Stop. mv: cannot stat 'Makefile': No such file or directory ------ The start of blds/bld_prepare.sh say #!/bin/bash # need lv2 plugins (eg. lv2-calf-plugin) lv2-dev is included in only two package lists, for Ubuntu and Debian!? I add-installed lv2-devel, next also liblilv-0-devel and lv2-calf on Slowroll, but still bld.sh claims "configure: error: lv2 requested but no lv2 headers found" So I'm stuck here (again). ---- Try to verify if lv2.h are installed: find /usr/include -name lv2.h /usr/include/lv2.h /usr/include/lv2/lv2.h /usr/include/lv2/core/lv2.h /usr/include/lv2/lv2plug.in/ns/lv2core/lv2.h pkg-config --cflags lv2 pkg-config --cflags lv2.h Package lv2.h was not found in the pkg-config search path. Perhaps you should add the directory containing `lv2.h.pc' to the PKG_CONFIG_PATH environment variable Package 'lv2.h' not found
