[Insight-users] Problems building ITK 4 (eclipse & mingw)

[Sergio Vera]

Hello

I had the exact same problem

The problem is that there are two float.h in your system and they are being
found on the wrong order.
gcc float.h has the standard definitions while mingw float.h has also the
win32 required extensions.

Also, mingw's float.h has an * # include_next <float.h>* that tells your
compiler to look forward for an additional float.h. However, gcc's float.h
does not include such directive.  So if your compiler finds gcc's float.h
first, you will be lacking the definitions of some symbols.

Just search for gcc's float.h (mine was in
<MINGW_DIR>\lib\gcc\mingw32\<GCC_VERSION>\include\float.h)
and add an #include_next<float.h>

This should resolve your compilation issues.

Regards
