Description:

After the release 7.0.17 I cant build this release because on compilation time it cant find any reference to isfinite:

I tried to build against a pristine vm to see if any package that we use created this problem but on a fresh vm the problem persists

I think that this problem is related to commit https://github.com/php/php-src/commit/714d825b62e719447686da6efe3b4063c2f25749

From AC_CHECK_DECLS documentation:

> Unlike the other ‘AC_CHECK_*S’ macros, when a symbol is not declared, HAVE_DECL_symbol is defined to ‘0’ instead of leaving HAVE_DECL_symbol undeclared.

Presumably that's the culprit, we're checking for definedness.

Can you please verify that https://github.com/php/php-src/commit/2e8308260513015dbf80ff0239eca79dbca4f36e does indeed resolve the build failure?

Hi,

unfortunately i had the same problem on the rpm build and on a different vm using ./configure ; make after applying the patch
 [2017-03-17 19:50 UTC] nikic@php.net
Did you run ./buildconf --force prior to running ./configure?
 [2017-03-17 20:48 UTC] 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 21:01 UTC] 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 22:27 UTC] 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

gcc version 4.1.2 ?? That compiler is over 10 years old. You are probably going to need to add -std=c99 to your build flags to get it to work on any modern codebase, or for heaven's sake, upgrade to a compiler from this decade.

gcc version 4.1.2 ?? That compiler is over 10 years old. You are probably going to need to add -std=c99 to your build flags to get it to work on any modern codebase, or for heaven's sake, upgrade to a compiler from this decade.
