msvc vc 6.0 SP6 internal heap limit reached

[Ira]

All,

I am a newbie who is trying out the serialization library. In that article,
there is a demo program (demo.cpp) that i am trying to build. Along with
several warnings ('dynamic_cast' used on polymorphic type...), the compiler is
generating the following error:

fatal error C1076: compiler limit : internal heap limit reached; use /Zm to
specify a higher limit

I have tried various values for /Zm (200 is recomended) and either i still
receive this error, or if increase the value too much, the compiler generates
the following error:

fatal error C1204: compiler limit : internal structure overflow

Since this seesaw response doesn't seem correct, i am wondering if there is a
particular flag or combination thereof that would correct this problem?

Thank you.

This VC6 compiler limit can usually be worked around by spliting your source
into multiple ones.

HTH,

You can use values for /Zm as high as 800 or 1200. Have you topped
at 200 only?

I use /Zm800 when building boost - including the serialization library

I've been unable to make the demo.cpp to compile and execute successfully on
msvc 6. Same problem as you have.

My test matrix does show demo_xml building a running as advertised.

The test matrix shows a fair number of failures for msvc 6 - its the
platform with the worst results. I had to spend a lot of time just get it
to pass as much as it does.

If you expect to make good usage of boost you should find a way to upgrate
to VC 7.1 - its much, much better in this context.

Thank you to all who responded! To answer some questions:

Arkadiy Vertleyb:

In the recesses of mind i did know that one point :).
My thoughts at the time of the original post were that if i could not get "demo"
program to build, using this library in a large system (using VC6) might be an
excercise in futility.

Joaquin M Lopez Munoz:

I did increase the value of /Zm. At around /Zm400, the compiler generated the
following message:

fatal error C1204: compiler limit : internal structure overflow

For grins i took it up to /Zm1000, with no change (i was not expecting one).

Robert Ramey:

So, i'm not crazy! One less thing to worry about :).
Unfortunately, VC6 is what the client has on site and VC 7.1 just is not in the
cards right now.
So, it's back to a light weight serialization scheme until they can bring in a
new compiler.

For me the problem only occured when compiling a source that also generated
pre-compiled header-file.

My solution was to first build the pre-compiled headers via an empty source
file (e.g. stdafx.cpp).

After that the other source files compiled without problems.
