Re: [Quantlib-users] Boost 1.86 vs QuantLib 1.38

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

Hi Aaron,
    we use Boost 1.86 in our automated builds, as well as the latest 1.88.
QuantLib 1.38 builds and tests correctly with both (see
https://github.com/lballabio/QuantLib/actions/runs/16391531677/job/46318150792
or
https://github.com/lballabio/QuantLib/actions/runs/16391531677/job/46318150804
for a couple of examples on Linux, but we run similar checks for Visual
C++).  The same goes for the code that will be released shortly as version
1.39.
What compiler are you using? Do you get build errors while compiling
QuantLib itself, or while compiling some code of yours that uses it?  In
any case, I'll need to see your compilation log to check what the issue is.

Best,
    Luigi
