FYI, we are only able to support platforms for which nightly testing submits to our dashboard:
https://open.cdash.org/index.php?project=CMake [^]
Instructions to run a testing dashboard client are here:
http://www.cmake.org/Wiki/CMake/Git/Dashboard [^]
Currently a few HP-UX versions and architecture combinations are submitting and are clean as of commit 594dd9b3 in 'master':
B.11.11 9000/785 gcc
B.11.11 9000/785 aCC
B.11.23 ia64 aCC
B.11.31 ia64 aCC
Some of these were only recently added and some post-3.2 fixes were made for them. Does our Git 'master' build for you? Do you have a different os/arch/compiler combination? |

> B.11.11 9000/785 aCC
Actually this submission is only running the test suite but uses the gcc-built cmake binary because that compiler can no longer build CMake itself. |

The compiler is HP gcc version 4.7.0. Uname reports "HP-UX B.11.23 U ia64" for the OS/Arch.
Building from the Git master gives me the same problem, with the error "'finite' was not declared in this scope". |

Re 0015576:0038783: I don't have access to any of these system. Will you please propose a specific modification/patch to the preprocessor logic? |

Sure I'll try and come up with a patch proposal over the next couple of days.
I've been trying to determine if it's an issue with HP-UX itself (the c/c++ library I guess?) or the GCC we're using, but the documentation available isn't great and the behaviour is odd (using isfinite with gcc is fine, but using it with g++ isn't).
Thanks for the quick replies by the way, great support for CMake! |

Looking at the math.h which its including from /usr/include/math.h, I can see why its not picking up isfinite...
# if defined(_PA_RISC) || !defined(__cplusplus)
...
# define isfinite(x) _ISFINITE(x)
I'm guessing its a bug and it assumes that c++ code will use cmath (which works on this server) instead of math.h.
Could the following change be made to the CMake cpp file?
BEFORE:
// HP-UX
#if defined(__hpux)
# if !defined(isfinite)
# define isfinite finite
# endif
#endif
AFTER:
// HP-UX
#if defined(__hpux)
# if !defined(isfinite)
// Some versions of HP-UX don't define isfinite in math.h for C++ Itanium, so we
// have to use the internal version instead
# if defined(__ia64) && !defined(finite)
# define isfinite(x) (sizeof(x) == sizeof(float) ? _Isfinitef(x) : _Isfinite(x))
# else
# define isfinite finite
# endif
# endif
#endif
