compiling DCMTK-3.6.1_20140617 with Libiconv on GNU/Linux

Hi,
I'm compiling the latest snapshot (DCMTK-3.6.1_20140617) on Debian GNU/Linux Stable and everything works perfectly fine except that I can't enable the support to libiconv.

===
configure:14207: checking whether to include libiconv support
configure:14240: c++ -o conftest -I/usr/include/libxml2 -D_REENTRANT -D_XOPEN_SOURCE_EXTENDED -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -D_BSD_COMPAT -D_OSF_SOURCE -D_POSIX_C_SOURCE=199506L -Wall conftest.cpp -lrt -lpthread -lnsl -liconv -lcharset >&5
conftest.cpp: In function 'int main()':
conftest.cpp:259:44: error: 'NULL' was not declared in this scope
configure:14240: $? = 1
configure: failed program was:
| /* confdefs.h */
==========

I have figured out that configure fails to check libiconv because there's no libiconv. In fact the libiconv package does not exist anymore, because on Linux, libiconv is now part of libc (since at least 2006)

My question is: what is the trick to enable libiconv on GNU/Linux ?

I guess there are 2 options:
1/ Force dcmtk to use the glibc's version of iconv but I have not figured how yet.
2/ Compile and install libiconv manually, and finally compile dcmtk. However, I suspect there will be conflict between the two versions of libiconv (the one from libc and the one from libiconv)

How do you guys have successfully enable iconv on GNU/Linux ?

Regards,
Damien

The latter works, i.e. "2/". Using the glibc version of the iconv functions is still on our to-do list...

Hi,
here is a quick update for those interested in using the latest snapshot with iconv enabled:
* I have not been able to successfully use iconv with the libc.
* there is a bug opened by the dcmtk packager so you can have an update
