Build-time failure: g++9 / FreeBSD-12
jkeenan opened this issue · comments
Today I had occasion to try to install a CPAN library (Devel-NYTProf) on FreeBSD-12 using g++-9.3.0 as the C-compiler with which the associated perl was compiled. Similar attempts on this machine with clang10 and gcc9 were successful. But with g++-9 I got:

*** Error code 1
Stop.

Can you investigate?
Thank you very much.

error: invalid conversion from 'void*' to 'HEK*'
because of a C++ compiler. This might need a #ifdef'ed _cplusplus
AFAIK perl was not C++ safe at all, only the linker is commonly g++. Will check.
Confirmed.
