Description:
------------
Two notes; I have tried this on two separate Solaris 10 machines and I get this exact same error on both.  On both machines, past versions of PHP have successfully compiled -- namely PHP 5.1.6 and a few earlier ones as well.

Not doing anything particularly special here other than a 64 bit build (we use a large memory application with this) WHICH worked perfectly fine with 5.1.6...  The flags to build 64 bit are in CFLAGS and LDFLAGS, namely -mcpu=ultrasparc -m64 here's what happens:

./configure --prefix=/usr/local/64 --enable-sysvmsg --enable-sysvsem --enable-sysvshm --enable-sockets --with-pgsql=/usr/local/64/pgsql --with-pdo-pgsql=/usr/local/64/pgsql --with-libxml-dir=/usr/local/64 --enable-ftp --without-iconv
loading cache ./config.cache
checking for Cygwin environment... no
checking for mingw32 environment... no
checking for egrep... egrep
checking for a sed that does not truncate output... /usr/local/bin/sed
expr: syntax error
./configure: test: argument expected


'expr' shows up only about 60 billion times in the file, and I have been unable to reasonably isolate which one is actually failing.  Too bad shell scripts aren't nice enough to provide a line number! :)  I'm hoping someone can help me out here, and appologies if this has already been reported -- I did search the bug DB for quite awhile before posting :)


Thanks!

I had the some problem on OS X upgrading to 5.2, you just need to upgrade your shell (e.g., bash).
 [2006-12-15 04:52 UTC] cheetah at tanabi dot org
Okay; I upgraded the bash on the system and made sure configure was using it (it was using /bin/sh, which is Sun's 'sh' and therefore could be problematic).  Bash is now at 3.2 and now when I run configure (same command as mentioned in the original bug):

====

Then it continues on normally.  This problem looks like another problem I saw in the bug system, so I'll take a look around again for it.  The build was successful, so I'm inclined to not really care as much anymore :)  But if it's a real problem I'd like to help track it down all the same.

What kind of Bash are you using? What is the version #?

I had similar problem with php5.2.3 and php4.4.7. I was building php for my horde package and the following was observed when running configure(Sun Sparc Solaris 2.9):
# ./configure --prefix=/usr/local/php.5.23 
> --with-apxs=/usr/apache2/bin/apxs \
>   
> >> --with-gettext --with-dom \

I used gnu sed when I had the problem when using the Solairs sed.

Passing -- to mark the end of flags for expr doesn't work everywhere.

the expr info page suggests the expr tests in configure should be 
quoted with a leading space to avoid being interpreted as flags and 
remain as portable as possible:

I encountered this problem on Solaris 10 x86 as well. My path specified /usr/ucb before /usr/bin. Apparently the version of expr in /usr/ucb is not compatible with PHP's configure script. Simply removing /usr/ucb from my path fixed the problem.

Same syntax error with expr coming with BusyBox v1.24.2 (2016-06-23 08:49:16 GMT) multi-call binary.
