Hi. I am using ubuntu 20.04 LTS and I followed this chapter to install SMOKE ([https://www.cmascenter.org/smoke/documentation/4.7/html/ch12s03.html](https://www.cmascenter.org/smoke/documentation/4.7/html/ch12s03.html)) and installed completely without issues. the next step is **(** Download and compile the I/O API library from the [I/O API home page](https://www.cmascenter.org/ioapi/). The I/O API can be installed in `$SMK_HOME` /subsys/ioapi\*\*)\*\* but I saw ioapi-3.2 on that path and their directories was there. My question is do I need to install ioapi-3.2 (like run configure or make or make install)or not and it is installed automatically by following the steps in section 12.3? Thanks. ---

[https://www.cmascenter.org/ioapi/](https://www.cmascenter.org/ioapi/) is a broken link. It should be [https://www.cmascenter.org/ioapi/documentation/all\_versions/html/AA.html](https://www.cmascenter.org/ioapi/documentation/all_versions/html/AA.html) The I/O API installation instructions are at [https://cjcoats.github.io/ioapi/AVAIL.html#build](https://cjcoats.github.io/ioapi/AVAIL.html#build) or the matching page [[https://www.cmascenter.org/ioapi/documentation/all\_versions/html/AVAIL.html#build](https://www.cmascenter.org/ioapi/documentation/all_versions/html/AVAIL.html#build)]]([https://www.cmascenter.org/ioapi/documentation/all\_versions/html/AVAIL.html#build](https://www.cmascenter.org/ioapi/documentation/all_versions/html/AVAIL.html#build)])on the CMAS site. ---

I knew these sites exist, my question is something else. in section 12.3 of smoke documentation, the second step is to download and compile the I/O API library on the recommending path (`$SMK_HOME` /subsys/ioapi ). but I/O API lib exists in the path. what should I do? It means ioapi has installed completely and I do not need to install it or it is just a package of ioapi that it has just extracted. ---

Sorry for misunderstanding your question. In the SMOKE _src_ directory is a file _Makeinclude_ that sets various options for compiling SMOKE. In it, there is a _make_-variable `IOBASE`. Edit the file to set that variable to the installation directory for the I/O API. In my case, for example, I’ve installed the I/O API under my home directory for use by “evrything”, so that I have `IOBASE = ${HOME}/ioapi-3.2` ---

Thanks a lot. 🙃 🙏 🙏 I have another question about creating the symbolic link that is written on this page ([https://www.cmascenter.org/smoke/documentation/4.7/html/ch12s04.html](https://www.cmascenter.org/smoke/documentation/4.7/html/ch12s04.html)) after downloading and installing I/O API lib. what symbolic link did you create for yourself with regarding you installed I/O API lib in `${HOME}/ioapi-3.2` ---

`BIN` is probably `Linux2_x86_64ifort`. If not, you will need to adjust your _ASSIGNS_ file. Assuming your I\*/O API is installed at base directory _${HOME}/ioapi-3.2_: ``` ln -s ${HOME}/ioapi-3.2/ioapi $SMK_HOME/subsys/ioapi/ioapi ln -s ${HOME}/ioapi-3.2/${BIN} $SMK_HOME/subsys/ioapi/${BIN} ``` ---

I installed ioapi-3.2-gompi-nocpl by EasyBuild yesterday and I changed IOBASE from Makeinclude. now I run `ln -S /home/farzad/.local/easybuild/software/ioapi/3.2-2020111-gompi-2020a/${BIN} $SMK_HOME/subsys/ioapi/${BIN}` but I received this error BIN: Undefined variable.

The build-instructions for the I/O API are here: [https://cjcoats.github.io/ioapi/AVAIL.html#build](https://cjcoats.github.io/ioapi/AVAIL.html#build), or at the matching CMAS-site page. In particular: 1. _setenv BIN …_, followed by one of the make commands below, as appropriate for your configuration(s). Alternatively, _make BIN=_ (where note that a command-line variable-definition overrides the environment variable definition). ---

On second thought, you’re talking about _running_ SMOKE. See the SMOKE instructions, but generally your ASSIGNS file is responsible for setting this environment variable… ---

@cjcoats. Hi again. 🙂 How can I adjust my ASSIGNS file to change `Linux2_x86_64ifort` to `Linux2_x86_64gfort`? Because I have a problem to create this symbolic link `ln -s ${HOME}/ioapi-3.2/${BIN} $SMK_HOME/subsys/ioapi/${BIN}` This `env | grep BIN` says `BIN=Linux2_x86_64gfort` Could you help me? Thanks and Best regards. ---

With _vi_ or _emacs_ or _gedit_ or _kate_ or _nano_ or (my favorite) _nedit_ or … Make a backup first, of course. ---
