[gobo-eiffel-develop] GEC bug report

[Wolfgang J. <wo....@ka...>]

Hi all,

today I downloaded the newest GEC version from GIT and tried to install 
it from scratch,
i.e. by running $GOBO/work/bootstrap/bootstrap.sh. It was, and still is, 
really terrible.

There are syntax errors in files gec2.c, gec17.c, then syntax errors in 
files
$GOBO/tool/gec/runtime/c/eif_file.c and eif_dir.c (probably causing the 
errors in the first files),
finally in the external C code of 
$GOBO/library/free_elks/kernel/file_info.e.

After fixing the syntax errors and adding option
   <option name="link" value="-pthread"/>
to the "gc" option in file $GOBO/src/gec/system.xace (probably 
Unix/Linux specific)
compilation works to some extend but issuing many warnings and finally
does crash definitively because of "missing kernel class *UNKOWN*".
The attachment contains the compilation messages.

Best regards
WJ

PS:
Installation platform:
- Linux 3.5.0-25-generic x86_64
- gcc version 4.7.2
- git commit d9f61c2e8ecf183634641470cc3ccfe39577b632

I'm sorry to hear about your bad experience.
The problem is that I don't have access to a system other than Windows.
So I was not aware of these problems. I tried to fix them the best that
I could based on your report. Please let me know if it's working better
for you.

Yes, it works better but not good.

Compiling file $GOBO/work/bootstrap/gec2.c issues the warnings
   gec2.c:206:32: warning:  character constant too long for its type 
[enabled by default]
(and a handful  more lines). There is the char literal '\177775'.
I guess that the gcc turns it into a 8bit literal by removing extra bits,
i.e. the warnings become semantic errors. I changed the occurrences
of '\177775' into the int literal 0177775.

Then the same warnings (and semantic errors) occur when the generated
gec compiles itself, now lines gec2.c:10203:13 etc., first in routine
   UTF_CONVERTER.escaped_utf_32_substring_into_utf_8_0_pointer
where line 312
   c := s.code (i)
(with `s: READABLE_STRING_GENERAL') is compiled into
   t4 = (T3)('\177775');
   t5 = ((T10)(t4));
I think that routines STRING_32.code or CHARACTER_32.code are to be 
modified.

Nevertheless, compilation continues (because we have warnings, not errors)
and ends again with errors of Eiffel compilation:
[GVKNL1] missing kernel class *UNKNOWN*.
----
[GIAAA] internal error.
----
[GVKNL1] missing kernel class *UNKNOWN*.

BUILD FAILED!

BUILD FAILED!


Then I replaced line 194 of STRING_32
    Result := area.item (i - 1).code.to_natural_32
by
    Result := area.item (i - 1).natural_32_code
and tried it again: the warnings and errors remain.
Here, I gave up.

It looks like you don't have the latest version of this file.
There is no literal '\177775' at lit 206 anymore.

Addition to the previous reply.

Sorry, I was confused when I recompiled the stuff.
Now I see that after modification of STRING_32 mentioned before
C and Eiffel compilation work very well.
