gforth 0.7.0 can't find libcc.h

[vladimir.kupcov@…]

There was no errors during compilation, but I can't use C functions interface. When I'm trying to call C function I see bunch of error messages. Here is the example:

First string in temporary C source code is

That's what "see compile-wrapper-function1" says:

Looks like gforth trying to find "gforth/0.7.0/libcc.h" in "/opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_lang_gforth/work/destroot/opt/local/include", which is not exist. I guess it's temporary directory which was created by MacPorts and removed after gforth was installed. Is there any way to fix it? I think correct path should be "/opt/local/include".

Thank you,

What do I need to type to reproduce this problem? I'm not familiar with gforth.

[vladimir.kupcov@…]

In my example there was few functions from ncurses.h, but you can try to call any C function. Here is what you need to type to call abs from stdlib.h:

\c #include <stdlib.h>
c-function stdlib_abs abs n -- n
-3 stdlib_abs .

gforth should show "3 ok", but instead there will be error messages saying "gforth/0.7.0/libcc.h: No such file or directory" and "libtool compile failed". If you save this code to test.fs and run "gforth test.fs", you'll get something like this:

/Users/vladkupcov/.gforth/libcc-tmp/gforth_c_1010588D0.c:1:32: error: gforth/0.7.0/libcc.h: No such file or directory

/Users/vladkupcov/.gforth/libcc-tmp/gforth_c_1010588D0.c:7: error: 'sp' undeclared (first use in this function)

in file included from *OS command line*:-1
test.fs:3: libtool compile failed
-3 >>>stdlib_abs<<< .
Backtrace:
$101004990 throw 
$101040500 c(abort") 
$101040C70 compile-wrapper-function 

And if you type

see compile-wrapper-function1

gforth will show you piece of Forth code with path to C include files for libtool, just like in my first message. I think this path should be "/opt/local/include".

Hopefully this will help.

Thank you,
