Build against wxWidgets 3.2 as well as 3.3. Cemu raised its requirement to wxWidgets 3.3 in 08609591ae, but only 3.2 is packaged in Gentoo so far. The differences are small enough to bridge: * wxString::FromUTF8() gained a std::string_view overload in 3.3. The (pointer, length) and (const std::string&) overloads exist in both releases, so the affected call sites use those and need no version check. * wxInfoDC and wxScrollHelper::DoPrepareReadOnlyDC() are new in 3.3, and wxString::wc_string() is 3.3's name for ToStdWstring(). Guard those with wxCHECK_VERSION so the 3.3 code paths are picked up automatically once x11-libs/wxGTK:3.3 is available. The find_package() minimum is lowered rather than pinned, so 3.3 continues to satisfy it. diff -ruN a/CMakeLists.txt b/CMakeLists.txt --- a/CMakeLists.txt 2026-08-02 18:51:52.252716791 -0400 +++ b/CMakeLists.txt 2026-08-02 18:51:52.285160446 -0400 @@ -233,7 +233,7 @@ endif() if (ENABLE_WXWIDGETS) - find_package(wxWidgets 3.3 REQUIRED COMPONENTS base core gl propgrid xrc) + find_package(wxWidgets 3.2 REQUIRED COMPONENTS base core gl propgrid xrc) endif() if (ENABLE_CUBEB) diff -ruN a/src/gui/wxgui/CemuApp.cpp b/src/gui/wxgui/CemuApp.cpp --- a/src/gui/wxgui/CemuApp.cpp 2026-08-02 18:51:52.255147151 -0400 +++ b/src/gui/wxgui/CemuApp.cpp 2026-08-02 18:51:52.285353439 -0400 @@ -258,7 +258,7 @@ std::string TranslationCallback(std::string_view msgId) { - return wxGetTranslation(wxString::FromUTF8(msgId)).utf8_string();
