build constraints exclude all Go files

[lodenrogue]

Hello,

I'm following the installation instructions in the README but I'm facing an issue. I am getting this message after running go build -o ce cmd/main.go:

github.com/proglottis/gpgme: build constraints exclude all Go files in /home/u/go/pkg/mod/github.com/proglottis/gpgme@v0.1.6

This results in no ce binary being created.

Go Version: go version go1.26.4 linux/arm64
OS: Ubuntu 26.04
Docker version: 29.6.0
Current commit: b4ef74b

Container Explorer was developed on Debian based system. Please install these packages on Debian based system:

• libbtrfs-dev
• libgpgme-dev
• pkg-config

[lodenrogue]

Installed the packages but still seeing the same error.

libbtrfs-dev:arm64 6.17.1-1build1
libgpgme-dev       2.0.1-2build1  
pkg-config:arm64   2.5.1-4        

Its worth noting that this issue does not happen on the v0.4.1 tag commit. This only happens on main.

[lodenrogue]

Ok I think I figured it out. I needed to do the following:

export CGO_ENABLED=1

and I needed to install gcc through:

sudo apt-get install build-essential

After this the build command produced the ce binary. I can update the README to include all the necessary packages and env variable.

[lodenrogue]

Updated README in #55

[roshanmaskey]

@lodenrogue Thank you for your contribution and updating the README.

I will close this issue.
