go 1.18 in google.cloud

Asked 2022-Apr-11 at 13:00

Description

I am trying to install a library from a go v1.18 program to access Google Cloud. Previously, the "go get" command was used, but since version 1.18, it is no longer available. It seems to use go install, but I get an error when executing the command.

Answered 2022-Apr-09 at 21:13

go install is used to install binary programs available on the package. Usually command line tools.

go get, until go1.18, was used to update packages and install programs, they change it by split in several programs

Seems there is nothing to install. Also the main package is not bigquery but cloud.google.com/go

If you want to install a dependency, if you are using vendorized modules you can do

$ go get -u cloud.google.com/go/bigquery

$ go mod tidy

$ go mod vendor

If not, you may try it by running go mod init first

QUESTION

How can I find source code of printf in macOS?

Asked 2022-Mar-23 at 06:38

Sorry for my bad english.

I'm using macOS 12.3 in M1 Pro MacBook Pro

I want to know about source code of printf in C standard library.

I can find stdio.h file in usr/include directory.

But I can't find printf.c or stdio.c file in same directory.

And I think Apple Open Source's printf.c is too complicate, dosen't looks like a real code in macOS and dosen't helpful for me. Is that Apple Open Source printf.c code is really used in macOS?

The newest Apple Open Source libc implementation of vfprintf (which is the generic underlying function that plain printf calls) can be found here on opensource.apple.com.

It's about 1400 lines, and yes, it is complex.

Some other alternate implementations (which are complex too) are:

musl libc: 696 lines
GNU glibc: 2289 lines
uClibc: 1928 lines

QUESTION

C function for combining an array of strings into a single string in a loop and return the string after freeing the allocated memory

Asked 2022-Mar-18 at 07:54

I'm working on a procfs kernel extension for macOS and trying to implement a feature that emulates Linux’s /proc/cpuinfo similar to what FreeBSD does with its linprocfs. Since I'm trying to learn, and since not every bit of FreeBSD code can simply be copied over to XNU and be expected to work right out of the jar, I'm writing this feature from scratch, with FreeBSD and NetBSD's linux-based procfs features as a reference. Anyways...

Under Linux, $cat /proc/cpuinfo showes me something like this:

This is something to do with the way os.walk interfaces with Apple's NTFS handler. If you use a proprietary NTFS tool for MacOS, then os.walk works as expected.

Check out my alternative code for pathlib to walk with Apple NTFS or any other.

Solving environment: failed with current_repodata.json, will retry with next repodata source. Conda Fails to Create a new env

Asked 2022-Jan-23 at 06:00

** Conda Fails to Create a new env: stuck at "Executing transaction"**

I am working with a MacOS, BigSur 11.6, and have updated conda and mamba

conda update --all

conda update mamba

and, following guidance from a software installation guide I tried to create a new env:

conda create -n fermi -c conda-forge -c fermi fermitools python=3 clhep=2.4.4.1

Also tried with the dev version:

conda create -n fermi-2.0.24 -c conda-forge -c fermi/label/dev fermitools=2.0.24

and with mamba

mamba create -n fermi -c conda-forge -c fermi fermitools python=3 clhep=2.4.4.1

All trials get stuck in " executing transaction \ " (> 1h)

when hitting ctrl+c, all trials show the same error msg:

" ERROR conda.core.link:_execute(699): An error occurred while installing package 'conda-forge::gdk-pixbuf-2.42.6-h2e6141f_0'. " " Rolling back transaction: done "

my uname -v:

Darwin Kernel Version 20.6.0: Mon Aug 30 06:12:21 PDT 2021; root:xnu-7195.141.6~3/RELEASE_X86_64

my conda --version

conda 4.10.3

There seems to be a long standing discussion about similar issues here. Some argue that hitting "enter" solved the problem after " executing transaction \ " was running for a long time. It would be great, but did not worked.

The issue #6986 seems to persist and it is not clear how to deal with it.

Any ideas on how to approach this? Thank you in advance!

Looking for resources on the error " Solving environment: failed with current_repodata.json, will retry with next repodata source. "

Then, reading: link1 , link2 , link3 (check the comment from "glass-ships") , link4

It seems the following can help:

conda update conda -c conda-canary

conda config --set channel_priority false

conda create --name your_env_name

conda activate your_env_name

conda install XXXXXX

then conda activate your_env_name and the tool is working just fine.

Try env ARCHFLAGS="-arch x86_64"

(that works for me for other Python-related tools, I don't use pyenv myself).

Rationale: modern macOS supports 2 architectures: intel (x86_64) and m1 (arm-something). Compiling for only one architecture is easier.
