how to compile dcmtk for wince(arm architecture)?

[jixiang]

hello,everyone,I have complied dcmtk successfully on win32 using vs2005,but our project is running on wince ,now,I need rebuild the dcmtk.I selcect the config manager "OMAP_3530(ARMV4I)" and compile it with vs 2005,there were a lot of error.

I found some problems but I didn't solve them:

(1)wince use unicode but the dcmtk use the char ;

(2)some functions about time such as time(),gmtime(),localtime() are not surportted by wince.

what can I do??
how to config the CMakeLists.txt for wince?

[Michael Onken]

Hi,

ad 1: DCMTK does not support any character sets, it just reads each byte from the DICOM file as it is. So you should be able to use Unicode on top of DCMTK but you will have to convert to char if you give it to DCMTK. There should be functions for that on Win CE.

ad 2: We have no experience to build DCMTK for current Windows CE systems. But in general, you would have to detect this platform in the code and use #ifdefs in order use the time functions of Windows CE instead.

Best regards,
Michael

[jixiang]

thank you, you said detect the system,how to config the cmakelist for wince.

/*cmakelist.txt*/

# declare project
PROJECT(dcmtk)

# check for Windows operating system
#IF(NOT WIN32)
#MESSAGE(FATAL_ERROR "Please use GNU autoconf for Unix systems.")
ENDIF(NOT WIN32)

how to modify it to detect wince or use what macro ?
thanks.

I'm not sure whether CMake already supports Windows CE (this is something you should probably check on the CMake website and/or mailing list).
However, you should definitely switch to the latest snapshot of DCMTK instead of using the "old" release 3.5.4.

With regard to Windows CE support for DCMTK: We have investigated this a couple of years ago but neither had the time nor the requirement to actively support it. A colleague of mine had checked the required changes at that time but did not finish this job (as far as I know). Regarding the ASCII/Unicode issue: There are conversion macros (e.g. USES_CONVERSION and A2T) that can be used for this purpose (as far as I know).

At Present, firstly,I try to compile the ofstd package because all of the other packages depend on it.

in ofstd package: oftime.cxx,ofdate.cxx,ofdatime.cxx,offname.cxx
the four functions have some funtions about processing time with CRT.I
use some functions on wince to take the place of them. there still are a lot of problems :
1. wince have not such include files :cerrno and io.h.(included in ofstdinc.h)
checking the source code , the ofstd.cxx need the errno macro in cerrno and access function in io.h.I use GetFileAttribute instead of access(line 400 in ofstd.cxx),but I have no idea to solve the errno macro reference.

2. I know we have to interconvert in char and unicode.the question is
that all of the files refered to char need to convert ,the job is huge.whether there are other good methods to process it.

the following is the code I modified in ofstd package.I don't know whether right or not .If someone interests in it,we can discuss it.

Wince处理进程的函数和win32不一样，用相关的函数替换。

wince没有io.h文件，io.h有函数access的声明，注释掉io.h，用GetFileAttributes替换掉access。


#ifdef HAVE_IO_H

wince didn't have io.h,removing it and using GetFileAttribute to take the place of the access.

I have compiled ofstd package successfully.the dcmdata and dcmnet packages have some errors. I read in websites that wince doesn't support getenv() function and strerror (errno) function.suggest me the ways to solve this problem.

[Michael Onken]

Hi,

I don't have any inisight, but maybe searching on google already gives some ideas, like this one.

