[Python-Dev] socket module build failure (original) (raw)

I work on Ubuntu Jaunty for my cpython development work - an old version, I know, but still quite serviceable and has worked well for me over many months. With the latest default cpython repository, however, I can't run the regression suite because the socket module now fails to build:

gcc -pthread -fPIC -g -O0 -Wall -Wstrict-prototypes -IInclude -I. -I./Include -I/usr/local/include -I/home/vinay/projects/python/default -c /home/vinay/projects/python/default/Modules/socketmodule.c -o build/temp.linux-i686-3.3-pydebug/home/vinay/projects/python/default /Modules/socketmodule.o .../Modules/socketmodule.c: In function ‘makesockaddr’: .../Modules/socketmodule.c:1224: error: ‘AF_CAN’ undeclared (first use in this function) .../Modules/socketmodule.c:1224: error: (Each undeclared identifier is reported only once .../Modules/socketmodule.c:1224: error: for each function it appears in.) .../Modules/socketmodule.c: In function ‘getsockaddrarg’: .../Modules/socketmodule.c:1610: error: ‘AF_CAN’ undeclared (first use in this function) .../Modules/socketmodule.c: In function ‘getsockaddrlen’: .../Modules/socketmodule.c:1750: error: ‘AF_CAN’ undeclared (first use in this function)

On this system, AF_CAN is defined, but in linux/socket.h, not in sys/socket.h.

From what I can see, sys/socket.h includes bits/socket.h which includes asm/socket.h, but apparently linux/socket.h isn't included.

Is this a bug which doesn't show up on more recent Linux versions, or is Jaunty no longer supported for Python development, or could something be wrong with my configuration? BTW nothing has changed on the machine other than updates to Jenkins and the cpython repo.

Any advice would be appreciated!
