Using C++ With SPI?

[Clay Luther]

I had been having good luck writing stored procs in C++ with Postgres.
But, today, I needed to include the SPI interface to help a trigger
along, aka

#include "executor/spi.h"

and this is completely ungrokable by GNU C++.

Am I stuck, or can I solve this problem (tried extern "C" {}, no go).

Thanks.

You'll definitely need 'extern "C" {}' around that include.

Why don't you try that again and actually post an error message so
people can try and help you?

Pffft. I figured it was obvious.
#include "postgres.h "
#include "fmgr.h"
extern "C"
{
#include "executor/spi.h"
#include "commands/trigger.h"
};

int main(int argc, char* argv[])
{
return 0;
}
