First I would seriously suggest that you add the -save-temps flag to you CFLAGS.
This saves the intermediary files for inspection.

Second, you are using programs from the /beta directory compiled with djdev204
or djdev205.  Some of them have been compiled with NLS support enabled.  The NLS
support is provided by the gettext and iconv libraries that have been compiled
as DXE3 modules.  This means that the programs like make or grep have been linked
with these DXE3 modules or dlls.  No mather if you like/use/enable/disable NLS on
your system the libraries MUST be installed because the programs linked with them
try to find them at start.  If they cannot be found then the program aborts with
an error output like this:

H:\q2dos>make
libintl.DXE: module loading failed (No such file or directory (ENOENT))
Abort!

Installing gettext and iconv is mandatory.


Third, I have tried to compile the q2dos sources using my 205 installation
and it failed with  the following error message:

gcc -g2 -Wall -O0 -save-temps  -I wattcp/inc -Did386 -DREF_HARD_LINKED -DGAME_HARD_LINKED -DUSE_DOS_CD -DOGG_SUPPORT -DCLIENT_SPLIT_NETFRAME -DGAMESPY -I libogg/inc -I libvorb/inc -c client/cl_input.c -o client/cl_input.o

                  from client/client.h:30,

An inspection of time.h from djdev205 shows that the following lines are the
crucial ones:


#include <sys/cdefs.h>

unsigned long long _rdtsc(void);

_EXTERN_INLINE unsigned long long
_rdtsc(void)
{
#if ((__GNUC__ == 4 && __GNUC_MINOR__ >= 8) || (__GNUC__ > 4))
   return __builtin_ia32_rdtsc();
#else
   unsigned long long result;
   __asm__ __volatile__ ("rdtsc" : "=A"(result) );
   return result;
#endif
}



The important issue here is to understand that the inclusion of sys/cdefs.h
provides the definition of the macro _EXTERN_INLINE.  An inspection of the
preprocessor file shows that the WATT32 package provides its one version of
sys/cdefs.h stored in C_INCLUDE_PATH=/dev/env/DJDIR/net/watt/inc
and this version seems to inhibit the expansion of _EXTERN_INLINE,
causing the compiler abort.  Futher investigations needs to be done to see
how the headers of WATT32 port needs to be fixed.


 From the preprocessor output:


# 1 "wattcp/inc/sys/cdefs.h" 1 3 4
# 49 "wattcp/inc/sys/cdefs.h" 3 4
# 1 "wattcp/inc/sys/cdefs.h" 1 3 4

        struct mbuf *next;

        char *data;
        unsigned cnt;
      };

unsigned long long _rdtsc(void);

_EXTERN_INLINE unsigned long long

{

   return __builtin_ia32_rdtsc();





}
