* Revert "Linux: Fix failure to run VeraCrypt binary built for console mode on headless machines (fix issue https://github.com/veracrypt/VeraCrypt/issues/531)" The build failure still exists for system wxGTK compiled with '--disable-gui': ``` In file included from TextUserInterface.cpp:27: TextUserInterface.h: In member function ‘virtual bool VeraCrypt::TextUserInterface::Initialize(int&, wxChar**)’: TextUserInterface.h:50:63: error: ‘wxAppBase’ has not been declared 50 | virtual bool Initialize (int &argc, wxChar **argv) { return wxAppBase::Initialize(argc, argv); } ``` This reverts commit 737e1f126b8826ed02418266e590e195aebdd7c0. * Revert "Linux: fix compilation error when building console-only version of VeraCrypt that is statically linked to wxWidgets" The build failure still exists for system wxGTK compiled with '--disable-gui': ``` In file included from TextUserInterface.cpp:27: TextUserInterface.h: In member function ‘virtual bool VeraCrypt::TextUserInterface::Initialize(int&, wxChar**)’: TextUserInterface.h:50:63: error: ‘wxAppBase’ has not been declared 50 | virtual bool Initialize (int &argc, wxChar **argv) { return wxAppBase::Initialize(argc, argv); } ``` This reverts commit 14bee5e6a227701e78c5fec04064c0494f6361f0. * src/Main/Main.make: simplify the WX_CONFIG_LIBS logic Irrespective of whether we are linking against widgets statically or dynamically, pull in only 'base' when GUI is disabled, and 'adv,core,base' when GUI is enabled. When GUI is disabled, the C/CXX flag must include '-DwxUSE_GUI=0' for this to work. * src/Makefile: pass '-DwxUSE_GUI=0' when NOGUI=1 veracrypt with NOGUI=1 fails to properly link against wxGTK compiled with '--disable-gui' only using the 'base' library because the wx's setup.h implicitly defines wxUSE_GUI=1, which then changes the definition of various structures, requiring symbols from the core library as well. For example, wxwidgets include/wx/app.h defines: #if wxUSE_GUI class WXDLLIMPEXP_CORE wxAppBase : public wxAppConsole ... [snip] ... #else // !GUI // wxApp is defined in core and we cannot define another one in wxBase, // so use the preprocessor to allow using wxApp in console programs too #define wxApp wxAppConsole #endif // GUI/!GUI To fix this, pass '-DwxUSE_GUI=0' when compiling veracrypt with NOGUI=1.
