extern "C" {
and the closing counterpart by BEGIN_C_DECLS and END_C_DECLS.
Notable exceptions are:
- opal/include/opal_config_bottom.h:
This is our generated code, that itself defines BEGIN_C_DECL and
END_C_DECL
- ompi/mpi/cxx/mpicxx.h:
Here we do not include opal_config_bottom.h:
- Belongs to external code:
opal/mca/backtrace/darwin/MoreBacktrace/MoreDebugging/MoreBacktrace.c
opal/mca/backtrace/darwin/MoreBacktrace/MoreDebugging/MoreBacktrace.h
- opal/include/opal/prefetch.h:
Has C++ specific macros that are protected:
- Had #if ... } #endif _and_ END_C_DECLS (aka end up with 2x
END_C_DECLS)
ompi/mca/btl/openib/btl_openib.h
- opal/event/event.h has #ifdef __cplusplus as BEGIN_C_DECLS...
- opal/win32/ompi_process.h: had extern "C"\n {...
opal/win32/ompi_process.h: dito
- ompi/mca/btl/pcie/btl_pcie_lex.l: needed to add *_C_DECLS
ompi/mpi/f90/test/align_c.c: dito
- ompi/debuggers/msgq_interface.h: used #ifdef __cplusplus
- ompi/mpi/f90/xml/common-C.xsl: Amend
Tested on linux using --with-openib and --with-mx
