I found the following problem when trying to make the wrapper:

The following example:

#include <NNPDF/lhapdfset.h>


int main(void){
	auto pdf = NNPDF::LHAPDFSet("NNPDF31_nlo_as_0118", 1);
	auto x = new (NNPDF::LHAPDFSet)(pdf);
	delete x;
}

compiled with:

#meson.build
project('nnpdf', 'cpp')

deps = [dependency('nnpdf'), dependency('lhapdf')]

executable('exe', 'xx.cc', dependencies:deps)

Segfaults somewhere in the destructor:

$ ./exe 
PDF: NNPDF31_nlo_as_0118  ErrorType: No Errors booked
LHAPDF 6.1.6 loading /usr/local/share/LHAPDF/NNPDF31_nlo_as_0118/NNPDF31_nlo_as_0118_0001.dat
NNPDF31_nlo_as_0118 PDF set, member #1, version 1; LHAPDF ID = 303401
NNPDF31_nlo_as_0118 Initialised with 1 members and no errorType.
fish: “./exe” terminated by signal SIGSEGV (Address boundary error

I'll try to see where exactly.
