help :undefined reference to __morestack

[b1gcat]

Hi sir,

I follow your tips to compile the gccgo successully, but something wrong happen after i use gccgo to compile hello world.

helloworld.go:(text+0x195): undefined reference to __morestack
Can you give me some hints to solve the problem?

Perhaps try -fsplit-stack?

@mkschreder
where should I put ' -fsplit-stack' ?
by the way I have enabled SSP_CONFIG, it that use split-stack default?

[mkschreder]

You would pass it as argument to gccgo when you compile your hello world
program. It may or may not solve your issue. If it does not then await
other replies.

My old experience is to compile with debug info (the -g)and link libgo statically.

Thanks guys, I still cannot work it out.
Here is the details:

@zsdev2015 Hi, did you find out how to do with it? I encounter almost the same errors as the log you posted here.
Thanks
