Your delete() probably doesn't throw any exceptions so gxx sees that at a bad declaration. I fixed it by using -fno-exceptions and -fno-rtti but I'm guessing from your makefile that you do want exceptions. Hopefully someone knows the new way to define delete() for a custom delete() function. > c:/djgpp/lang/cxx/stl_algo.h:617: `lrand48' undeclared (first use this = > function) Sorry, can't help with this one. - Tel > ------=_NextPart_000_0037_01BD6256.5948E1A0 > Content-Type: text/html; > charset="iso-8859-1" > Content-Transfer-Encoding: quoted-printable > > > > http-equiv=3DContent-Type> > > > >
