[llvm-dev] [RFC] Adding a char set converter to Support library

[Eli Friedman via llvm-dev]

iconv is a POSIX API; the license of any particular implementation shouldn't matter.

I'd be more concerned that the set of encodings supported by any particular implementation of iconv isn't portable.  I'd like to avoid adding host-specific behavior here; ideally, the list of supported encodings should be hardcoded into LLVM, and we should support all of those encodings on every host.

My understanding is that dynamically linking should pose no problem, but I
am no lawyer. On Linux, glibc is also under LGPL license, and LLVM usually
links against it.
(There is really no need for us to depend on libiconv. If it is deemed to
risky, then I can dropped it.)

As far as I remember, libiconv is under LGPL. Will this cause any
troubles?
