> When I try to compile anything, even the simplest program, I get: > /usr/i486-linux/bin/ld: cannot open crt0.o: No such file or directory Perhaps the versions of GCC and GPC you are using don't coincide. Please check the following: gpc -c myprogram.pas gcc myprogram.o -o myprogram i.e. compile with GPC, but link with GCC. Did you already check that crt0.o is in a directory where GPC can find it? I remember some problems when I had crt0.o in the directory /usr/lib/gcc-lib/i486-… [View More]

According to Berend de Boer: > Can we not simply see a C .h file as an interface-only module? I mean I can > simply import a c .h file which gpc parses and all symbols defined in that > header file are exported symbols? This would mean that GPC would have to parse C source. Remember that #include "foo.h" or (*$include "foo.h" *) just means that GPC treads the file `foo.h' just if its contents were written in our source file. A Pascal program using this mechanism would in fact look … [View More]

> Now I am looking out for reasonable ideas. Can we not simply see a C .h file as an interface-only module? I mean I can simply import a c .h file which gpc parses and all symbols defined in that header file are exported symbols? I don't know how far this is feasible. And it doesn't cover a.out modules creating using other languages (GNAT, ...). But it does cover the majority of cases you need externals. Groetjes, Berend.

I mean stuff like > 'fork()', 'exec()', etc... You can access any function using the "external", "C", and "asmname" directives: Procedure fork; external; means: there is an external Procedure "Fork" (first letter uppercase), Procedure fork; C; means: there is an external Procedure "fork" (… [View More]

Compilation error
by John Michael Black 03 Sep '96

03 Sep '96

Hi all. I've had this error ever since I installed gpc, and I've never figured out why. I'm not all that experienced at unix. When I try to compile anything, even the simplest program, I get: /usr/i486-linux/bin/ld: cannot open crt0.o: No such file or directory Sorry if this seems like such a stupid question. Any ideas? -john

Extended Pascal initialized *structured* variables are not (yet) implemented into GPC, only (parts of) Borland Pascal style initializers. However … [View More]
