In PR98885#C1 Nathan said that "an exported entity must be so-declared on its
first declaration".
Would it be possible to forward-declare every exported entity and then
`#include`ing all the headers?
I mean something along the lines:
$ cat borrar.h
namespace Test
{
template<typename T>
class valarray {};
}
$ cat borrar.cpp
export module Test;
namespace Test
{
export
template<typename T>
class valarray;
}
#include "borrar.h"
$ cat main.cpp
import Test;
int main()
{
Test::valarray<double> v;
return 0;
}
$ g++-11 -Wall -Wextra -fmodules-ts borrar.cpp main.cpp
main.cpp: In function ‘int main()’:
main.cpp:6:26: warning: unused variable ‘v’ [-Wunused-variable]
6 | Test::valarray<double> v;
| ^
However, I don't think that this approach can be used to split the library into
several modules.
