Hi all, I'm currently modifying the avw.lv2 plugins to use the new extension from lv2: time. To do so, I'm switching from the old lv2-c++-tools to the new lvtk http://lvtoolkit.org. I haven't started to use the new extension just yet, I'm simply migrating my code to this new toolkit. Most of the code compile well, except the UI classes. I'm getting this type of error: [117/134] cxx: src/vco2_gui.cpp -> build/src/vco2_gui.cpp.63.o [118/134] cxxshlib: build/src/vco2_gui.cpp.63.o -> build/avw.lv2/vco2_gui.so /usr/bin/ld: cannot find nodelete: No such file or directory collect2: error: ld returned 1 exit status Waf: Leaving directory `/home/blablack/src/avw.lv2/build' Build failed -> task in 'vco2_gui' failed (exit status 1): {task 13619920: cxxshlib vco2_gui.cpp.63.o -> vco2_gui.so} ['/usr/bin/g++', '-shared', '-pthread', '-Wl,nodelete', 'src/vco2_gui.cpp.63.o', '-o', '/home/blablack/src/avw.lv2/build/avw.lv2/vco2_gui.so', '-Wl,-Bstatic', '-Wl,-Bdynamic', '-llvtk_plugin1', '-llvtk_ui1', '-lgtkmm-2.4', '-latkmm-1.6', '-lgdkmm-2.4', '-lgiomm-2.4', '-lpangomm-1.4', '-lgtk-x11-2.0', '-lglibmm-2.4', '-lcairomm-1.0', '-lsigc-2.0', '-lgdk-x11-2.0', '-latk-1.0', '-lgio-2.0', '-lpangoft2-1.0', '-lpangocairo-1.0', '-lgdk_pixbuf-2.0', '-lcairo', '-lpango-1.0', '-lfreetype', '-lfontconfig', '-lgobject-2.0', '-lglib-2.0'] I simply don't understand the error, it looks like ld is using nodelete as a filename instead of an argument. The build system I'm using is waf, and I modified the wscript to use c++11 (which seems to be required by lvtk, and I have no idea if this is related or not). I admit that I'm completely out of my depth here, so I commited the code onto my svn: svn checkout svn://svn.code.sf.net/p/avwlv2/code/trunk avwlv2-code Thanks in advance for any help! Aurélien
