Hello,

I want to bring mtx to cygwin so I can use my changer
from windows.

I've download the source from
ftp://ftp.badtux.net/pub/storage/mtx/mtx-1.2.18rel.tar.gz

./configure looks ok for me but possible without scsi:

$ ./configure

But make is failing and I have no idea why:

$ make
gcc -g -O2 -DVERSION="\"1.2.18rel\""  -c -o mtx.o mtx.c
In file included from mtx.c:40:

Checking mtxl.h:

...
    28 #include "mtx.h"
    29
    30 void FatalError(char *ErrorMessage, ...);
    31 void *xmalloc(size_t Size);
    32 void *xzmalloc(size_t Size);
    33 void slow_bzero(char *buffer, int numchars);
    34
    35 DEVICE_TYPE SCSI_OpenDevice(char *DeviceName);
    36 void SCSI_CloseDevice(char *DeviceName, DEVICE_TYPE DeviceFD);
    37 int SCSI_ExecuteCommand(DEVICE_TYPE DeviceFD,
    38                                Direction_T Direction,
    39                                CDB_T *CDB,
    40                                int CDB_Length,
    41                                void *DataBuffer,
    42                                int DataBufferLength,
    43                                RequestSense_T *RequestSense);
    44
...

checking mtx.c:

...
     90 static DEVICE_TYPE MediumChangerFD = (DEVICE_TYPE) 0;
     91 static int device_opened = 0;  /* okay, replace check here. */
     92
     93 /* was: static int MediumChangerFD=-1; *//* open filehandle to that devi
     93 ce */
     94 static int arg1=-1;       /* first arg to command */
     95 static int arg2=-1;       /* second arg to command */
     96
     97 static SCSI_Flags_T SCSI_Flags = { 0, 0, 0,0 };
     98
...

Could anybody help me to identify the missing or problem?

Thank you,
Pierre Bernhardt
