That’s a little terse. Can you do a differential diagnosis against the CI build which is working fine?

Are you building inside the build container? (Eg by running make)

Jun 11 '20 05:06 bboreham

I don't want to run in a container, I just want to run on the host, so I just need to compile a binary program

Jun 11 '20 06:06 luomoyisheng

Moreover, I need to compile binary programs of other architectures after X86 compilation, which is my requirement.

Jun 11 '20 06:06 luomoyisheng

Suggest you take a look at what is installed by the build container, as a guide to what you’ll need on your host.

Jun 11 '20 06:06 bboreham

Note make prog/scope will give you the plain binary, built by a container.

Jun 11 '20 06:06 bboreham

OK, I'll try

Jun 11 '20 06:06 luomoyisheng

Can't I build binaries directly from makefiles? Can only be built from containers? I have some packages that can't be downloaded eg: package golang.org/x/lint/golint: unrecognized import path "golang.org/x/lint/golint" (https fetch: Get https://golang.org/x/lint/golint?go-get=1: dial tcp 216.239.37.1:443: connect: connection refused)

Jun 11 '20 06:06 luomoyisheng

If you install all dependencies on the host then make prog/scope BUILD_IN_CONTAINER=false.

Jun 11 '20 07:06 bboreham

OK，I'm a little busy this afternoon. I haven't replied to you. Thank you very much for your help

Jun 11 '20 12:06 luomoyisheng

make prog/scope BUILD_IN_CONTAINER=false report errors： mkdir -p prog/staticui esc -o prog/staticui/staticui.go -pkg staticui -prefix client/build client/build make: esc：command not found make: *** [prog/staticui/staticui.go] error This esc doesn't look like a system command

Jun 12 '20 03:06 luomoyisheng

esc is a dependency of the build. For the provided build process it is installed here: https://github.com/weaveworks/scope/blob/e6faa2ba4bf842bb81993a64232554c281ced644/backend/Dockerfile#L25

Jun 12 '20 08:06 bboreham

Ok, I thought it was a linux system command, so I yum install esc.

Jun 12 '20 11:06 luomoyisheng

The container is compiled, but I want to compile other architectures, such as mips64le, how do I modify the Makefile and perform compilation command

Jun 17 '20 08:06 luomoyisheng

We do a couple of cross-platform builds in CI to check it doesn't break: https://github.com/weaveworks/scope/blob/e6faa2ba4bf842bb81993a64232554c281ced644/.circleci/config.yml#L116

Some features are stubbed out but I think that's based on OS rather than CPU.

Jun 17 '20 10:06 bboreham

Ok， thanks, I don’t have an arm system. I know that the go code can be cross-compiled. I want to cross-compile the arm architecture on x86_64. Is this feasible?

Jun 17 '20 11:06 luomoyisheng

I made the gcc toolchain of mips64 on x86_64, and executed the compilation but the above problem still occurred

Jun 18 '20 08:06 luomoyisheng

I want to cross-compile the arm architecture on x86_64. Is this feasible?

The line I gave you does exactly that.

vendor/github.com/docker/docker/pkg/system/stat_linux.go:11:3: cannot use s.Rdev (type uint32) as type uint64 in field value

Possibly a newer version of the Docker code would work, but updating that may need changes elsewhere to fit with different interfaces.

collect2: ld terminated with signal 11 [Segmentation fault]

This is a bug in the linker.

Jun 18 '20 08:06 bboreham

Ok, thanks, let me try

Jun 18 '20 08:06 luomoyisheng

go get github.com/docker/docker/pkg/system

output：go: github.com/docker/[email protected]+incompatible: invalid pseudo-version: git fetch --unshallow -f https://github.com/docker/libcontainer in /root/go/pkg/mod/cache/vcs/64bebe9f90303f9d2c71fa74be10602c56b1856196b58f28075dffdbe7d0b953: exit status 128: fatal: git fetch-pack: expected shallow list

I am eager to compile a program with mips64le architecture, but I feel I can do nothing. You have communication software, can I add you? In order to solve the problem, I can pay a little money to thank you for your help.
