- Log ----------------------------------------------------------------- commit 0879cd66ef3f00918ae26d9bb7ac555d3911c548 Author: Jarkko Hietaniemi <[email protected]> Date: Fri Sep 30 17:18:16 2016 -0400 PL_inf/PL_nan need different export with C++ After the 9ee3aea9, the old way worked with C++ for building the core, but then failed building the POSIX extension. (This change is about building with C++ after the 9ee3aea9, even though that change was about ordering perl.h into a more logical order for vax-netbsd, or for any non-IEEE-754 platform.) ----------------------------------------------------------------------- Summary of changes: perl.h | 7 +++++++ 1 file changed, 7 insertions(+) diff --git a/perl.h b/perl.h index 628315f..8444bc0 100644 --- a/perl.h +++ b/perl.h @@ -5719,11 +5719,18 @@ EXTCONST bool PL_valid_types_NV_set[]; /* In C99 we could use designated (named field) union initializers. * In C89 we need to initialize the member declared first. + * In C++ we need extern C initializers. * * With the U8_NV version you will want to have inner braces, * while with the NV_U8 use just the NV. */ + +#ifdef __cplusplus +#define INFNAN_U8_NV_DECL EXTERN_C const union { U8 u8[NVSIZE]; NV nv; } +#define INFNAN_NV_U8_DECL EXTERN_C const union { NV nv; U8 u8[NVSIZE]; } +#else #define INFNAN_U8_NV_DECL EXTCONST union { U8 u8[NVSIZE]; NV nv; } #define INFNAN_NV_U8_DECL EXTCONST union { NV nv; U8 u8[NVSIZE]; } +#endif /* if these never got defined, they need defaults */ #ifndef PERL_SET_CONTEXT -- Perl5 Master Repository
