No appropriate GCC found, but my system uses Clang

[esmaeilmirzaee]

I have tried to install nvm on Freebsd, but I've got the following error. It is worth mentioning, I use zsh, ohmyzsh on xfce Terminal. Would you please help me with the error?

   Installing latest LTS version.

      Please make sure you have a C compiler installed on your system and/or

      it in a non-standard prefix.

• How did you install nvm? (e.g. install script in readme, Homebrew): instruction in readme file

• What steps did you perform? just instruction on the readme file

• What happened? The system, installation script, identified Clang as a C compiler, but later claimed about no appropriate C compiler.

• What did you expect to happen? No idea

• Is there anything in any of your profile files (.bashrc, .bash_profile, .zshrc, etc) that modifies the PATH? I think so, ohmyzsh.

You may need to set the CC or CCX env vars; but also, freeBSD is tricky because node doesn't support it. See #130 and #1207.

Thank you so much for provided links. I read them all, and I hope, I understand what the problem is. At this time, I think to help and put some resource to improve the issue. Although I am not sure I would be able to do the task perfectly, I like to put the effort because I believe that it could help many.

PS: I will remove the topic ASAP If this is not the right place to add this please let me know.

Sure, what’d you have in mind?

[esmaeilmirzaee]

I am thinking about moving forward step by step. First, providing the LTS installation package for the current version of FreeBSD. To do so, I think we have to follow the installation steps in a bare/fresh FreeBSD machine. We probe the potential errors or requirements, so then we can customise the installation process in NVM (especially requirements could be added to the NVM script).

Also, I am not sure about the consequences (Copyright issues, and regularities in both NodeJS and FreeBSD), but we can provide the specific package for FreeBSD by providing patches as needed.

[ljharb]

I'm very hesitant to add freebsd-specific patches to nvm, especially since they'll vary widely by node version.

[esmaeilmirzaee]

I see. Actually, I tried a bunch of methods to solve the issue. First, it is kind of converting FreeBSD to a Linux. In this approach, installing GNU tools (ie gcc/g++, gmake) solves the issue. Second, providing a new make file, which I really looking forward to starting.

[ljharb]

So given that this is a known limitation of node itself, i think this should be closed.
