I suspect this question has been asked a million times before, but I've never read this group... anyway, is there anything special I need to do to compile the NIH class library with g++? I've got version 2.204a of the NIH class library, 1.37.0 g++, a Sun Sparc 1 (4/60), and SunOS 4.0.3c. Please respond via email to the address below. Thanks! ------------------------------------------------------------------------ |Eric Hanchrow nosun.west.sun.com!yamada-sun!eric | |Phase III Logic, Inc. cse.ogi.edu!yamada-sun!eric | |1600 N.W. 167th Place Beaverton, OR 97006-4800 USA | |Voice: (503)-645-0313 Fax: (503)-645-0207 as of 4-Oct-89| --------------Crackling-noises-OK--do-not-correct!----------------------

Does anyone know what is "fd_set" used in FDSet.h of NIHCL? Is it a struct or a class? Which header supposes to declare it? I am trying to port this library but both AT&T 2.1 C++ and g++ header files do not have this struct/class/or whatever it is.

When using the select(2) system call a bit string is returned when a file descriptor can support I/O with out blocking. The structure defined for this bit string is called fd_set. It is defined in /usr/include/sys/types.h See the man page on select(2) Evan R.

Thanks everyone for helping with the fd_set structure problem. I found out that we have it in our system in /usr/include/sys/select.h. I need to define _BSD in order to get to this structure. However, I just found a new problem and wonder if you could help me: The class FDSet was defined as class FDSet: public VIRTUAL Object { .... private: fd_set fs; protected: virtual void storer(OIOofd&) const; virtual void storer(OIOout&) const; .... }; where fd_set is typedef struct fd_set { fd_mask fds_bits[howmany(FD_SETSIZE, NFDBITS)]; } fd_set; And in FDSet.c we have the following: void FDSet::storer(OIOofd& fd) const { BASE::storer(fd); fd.put((const char*)&fs,(unsigned)sizeof(fs)); } Which AT&T C++ compiler on my system complaints that you could not take address of member FDSet::fs of const struct FDSet Did anyone run into this problem when they were trying to build it? Or my NIHCL is out of date.
