I did an svn update this morning, and noticing the large number of
changes, I decided to re-run the bootstrap.
Looking at History.txt, I see, amongst others:
This makes if possible for example for 'gec' to determine
--
whether the Boehm GC should be used trhough the Xace option
--
'garbage_collector'.
Apart from the two typos, the sentence seems to suggest that <option
name="garbage_collector" value="boehm"/> should now work.
But there is no confirmation of this in the section on gec itself. I
see that a compile_ge.xace file is generated and read, and the option
gets passed through to that file. But it looks like the option is
still ignored. Can you confirm that for the moment I still have to
type the gec command by hand to add the --gc=boehm option?

"It makes it possible" does not mean that it is already done. But it should be done anytime soon. I will open a bug report as a reminder. -- Eric Bezault mailto:er...@go... http://www.gobosoft.com |

Even if the environment variable BOEHM_GC is not set, gec will
generate code that works with the Boehm GC. Indeed, it is possible
that one wants to generate the C code, and then compile it later
on another computer where the Boehm GC is installed. Furthermore,
the environment variable BOEHM_GC is something that is used in
the config files in $GOBO/tool/gec/config/c, but it is just a
convention and it is possible to write config files that don't
use this environment variable.

<option name="garbage_collector" value="boehm" if="${BOEHM_GC}"/>

Update the file gobo/misc/eiffel.eant and try again.

Thanks. What happens if this option is supplied, but BOEHM_GC is not set? Is an error message issued, or does compilation go ahead assuming the value is actually set to "none"? If the former, then is it possible to test to see if an environment variable is set within a system.xace file? |

It doesn't work.
Not even if I add -DBOEHM_GC =/usr/local to the geant invocation.
Geant is not passing on BOEHM_GC to gexace command, and so the line
does not appear in the generated compile_ge.xace.
Here is the generated command:
gexace --define="GOBO_EIFFEL=ge GOBO_OS=unix GOBO_CC=gcc"
--system="ge" --output="compile_ge.xace"
/home/colin/gobo/src/gexslt/system.xace
If I manually add BOEHM_GC=/usr/local into the --define= stuff, then
the correct xace gets generated.

It didn't work. Actually I wonder how it could work on Linux.
I had to replace:
<option if="{GOBO_EIFFEL}=ge">
<option if="{BOEHM_GC}">
by:
<option if="${GOBO_EIFFEL}=ge">
<option if="${BOEHM_GC}">
The $ signs were missing. It's now fixed in SVN.
