maybe we are looking at 2 different versions of webtoolkit. but the one I see requires:
Cmake (2.4 or 2.6 are preferred) and boost-1.35 or later.
http://www.webtoolkit.eu/wt#/download [^]
g++ 4.3.3 is compiled against the current gmp and libmpfr they are "requirements to build", that is g++ will not build without them.
please confirm the URL of the software you are attempting to compile.
as well as the OS version and configure command
I don't think the problem is with g++ being incompatible with libmpfr. I think it is more the latest wt is not compatible with the older version of libmpfr.
I will wait for your reply and data before making the final determination.

The problem seems to be related to using the sqrt() from <cmath> which uses the g++ __builtin_sqrt(). To remove WT from the picture, I created a main.cpp with the following:
int main(int argc, char **argv)
{
double d = __builtin_sqrtf(2.0);
return 0;
}
If I compile this using:
g++ main.cpp
I can reproduce the problem
My OS is Solaris 10.
My libmpfr is version 2.3.1,REV=2008.01.29
My g++ is version 4.3.3,REV=2009.05.07
The libmpfr and g++ versions are what pkg-get -u installs when I get from current.
If I download and build the latest libmpfr, then __builtin_sqrtf() compiles successfully. |

thank you for the feedback, I will look into this further.
we are in the process of upgrading gmp and then libmpfr so hopefully once I get that done, this bug will be fixed as a side effect. |

ok, using the sample program you gave me I cannot reproduce:
$ g++ m.cpp
$ ./a.out
I get no error
I tried on solaris 8 sparc, and 10 sparc and 10 x86
Here is the pertinent software I am using.
all the systems have the same revision of CSW software
$ pkg-get -c libgmp libmpfr

what version of libgmp are you running? is there any other info you can supply? |

Hello there, I built a new gcc version: 4.6.1. It's available from the unstable repository. I also updated libgmp, libmpfr, libppl and libcloog. Please give the new packages a go. |

I'm waiting for feedback. If I don't receive any until the end of November, I'll close it. |

I believe this is fixed now, with gcc-4.6.2 in the unstable catalog, both the compiler and the library have been rebuilt from scratch.
If it's still a problem, please open a new bug, or talk to us at #opencsw on Freenode. |
