Can I see your code? It builds? sample.so is in the build dir?

[biter777]

Of course. See below... On pg10 no problem, but on pg11 it swears at the absence of a .bc file. And if I install the extension myself on pg11, it works.

On the 'build' dir I have: Makefile sample.control sample.h sample.so sample--0.1.sql

Code:

package main

import (
    "github.com/microo8/plgo"
)

func MakeTsVectorTrigger(td *plgo.TriggerData) *plgo.TriggerRow {
    return td.NewRow
}

same problem

It looks like it is related to the new JIT in postgresql: https://www.postgresql.org/docs/current/jit-extensibility.html

Same problem here.

I faced a similar issue in other extensions and make install with_llvm=no worked.

It works. But... There should be a llvm .bc producer also.

[microo8]

Can someone please take a look at it? I don't know even where to start and also I can't reproduce it.

[mochizk]

I think you can reproduce this by configuring postgresql with ./configure --with-llvm to enable JIT. In that case Makefile try to generate llvm bit code files(.bc), but cannot generate it from Go code.

In src/makefiles/pgxs.mk, with_llvm variable is used to control this behavior. So I use make install with_llvm=no, but I'm not sure this is correct solution.

install simple: postgresql-11-postgis-2.5, postgresql-server-dev-11. under ubuntu 18.04.

Yesterday i found some sources, but it's too hard for me at this moment.

Any news on the subject? p.s. Maybe it's easy to make a copy of the compiled extension without the bc file?

[microo8]

Just use make install with_llvm=no
