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 ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
