I'm just trying to compile the git master. It fails: project_build/core/seq_cv.o: In function `SEQ_CV_IfSet': D:\Temp\midibox_seq_v4/core/seq_cv.c:154: undefined reference to `AOUT_IF_MaxChannelsGet' collect2.exe: error: ld returned 1 exit status make: *** [project_build/project.elf] Error 1 Did I miss something? I'm compiling for LPC1769 / Midibox v4. EDIT: Sorry, I forgot to switch to the new MIOS32_PATH for my environment variable. Everything is fine. Best regards, rio
