Hi,
This is either a false positive from gcc 4.4 or a regression in gcc 4.6.
Please note that the minimum gcc version on Linux supported by the MITK
team directly for 2014.03 is the default gcc from Ubuntu 12.04 (which is
gcc 4.6). If you need continued support for gcc 4.4 you might want to
consider submitting a CDash nightly client to the MITK dashboard so we
can keep an eye on possible regressions in the future.
We could add an additional condition for the Connectomics modules at the
location you pointed to, like ${GCC_VERSION} VERSION_EQUAL "4.6".
Best,
Sascha

Hi there,
we updated our MITK to 2014.03, and I now get the error pasted below.
I'm on Scientific Linux, 6.1, with gcc 4.4.7-4, and I only get it when
building in Release and not Debug mode. Interestingly:
https://github.com/MITK/MITK/blob/master/Modules/DiffusionImaging/Connectomics/CMakeLists.txt#L13
So, this has come up before with versions 4.8(+), What motivated the
choice of 4.8(+)
Even more interestingly, our nightly builds on gcc 4.6.3, 4.6.4,
4.8.1, 4.8.2 all seem to complete.
So, what to do?
If someone can advise me, I can prepare a patch.
Thanks
Matt
