Edit report at https://bugs.php.net/bug.php?id=74265&edit=1 ID: 74265 Updated by: kaplan@php.net Reported by: deferraz at terra dot com dot br Summary: Build problems after 7.0.17 release: undefined reference to `isfinite' -Status: Assigned +Status: Closed Type: Bug Package: Compile Failure Operating System: CentOS-5 PHP Version: 7.0.17 Assigned To: nikic Block user comment: N Private report: N New Comment: I had the problem with PHP 7.1.3 on AIX, and the patch fixed it. thanks. Previous Comments: ------------------------------------------------------------------------ [2017-03-17 22:27:29] deferraz at terra dot com dot br I think i found the problem on the rpm build server: In the new pristine server i had installed autoconf-2.59-12 m4-1.4.5-3 , and in the rpm build server i had installed autoconf-2.65 and m4-1.4.13, for that reason , on CentOS 5 that chack for isfinite function using autoconf2.65 that test doesnt fail and with autoconf-2.59 it fails (Right now I can't say why). Using the distribution vanilla packages of autoconf/m4 that isfinite test fails and the patch that you sent builds successfully. I am including this information on this bug report so anyone with the same problem can fix the situation Thanks for the quick patch response and information about this issue ------------------------------------------------------------------------ [2017-03-17 21:01:31] deferraz at terra dot com dot br I think that i found the possible issue, on the vanilla build the config.log says that isfinite is not found, and my other build server that i do my rpm builds finds the function: Upstream config.log snippet: configure:131360: $? = 0 configure:131362: ./conftest configure:131365: $? = 0 configure:131384: result: no configure:131398: checking whether isfinite is declared configure:131423: cc -c -I/usr/include -g -O2 -fvisibility=hidden conftest.c >&5 conftest.c: In function 'main': conftest.c:383: error: 'isfinite' undeclared (first use in this function) conftest.c:383: error: (Each undeclared identifier is reported only once conftest.c:383: error: for each function it appears in.) configure:131429: $? = 1 My rpm build server: configure:95014: checking whether isfinite is declared configure:95014: cc -c -I/usr/include -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m64 -mtune=generic -fno-strict-aliasing -Wno-pointer-sign -fvisibility=hidden conftest.c >&5 configure:95014: $? = 0 configure:95014: result: yes The funny thing on this situation that for what I understand those functions are related to math.h and math library that I use the original ones from CentOS distro ------------------------------------------------------------------------ [2017-03-17 20:48:49] deferraz at terra dot com dot br Indeed, the buildconf --force solved the problem , but i only got a successfull build against the upstream source without any patches , on my rpm spec build the problem persisted and the buildconf --force executes for every build. There is something that I can analyze to catch the possible problem on my rpm build? The patch had applied and buildconf executes without problem, right now I am without any clues Thanks in advance ------------------------------------------------------------------------ [2017-03-17 19:50:50] nikic@php.net Did you run ./buildconf --force prior to running ./configure? ------------------------------------------------------------------------ [2017-03-17 19:34:16] deferraz at terra dot com dot br Hi, unfortunately i had the same problem on the rpm build and on a different vm using ./configure ; make after applying the patch ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
