"gcc": executable file not found in %PATH% when using mongo-go-driver - mongodb

I want to use mongodb driver.But I get the following error:
go.mongodb.org/mongo-driver/vendor/github.com/DataDog/zstd
exec: "gcc": executable file not found in %PATH%

The issue is that your library depends on gcc to run.
1. Linux/Containers
If you are running in a container, you can try two options:
you can build your app without CGO with the following command:
RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o yourBinary
You can try to install gcc into your container. If it is an alpine based container, run
RUN apk update && apk add --no-cache gcc
You could also need musl-dev package, but you should try without it first.
2. Windows
Since MacOS and most Linux distros come with GCC, I guess you could be using Windows. In this case, you need to install MinGW.

I know this is old but I ran into this problem too, About Alexey answer, on windows, you should install MinGW and add the path to win environment. You should follow this. In case MinGW did not work, you can install this one which worked perfectly for me on windows.

Mac M1 Homebrew Perl Carton Net::SSLeay is loading libcrypto in an unsafe way

I'm trying to install Net::SSLeay with Carton.
The installation fails with this message
Configuring Net-SSLeay-1.90 Running Makefile.PL Do you want to run external tests?
These tests *will* *fail* if you do not have network connectivity. [n] n
*** Found LibreSSL-2.8.3 installed in /usr
*** Be sure to use the same compiler and options to compile your OpenSSL, perl, and Net::SSLeay. Mixing and matching compilers is not supported.
Checking if your kit is complete... Looks good
WARNING: /opt/homebrew/Cellar/perl/5.32.1_1/bin/perl is loading libcrypto in an unsafe way -> N/A
I've tried this with system perl, brew perl and multiple perlbrew perls.
Google came up with a temp solution to build homebrew using x86_64 architecture.
This did work for the libcrypto error, but gave me a whole different set of issues including mysql not running anymore.
Other "solutions" that I've tried are symlinking libssl & libcrypto as suggested by numerous other posts, all sadly without success.
Any ideas how to fix this or work around this without having to reinstall all brew packages as x86_64 ?
Quick Workaround
If you are looking for a quick workaround follow these steps.
Run carton bundle to create a vendor cache directory.
Go to cached tarball 'cache/authors/id/C/CH/CHRISN/' and unpack tar -xvzf Net-SSLeay-1.90.tar.gz
Edit Makefile.PL, change my $prefix = find_openssl_prefix(); to
my $prefix = '/opt/homebrew/opt/openssl#1.1'; ** adjust to your openssl location.
Save and create new tarball tar -czvf Net-SSLeay-1.90.tar.gz Net-SSLeay-1.90
Run carton install --cached to use the altered version
Hope this helps anyone in search of workaround
You can solve this in two steps:
upgrade ExtUtils::MakeMaker to at least version 7.58 (e.g. cpanm ExtUtils::MakeMaker)
install openssl via macports (sudo port install openssl) or homebrew (brew install --cask openssl)
After the Monterey update this broke again also on the x86_64 architecture, but just symlinking your latest openssl (where ever it is, depending how you have installed it) seemed to fix this. Example:
$ export OPENSSL_PREFIX=[find your openssl installation]
$ sudo ln -s $OPENSSL_PREFIX/lib/libssl.dylib /usr/local/lib/
$ sudo ln -s $OPENSSL_PREFIX/lib/libcrypto.dylib /usr/local/lib/
Better workaround:
I entered export OPENSSL_PREFIX=/opt/homebrew/opt/openssl#1.1 in my shell and then ran cpan. I checked the code in Makefile.PL and the first thing the function find_openssl_prefix does is to check the OPENSSL_PREFIX environment variable. If it is set, then it the function will return its contents.
Add the variable to your .profile, .cshrc, .bashrc, .zshrc, or whatever rc file your shell uses and you never have to worry about it again!!

