Re: BP and BO question...

According to Jim Roland: > I am in need to use the GetEnv function (and the SetEnv) function along > with other borland functions. Does your system support a `setenv()' C function? Mine (Linux) does, but I was told that it is not part of all standards. Since `man setenv' yields int setenv(const char *name, const char *value, int overwrite); I can declare an equivalent GPC function as follows: Function SetEnv ( Name, Value: CString; overwrite: Integer ): Integer; C; (And similar for `GetEnv'.) > [BO5, BPcompat] > How do I compile both? I can't get either to compile, and there don't > seem to be complete instructions to compile them. Currently, `BPcompat' only (?) supports DJGPP out of the box. Be welcome to help us to add support for UNIX systems. BO5, OTOH, is intended to be completely portable. Unfortunatly, those versions you can find on Agnes are somehow obsolete; I am currently working on a complete new implementation of BO5 (version 0.1 rather than 0.01;-) which uses `ncurses' for terminal I/O on UNIX-like platforms. Using GRX for graphics I/O (including X11) is in preparation. > Eventually, I would like to be able to modify the sources from the BP5 > library source code that I have (Borland, permitting of course) and use > them to include in my programs--possibly make it part of the GNU library > if they will allow it. Sorry for being that sceptical, but I doubt (a) that Borland will agree to use *anything* from their code in a LGPLed library and that (b) it would be useful for us at all because Borland's code is highly specialized for MS-compatible DOS systems. IMHO it will be less work and cause fewer legal problems to re-write the needed code from scratch. Again: Be welcome to join us in performing this task.

Hi, Larry! Hi, all!

I don't know, but if you are looking out for something really current with GPC, go to ftp://agnes.dida.physik.uni-essen.de/gnu-pascal/ instead.

Hello! According to Jim Roland: > I have just installed GPC 2.0 (is there a newer one than this 12/96 > version?), and I'm having a problem running configure/make.

Version problem
by Jim Roland 06 Feb '98

06 Feb '98

I have just installed GPC 2.0 (is there a newer one than this 12/96 version?), and I'm having a problem running configure/make. When I configure (I had to remake my gcc-2.7.2.2) i get a version error that GPC 2.0 requires gcc-2.7.2.1, which I have 2.7.2.2! It's frustating since that is a newer version, and I'm excited about possibly using GPC with the borland extensions since I'm a borland pascal person! :) BTW, in code, how does one access the environment variables? Also, how do you reference items that were part of the borland units (DOS, SYSTEM, etc)? ====================================================================== Jim Roland, running the most stable operating system in the world: OS/2 v4.0--I TALK to my OS, and IT LISTENS, does yours? ----------------------------------- Running Internet Servers on OS/2 & Linux (a free & stable Unix OS) ----------------------------------- Get free PGP software today to keep your files & messages private!

Re: gpc installation problems on Digital Unix

Hello! According to Gary Narayanan USG: > > 1. The compiler (I think is gcc 2.7.2.1 compiles this and not > /usr/bin/cc) could not compile the file "gpc-decl.c" . The > error was in line 2962 > > TREE_CODE (TREE_VALUE (tail)) = code; > > The compile said it was not an l-value. > > I worked around by eliminating the conditional, and typing > > return NULL_TREE; > > for both cases. Will this break the compiler functionality? Yes. It must have been `/usr/bin/cc' since gcc-2.7.2.1 is known to accept this. The problem comes from the `TREE_CODE' macro being a type cast which is not accepted by all C compilers as an lvalue. To work around, replace the line by (TREE_VALUE (tail))->common.code = code; > 2. The file "gpc-module.c" has several '#define' statements and > not starting at first character of the line. The link editor > failed because of this, eg > > ld: unreolved STORE_SPECIAL Fixed. Thanks. > 3. The rts/Makefile generated needed some editiong, ie > adding a "../" for the gcc path name. Here I am not sure. Maybe this comes from some VPath problem? Anyway, more recent versions of GPC have an automatically generated `rts/Makefile' which hopefully does not cause this problem.

Re: Passing strings by value

Kevin A. Foss: > Is there something special that needs to be done to pass > strings by value? Yes, there is: fixing a bug in GPC... :-( This is a known bug, and will be solved sooner or later. In the meantime, you might have to use the obvious workaround, making a local copy of the string in the function. Thanks anyway for the bug report, Frank -- Frank Heckenbach, Erlangen, Germany fjf(a)gmx.de http://home.pages.de/~fjf/links.htm
