digitalmars.D.learn - DMD compiler choking?

reply Jeremy Gibson <jtgibson telus net> <Jeremy_member pathlink.com> writes:
I've been dabbling around with D source code for a while, but never actually
tried to compile anything just yet.  I finally got around to compiling one of my
projects, and run into this error on the very first class definition I have (if
I comment out any class with /+ +/, it always occurs on the very next class
definition in the file):

data.d(45): identifier 'Object' is not defined
data.d(45): Object is used as a type

What's worse, however, is that the compiler is encountering an assertion
failure:

Assertion failure: 'b->type->ty == Tclass' on line 284 in file 'class.c'

..which leads me to believe that the dmd compiler itself is flaking out.

Any insights?

If you post a cut-down (yet complete) code example that exhibits the  
problem you'll get a faster response :)

I'd say you've somehow got a broken installation? Sounds like the 
compiler cannot find the default -I path (usually pointing to 
dmd/src/phobos)

Sounds like the compiler doesn't know where to look for the library source
code.  After you extract dmd.zip, you have to edit (dmd.conf on unix
sc.ini) on windows and give DMD the directory where the phobos library
source is (it comes with the compiler).

To install the compiler, I extracted both dmd.zip and dmc.zip into my C:\dev
folder, such that the defaults should have worked just fine, assuming the % P%
evaluates correctly to the path to the current file as it's supposed to.

Since I didn't trust that completely, though, I just manually set the paths to
the following, replacing the relative paths with absolute paths, in order to
match up to the extracted paths precisely:

<sc.ini>

[Version]
version=7.51 Build 020

[Environment]
LIB="C:\dev\dmd\lib;C:\dev\dm\lib"
DFLAGS="-I C:\dev\dmd\src\phobos"
LINKCMD="C:\dev\dm\bin\link.exe"


..But I still have no luck -- the same errors are being thrown on compilation.
I just tried redownloading the compiler, also with no luck.

Maybe it just hates me? ;-)

I ask because I wanted to see if there were any clues in the  
compiler/linker output that might suggest something.

Have you added "C:\dev\dmd\bin" to your PATH?

Pretty much exactly similar to the first post on the thread, but I'll include
the command prompt and omit my witty banter for clarity.

I'm going to try adding those directories directly to my system's PATH

Still nothing.  Same errors through and through.

(I had actually added C:\dev\dmd\bin to my path a long time ago -- I needed it
in my path to be able to use the command-line compiler from my project folder,
after all.)

Ahh, of course. Yeah, at least one other person has had this exact same  
problem.

At the very least it should be documented. The compiler could error on  
compiling object.d, and/or refuse to create an object.o and/or refuse to  
link/see any object.o which is not in the main directory.

(cross posted to bugs, not sure if it needs a bugzilla entry?)

For what it's worth, I've run into this with Ares before.  DMD requires 
certain class definitions to be in object.d.  If it needs them and they 
aren't there, the compiler crashes.  But this should be reported, as the 
correct behavior would be to terminate with a helpful message.

DMD's phobos should rename the object module class to something 
inconspicuous like '_d_object' or something to avoid naming conflicts 
with new programmers. :) (I just thought naming conflicts with new 
programmers was kinda funny)

I think it should just go into std package, making it std.object
This way it'll be very hard to make the above mentioned mistake without

I'm all for this solution, for two reasons.  Reason 1, I've personally had a
project where 
I had a class whose most obvious natural name would be Object.  Of course, I
ended up 
calling it LObject, and renaming all its compliments with the L* prefix as
well, for 
consistancy.  It would've been nice not to have to.  Reason 2, it solves the
problem of 
what to do if I actually want to explicitly refer to the generic Object: just
call it 
std.object.Object (perhaps with an alias of _D_Object?)

I asked Walter to put object into std.object a long time ago. I don't 
think he ever responded to that request (i.e. if there's a reason why he 
won't do this, I don't remember what it is).

I also think that gcstats.d, unittest.d, crc32.d, etc. should be moved 
into the std module (or into "internal" or "etc").
