Re: isalnum not declared CODE

Re: isalnum not declared CODE

[Nikolai Nezlobin]

Dear All,

This is the short version of the code that produces the isalnum error.  The
files (agstring.h, CType.h, main.cc, makefile, makefile.common) and two
error messages (for the short code and for the whole project) are below.

All files, except for makefile.common, were in /mnt/hdb1/Sour/CType. The
line top=/mnt/hdb1/Sour in makefile reflects this. You will need to change
the top= if you try to compile the code.
makefile.common was kept one level upper (in /mnt/hdb1/Sour)

Thanks,
Nikolai

Re: isalnum not declared CODE

[Eljay Love-Jensen]

Hi Nicolai,

Your example (with some tweaking) worked on my platform.

My platform is Cygwin / WinXPpro (NT 5.1sp1a) and GCC 3.3.1 (cygming special).

The tweaking should be immaterial.  Things like putting in function bodies 
for String, changing #include <iostream.h> to #include <iostream>, adding 
in "std::" prefixes in the few spots they're needed, changing where top 
points to in the makefile.

Keep in mind that ctype.h is not part of GCC; it's supplied by your 
distribution (Slackware).

It appears that either your GCC was built for a different version of Slackware,
or... you have a filename collision (perhaps due to case insensitive 
filesystem?)
or... you could try putting #include <cctype> in your main.cc

Generally speaking, it's bad practice to name your project's header files 
the same as the system header files.  Even if they differ in case, such as 
<ctype.h> versus "CType.h".

Try this:
g++ -E -dI -c main.cc

That should show you if you are actually including the Slackware 
/usr/include/ctype.h as you expect.  I suspect you are not getting what you 
think you should be getting.

Sincerely,
--Eljay

The code you've posted works for me (albeit it would've been probably easier/better
if you just had attached a tarball so that one wouldn't need to fiddle with
the (badly formatted) "code text").

It did compile with GCC 3.2.3 and GCC 3.4 (both directly downloaded from a GNU mirror; 
i.e. no additional patches) and Redhat's GCC 2.96 on RH7.3 (installed from a RPM).

Either your distribution (it seems you're running a Slackware system and I don't have
any experience/knowledge about Slackware) has added a few patches and thereby 
unfortunately some bugs creeped in OR (what I suspect) something else gets in the
way before the right header is included (you don't have by chance a file named "ctype.h"
lying around somewhere in your source dir?). OR it's something completely different...

You can just run your code trough the C pre processor:

g++ -E main.cc > main.ii

Then, have a look at the main.ii file. 
Does it contain references to /usr/include/ctype.h? E.g:

# 1 "/usr/include/ctype.h" 1 3

If it does, is there some code which reads

extern int isalnum (int) throw ();

???

It should be there. Usually. ;-) 

Maybe you can try upgrading your compiler? I mean, GCC 3.2.3 is already a bit
dated.
