Summary: Cross-compiling not supported
Status: Open
Type: Bug
Package: opcache
Operating System: Linux
PHP Version: 5.5.6
Block user comment: N
Private report: N
New Comment:
all of these cross-compilation problems could easily be solved if php would use the cache variables
feature for these variables as well so user can easily override the test from the commandline.
example:
./configure ac_cv_crypt_SHA512=yes ac_cv_linux_lock=yes
however due to lack of it, you need to either patch the configure script, or the configure.ac and
rerun all the autoreconf stuff which is highly error prone due to all the involved m4 macros and
different tool versions.
note that the cache variable is used for the above SHA512 crypt check
$as_echo_n "checking for SHA512 crypt... " >&6; }
if ${ac_cv_crypt_sha512+:} false; then :
$as_echo_n "(cached) " >&6
else
if test "$cross_compiling" = yes; then :
ac_cv_crypt_sha512=no
else
cat confdefs.h - <<_ACEOF >conftest.$ac_ext
but not for this check, the one for strcasestr and probably others.
for comparison:
{ $as_echo "$as_me:${as_lineno-$LINENO}: checking for strcasestr" >&5
$as_echo_n "checking for strcasestr... " >&6; }
if test "$cross_compiling" = yes; then :
{ { $as_echo "$as_me:${as_lineno-$LINENO}: error: in \`$ac_pwd':" >&5
$as_echo "$as_me: error: in \`$ac_pwd':" >&2;}
as_fn_error $? "cannot run test program while cross compiling
See \`config.log' for more details" "$LINENO" 5; }
else
cat confdefs.h - <<_ACEOF >conftest.$ac_ext

Fails with PHP 7.0.2/OpenWRT as well, and disabling opcache isn't an acceptable option as the
enhanced opcache performance is a major reason to want PHP 7.
Obviously the test program can't be run in a cross-compile - the configure script should be
modified to take flock_type as an input variable to support cross-compiling. If the input variable
is set then don't bother with the test program.

"checking "whether flock struct is linux ordered"... "no"
checking "whether flock struct is BSD ordered"... "no"
configure: error: Don't know how to define struct flock on this system, set
--enable-opcache=no"
I had the same error, while compiling PHP (5.6.4, but that does not matter, because I tried als PHP
5.6.3 and was reproducable) on Debian GNU/Linux. I saw that problem when I forgot to set
LD_LIBRARY_PATH environment variable.
So doing it like that solved my problem:
$ export LD_LIBRARY_PATH=/usr/local/mysql/lib
$ ./configure --enable-fpm --with-mcrypt --with-zlib --with-curl --disable-debug --disable-rpath
--enable-inline-optimization --with-bz2 --enable-sockets --enable-zip --with-fpm-user=www-data
--with-fpm-group=www-data --with-mysql=/usr/local/mysql/
$ make
$ make test
# export LD_LIBRARY_PATH=/usr/local/mysql/lib
# make install

Same problem.
In ZendAccelerator.h it looks for the presence of other defines such as __linux__ first to determine
flock order, in favor of the results of the test (HAVE_FLOCK_LINUX)
So why is not being able to run the test fatal?

Cross-compiling not supported
I'm trying to cross-compile PHP 5.5.6 with OpenWRT buildroot. If I disable OPcache, everything
goes well.
with OPcache enabled, configure hangs with this error.
