[gobo-eiffel-develop] Include path for Boehm GC

[Colin A. <col...@go...>]

I was compiling tonight on my Linux box in London. I installed Boehm
7.0 (rather than 6.7 which I installed at home) as that is what I was
able to install on Windows.

However, when it got to the C compile stage, errors were coming out
that it couldn't find gc.h.

I took a look, and I saw that the header files had been installed into
$BOEHM_GC/include/gc
. So I have copied them to the parent directory and I trying again.

It may be therefore that the gcc.cfg file I checked in only works with
6.7 and not 7.0. I shall check on this at the weekend (if the compile
now works).

This is odd, because under Windows it is looked in $BOEHM_GC/include.

I guess you can put both paths in your include variable.

Well, it might just be different file-system standards. Anyway, I will
check this weekend what I have at home.

It compiles now, and works correctly.

Unlike on Windows.
That is, transformation involving file URIs work, but if I try to use
http, it crarshes (low memory access).

Which is why I was trying it tonight, as I wasn't sure if I had tested
that bit on Linux with gec.

So I guess this is a problem in the area where eposix and gec are
interacting. Although I couldn't swear to it working on Windows with
ISE, as I haven't compiled it for some time.

The problem is I can't easily test it - my AXA Rosenberg laptop with
Windows on is virtually unusable at the moment due to a dodgy
keyboard.

How do you mean?

gc_includes: -I$BOEHM_GC/include -I$BOEHM_GC/include/gc

Actually, there is the possibility of using gcc with Windows (I don't
know if gec currently supports this). Perhaps there should be
conditional logic? Or maybe just stick to the simple solution of
including both

What do you think Eric?

Yes, Bernd managed to make it work I think.

Or we should have another configuration file gcc_win.cfg. I don't
know which solution is best. For the time being I tend to prefer:

gc_includes: -I$BOEHM_GC/include -I$BOEHM_GC/include/gc

Good.

Bernd, did you do any performance comparison tests for msc v. gcc
compiled binaries?

No, all I have done was to compile Gobo under Windows and run the test  =

suite to see if everything works. I am rarely using Windows myself.

In general, it should not be difficult to do. Is there any benchmark sui=
te  =

available for Eiffel? All I know about is the benchmark suite for  =

SmartEiffel that they use for the "language shootout" page.
