Hi,
I have the following error when I run configure:
checking size of wchar_t... configure: error: cannot compute sizeof (wchar_t)
what can I do ?

Study config.log for the source of the problem.

Thank you Martin. How can I remove -lgcc_s and use the Intel equivalent ?

I think he wanted YOU to find the problem. The best way to learn is to figure it out yourself! Good luck. |

I'm not so sure that there is anything wrong in configure. configure doesn't pass -lgcc_s to icc; instead, icc is making this up on its own. So I would guess you need to get libgcc_s onto you system in a way that the linker finds it. Else you need to read the icc documentation (but I'm fairly sure that icc is *required* to link with libgcc_s, for interoperability with gcc-compiled binaries).
I'm somewhat puzzled that the wchar_t test is the one where it crashes; this test comes fairly late, and configure has run multiple compiler invocations before that.
Can you build any binaries at all with your icc installation?

Yes of course, I successfuly built and installed nmap, wget, so I thought there was something in the python configure process.
If didn't investigate everything but I solved the problem by adding the "-static-libgcc" option:
CFLAGS="-w -static-intel -static-libgcc"
I think one should commit changes so configure can manage this. I can I want to help for further diagnosis or improvement. Also it seems -Wall will be deprecated, and usually we use -w:
-w<n> Control diagnostics, where <n> is one of the following:
0 -- Display errors (same as -w)
1 -- Display warnings and errors (default)
2 -- Display remarks, warnings, and errors
Cheers, Mathieu |

Yes WDC I know, but for some problems 1) we can gain much efficiency with getting help from guys that are familiar with the environment and 2) we also allow the committers to know a problem and improve the sources. That's the way an open source group works IMHO :)
Now that the problem is solved for me, it is for all MacOSX+Intel icc guys.
Cheers, Mathieu |

I don't think that change should be made. I'm almost certain that it is correct. Many people build Python with icc, and never reported any such problem. So there must something be wrong with your icc installation.
