Compilation issues with Ubuntu 16.04LTS

[guest]

Dear Laura++ developers,

I have installed and run Laura++ in SL6 (gcc 4.4.7) with no issues. I recently tried to install Laura++ on Ubuntu 16.04LTS (gcc 5.4.0), but I get a lot of unused variable-errors (see make_withErrors.log for full list), such as:

inc/LauConstants.hh:89:18: error: LauConstants::pi defined but not used [-Werror=unused-variable]

const Double_t pi = TMath::Pi();

and compilation fails.

The code can be compiled by adding "-Wno-error=unused-variable" to the Makefile, though the compilation now spits out a very long list of warnings (see make_withWarnings.log), but it does appear to compile and run okay after this change.

Perhaps this is a compiler issue, but if so maybe you could add a note about this to the installation instructions?

Thank you very much,

Matt

Thanks for the report and apologies in the delay in acting on it. I don't have an Ubuntu machine on which to test this but have compiled without any warnings on Centos7 with gcc 6.2.0 (i.e. an even newer version). So it would seem to be something related to the specific compiler version (perhaps a bug even, since it looks like a spurious warning). I shall add a note to the doc/README file.
