VERSION 2.3.3 Problems

Hi,

Actually for your system, (10.11)
I would advise that you download the official binary of gfortran:
http://coudert.name/software/gfortran-5.2-Yosemite.dmg

I have use that one (I have the same config as you) and it is working nicely. (I never use homebrew which is as you can see not up-to-date)

Cheers,

Olivier

It still fails, with the same error. I have downloaded a new version from scratch and I recompiled everything. Now my compilers are

Using built-in specs.

Since you install other version of gfortran, please check that all linker are the correct one. In my case, I have:

[@Oliviers-MacBook-Pro 2.3.4]$ which ld
/opt/local/bin/ld

In my case I have:

[rottoli@multivac:src]$> which ld
/usr/bin/ld
[rottoli@multivac:src]$> ld -v
@(#)PROGRAM:ld PROJECT:ld64-253.6

I have nothing installed in /opt/local/

Luca

oh I have another one:

[@Oliviers-MacBook-Pro 2.3.4]$ ld -v
@(#)PROGRAM:ld PROJECT:ld64-236.3
configured to support archs: i386 x86_64 x86_64h armv6 armv7 armv7s armv7m arm64
LTO support using: LLVM version 3.4

I also have the same as you:
@(#)PROGRAM:ld PROJECT:ld64-253.3.3
configured to support archs: armv6 armv7 armv7s arm64 i386 x86_64 x86_64h armv6m armv7k armv7m armv7em
LTO support using: Apple LLVM 7.0.0 (clang-700.0.72)

and I have tested using that one and it works nicely as well.
I’m assigning this to Marco, maybe he will have an additional idea.

Cheers,

Olivier

I have run 2.3.2 (which I downloaded using bzr) and I have additional info running in debug mode:

So it seems it may be a problem with fastjet. I have re-downloaded fastjet and recompiled it, but it looks like it is not finding it/linking it for some reason. I have set the fastjet path doing (in case it was not find automatically, it should be in my path)

set fastjet /usr/local/Cellar/fastjet/3.1.3/bin/fastjet-config

Did you try without fastjet (then we use fjcore which is the core of fastjet)

Cheers,

If I don't link fastjet it works - so maybe it was a problem related to how it is built.

Apparently it looks to be a problem related to lstdc++ - I had some problems in the past with fastjet related to that and I managed to solve them using the suggestion in https://github.com/davidchall/homebrew-hep/issues/26 - but this time the trick had not worked.

Now the problem seems to be lhapdf - I have to change lstdc++ -> lc++ since it couldn't compile, but I find another error...

BTW, thanks a lot for the suggestion to use fjcore! I didn't know it was shipped with the latest versions of amc@NLO
