build error on ubuntu

[Ryan Dou]

hi, everyone. I am a newbie. when I build the dcmtk3.6.3 on ubuntu 18.04 with cmake and make, it has an error. the content is:

[ 17%] Building CXX object dcmdata/apps/CMakeFiles/xml2dcm.dir/xml2dcm.cc.o

what can I do next? thanks very much!

can anyone help me? is this unicode error? but why it present "No such file or directory"? Is it because there is no library file? thanks.

I guess that your system's libxml2 library has been compiled with LIBXML_ICU_ENABLED defined. The following excerpt is from the listed libxml2 header file "/usr/include/libxml2/libxml/encoding.h":

Code: Select all

#ifdef LIBXML_ICU_ENABLED
#include <unicode/ucnv.h>
#endif

Does the DCMTK compile if you disable the use of libxml2 (see INSTALL file)?

I got it! Thanks so much!
