Python build goes into infinite loop

When I try to create Python 2.7.3 on Snow Leopard, it seems that the Make process is stuck in an endless loop. It looks like the configure script is being called over and over again, which is odd because it is the configure script that creates the Makefile in the first place. Here is one loop cycle:

Does anyone have any hints as to what might be causing this? Let me know if there is any other information or magazines that will be helpful.

According to the Makefile only reason configure script make runs like yours is if config.status does not exist or has a timestamp older than configure . You can see it in your Makefile , which says

 # Run the configure script. config.status: $(srcdir)/configure $(SHELL) $(srcdir)/configure $(CONFIG_ARGS)

Building Python 2.7.3 did a great job with me on Snow Leopard. But after I did touch -t 201301010000 configure , my make started a loop like yours because the configure timestamp was now January 1, 2013.

According to your output config.status exists. Therefore, I assume that for some reason, the configure timestamp will be in the future. All you have to do in this case is touch configure to give it the current time, and run make again. Or you can skip the make loop for some time until the date corresponding to the timestamp of your configure

I had this problem on a centos 5 machine and did the following. It seems that this was due to my wrong date. yum install ntp

 - vi /etc/ntp.conf (change to just 1 line: "server ntp.myfloridacity.us") - cp /etc/ntp.conf /etc/ntpd.conf # just to be sure ntpdate -u ntp.myfloridacity.us chkconfig ntpd on service ntpd start
