[Bug libgcj/37019] [4.2 Regression] Inconsistent gcc-4.2.3/libjava/configure uses "grep" and "egrep" and "grep -E" and "$EGGREP" but not ggrep -- sed also is trouble

Would you click the "CONFIRMED" button please.

I need to build some dependencies (that will take a few days) before I can run
the _entire_ script, but I do have an initial report (see below) ...

Assume that _ALL_ commands (grep, make, egrep, diff, _everything_) are not
"valid" _GNU_ commands. 

The creator of the Operating System can name any command any name they want
(EG: Ralph can be spelled Ralf or Rolf etc). Similarly grep can be called sed
and sed can be called diff -- I'm not suggested that is a good idea, just that
it is possible.


>From a practical point of view it makes sense to run the command with
"--version" (or "-v" or "-V") and check that it is indeed a GNU program and
that the version is "new enough" that _ALL_ following uses of the command will
operate correctly.

Yes, that would be a rewrite of a lot of scripts but if you want to make sure
that everything works you need the sanity tests to run at the beginning of each
script. If you don't check that you are sane then how can you decide anything ?

The Solaris 11 OS that I am using is only a couple of months old.

When I do a directory listing to find my "g-prefixed" commands I get a list
like this (I edited out some obvious commands that are not "g-prefixed"
versions and hopefully was not too heavy-handed):

# ls -l /usr/bin/g*
-r-xr-xr-x   1 root     bin        30432 Jun 26 18:26 /usr/bin/gcmp
...
-r-xr-xr-x   1 root     bin       151740 Jun 26 18:26 /usr/bin/gdiff
-r-xr-xr-x   1 root     bin        36712 Jun 26 18:26 /usr/bin/gdiff3
...
-r-xr-xr-x   3 root     bin       116268 Jun 26 17:02 /usr/bin/gegrep
...
-r-xr-xr-x   3 root     bin       116268 Jun 26 17:02 /usr/bin/gfgrep
-r-xr-xr-x   1 root     bin        23568 Jun 26 19:58 /usr/bin/ggettext
-r-xr-xr-x   3 root     bin       116268 Jun 26 17:02 /usr/bin/ggrep
...
-r-xr-xr-x   1 root     bin       151780 Jun 26 18:00 /usr/bin/gm4
-r-xr-xr-x   1 root     bin       153036 Jun 26 18:01 /usr/bin/gmake
...
-r-xr-xr-x   1 root     bin       315084 Jun 26 19:58 /usr/bin/gmsgfmt
...
-r-xr-xr-x   1 root     bin        88376 Jun 26 16:48 /usr/bin/gpatch
...
-r-xr-xr-x   1 root     bin        34728 Jun 26 18:26 /usr/bin/gsdiff
...
-r-xr-xr-x   1 root     bin       312884 Jun 26 17:02 /usr/bin/gtar


That is about all I can spot from eye / memory / knowledge about GNUisms.


That list is, again: gcmp, gdiff, gdiff3, gegrep, gfgrep, ggettext, ggrep, gm4,
gmake, gmsgfmt, gpatch, gsdiff, gtar, (etc, possibly I missed one).

This means that any attempt to use these programs (on Solaris and _some_ other
OSes) will fail.


Here is the output for each program and for Solaris 11's "g-prefixed" version:

--------------------


To answer your question "Can you please specify for which grep and sed commands
you see errors?" here is an attempt to comply (until I finish the dependencies
(_if_ they can be built on this platform)) I can't finsh running the script
(and will have to remove the "qt" options I am configuring with).


Here is a comparison of the i386-pc-solaris2.11/libjava/config.log files with
the origonal "configure" and my modified "configure" where I added "g-prefixes"
everywhere I could see it was necessary. To shorten the list I edited the
output by hand:

# gdiff -Naur config_Origonal_configure.log config_Modified-1_configure.log
(Enclosed as an attachment in next message)

You can see how serious this is. The configury is getting a one-off error in
uname, doesn't know the "Invocation command line", reads the wrong specs file,
checks "gcc -v" instead of "xgcc -v", the list goes on and on ...

Basically the first few mistakes compound the rest and even _IF_ a later grep
command _could_ work (command is compatable with both (Solaris) grep and (GNU)
ggrep) it has little chance if it is fed incorrect information.


(See attachment in next message).

Thanks for looking at this Ralf.

YT,
Rob
