Thread: Solaris install - "cannot compute sizeof (off_t)" error - readline issue?

I'm trying to install postgres 8.4.5 on Solaris 10 (Sun):
./configure --prefix=/app/postgres-8.4.5 \
--with-libs=/app/usr/local/lib \
--with-includes=/app/usr/local/include

(lib & include specified because I have readline installed in a
non-standard location.  Yay.)

This fails with this error:
checking size of off_t... configure: error: cannot compute sizeof (off_t)

The config.log contains this (I'm not sure how much to include here):
conftest.c:71: warning: left shift count >= width of type
conftest.c:71: warning: left shift count >= width of type
conftest.c:73: error: size of array `off_t_is_large' is negative

...and this interesting tidbit, which I just discovered:
ld.so.1: conftest: fatal: libreadline.so.5: open failed: No such file
or directory

Per alvherre's suggestion on irc, I tried this:
./configure --prefix=/app/postgres-8.4.5 \
--with-libs=/app/usr/local/lib \
--with-includes=/app/usr/local/include \
--disable-largefile

It failed with the same command-line error message as above.

config.log contains the same error about readline:
ld.so.1: conftest: fatal: libreadline.so.5: open failed: No such file
or directory

The only seemingly-relevant thing I found on google was this:
http://www.xinotes.org/notes/note/747/
I don't have the right privs on this server to try that solution, so I
tried running configure --without-readline JFK, and that was
successful.

But I really want readline.  ;)  Any ideas what the problem is?

Thanks!

First and foremost, I would highly recommend that you use the Sun
compiler to build it.  Jignesh Shah had (prior to his departure from
the once-great Sun Microsystems) written a couple of informative
articles that provided the most effective options to use depending on
your architecture.  Google his name and postgresql and I'm fairly
certain you'll get some good hits.  I believe he's working for VMware,
so if you're on an x86 system, he may have even more up-to-date
information building with the Sun compiler.

It's been many months since I've had to deal with compiling software
on Solaris, but IIRC I had to pass a few options in CFLAGS before
calling configure.  I also had a completely clean environment (i.e.
very minimal PATH, no LD_LIBRARY_PATH).  In the case of
LD_LIBRARY_PATH, check the output of crle to see if the admins have
added anything to the system runtime link path.

Try:
    CC=/your/path/to/suncc CFLAGS="-I/your/non-standard/include
-L/your/non-standard/lib -R/your/non-standard/lib ..." \
    ./configure ...

I got that error building on a unix platform that was missing some
library or another, the actual error had *nothing* to do with off_t,
rather, the off_t test module failed on this library load.

in fact it may have been readline.


here's what *I* used to compile on solaris x86 with readline...

first, I built this in my old account, in $HOME/src I untarred zlib
1.2.5, readline 6.1, and postgres 8.4.5

i compiled zlib and readline first, telling it to put the target in
$HOME as I only used the static link libraries to reduce dependencies
for my compiled postgres...   I specifically built readline and zlib as
static (.a) libraries only, not as shared (.so) libraries.

then, to compile postgres, I used this ./configure..

CC=/opt/SUNWspro/bin/cc CFLAGS="-xarch=amd64" ./configure
--prefix=/opt/pgsql-84 --with-libs=$HOME/lib \
      --with-includes=$HOME/include

and then ran gmake && gmake check && su "gmake install"

gmake is in /usr/sfw/bin ... I also had /usr/ccs/bin in my path but I'm
not sure this is important or not (ld is in there)

note, I'm using Sun Studio 11 (Sun cc 5.8) here.   Sun-err-Oracle Studio
12 works just fine, too.

This did the trick!  Thank you *very* much.

(Sorry for the delayed reply - I had to get the compiler installed on
this machine [it's not mine] and then I was at PgWest all last week.)
