[ Please pardon the pedantic long winded email. I got carried away. ]
Also, if you are a standards(5) compliant focused person then you may want
to watch for _POSIX_SOURCE. From the "POSIX Programmers Guide, Writing
Portable UNIX Programs", Donald Lewine, page 25 we see :
/* Feature test switches */
This section should define the _POSIX_SOURCE macro to enable
the POSIX symbols and disable all unspecified symbols.
That can have some pretty wide sweeping effects on how a binary is
compiled and linked.
Also, in standards(5) we see mention of various OpenGroup documents and
specs that Solaris revs from 2.5.1 through 10 are compliant with. There is
no mention of OpenSolaris or Solaris Nevada so therefore I do not know
where either of those stand.
Should one wish some degree of compliance with SUSv3 then there is a PATH
to set :
From standards(5) in OpenSolaris snv_111b
POSIX.1-2001, SUSv3
1. /usr/xpg6/bin
2. /usr/xpg4/bin
3. /usr/ccs/bin
4. /usr/bin
5. directory containing binaries for your compiler
6. other directories containing binaries needed by
the application
I do not know what degree of compliance there is in OpenSolaris snv_111b
but my PATH and env looks like so when I compile things :
# env | sort
EDITOR=/usr/xpg4/bin/vi
HOME=/export/home/dclarke
HZ=
LANG=C
LC_ALL=C
LC_MESSAGES=en_US.UTF-8
LOGNAME=dclarke
MAIL=/var/mail/dclarke
MANPATH=/usr/share/man:/usr/X11/share/man
OLDPWD=/opt
PAGER=/usr/xpg4/bin/more
PATH=/usr/xpg6/bin:/usr/xpg4/bin:/usr/ccs/bin:/usr/bin:/opt/SUNWspro/bin:/usr/sbin:/bin:/sbin:/usr/X11/bin:/usr/dt/bin:/usr/openwin/bin:/opt/schily/bin:/opt/csw/bin
PWD=/export/home/dclarke/build
SHELL=/bin/ksh93
SHLVL=1
TERM=xterm
VISUAL=/usr/xpg4/bin/vi
_=/usr/xpg4/bin/env
To be honest, I know that there are a bucket load of #define's in
<unistd.h> and also in the implementation specific <sys/unistd.h> that
speak to various specs and standards that one may comply with. If one is
careful you can end up with code that compiles *everywhere* and runs
exactly as expected on all systems that are compliant with a SUSv3 spec or
_XPG6.
I do know that a default install of OpenSolaris from media will fail to
compile a simple hello.c because there are no SUNWhea headers provided :
$ uname -a
SunOS aequitas 5.11 snv_111b i86pc i386 i86pc

Well what can you now dig out of that binary ? I mean information about
how it was built and what tools were used ?
$ elfdump hello | grep NEED
[0] NEEDED 0x165 libc.so.1
[1] NEEDED 0x18b libdl.so.1
[17] VERNEED 0x80507f4
[18] VERNEEDNUM 0x1
That tells you what shared objects are needed.
$ elfdump hello | grep PATH
[4] RUNPATH 0x196 /usr/xpg4/lib
[5] RPATH 0x196 /usr/xpg4/lib
That tells you where the runtime linker is going to look for those needed
libs. If not found there then it will default to /usr/lib and you can play
with LD_FLAGS/LD_OPTIONS to see more details on that.
You can set this in your environment :
LD_OPTIONS=\-R/somepath/lib/\ \-L/somepage/lib
export LD_OPTIONS
Studio will stuff that RUNPATH/RPATH data into the resultant binary and
now the runtime linker will look in that path first for libs. That can be
dangerous and can result in a real security breach if someone gives you a
binary with their own custom libs that they hacked. Even more scary is
something call $ORIGIN for a place to look for runtime dynamic libs. Feel
free to look into it with Daryl Gove's book "Solaris Application
Programming" and please see
http://www.blastwave.org/dclarke/blog/?q=node/138
Some information about the tools used can be found with :

whoops !
I should set the compiler flag -Qy such that information is placed in
there.
If you really want to look into the ELF Header format there are a bucket
load of flags but one thing will jump out at you and that is the ei_class
and e_machine data :
$ elfdump hello | head -12
ELF Header
ei_magic: { 0x7f, E, L, F }
ei_class: ELFCLASS32 ei_data: ELFDATA2LSB
e_machine: EM_386 e_version: EV_CURRENT

e_flags: 0

e_shoff: 0x17d4 e_shentsize: 40 e_shnum: 32

Well we get a funky list of %foobar% stuff and also we know the assembler,
the linker and the compiler was all Sun Studio 12.
You won't get information like that from GCC.
You can get a recent GCC thus ( as root ):
# pkgadd -d http://blastwave.network.com/csw/pkgutil_`/sbin/uname -p`.pkg
# rm /opt/csw/etc/pkgutil.conf
# /bin/printf "progress=dot:mega\n" > $HOME/.wgetrc

Just hit enter and watch. You may get asked a question or two, hit "y" and

At the end run the mkheaders script that comes with GCC :
# /opt/csw/gcc4/libexec/gcc/i386-pc-solaris2.10/4.3.4/install-tools/mkheaders
What you get is a 64-bit aware GCC 4.3.4 but despite all the manhours that
went into giving you that package it won't hold a candle to Studio 12. It
just won't. Sorry.
Try to compile that same hello.c and then go looking for information about

SunOS aequitas 5.11 snv_111b i86pc i386 i86pc
Also try this just to see the effect :
$ LD_OPTIONS=\-R\$HOME/lib/\ \-L\$HOME/lib
$ export LD_OPTIONS
$ gcc -m32 -std=c89 -D_TS_ERRNO -D_POSIX_SOURCE -o hello_i386 hello.c
$ elfdump hello_i386 | grep PATH
[3] RUNPATH 0x20c $HOME/lib/
[4] RPATH 0x20c $HOME/lib/
I don't want to get into a gcc versus Studio thread but there is a pile of
information available to the user via a few tools. The best is Daryl
Gove's book.
