Hey All,
Im not sure what I am doing wrong here so would appreciate some insight.
In Nix Pill 10.1 (Nix Pills | Nix & NixOS) it says the following:
That means we can source our
builder.sh, and it will build the derivation. You may get an error in the installation phase, because the user may not have the permission to write to/nix/store:
[nix-shell]$ source builder.sh …
It didn’t install, but it built. Things to notice:
We sourced builder.sh, therefore it ran all the steps including setting up the PATH for us.
The working directory is no more a temp directory created by nix-build, but the current directory. Therefore, hello-2.10 has been unpacked there.
We’re able to cd into hello-2.10 and type make , because now it’s available.
In other words, nix-shell drops us in a shell with the same (or almost) environment used to run the builder!
When I attempt the code source bulder.sh in the nix-shell I get the following error (as described in the pill above):
make[2]: Leaving directory ‘/home/andrew/nix_pills/testing/hello-2.10/po’
make[2]: Entering directory ‘/home/andrew/nix_pills/testing/hello-2.10’
make[3]: Entering directory ‘/home/andrew/nix_pills/testing/hello-2.10’

make[1]: Leaving directory ‘/home/andrew/nix_pills/testing/hello-2.10’
make: *** [Makefile:2371: install] Error 2
My expectation would be that I would still be in the nix-shell and that I woiuld just cd into the hello folder and make the program.
But instead I am dropped out of nix-shell and back to my standard shell. This means that i need to reopen nix.shell, source $setup go to the folder and make.
Why am I being dropped out of the nix-shell? Is this expected? I would have thought after the make error I would still be in the nix-shell and be able to just cd to hello and then run make?
Thanks
