Hi all, In a separate (short) forum, Russ wrote: "Because the pre-built packages are non-module builds and can’t be reused. Sorry. Disable cgo for now or install gcc." I suspect these are related as well: #26993 -- "cmd/go: prebuilt net/http not used"

Just to be clear, the memory used by the values *are *freed. In your example, those are the Person structs. It is only the internal memory used by the map that is not freed. See https://play.golang.org/p/fWOIbvjFjyB. In that test, the "internal" memory that is not freed is about 14 bytes per

[go-nuts] Does go dep support post install script like in php composer?

Hi, I read the dep documentation but was not aware of any hint in it if go dep can handle post install script like in PHP composer. How nice would be a solution to start a bash script automatically right after dep install is executed. -- You received this message because you are subscribed

Hi Ian, Thank you so much for the help. Both of those options did not work. Somehow, the program was able to get buggy libmpfr. I think it might be because I am using /usr/ccs/bin/ld and that ld is giving preference to libraries in /usr/lib. In my case, /usr/lib/libmpc.so.3 pointed to

Re: [go-nuts] What is the proper way to delete a key which holding a pointer in a map

I think there is a major different: the memory allocated for key "index" in hashmap, if you assign m[index] to nil, the allocated memory for hashed key "index" still exist, when delete the allocated memory will be deleted as well. Both will have same affect on the pointer to struct, it will be
