any reason to add that old version? (actual is 1.75.0)

[sebastian-bergt]

@SSE4 I need especially this version in a project I am currently working on as my dependency does not build with anything newer :(

[dmn-star]

A good chance to move your project forward.

There must have been some structural changes in the gap of versions

clang-linux.compile.c++.pch /home/conan/w/cci_PR-4354/.conan/data/boost/1.65.1/_/_/build/c13df43a378dae2d7b4adf9ab69eae873af52906/boost/bin.v2/libs/math/build/clng-lnx-8.0.0/dbg/bst.l-on/bst.l-off/lnk-sttc/thrd-mlt/../src/tr1/pch.hpp.pth
error: unknown argument '-emit-pth', did you mean '-emit-pch'?

Seems like the compiler flags set by that version (from September 7th, 2017) does not support newer compilers

Might be time to move to a newer boost version 🙊

[SSE4]

yes, 10 versions behind would be a huge challenge, you will end up back-porting lots of fixes for modern compilers, if would be much easier to just upgrade instead
