Subject: Re: [PHP-DEV] Enabling opcache causes libraries to build as static

Morning David,

    To confirm it was something to do with opcache, I removed opcache from
the source tree:

    krakjoe@fiji:/usr/src/php-src$ ./configure --disable-all | grep static
    checking if cc static flag -static works... yes
    checking whether to build static libraries... yes

    That's pretty strange, it doesn't seem connected to opcache, at least
on my os (ubuntu).

    So I try this, still no opcache in tree:

    krakjoe@fiji:/usr/src/php-src$ ./configure --disable-all
--disable-static | grep static
    checking if cc static flag -static works... yes
    checking whether to build static libraries... yes

    So I dig around in configure ... and find this:

    enable_shared=yes
enable_static=yes

case $php_sapi_module in
  shared)
    enable_static=no
    case $with_pic in
      yes)
        standard_libtool_flag='-prefer-pic'
        ;;
      no)
        standard_libtool_flag='-prefer-non-pic'
        ;;
    esac
    EXTRA_LDFLAGS="$EXTRA_LDFLAGS -avoid-version -module"
    ;;
  *)
    standard_libtool_flag='-prefer-non-pic -static'
    if test -z "$PHP_MODULES" && test -z "$PHP_ZEND_EX"; then
      enable_shared=no
    fi
    ;;
esac

   Unconditionally setting enable_static here makes --enable-static be
ignored.

   Over to someone else who understands why this is the case ...

Cheers
Joe