Installation of protoc-gen-grpc-web

I am currently working on using grpc-web to write a simple client for my service. I have created a service.proto file which was successfully compiled using protoc. The problem arose when I tried to generate the gRPC-Web service client stub using the plugin protoc-gen-grpc-web which doesnt work despite having installed the latter.
Got the following error :
protoc -I=./ service.proto --grpc-web_out=import_style=commonjs,mode=grpcwebtext:./
protoc-gen-grpc-web: program not found or is not executable
--grpc-web_out: protoc-gen-grpc-web: Plugin failed with status code 1.
Any suggestions on how to solve this issue? Thank you!
You'll need to make the protoc-gen-grpc-web plugin executable and move it to a directory that is discoverable from your PATH environment variable.
From grpc-web/README:
For example, in MacOS, you can do:
$ sudo mv ~/Downloads/protoc-gen-grpc-web-1.2.1-darwin-x86_64 \
/usr/local/bin/protoc-gen-grpc-web
$ chmod +x /usr/local/bin/protoc-gen-grpc-web
You don't even have to install the plugin globally and make it discoverable from your PATH:
protoc accepts --plugin arguments to point to a required plugin. For protoc-gen-grpc-web (as for many others) there's even npm support, so you can get it with npm i --save-dev protoc-gen-grpc-web and then run protoc with --plugin=protoc-gen-grpc-web=./node_modules/.bin/protoc-gen-grpc-web
I'm using MacOS. You need to install this first with brew
$ brew install protoc-gen-grpc-web
The best solution that I could use for Linux based system was globally installing protoc-gen-grpc-web. This directly takes the files from the /bin of the node_modules files created globally across your system
sudo npm install -g protoc-gen-grpc-web

Cpplint could not find executable

I am trying to activate cpplint within vs code. I have installed it in Anacanda environment where executable
/home/ubuntu/anaconda3/bin/cpplint
I have a link to it
ls -l /home/ubuntu/anaconda3/bin/cpplint
Unfortunately per visual code cpplint extension still getting error of "Cpplint could not find executable"
Please, advice to configure it correctly.
Download and install
sudo apt-get install python-pip
pip install --user cpplint
Verify install result
ls -l /usr/local/bin/cpplint
If you still have issues check cpplint.cpplintPath and verify the execution path is set correctly.
Also, if you installed cpplint into ~/.local/ directories, by default ~/.local/bin is not included in PATH. So to fix just that add:
export PATH=$PATH:~/.local/bin/
to your ~/.bashrc

How to start IDLE that comes with Python 3.6

I am using Linux Mint 18. I installed Python 3.5 and 3.6 using apt-get in the terminal. I can open IDLE of Python 2.7 and 3.5 using commands idle and idle3 respectively. How can I access IDLE that comes with Python 3.6?
Try the command idle3.6. python3 and idle3 are still associated with your system Python, which is 3.5.
Simply typing in idle3.6 should work just like carusot42 mentioned. If it doesn't work, perhaps you might want to see if everything else is installed correctly. Here are the steps I followed which worked perfectly fine for me. I am also running Linux Mint 18. The steps that I followed were:
Installed the prerequisites of Python. Do that by typing in the following commands -
sudo apt-get install build-essential checkinstall
sudo apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev
Download Python using the following command and extract it (use your desired location) -
cd /usr/src
wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
sudo tar xzf Python-3.6.0.tgz
The next step is to compile Python source. To do that type in the commands below-
cd Python-3.6.1
./configure
sudo make altinstall
make altinstall is used to prevent replacing the default Python binary
file /usr/bin/python
You should be good to go. You check your Python version by typing python3.6 -V in the terminal.
Once you do that, type in idle3.6 and then Python 3.6.1 shell should open for you.
The Software Manager in Linux Mint lists the Python Packages and IDLE Packages
separately. After you install Python, go look up the associated IDLE package in the Software Manager and install it. Reboot and it should work fine. It worked for me.

How can I run madge on Windows

The instructions for madge are only good for a linux system (it requires sudo to get the command line part set up). Is there a way to run it on windows?
It turns out to be very simple. To install madge:
npm install madge
Then to set it up for the command line:
npm -g install madge
You can then run it with a command of:
madge
For typescript generate .js files do:
madge -f amd -c .
and you'll get the circular report. You need the "-f amd".
