Hover install fails in Conda environment #614

Closed skeledrew closed 3 years ago

Installing

$ go version
go version go1.16.6 linux/amd64
$ GO111MODULE=on go get -u -a github.com/go-flutter-desktop/hover
# runtime/cgo
cgo: exec x86_64-conda-linux-gnu-cc: exec: "x86_64-conda-linux-gnu-cc": executable file not found in $PATH
$ which gcc
/usr/bin/gcc

I have installed Go within a Conda environment, and and would like hover to be installed there as well. Conda was installed via the script to $HOME/.conda, dependencies installed with sudo apt install libgl1-mesa-dev xorg-dev and the environment created with conda create -n my_env go.

OS: Kubuntu 20.04 LTS

Check the output of which x86_64-conda-linux-gnu-cc - where does it show?

That link was very helpful, thanks. A conda install gcc_linux-64 resolved the issue.

Just one other minor thing. I notice hover was installed into $HOME/go/bin/hover instead of path/to/env/bin/hover. Not sure if it's due to how the install was invoked, or if it's just a "Go thing", but it'd be nice if it respected the given environment setup.

That is how go works.

OK, thanks.

I'm now running into another issue:

$ ~/go/bin/hover run --target lib/main.dart
[...]

💪 Building with sound null safety 💪

Read this section of the hover readme:

Install these dependencies:

You need to make sure you have a C compiler.
The recommended C compiler are documented here.
You need to make sure you have dependencies of GLFW:
- On macOS, you need Xcode or Command Line Tools for Xcode (xcode-select --install) for required headers and libraries.
- On Ubuntu/Debian-like Linux distributions, you need libgl1-mesa-dev xorg-dev packages.
- On CentOS/Fedora-like Linux distributions, you need `libX11-devel libXcursor-devel libXrandr-devel libXi

This one is important: https://github.com/golang/go/wiki/InstallFromSource#install-c-tools

TLDR: Install with conda GLIBC share lib.
