the problem here comes from the fact that you have some: (u32 *)&foo with foo beeing a float passed to functions. that's super ugly. you can expand the code by doing this (this remains super ugly, I'm even not sure it's not endian-dependant): double *dblp = &foo; function_call((u32 *)dblp) ... that patch will work for each part of HCRope.cpp. another super ugly possiiblity is to add -Wno-strict-aliasing to CFLAGS. -- ·O· Pierre Habouzit ··O [EMAIL PROTECTED] OOO http://www.madism.org
