Re: Cannot link from gcc 3.x.x, using gplc object

Idomeneo a écrit :

The best way to do this is to use the -v option of gplc to see how it
invokes gcc. Then you adapt the command-line.

Similarly for the link phase (you will see gplc also includes -lm for
math).

Good luck

Hello,

I'm trying to compile and linking the example main_new (in folder
ExamplesC, in gprolog folder) from my gcc 3.4.6 (instead than gplc
[1.3.0], likewise the book taught) and I cannot do that!

That's how I'm trying:

- Create two object files with:

$> gcc -c -o new_main_c.c -I ../src/EnginePl

$> gplc -c new_main.pl

( with option "-I", I'm simply telling to gcc where to find
gprolog.h)

- Linking them together with gcc with:

$> gcc -o new_main new_main.o new_main_c.o -lbips_fd
-lbips_pl -lengine_pl -lengine_fd -llinedit -L ../src/EnginePl -L
../src/BipsPl -L ../src/BipsFD -L ../src/EngineFD -L ../src/Linedit/

(with "-L" options I tell to the gcc where to find libraries)

It seems pretty clear (almost to me) but it doesn't work at all
and I absolutely can't figure out why!!

Below you can see output of what I get when I try to compile like I
write above:

I don't know what to try or do, any advice or help would be nice; I
really need to get rid of this!

Thank you really much!
