[Insight-users] Re: Compile problems - Red Hat Enterprise WS-3; c make 2.0.2 ; ITK from CVS ; DICOM parser subdirectory

[Fred Nugen]

I had the same problem (see below) as the user who originated this
subject line around early July, and I found a workaround which may 
elicidate the issue.  I also have supporting results using a simple test case.

I am compiling ITK 1.8.0 using CMake 2.0.3.

My solution was not to setenv $CC and $CXX before ccmake'ing.
I am not sure what compilers were used as defaults, and I do not
know how to find out.  I had previously set both to gcc.  (I do not
know what compilers/options were invoked by the command "gcc", and
I do not know how to find out.)  I assume they do something reasonable
(see test case below).

I originally set these values to the best thing I could think of, since I was
instructed to do so in the GettingStarted.txt file.  In retrospect, I should
have known better, but I figured the configuration process would tell me
if there was a problem.

At the bottom is the original error exactly as found, and some info
on the machine/OS used.  Here is are the results of the test case
suggested in the original thread.

The error I received was as follows.  In receiving
this error, I setenv'd $CC and $CXX both to gcc.

The ccmake settings used:

Line 51 of DICOMFile.h reads:
 bool Open(const dicom_stl::string& filename);


I think I have correctly tracked the error down to the cmake check
labelled "does the compiler support std:: ".
The answer seemed to be no (I see the definition
CMAKE_NO_STD_NAMESPACE="1"), and so the code ultimately
defined the macro dicom_stl to be empty in DICOMConfig.h:
#ifdef DICOM_ABOUT_NO_STD_NAMESPACE
 #define dicom_stl
#else
 #define dicom_stl std
#endif


Without setenving the $CC and $CXX variables
 cozumel:~> echo $CC
 CC: Undefined variable.
 cozumel:~> echo $CXX
 CXX: Undefined variable.
the code compiled without errors:
