Bug #77471 [Asn->Opn]: configure: error: cannot run test program while cross compiling

Edit report at https://bugs.php.net/bug.php?id=77471&edit=1 ID: 77471 Updated by: petk@php.net Reported by: stephane at qnap dot com Summary: configure: error: cannot run test program while cross compiling -Status: Assigned +Status: Open Type: Bug Package: *Compile Issues Operating System: ubuntu 1404 PHP Version: 7.2.14 -Assigned To: petk +Assigned To: Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2019-01-16 19:09:15] petk@php.net Patching 7.2 with these issues might be simplest done to only fill the sensible defaults for the last argument of the AC_TRY_RUN macro [1]. Now there are some blank last arguments used in some places. The AC_TRY_RUN macro is an obsolete macro of the same functionality as its new version AC_RUN_IFELSE (which is used in 7.3). So basically even the migration to newer macro can be done for PHP 7.2 but simplest is probably to go manually through the AC_TRY_RUN occurrences and fill in the sensible defaults for the last argument. Last argument means what happens when cross compiling. End system can't be just run at this case because we are using one system to compile for another system where program can run differently... I'll check if I can come up with some patch in some decent time here, otherwise send the pull request to go from there if possible, please.

We can backport this change, or at least the part pertaining to strcasestr. ------------------------------------------------------------------------ [2019-01-16 15:44:06] stephane at qnap dot com Description: ------------ trying to cross compile PHP 7.2.14 autoconf is stuck on checking for FlatFile support... builtin checking whether to enable DBA interface... yes, shared checking whether to enable DOM support... yes checking for xml2-config path...
