digitalmars.D.ide - Descent with gdc

reply Jason House <jason.james.house gmail.com> writes:
I'm setting up a new system and I only have gdc on it at the moment.

When I go to windows->preferences->d->installed compilers, and enter gdc as
the type and name, I initially get a "libraries can not be empty" error. 
After adding the library folder (tango), I get no error but can't click ok. 
Entering a compiler home directory erases what I put in the libraries area
and gives the error "Target is not a DMD installation Root.  DMD executable
was not found"

Am I mistakenly trying to use descent with gdc?  Is the error text bogus and
I'm entering the home directory incorrectly?

Any tips would be greatly appreciated.

I just tested it and it works, although I found a bug I already created a ticket for (56). I did this: - In compiler type, select gdc - Click the "Browse..." button and select your gdc directory. That directory should have a bin folder with gdc inside it. Now, if you are on Windows, "gdc/inlcude/d/3.4.5" is going to be suggested as the standard library. Press ok, go to edit the compiler you just created, remove the library and add tango as an external include path (if you do it without saving, exiting, and editing, it doesn't work... that's the bug). If you are on linux, no standard library should appear. Add tango as an external include path, press ok, go to edit, and add it again (because of the bug). If this still doesn't work (strange), you can try creating a symlink "gdc/include/d/3.4.5" to the tango folder. Maybe you can trick Descent that way (or a hardlink? Sorry, I don't know much about linux). But... re-reading your post now, maybe you didn't change to "gdc" compiler type, because of the error message you get: "Target is not a DMD installation Root. DMD executable was not found" :-)

The DMD error message is certainly strange. I did select the compiler type correctly as GDC. I'm using linux, and here's as far as I get: Compiler type: GDC Compiler name: gdc Compiler home directory: /usr/bin Compiler system libraries: /usr/include/d/4.1.3 (Error at bottom) Target is not a DMD installation Root. DMD executable was not found. Ok button is greyed out and the "?" icon does not do anything.

I will check that later when I'll have time.

As a workaround, because the compiler is not used yet (just the path to 
object.d and the rest of the files), just ignore the "installed 
compilers" page, right click the project you are working on, properties, 
d build path, and in the "libraries" tab add the include paths for 
tango, phobos, or whaterver.

I don'e even reach that point.

DMD executable was not found) I even have not understood what I need to put in libraries paths. :( Thank you very much for any help. Bye.

I've done Ary's workaround (not listing installed compilers and
adding /usr/include/d/4.1.3 to the include path), and stuff is almost
working.  I have two files that compile correctly from the command line but
give errors in descent: "No return at end of function", "line 6".

At a minimum, the line numbers are way off.  It says the error is on line 6
but highlights line 4.  Both of those lines are within a large (GPL)
comment at the top of the file.  Any idea what could be going wrong?

The simpler source file with this problem is attached.

Solution: turn of descent semantic errors ;-). Go into Project > Properties > D Compiler and set "show semantic errors" to "none". It's still a *very* alpha-stage feature.

I'm using Descent 0.5.1 on Linux, installed just yesterday, and it is 
working fine with gdc (with one problem). I entered /usr as the location, 
and Descent found everything ok.

The problem is that gdc puts config.d and fonfigunix.d into a platform-
specific subdirectory of /usr/include/d/4.1.3 called i486-linux-gnu. This 
makes a lot of sense because this is the code that has to be different on 
different architectures.

Unfortunately Descent won't let me add this directory to the library 
paths because it is inside the main one. I worked around this by copying 
the two files I needed into /usr/include/d/4.1.3/gcc.

It would be nice if Descent would sort this out for me.

Other than this (and building of course), Descent is really great.
