static_cast error when building test data generators

[evanmiller]

I'm trying to build the test data generators in math/tools. I'm running the command ../../../b2 in that directory. However, the command just spews out errors such as:

What am I doing wrong? Here is my compiler info if it helps:

$ clang++ --version
Apple clang version 12.0.0 (clang-1200.0.22.19)
Target: x86_64-apple-darwin19.5.0
Thread model: posix

Thanks

I'll look into it, those are sort of archived for future reference and probably haven't been built in a while :(

[jzmaddock]

Issue confirmed, working on it....

[jzmaddock]

See #392.

[jzmaddock]

Fixed in develop I hope now!

[evanmiller]

I now get the following compiler error:

clang-darwin.compile.c++ ../../../bin.v2/libs/math/tools/clang-darwin-12.0/debug/link-static/threading-multi/visibility-hidden/hyp_1f1_data.o

Are you on a case-insensitive file system?

[jzmaddock]

Yes. But the CI system should really have spotted that :(

Will fix shortly.
