I had a problem with a missing (..\) include path in the debug version
of sgc.lib, I haven't checked yet the latest git branch but I might have
messed up the .sln myself while creating the x64 configurations.

I am actually calling scheme_set_stack_base().
The issue is: I am adding a racket interpreter to a GUI (Qt) application
and I cannot simply call scheme_main_setup() and run a REP loop from
within a function passed to scheme_main_setup(). I basically need to
create/initialize an interpreter at initialization and then evaluate
expressions at a later time.
I now have something that seems to work but no idea if it's the right
approach (probably not, and apparently I cannot use it with 3m);
something like:
Scheme_Env* Init()
{
...
int dummy;
scheme_set_stack_base( &dummy, 1 );
Scheme_Env* e = scheme_basic_env();
...
scheme_namespace_require(scheme_intern_symbol("scheme/base"));
...
return e;
}
Thanks

I was able to make the racket embedding code work...
...but now I have another problem: When I try to call scheme_basic_env()
the program crashes with an access violation error (reading location 0x0
so it's probably due to a NULL pointer).
I cannot perform any further debugging because I was not able to build
racket in debug mode, I tried to build debug versions of the libraries
but Visual Studio reports a missing .\debug\sgc.lib file.
Is there a way to build everything in debug mode ?

You should be able to build the DLLs using MSVC and selecting the
"Debug" project. But that actually just turns off optimization;
debugging ".pdb" files are generated with the "Release" build.
I'm not sure why he debugger wants "sgc.lib", since that's used only
for the "SGC" project. Try building the "SGC" project, and then
re-build the "Release" project, and maybe that will make the debugger
happy.
But are you calling scheme_basic_env() directly? Normally you should
use scheme_main_setup() or scheme_main_stack_setup(), which sets GC and
thread parameters before calling scheme_basic_env().
