I am looking for a good implementation of C++ with source level debugger for Intel 386/486 based SVR4 implemetations. We have kludged the Glockenspeil SVR3 compiler to work and have AT&T's CFront, but debugging is using sdb (and a real pain). Anyone know of any other possibilities with C++ source level debugging? Dont tell me about SVR3 C++ implementations, most will not work because they mess with the object files to allow linking of static objects, and obviously debuggers need to mess with object files (SVR3 uses COFF format, SVR4 used ELF format).

Isn't everybody? :-) But seriously folks, I (and some other people) are working on some things which may provide people with some nice debugging capabilities for C++ under svr4 in the not too distant future. Unfortunately, I have nothing which I can give you today which works. Later on I hope to be in a position to provide GNU software tools (i.e. C compiler, C++ compiler, and debugger) which work with ELF (that's the easy part) and with "extended" DWARF (i.e. the hard part) to provide a robust debugging environment for C++ on System V Release 4. Many problems have already been solved and much development has already been done, but much work remains. ELF and DWARF support are available now in the GNU C compiler, but the adaptations of the GNU debugger and the GNU G++ compiler still have quite a long way to go. Expect *robust* extended DWARF support in G++ perhaps around Q391 (and perhaps some not-so-robust DWARF support before then. I'd kinda like to see somebody hack cfront to get it to output special #pragmas (which I could then make GCC understand) which would effectively transmit additional crucial C++ level debugging information from cfront through the C compiler, and down into the DWARF information in the object files, but I haven't got either the necessary $20K for a cfront source licence or the necessary time to do that little project.

Okay, I'll bite. What are "ELF" and "DWARF"?

What are "ELF" and "DWARF"? ELF stands for "Extensible Linking Format" (or some such thing). It is the new object file format which is now being used in System V Release 4. DWARF is the debugging information format which is being used within System V Release 4 ELF files by almost everybody who is using V.4 (except Sun). -- // Ron ("Shoot From The Hip") Guilmette // Internet: rfg@ncd.com uucp: ...uunet!lupine!rfg // New motto: If it ain't broke, try using a bigger hammer.
