executing in xCode, serious problems in Mac Os X!!

[esmitt]

Hi,
i installed dcmtk following the steps in the installation guides (zlib, tiif, libxml, libpng, tcp_wrappers and libicinv) for MacOs X.
In /usr/local/dicom exists bin, etc, include, lib, man and share subdirectory. I suppose that all is correct.
When i write a test code in Xcode IDE:

Code: Select all

#ifndef HAVE_CONFIG_H
#define HAVE_CONFIG_H

#include "dcmtk/config/osconfig.h" 
#include "dcmtk/ofstd/oftypes.h" 
#include "dcmtk/dcmdata/dctk.h" 
#include <iostream>

int main (int argc, char * const argv[]) {

	DcmFileFormat fileformat;
    std::cout << "Hello, World!\n";
    return 0;
}
#endif

The compilation is 0 errors and warning but the execution crash! the message is:

Code: Select all

[Session started at 2007-10-16 12:11:02 -0400.]
ZeroLink: unknown symbol '__ZN13DcmFileFormatC1Ev'

I change the option ZeroLink in Build Options and the same result.
If you can help me....maybe my installation process is wrong but i don't know how verify that. I have installed the software as 4 or 5 times!!!!

Thanks in advance


p.d.: my OS is version 10.4.10 in a Mac based Intel

Hi,

I also think this is link problem in Xcode due to wrong configuration. Be sure to link at least the DCMTK libraries ofstd and dcmdata to your project.

If DCMTK builds correctly on the console it is very unlikely that the problem lies within the toolkit.

[Per]

Are you compiling the program as C++ code (set with the suffix .cpp rather than .c)?

Thanks...
I will review the link to the dcmtk library... it's my first steps in Mac!!! and in xCode too.
The file is a .cpp extension. I shall try to make the compiled without use xCode (emacs or vi editor)

Thanks...

Hi, i executing in the terminal with my file main.cpp and the default output a.out. Mi dicom libraries are in /usr/local/dicom...

Code: Select all

g++ main.cpp -I/usr/local/dicom/include/ -L/usr/local/dicom/lib/libdcmdata.a -L/usr/local/dicom/lib/libdcmnet.a -L/usr/local/dicom/lib/libdcmdsig.a -L/usr/local/dicom/lib/libdcmimage.a -L/usr/local/dicom/lib/libdcmimgle.a -L/usr/local/dicom/lib/libdcmjpeg.a -L/usr/local/dicom/lib/libdcmpstat.a -L/usr/local/dicom/lib/libdcmqrdb.a -L/usr/local/dicom/lib/libdcmsr.a -L/usr/local/dicom/lib/libdcmtls.a -L/usr/local/dicom/lib/libdcmwlm.a -L/usr/local/dicom/lib/libijg12.a -L/usr/local/dicom/lib/libijg16.a -L/usr/local/dicom/lib/libijg8.a -L/usr/local/dicom/lib/libofstd.a

...and nothing
if you can help me about this..

thanks in advance[/code]

Before calling your post "serious problems in Mac Os X" you might want to read the manual page in the future. The -L option specifies a link directory in g++, -l with lowercase l specifies a library to link against. Also note that link order is significant and probably wrong in your example - there is some FAQ that explains the library dependencies; libraries need to be specified in reverse order of dependency, i.e. typically -ldcmdata -lofstd are the last DCMTK link statements. You can also see this in the various DCMTK makefiles.

Ok, maybe it's not a correct title for my post, sorry for that and i thanks for your recommendations.
