Guile 1.8.2 Compile Error

Guile 1.8.2 Compile Error

[ericbambach1]

Hello,
        Please CC Im not subscribed.

        When compiling on AIX 5.3 using IBM's supplied GCC 4.0.0 I get 
this error.
-------snip-----

However, the only '.' token is in the comments!

I tried seeing what the preprocessor thinks of the file, but I couldnt 
tell much from that either.

Any ideas? Please tell me it's fiaxable or theres a workaround as 
upgrading the compiler is not an option yet. I need guile so I can run the 
testsuite on a new compiler. AIX has all sorts of weird issues so I can't 
user a compiler I cant test.

This corresponds to the following declarations:

  typedef void  *(*scm_t_c_hook_function) (void *hook_data,
                                           void *func_data,
                                           void *data);
  SCM_API void scm_c_hook_add (scm_t_c_hook *hook,
                               scm_t_c_hook_function func,
                               void *func_data, 
                               int appendp);
  SCM_API void scm_c_hook_remove (scm_t_c_hook *hook,
                                  scm_t_c_hook_function func,
                                  void *func_data);

Can you please try compiling a C file including similar declarations to
see what's going on (normally `SCM_API' expands to `extern')?

Thanks,
Ludovic.

Caveat Emptor: While I've had quite a bit of experience compiling code
and debugging basic syntax errors and os-specific mis-assumptions, I've
not had the need to be a C/C++ code-jockey of any more skill (yet) than
to write anything more complex than output hacks for something as simple
as hello.c (*toe*). :q

Recap:
I'm having a problem compiling guile 1.8.3 on AIX 5.2 using gcc
4.2.2, that's pretty much identical to the problem reported on guile
1.8.2 (and using the same gcc as previously reported on 1.8.2 I get the
same error as previously reported). The error for 1.8.3 looks like this:

In file included from ../libguile/gc.h:27,
                 from ../libguile.h:73,
                 from discouraged.c:22:
./libguile/hooks.h:43: error: expected ';', ',' or ')' before '.' token

./libguile/hooks.h:63: error: expected ';', ',' or ')' before '.' token
./libguile/hooks.h:66: error: expected declaration specifiers or '...' before 'scm_t_c_hook_function'
./libguile/hooks.h:67: error: expected ';', ',' or ')' before '.' token
gmake[3]: *** [libguile_la-discouraged.lo] Error 1

Were you asking to just put the quoted code lines in a .c file and see
what happens when I apply gcc to it, or were you looking for something
more specific?  I'm willing to do whatever you like, but I might need a
more specific set of directions (possibly an example of the code you
want me to test)?

In the hopes it's something simple -- if test.c is:
---cut---

  typedef void  *(*scm_t_c_hook_function) (void *hook_data,
                                           void *func_data,
                                           void *data);

  SCM_API void scm_c_hook_add (scm_t_c_hook *hook,
                               scm_t_c_hook_function func,
                               void *func_data,
                               int appendp);

  SCM_API void scm_c_hook_remove (scm_t_c_hook *hook,
                                  scm_t_c_hook_function func,
                                  void *func_data);

---cut---

and I do gcc -o test test.c ... I get ...

test.c:6: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'
test.c:11: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'

Which are the SCM_API declarations.

Now if I include all of the subsections that report error lines from the
libguile compile, test2.c looks like (line numbers from original code -
not in .c):

---cut---
41:
42: typedef void *(*scm_t_c_hook_function) (void *hook_data,
43*                                         void *func_data,
44:                                         void *data);
45:
46: typedef struct scm_t_c_hook_entry {
47:   struct scm_t_c_hook_entry *next;
48*   scm_t_c_hook_function func;
49:   void *data;
50: } scm_t_c_hook_entry;
51...60
61: SCM_API void scm_c_hook_add (scm_t_c_hook *hook,
62*                              scm_t_c_hook_function func,
63*                              void *func_data,
64:                              int appendp);
65: SCM_API void scm_c_hook_remove (scm_t_c_hook *hook,
66*                                 scm_t_c_hook_function func,
67*                                 void *func_data);
68:
---cut---

I get ...
test2.c:12: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'
test2.c:16: error: expected '=', ',', ';', 'asm' or '__attribute__' before 'void'

Which are the SCM_API declarations again.

Suggestions, correction for a more valid / informative test?

Just to head off the inevitable, Yes, the gcc build I have does build
working binaries/libs. I can build (for example) something as intensive
and make-check breakable as gmp 4.2.2 with no problems.  

Guile 1.4.1 builds cleanly and passes all of 'make check' on this
platform. Guile 1.6.8 builds a (seemingly) working copy (but 'make
check' gives about 20 errors on srfi-4.test - everything else passes
fine).

This is the second line of the typedef for `scm_t_c_hook_function'.  Can
you try compiling *only* that typedef?  And then this:

  typedef void * (* foo_t) (void *, void *);

Then:

  typedef void (* foo_t) (void *, void *);

The `scm_t_c_hook_function' seems perfectly valid to me so if the
compiler chokes, then I'm afraid it's a broken compiler.

The former.

So now the typedef itself doesn't yield any error?

Did you prepend "#define SCM_API extern"?  It will fail without this.

Again, no error with the typedef?

> Suggestions, correction for a more valid / informative test?

If one of the above `foo_t' typedefs works, then you can try compiling
this:

  extern void make_foo (void *x, foo_t function);

Then maybe this:

  extern void make_foo (void *x, foo_t *function);

This is all trial-and-error since I have no idea of what's wrong with
this compiler.

I quickly browsed the bug database at gcc.gnu.org and failed to find
anything related.  You might want to try that too...

Thanks,
Ludovic.
