problem with def of inet_ntop() in git-compat-util.h as well as other places

problem with def of inet_ntop() in git-compat-util.h as well as other places

[dev]

per :


  http://pubs.opengroup.org/onlinepubs/009695399/functions/inet_ntop.html


The last parameter is not unsigned long but socklen_t size.

This causes a problem on things like Solaris :

 * new build flags
    CC credential-store.o
"git-compat-util.h", line 516: error: identifier redeclared: inet_ntop
        current : function(int, pointer to const void, pointer to char,
unsigned long) returning pointer to const char
        previous: function(int, pointer to const void, pointer to char,
unsigned int) returning pointer to const char :
"/usr/include/arpa/inet.h", line 68
cc: acomp failed for credential-store.c
gmake: *** [credential-store.o] Error 2



Therefore I hacked around it with a #ifdef __SunOS_5_10 for the sake of
getting the build done.


However ran into a problem, again, with compat/inet_ntop.c which seems
to be not needed at all since inet_ntop() handles both IPv6 and IPv4
just fine.   Really I don't see why this file gets carted around so much
as it is even in the Apache svn codebase as well.

Not needed.

Therefore I commented out the inet_ntop() function entirely therein.

Also the Makefile's generated are all borked full of GCCism "CFLAGS = -g
-O2 -Wall"  which means very little on some OS wherein the gcc compiler
is not the default.  Love GCC. I bootstrap it all the time. However this
is Solaris and am using ORacle Studio 12.3 compilers and therefore the
CFLAGS in the Makefiles are just silly.  Lastly, the linkage to libintl
should look in /usr/local/lib if the LD_LIBRARY_PATH and other env vars
are setup correctly. However the Makefile's seem to miss this fact and
-lintl needs to be manually hacked into place.

Still doesn't "just build" yet.  Getting there :-\

That declaration should only be used if you have NO_INET_NTOP defined by
the Makefile. That is not defined by default for Solaris. Have you
specified it yourself, or are you using the autoconf script? If the
latter, I suspect its test for inet_ntop needs to be fixed.

Again, that should not be compiled at all unless you have NO_INET_NTOP
set. Fixing that should solve both of your problems.

Yes, this is a potential portability problem we've discussed before, but
literally nobody has ever complained. I suspect it's a combination of
many compilers accepting those arguments (e.g., clang is fine with it)
and people on exotic compilers accepting that "make CFLAGS=" is a
reasonable starting point (you can also put "CFLAGS = " into your
config.mak if you do not want to remember to include it on each make
invocation).

I do not usually see Makefiles peeking at LD_LIBRARY_PATH, which is for
runtime resolution. Do you need to set LDFLAGS in your environment (or
in config.mak)?

Good day gentlemen. With coffee in hand I am taking a crack and getting
git to compile out of the sources neatly and therefore I have hit a
few bumps.  Inline comments below :

wow.

OKay, in that case there seems to be another problem which, as you say,
would fix a few things in one shot. So we have inet_ntop() in the basic
socket function libs in Solaris for sure so we should not see
NO_INET_NTOP
defined.  But we are.  :-\

I am going to extract the tarball once again and start fresh.

Then I see in some Makefile's :

$ find . -type f -name Makefile | xargs grep "^CFLAGS" | cut -f2 -d\:
CFLAGS = -g -O2 -Wall
CFLAGS = -g -O2 -Wall
CFLAGS = -g -O2 -Wall
CFLAGS = -g -O2 -Wall
CFLAGS = -O2 -Wall
$


So CFLAGS is ignored entirely.


Also in the Makefile at the top level I see :


ifdef NO_INET_NTOP
        LIB_OBJS += compat/inet_ntop.o
        BASIC_CFLAGS += -DNO_INET_NTOP
endif
ifdef NO_INET_PTON
        LIB_OBJS += compat/inet_pton.o
        BASIC_CFLAGS += -DNO_INET_PTON
endif


No reason for either of those to be defined, but I bet that you are
right
and they are ... and should not be.

A config.mak file eh ?

I must look for that.

Yep, you're right of course. You can see I have no LDFLAGS defined.
Guess
I need that.

Anyways, thanks for the input. I would love to see this "just build" and
with a few more emails and some tinkering it should right?

Note that git's Makefile will not read CFLAGS from the environment (you
have to give it to make on the command-line, or put it in config.mak).
However, running "./configure" with that in the environment should put
the result into config.mak.autogen.

I have never seen LD_OPTIONS before. The usual variable for this is
LDFLAGS, and note that it is handled in the environment the same way as
CFLAGS above.

Well, that's likely the source of some of your problems. The config.log
can probably tell you more about why the check does not find inet_ntop.

No, it's not. The Makefiles are not generated by autoconf, because
autoconf is not required to build git (most of us do not use it at all).
Instead, the static Makefile includes config.mak.autogen, which is
generated by autoconf when you run "./configure" (and which overrides
the default in the Makefile). Try grepping for CFLAGS in that file.

