ${BUILD}" \ LD="ld ${LD_BUILD}" && make install && if [ "$USE_ARCH" != "" ]; then mv -v ${DESTDIR}/usr/bin/analyseplugin ${DESTDIR}/usr/bin/analyseplugin-${USE_ARCH} && mv -v ${DESTDIR}/usr/bin/applyplugin ${DESTDIR}/usr/bin/applyplugin-${USE_ARCH} && mv -v ${DESTDIR}/usr/bin/listplugins ${DESTDIR}/usr/bin/listplugins-${USE_ARCH} fi if [ "${USE_ARCH}" == "64" ]; then ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/analyseplugin && ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/applyplugin && ln -sfv multiarch_wrapper ${DESTDIR}/usr/bin/listplugins fi popd EOF chmod +x build.sh Non-Multilib Compile and install the package: ./build.sh Multilib 32Bit Compile and install the package: USE_ARCH=32 ./build.sh N32 Compile and install the package: To Do: (Please Contribute. It is intended that "USE_ARCH=N32 ./build.sh" should work.) 64Bit Compile and install the package: USE_ARCH=64 ./build.sh Configuring An environment variable, LADSPA_PATH, is required. cat > /etc/profile.d/50-ladspa.sh << "EOF" export LADSPA_PATH=/usr/lib/ladspa:/usr/lib32/ladspa:/usr/lib64/ladspa EOF Contents Installed Directories: /usr/lib{,32,64}/ladspa Installed Programs: analyseplugin, applyplugin, listplugins Installed Libraries: amp.so, delay.so, filter.so, noise.so, sine.so Short Descriptions analyseplugin, applyplugin, listplugins are tools for inspecting and testing ladspa plug-ins. amp.so, delay.so, filter.so, noise.so, sine.so are sample plug-ins /usr/include/ladspa.h is the API, in its entirety. The comments in this (well-commented) header file comprise the API documentation. [[Category:<Programming>]]
