@yurivict Finally got around to fixing some of these errors. If you have time, could you try with the current repo and let me know the results?

[d-m-bailey]

@yurivict I've made changes to the source to handle most of the warning/errors. They're on the clang-13 branch.

git clone -b clang-13 https://github.com/d-m-bailey/cvc.git

There are probably still problems with src/mmappable_vector.h because it has 4 compiler specific directives.
For example:

#ifdef __GNUC__
#if __GNUC__ == 3
                        A *the_allocator = static_cast<A*>(&(this->Base::_M_impl));
#else

Do you know how to implement this for the clang-13 compiler?

Do you know how to implement this for the clang-13 compiler?

No.

What does this code achieve? How are regular containers insufficient?

[yurivict]

STL vector generally can't be mmapable because it can generally resize any time.
If you need a deep modification like this - then you would be better off writing your own class from scratch.

The project fails to build with gcc-12 as well: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=266189

Thanks for the information, the gcc-12 fail looks like it has to do with the cdlParser.c which is bison output.

As for the mmap, I think I was trying to reduce the real memory required by essentially forcing the data to disk. I think the array sizes were fixed when allocated.

[yurivict]

Yes, it's never a good idea to use STL container inner structures, because there are many implementations of STL. Having a custom class for mmapped vector seems like the way to go.

Currently the cvc's FreeBSD port doesn't build with clang, and it also prevents GCC upgrade to 12 because it fails with gcc-12.

@yurivict Does adding the the following line fix the problem?

diff --git a/src/Cvc.hh b/src/Cvc.hh
index 8df45c1..c01d04b 100755

FYI
This maybe off-topic (not related to clang).
But I can confirm that: include fixes the cdlParser.cc fail on gcc 13.1.0.
Maybe this fix also works for gcc-12, but sorry I don't have gcc-12.
