Original valve's server code was compatible with linux and gcc 2.x Never gcc versions made restriction, that breaks build. Now, to make it build with gcc 4.x, you need do folowwing:
- Go to cbase.h and redefine macros as following
#define SetThink( a ) m_pfnThink = static_cast <void (CBaseEntity::*)(void)> (&a)
#define SetTouch( a ) m_pfnTouch = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (&a)
#define SetUse( a ) m_pfnUse = static_cast <void (CBaseEntity::*)( CBaseEntity *pActivator, CBaseEntity *pCaller, USE_TYPE useType, float value )> (&a)
#define SetBlocked( a ) m_pfnBlocked = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (&a)
#define ResetThink( ) m_pfnThink = static_cast <void (CBaseEntity::*)(void)> (NULL)
#define ResetTouch( ) m_pfnTouch = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (NULL)
#define ResetUse( ) m_pfnUse = static_cast <void (CBaseEntity::*)( CBaseEntity *pActivator, CBaseEntity *pCaller, USE_TYPE useType, float value )> (NULL)
#define ResetBlocked( ) m_pfnBlocked = static_cast <void (CBaseEntity::*)(CBaseEntity *)> (NULL)
...
#define SetMoveDone( a ) m_pfnCallWhenMoveDone = static_cast <void (CBaseToggle::*)(void)> (&a)
- Replace all SetThink(NULL), SetTouch(NULL), setUse(NULL) and SetBlocked(NULL) by ResetThink(), ResetTouch(), ResetUse() and ResetBlocked()
- Sometimes you may need to add #include <ctype.h> if functions tolower or isspace are missing
##VGUI library
Valve's client uses vgui library that is availiable only on x86 systems and has big amount of mistakes in headers. The best and simpliest way of porting is removing vgui dependency at all. Most singleplayer mods does not really use vgui it all. It used in multiplayer only to show score table and MOTD window
First, remove all files and headers, that uses vgui (contains "vgui" in file name).
- After that, try to build it and remove vgui includes.
- Remove all gViewPort usings.
- Redefine all DLLEXPORT defines as empty field (Place it under macro if you want to keep windows compatibility).
- Fix CAPS filenames in includes (like STDIO.H).
- Add ctype.h where it is need (tolower, isspace functions)
- Add string.h where it is need
- Add scoreboard_stub.cpp and input_stub.cpp from hlsdk-client to fix linking. Now you client should build and work correctly. Add input_xash3d.cpp from hlsdk-client project to fix input
