Boost 1.76 beta - linking error when including Boost
Hello,
I'm afraid I don't have a minimal example yet, but I thought I'd give
you a heads-up in case it rings a bell.
I've been trying the Boost 1.76 beta to build a library I'm maintaining.
The library builds, but when I link it to an executable I'm getting an
"undefined reference to `bool boost::math::isnan<long double>(long
double)". Everything works with 1.75 and earlier. My code is not using
boost::math::isnan directly, so I'm guessing some other included boost
component is forward-declaring it or doing something similar?
The linking error disappears if I
include
Hello, I have a minimal example now. The program:

The linking error disappears if I include
in a config file that is included by every file in the library. Today I'll try to pinpoint the problem by removing it there and including it before specific boost headers in the source files, but as I said, I'm posting this in case someone already has an idea about the underlying issue. Thanks, Luigi

Luigi, I opened a PR to address your issue. See: https://github.com/boostorg/math/pull/580 Matt
Thanks!

Thanks Matt! Baring in mind that these are "just" missing #includes, are these too late for the release now? Matt: I'll file a PR shortly that updates our tests on this, though I'm curious how they slipped through - certainly the log1p case should already be tested for (sf_log1p_incl_test.cpp).
