Bug 1352312

Works fine for me, for example in the prepared bash-completion development dir. Need (much) more details and exact reproducer to be able to say more.

I am using PostgreSQL source directory

[pavel@nemesis postgresql]$ pwd
/home/pavel/src/postgresql
[pavel@nemesis postgresql]$ ls 
aclocal.m4  config.log     configure     contrib    doc          GNUmakefile     HISTORY   README      src
config      config.status  configure.in  COPYRIGHT  finitdb_log  GNUmakefile.in  Makefile  README.git  tmp_install
[pavel@nemesis postgresql]$ make 
config.status  GNUmakefile    src/           
[pavel@nemesis postgresql]$ make 


expected: all check install installdirs installcheck installcheck-parallel ...

I tested another source - bash - and it doesn't work too.

My installation is fresh Fedora 24.

Works for me on F24 and prepared bash source dir. For some reason producing the completions takes a long time the first time, but the expected ones eventually appear, and it's quick afterwards.

Still need more info, see Troubleshooting in bash-completion's README.md, and post the generated output somewhere for examination.

trace log for auto complete in PostgreSQL src directory

I found some example of using  _make_target_extract_script

It doesn't work on my comp

sed -nrf <(_make_target_extract_script --) Makefile

sed -nrf <(_make_target_extract_script --) Makefile
+ sed -nrf /dev/fd/63 Makefile
_make_target_extract_script --
++ _make_target_extract_script --
++ local mode=--
++ shift
++ local prefix=
+++ command sed 's/[][\,.*^$(){}?+|/]/\\&/g'
+++ sed 's/[][\,.*^$(){}?+|/]/\\&/g'
++ local prefix_pat=
++ local basename=
++ local dirname_len=0
++ [[ -- == -d ]]
++ local 'output=\1\2'
++ cat
++ [[ -z '' ]]
++ cat
sed: file /dev/fd/63 line 22: invalid reference \2 on `s' command's RHS

That's most likely because of the "r" in -nrf. I don't know where you got it, we don't call "sed -nrf" but "sed -nf".

(I haven't looked at your trace yet.)

It returns nothing

Reproduced with the PostgreSQL build dir also on F-23, moving discussion to upstream at https://github.com/scop/bash-completion/issues/53

Closing as WONTFIX per upstream resolution wrt PostgreSQL dir. If you find other Makefiles for which completion doesn't work, feel free to file new bugs (preferably upstream), one per case.
