Fmt made breaking changes. You either download fmt 9.0 or apply latest changes from tfs
https://github.com/otland/forgottenserver/blob/283c5405d0fc6e3dc346ec3f64d0423f9ec3ba1f/src/tools.h#L79

@ErikasKontenis Do u know how can I install fmt 9.0 from vcpkg? Or can you help me with applying latest changes from tfs? idk if should I apply in tools.h or in iomarket.cpp or in core.h where the error is point to this:

'template <typename Context, typename T>
FMT_CONSTEXPR FMT_INLINE auto make_value(T&& val) -> value {
auto&& arg = arg_mapper().map(FMT_FORWARD(val));
using arg_type = remove_cvref_t<decltype(arg)>;

constexpr bool formattable_char =
!std::is_same<arg_type, unformattable_char>::value;
static_assert(formattable_char, "Mixing character types is disallowed.");

// Formatting of arbitrary pointers is disallowed. If you want to format a
// pointer cast it to void* or const void*. In particular, this forbids
// formatting of [const] volatile char* printed as bool by iostreams.
constexpr bool formattable_pointer =
!std::is_same<arg_type, unformattable_pointer>::value;
static_assert(formattable_pointer,
"Formatting of non-void pointers is disallowed.");

constexpr bool formattable = !std::is_same<arg_type, unformattable>::value;
static_assert(
formattable,
"Cannot format an argument. To make type T formattable provide a "
"formatter specialization: https://fmt.dev/latest/api.html#udt");
return {arg};
}'

@ErikasKontenis I have installer fmt 9.0 but now I'm facing another issue:
