~0001113 juliensf (administrator) 2020-10-14 21:07	Hi Dirk, The above will only occur if the configure script cannot determine the endianness of the system. Somewhere amongst the output of configure it should say something like: checking whether we can use unboxed 64-bit integers... yes checking whether architecture is big-endian... no checking whether architecture is little-endian... yes checking whether we can use files as locks... yes Do both the endianness checks return "no" on your system? If so, could you please check in config.log and see why those checks are failing? (Or post that file into Mantis and we'll take a look.)

~0001114 juliensf (administrator) 2020-10-14 21:31	BTW, I think the issue here is that Xcode 12 sets -Werror=implicit-function-declaration and the configure script contains several tests (including the ones for testing endianness) that do implicitly declare functions.

~0001115 dirkz (reporter) 2020-10-14 22:45	Hi Julien, both endianness checks return "no": checking whether we can use unboxed 64-bit integers... yes checking whether architecture is big-endian... no checking whether architecture is little-endian... no checking whether we can use files as locks... yes config.log (attached) states: configure:9044: checking whether architecture is big-endian configure:9071: gcc -o conftest -O -Iruntime -Iruntime/machdeps -Itrace conftest.c >&5 conftest.c:146:21: error: implicitly declaring library function 'exit' with type 'void (int) __attribute__((noreturn))' [-Werror,-Wimplicit-function-declaration] exit(0); ^ conftest.c:146:21: note: include the header <stdlib.h> or explicitly provide a declaration for 'exit' 1 error generated. configure:9071: $? = 1 configure: program exited with status 1

~0001116 zs (developer) 2020-10-14 22:55	Julien has already committed a diff to #include stdlib.h. It should show up in the next ROTD, or you could check it out of github, and try it out.

~0001117 juliensf (administrator) 2020-10-14 22:56	Hi Dirk, Thanks for that. The issue is the changed settings for Xcode 12; commit 00d5ede should fix the problem. (It will be included in the next rotd.)

~0001118 dirkz (reporter) 2020-10-15 03:22	Hi Julien, Hi Zoltan, rotd-2020-10-14 builds from source successfully now. Thank you for fixing this.

~0001122 zs (developer) 2020-10-16 07:16	Fix committed 2020 oct 13.