I think they are defined by your config.mak.autogen, based on the output
you showed above.

I do not see anything that drastic that needs changed. Building
_without_ running ./configure might even just work (it has sane defaults
for many operating systems), though you would need to pass along the
bits from your environment, like:

  make CFLAGS="$CFLAGS" LDFLAGS="$LD_OPTIONS"

You would potentially also need to turn off a few feature flags manually
(e.g., NO_EXPAT, NO_GETTEXT). There's a complete list at the top of the
Makefile. The configure script can usually figure these out for you, but
the static Makefile does not.

Well I have heard now a few times of this config.mak file and when I
extract the source tarball I see :

$ ls -lap config*
-rw-r--r--   1 dclarke  adbs       44502 Jul 30 22:10 config.c
-rw-r--r--   1 dclarke  adbs         540 Jul 30 22:10 config.mak.in

So I guess I have to create a config.mak file from somewhere.

>From the INSTALL file I see that most of these variables are in the
pre-written and supposedly ready to run Makefile.  OKay.  I think I
had better crack that open and see what I need to change in there.
Most likely CFLAGS and a way to locate OpenSSL libs etc but who knows.

The problem is that this is not Linux and not GNU ld and therefore :

http://docs.oracle.com/cd/E19253-01/817-1984/6mhm7pl1l/index.html

So if I want to ensure that things like ELF headers contain the correct
stuff to locate libraries ( never ever use LD_LIBRARY_PATH as it is
the kiss of death ) then I need things like LD_OPTIONS and others.

So I will work through this from the Makefile provided and see if I
can get the CFLAGS that I want as well as other env vars.

I should try that on Solaris once to see what happens.  Make popcorn.

Instant fail.

Let's try GNU make :

$ gmake
GIT_VERSION = 2.0.4
    * new build flags
    CC credential-store.o
cc: -W option with unknown program all
gmake: *** [credential-store.o] Error 1

More instant fail.

Sounds good ... let's see :

gmake CFLAGS="$CFLAGS" LDFLAGS="$LD_OPTIONS"
.

So this is not Linux and so a pile of fiddling is required. Welcome to
the world of Oracle Solaris where nothing from the Linux world ever
"just works".  It looks like somewhere along the line the idea of
linking
with -liconv or perhaps -lintl was lost.  Not sure yet.

For now I want to keep chugging along to see if I can get a default
no-hack
build and then go back and start over with things in the Makefile to see
if I can get the whole process to make the binaries that I want with
the required bits in the ELF headers and correctly NEEDed libs etc.

Sorry, let's take a step back.

What exact commands do you use to build, starting from a pristine
extracted tarball?  What output do you get back?

Sounds like NEEDS_LIBICONV should be set on Solaris.  You can test
this by passing NEEDS_LIBICONV=YesPlease on the gmake command line and
seeing what happens.

But it seems odd --- was iconv once part of libc on Solaris and then
moved out or something?  There have been lots of people building git
on Solaris over the years (and writing patches to fix other build
problems) without needing to set that flag.

The options for tweaking the build are described at the top of the
Makefile.

That looks to be the ticket to a binary.

Entire build completes with piles of warnings but I get a git binary :

Great, a problem with some libz.so.1 that we don't even need since we
have libz in /usr/local/lib just fine.  I have to look into that.

Funny I don't see libcurl anywhere. Thought that was needed? Also the
RUNPATH
and RPATH look duplicated and slightly borked but the initial data there
is correct enough to locate all the libs except for some strange libz
issue.

What I need to do now is run some tests. Really I should keep going
to get linkage with libssh2 and libcurl as well as correct perl in
the /usr/local/bin directory. I'll have to keep tweaking with the
various magic on the "gmake" command I guess.

There are plenty of dependencies and therefore I have GNU libiconv thus
:

/usr/local/bin/iconv

Well I see what I see and am extracting from a tarball and reporting
precisely what is happening. Traditionally git has been a nightmare
to build on anything but linux. That is just my experience.  Let's
not even talk about OpenBSD.  A real nightmare.

The main git binary is not linked with libcurl, only the HTTP and FTP
programs.  You'd want to check git-remote-http, for instance.

Actually I think we have some real progress to report here.  After
scanning through the various magic incantations in the Makefile and
some trial and error I arrived at this gem :

Ignore the misleading libz issue.  I really don't think it is a
problem however I may dig into it. That is libz.so.1 which is needed
by libcrypto.so.1.0.0 from OpenSSL 1.0.1i and I just don't see
an issue given that OpenSSL 1.0.1i passes all its tests.

I did run a few clone tests :

So that looks pretty good thus far.

I must say thank you for the guidance.  All I need to do now is figure
out a way to run a test over SSH with a dummy repo of some sort.

Re: problem with def of inet_ntop() in git-compat-util.h as well as other places

Why is NO_INET_NTOP set?  What commands are you using to build?  If
you are using autoconf, what does your config.mak.autogen say?

Puzzled,
