Re: gpc for Solaris 2.5.1

The 2.7.2-pre-release should (;-) be straightforward to compile under any system. First, compile the C compiler gcc-2.7.2 and let the object files in place. Then, unarchive gpc-1.2-2.7.2.tar.gz, cd to the gpc directory, type "./configure" and "make" -- voil`a. If you are successful, please let me know, so I can include the binaries into the distribution.

Nice to see that I am not the only one who likes it. Somebody who would like to help implementing it? Or to solve some other tasks (e.g. write documentation), so I am free for it?

So with EMX, GPC will have to create a correct .def file as well. Probably somebody here knows how to compile a shared library for Linux or other UNIXes with GPC? Somebody willing to write a documentation section about this?

OS/2 DLL's
by phy0a0＠spf1.power.uni-essen.de 12 Oct '96

12 Oct '96

Hello, After some experimenting, I produced an OS/2 dynamic link library (DLL) with GNU Pascal that I could call from another application. Perhaps this is common knowledge but I do not see it documented anywhere. The following seems to work compiled with the latest emx distribution of GPC using "gpc -Zomf -Zdll cube.pas cube.def": unit cube; { a simple function in a DLL} interface function cubit(x:integer):integer; implementation function cubit(x:integer):integer; begin cubit := x*x*x; end; end. You have to be careful in the module definition file to list the function with only the first letter capitalized or LINK386.EXE will complain: /* module definition file for Cube dll */ LIBRARY CUBE EXPORTS Cube @1 Allan D.

Locate the section [gcc] and copy it into a new section [gpc] The variables in each section are passed to this program as environment variables, but they don't clutter your real environment.

You _should_ be able to use these, if you declare them properly as external C style functions. These are the functions who's names start with __dpmi.

Some more output would be nice, so we know which test(s) failed. Please add "-v" to the compiler flags in the Makefile, then rerun the tests. --- "Nothing shocks me, I'm a scientist", Indiana Jones

getenv()
by John Michael Black 10 Oct '96

10 Oct '96

OK, I got the declarations to compile perfectly, but how do I use the function? It's not compatible with string types, so I can't do any assigning or string-testing. Here is how I declare the function: function getenv(s: __CString__): __CString__; C; Is there a way to assign the result into a string? -john

Hello, I have a Problem with the gpc-1.2-2.7.2 under Sun's SunOS 4.1.4.
