There is no rule for building the target “sample.bc” required for “all”. Stop about plgo HOT 12 CLOSED

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

from plgo.

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

from plgo.

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
}

from plgo.

It looks like it is related to the new JIT in postgresql:

Same problem here.

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

from plgo.

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

from plgo.

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.

from plgo.

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.

from plgo.

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

from plgo.

Just use make install with_llvm=no

from plgo.