Good luck!
Michael

[jixiang]

solved question:
I have replaced the strror(errno) with a wrapped function GetErrorMessage.
the code:
#include <errno.h>
#include <Windows.h>
#include <strconvert.h>

int GetErrorMessage(char* errorMsg)
{
DWORD dwError = GetLastError();
DWORD systemLocale = MAKELANGID(LANG_NEUTRAL,SUBLANG_NEUTRAL);
BOOL fok = FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER |
FORMAT_MESSAGE_IGNORE_INSERTS,
NULL,
dwError,
systemLocale,
AnsiToUnicode(errorMsg),
0,
NULL);
if(!fok)
{
printf("fail to obtain errmsg\n");
return 0;
}

return 1;

}


unsolved qustion:

An old qustion is that wince have not the concept of environment variable.
how to get the "DCMDICTPATH" to load data dictionary?how to replace the function getenv()?

some source codes in dcmtk:
// environment variable pointing to the data dictionary file
#define DCM_DICT_ENVIRONMENT_VARIABLE "DCMDICTPATH"

OFBool
DcmDataDictionary::loadExternalDictionaries()
{
const char* env = NULL;
int len;
int sepCnt = 0;
OFBool msgIfDictAbsent = OFTrue;
OFBool loadFailed = OFFalse;

env = getenv(DCM_DICT_ENVIRONMENT_VARIABLE);
if ((env == NULL) || (strlen(env) == 0)) {
env = DCM_DICT_DEFAULT_PATH;
msgIfDictAbsent = OFFalse;
}

if ((env != NULL) && (strlen(env) != 0)) {
len = strlen(env);
for (int i=0; i<len; i++) {
if (env == ENVIRONMENT_PATH_SEPARATOR) {
sepCnt++;
}
}

if (sepCnt == 0) {
if (!loadDictionary(env, msgIfDictAbsent)) {
return OFFalse;
}
} else {
char** dictArray;

dictArray = OFstatic_cast(char **, malloc((sepCnt + 1) * sizeof(char*)));

int ndicts = splitFields(env, dictArray, sepCnt+1,
ENVIRONMENT_PATH_SEPARATOR);

for (int ii=0; ii<ndicts; ii++) {
if ((dictArray[ii] != NULL) && (strlen(dictArray[ii]) > 0)) {
if (!loadDictionary(dictArray[ii], msgIfDictAbsent)) {
loadFailed = OFTrue;
}
}
free(dictArray[ii]);
}
free(dictArray);
}
}

return (loadFailed) ? (OFFalse) : (OFTrue);
}

[Jörg Riesmeier]

I my opinion, there is no need to support the DCMDICTPATH environment variable on Windows CE. You should probably just use the built-in data dictionary and/or use the default path specified in the macro DCM_DICT_DEFAULT_PATH.

[Michael Onken]

Hi,

then you will not be able to run DCMTK servers in multi-process mode which maybe is ok on a windows CE system. Just change the code to always return an error if someone tries to call it in your system. You might also want to prohibit the compiler from compiling that original code part by surrounding it with #ifdef (I think it is #ifndef _WIN32_WCE" but dont know for sure) if you do not want to change it.

Best regards,
Michael

the line will result in illegal indirection. I find that the definition
of stdin and stdout has some different between win32 and wince.

the definition in win32:

#ifndef _STDSTREAM_DEFINED
#define stdin (&__iob_func()[0])
#define stdout (&__iob_func()[1])
#define stderr (&__iob_func()[2])
#define _STDSTREAM_DEFINED
#endif

the definition in wince:

// Std handle defns
#define stdin _getstdfilex(0)
#define stdout _getstdfilex(1)
#define stderr _getstdfilex(2)

// functions for general buffered file handling in either ANSI or Wide
_CRTIMP __checkReturn FILE* __cdecl _getstdfilex(int _FileHandle);

At present ,storescu,storescp,echoscu have compiled and run sucsussfully. storescu.exe can run on wince and transfer file from wince to win32 platform (my pc).Thank all friends.

At the beginning,I compiled the dcmnet using cmake and conifged the platform for wince in vs2005.There will be a lot errors because
wince and win32 have different lib and head files.there are some unsolved qustion.
Later,I give up the cmake and create new project and add related resource files and head files into my project.In this way,you can obtain a real wince environment.then,you can do some work to replace the win32 fuctins or overwrite some functions.
In addition,you need pay attentions toi nternal dependencies .so,you should comiple the lib follow the sequence.if someone have interested in it ,we can discusss it .good luck.
