Re: [Quantlib-dev] QuantLib-1.42.1 not building on a GCP Ubuntu VM

[Luigi B. <lui...@gm...>]

Hello—when you say Boost is under a sub-dir of /usr/include, do you mean
you have (for instance) /usr/include/boost/config.hpp, or it is
/usr/include/some-dir/boost/config.hpp?

Also, looking at config.log will show the actual compiler error that gcc
emitted when it tried to include some Boost header.  That might help.
