Hello.
I try to compile a package of C++ software for FreeBSD with CLANG which
uses clang++. I have to use -stdlib=3Dlibc++ -std=3Dc++11.
I receive the following error and after consulting developers of the
code I was informed that libc++ routine "std::isinf()" should return
boolvec_t, but it returns obviously int.
Well, I'm not an expert, I take this for true and I'm inclinded to ask
here whether there is a bug I discover in the code I'm supposed to
compile or whether this is a bug in the FreeBSD's libc++ implementation
used.
The fault is as follows:
[...]
/usr/bin/clang++ -Xclang -ffake-address-space-map -std=3Dc++11
-fno-exceptions -emit-llvm -ffp-contract=3Doff -stdlib=3Dlibc++ -c -target
