_cppyy_backend.py causes error in python 3.11
In python 3.11 file.open("rU")
(_cppyy_backend.py:95) cling/python/cppyy_backend/_cppyy_generator.py:95
causes an error. Removal of the U
solves this issue without apparent side effects.

Build from source failure on undeclared identifier _POSIX_SEM_VALUE_MAX
(Reporting here rather than cppyy repo because this issue is specific to the build here.)
I'm attempting to follow the instructions for building from source
Start with the cppyy-cling package (cppyy-backend repo, subdirectory “cling”), which requires source to be pulled in from upstream, and thus takes a few extra steps:
$ git clone https://github.com/wlav/cppyy-backend.git $ cd cppyy-backend/cling $ python setup.py egg_info $ python create_src_directory.py $ python -m pip install . --upgrade
This fails for me on two different systems and three compilers
Ubuntu (with clang16 or gcc11.4) and Fedora36 with gcc12.2
(Should I retry with other or older compilers?)
The SEM_VALUE_MAX
error starts with commit 00c7bed
"upgrade Cling from upstream (28.04)"
(before that commit there's another blocking error - a compile fail on a const
qualifier).

`You are probably missing the definition of std::allocator<char>::deallocate(char*, unsigned long)`
Unexpected behavior when building cppyy-backend master-branch from source using g++ >= 10.
- Have to pass -D_POSIX_SEM_VALUE_MAX=32767 flag manually or the following error occur:

static constexpr ptrdiff_t _S_max = _POSIX_SEM_VALUE_MAX;
- After that I manage to build and install it in python. However when I run python code a few link error occur, the following one is one of them
import cppyy
cppyy.cppdef("""
#include <string>
void f() { std::string mPath; }
""")
from cppyy.gbl import f
f()
and error message is
IncrementalExecutor::executeFunction: symbol '_ZNSaIcE10deallocateEPcm' unresolved while linking symbol '__cf_4'!
You are probably missing the definition of std::allocator::deallocate(char*, unsigned long)
Maybe you need to load the corresponding shared library?
Building using g++-9 works great and both errors disappear. I assume it's more stable however some of the c++ codes that I am planning to expose to python only compile on newer compilers.
What might cause these link errors?
Any help is appreciated~

cppyy_get_all_cpp_names doesn't return all the names it should
Hi!
For this code:
namespace GG {
struct S {
int a;
int c;
S(int a, int c): _a{a}, _c{c} { }
S(): _a{0}, _c{0} { }
};
}
Calling cppyy_get_all_cpp_names(handle_of_S, &count)
returns just ["S", "~S“]
. Data members are not included.
Also, it would be great to extend cppyy_get_all_cpp_names
to work with any namespace, i.e. to return the names of classes, structs and all the other entities that are declared inside a namespace.
