[Insight-users] can't build (ITK) hello world

[Luis Ibanez]

Hi John,

Thanks for the quick response and
the detailed answer.

1) The size looks right,
    what I see in my Ubuntu build for ITK-3-6
    is 4,633,530 (which is close enough).

2) Your read permissions look right

3) The simplest way is to look at the
    CMakeCache.txt files of both your
    ITK-3-6 build and your HelloWorld build.
    search for "CMAKE_CXX_COMPILER"

4) The versions look fine.


Additional things to check:


    Since the original message said that ld
    couldn't read the symbols... please do
    the following:


5) check what version of "ld" you are using.
    ld --version

6) use nm on the library, just to check if
    you see a list of symbols. The command
    will be:

     nm -C /usr/local/lib/InsightToolkit/libITKCommon.a



Please let us know what you find,


     Thanks


        Luis
