It would be helpful if you could attach the main.log file showing the build failure with clang.

The code appears to be genuinely incorrect. Relevant errors are:

widgets.cc:356:15: error: redefinition of 'err' with a different type
                std::string err=handle_latex_errors(result);
                            ^
widgets.cc:350:26: note: previous definition is here
        catch(std::logic_error& err) {
                                ^

and

./youngtab.hh:602:18: error: invalid use of nonstatic data member 'rows'

                                      ^~~~

Temporarily blacklisted clang in r95560 until a fix can be applied.

gwright has retired. See #43784.

This should be fixed upstream as of 1.34. Cadabra 2 is also available BTW.

Update to 1.46

[jmroot (Joshua Root)]

Untested update to 1.46 attached. Can't be installed because modglue doesn't build, see #56523. Might be better to just switch to version 2.x.
