Hi => Niklas! interesting... try this: change line 49 to: #define push_uint( sp, val ) *((uint*&)sp) = val; ((uint*&)sp)++ Does this fix it? Best, Ge! On Sunday, July 11, 2004, at 11:10 PM, Niklas Werner wrote:

yes. BUT: gcc -D__LINUX_ALSA__ -O3 -g -c ugen_osc.cpp ugen_osc.cpp: In function `void sinosc_cget_freq(double, void*, void*)': ugen_osc.cpp:179: error: ISO C++ forbids cast to non-reference type used as lvalue and several more related to the set of macros SET_NEXT_*() and GET_NEXT_*() changing all of them accordingly to: #define SET_NEXT_FLOAT(ptr,v) (*((t_CKFLOAT *&)ptr)++=v) etc. makes chuck compile and run with gcc-3.4.1 (I just quickly ran the examples, not sure whether this breaks anything else.)

This is an interesting error. We can't treat the sp and pointer variables as lvalues to do assignments when we cast to non-reference pointers. This makes sense, it is interesting that gcc just now decided to care. Thanks Niklas. Best, Ge! On Jul 12, 2004, at 12:07 AM, Niklas Werner wrote:
