cgo error on Mac OSX Mountain Lion

[Olivier Van Acker]

When I run .mkall.sh in src/pkg/syscall to generate code I get the following error:

./mkall.sh 

In file included from _const.go:9:

/usr/include/sys/socket.h:705: error: expected specifier-qualifier-list before 'user64_addr_t'

/usr/include/sys/socket.h:720: error: expected specifier-qualifier-list before 'user32_addr_t'

Is this related to this issue: http://codereview.appspot.com/4244052/ ?

why you want to run mkall.sh?

it's possible that mkall.sh and related source files are out-of-date. 

i don't think so.

I'm adding SCTP network functionality to Go and I need to add the relevant structures/socket api calls to Go before I can add it to the network library

ok. then you need to try to manually do what mkall.sh do step by step and isolate the step

that is causing the error.

it should be a call to 'go tool cgo', and you can add -debug-gcc flag to enable debugging output

so that you can know the exact gcc invocation command line and also its input file.

i think you know how to proceed from here on.

Found it:

gcc -Wall -Werror -o_obj/_cgo_.o -gdwarf-2 -fno-eliminate-unused-debug-types -c -xc -m64 /usr/include/sys/socket.h 

/usr/include/sys/socket.h:500: error: expected specifier-qualifier-list before ‘user64_addr_t’

/usr/include/sys/socket.h:515: error: expected specifier-qualifier-list before ‘user32_addr_t’

/usr/include/sys/socket.h:664: error: expected specifier-qualifier-list before ‘user64_addr_t’

/usr/include/sys/socket.h:672: error: expected specifier-qualifier-list before ‘user32_addr_t’

 

Double checked and found out this is not the original socket.h but a modified version (cause of adding sctp), re-installing the Command Line Tools (XCode installer) solved the problem, 

Thanks
