Compiling with emscripten

[abeimler]

Hi,

I am experiencing a compiler error when using emscripten (compiling to wasm) since the latest update.

In file included from libs/fixed_containers/include/fixed_containers/fixed_circular_deque.hpp:4:
In file included from libs/fixed_containers/include/fixed_containers/fixed_deque.hpp:14:
libs/fixed_containers/include/fixed_containers/random_access_iterator.hpp:171:37: error: no member named 'iterator_' in 'RandomAccessIterator<ConstEntryProvider, MutableEntryProvider, CONSTNESS, DIRECTION>'
  171 |         return Self(std::next(other.iterator_, n));
      |                               ~~~~~ ^
1 error generated.

Looking into RandomAccessIterator<ConstEntryProvider, MutableEntryProvider, CONSTNESS, DIRECTION>, it appears that iterator_ is not a member. This raises the question of why it compiles successfully with gcc.

Notes:

• Compiler: emcc/emc++ 3.1.61 emsdk up-to-date from git
• Compiler: gcc 14.1.1 (compiles successfully)
• CMake: 3.28.1
• OS: Arch Linux (Kernel: 6.9.5)

/bin/ccache /usr/lib/emscripten/em++ -isystem vcpkg_installed/wasm32-emscripten/include ... -Os -DNDEBUG -std=c++20 -fcolor-diagnostics -fcolor-diagnostics -Wall ... -MD -MT ...

some warnings and include paths, but nothing special

I has not set up or cross-compiled the fixed-containers project itself with emcc; this issue arises in my other projects that build with emcc. The compilation works fine with gcc, but not for the web build.

This issue occurs with a personal fork of fixed-containers, which is up-to-date with the current main branch.
