Hi there,

I am using latest trunk code and declared a bool type variable in
i386.h as below:

extern bool mybool;

And then configure gcc as:

../gcc/configure --enable-languages=c,c++ --disable-bootstrap

During the stage of libgcc build, I then ran into following errors:

make[3]: Leaving directory

It seems that C files include this, so you'll want _Bool, or just use an int.

Thanks for your reply. I know I can use the int. But the bool type is
more precise. And now GCC is in C++, the bool type should be
supported. I am curious whether this is a missing part of GCC. Can
someone please help to confirm?

BR,
Terry

But if you search i386.c, you will find many bool type variables. Why
it works for i386.c but not for i386.h?

i386.h is a header, it's not only used in one place.

I assume your error is because i386.c is compiled as a C++ file, but
i386.h is included in a file that is compiled as a C file, e.g.
libgcc.c

Yes. I have same understanding. Is it possible to compile libgcc.c as
a C++ file?

The i386.c is compiles as

while the libgcc2.c is compiled as a pure C file. For GCC we have
something like GCC in C++, will we have something like LIBGCC in C++?

I don't know.  The public functions in libgcc are all C functions, so
would (at least) need to be declared extern "C" if compiled as C++.

IMHO the best solution would be to  #include <stdbool.h> in i386.h

Thank you all. I did learned something behind the question. All of
your solutions can work. I will pick up the one that is fit for my
