If you can repeat it, compile with another Extended Pascal compiler, for example Prospero's one. If that fails too, there is really something wrong with the code. But I suspect gpc.

I used curspriv.h in some GPC versions, but not in the current one, so I didn't notice the problem when I uploaded pdcurs24. So, in order to use pdcurs24 you have two choices: - Get the most recent GPC alpha (though I'm not sure if there are DJGPP binaries available), or - get curspriv.h from the PDCurses sources (ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/libs/pdcurs24.beta.22-May-99.zip) > What we have to do?

The pipe/fork problem occurred under mingw, in this case the problems reported were: : /usr/local/lib/gcc-lib/i586-pc-linux-gnu/2.95.2/units/pipec.o: In function : `_p_pipe': : /usr/local/lib/gcc-lib/i586-pc-linux-gnu/2.95.2/units/pipec.o(.text+0x0): : multiple definition of `_p_pipe' : pipec.o:/usr/local/src/gcc-2.95.2/gcc/p/test/./../units/pipec.c:40: first : defined here : /usr/bin/ld: Warning: size of symbol `_p_pipe' changed from 490 to 599 in : /usr/local/lib/gcc-lib/i586-pc-linux-gnu/2.95.2/units/pipec.o Which means that GPC does not always recognize differently written identical file names...

I can see I need to read gpc.pas more carefully to see what other nice features are in there. -- David James mailto:david@tcs01.demon.co.uk Special Stage Rally results archive <URL:http://www.tcs01.demon.co.uk/>

Not really. Generally, we expect all tests in that directory to succeed. But I'll have to leave this to Peter who can tell if these are new bugs or only problems in connection with the new GCC versions...

It seems as if the test compilation uses `pipec.c' twice from two different directories. It would be useful to see the output of `gpc -v' here, but currently I cannot promise to handle it with high priority. :-( Sorry for that.) > /tmp/cc0y2DBt.s: Assembler messages: > /tmp/cc0y2DBt.s:110: Error: operands given don't match any known 386 > instruction Doesn't this belong to `goto4'?

binaries for gpc on win98/NT platforms
by Scott Brown 25 Nov '99

25 Nov '99

I'm having trouble getting GPC up and running on my home pcs. It would make things very much easier if I could get some binaries instead of source code (as I haven't got the c/c++ compiler either!). Does anyone know where I can find a download site for such things? Do they even exist? Thanks. Scott.

Or in some cases I get a "cannot compile CRT > unit". That's strange. I can reproduce the problem under DJGPP with --automake, but it vanishes with --autobuild. To be sure, please remove all compiled crt*.o and crt*.gpi files once and try again. Did you try it on the command line, or only under rhide? If it works on the command line, but not in rhide, you'll have to edit rhide's settings (this was discussed on this list some time ago, but if you don't have the mails, I could find them). If it doesn't work on the command line either, please compile with `-v' (verbose), and send a complete log of the output.
