If you were not able to invoke the precompiled executables from the SMOKE package and got the error message above, you probably need to compile SMOKE to create the executables on your Linux machine. Please follow the instruction on how to compile the SMOKE modeling system. [https://www.cmascenter.org/smoke/documentation/4.7/html/ch12s04.html](https://www.cmascenter.org/smoke/documentation/4.7/html/ch12s04.html) If you are able to compile the SMOKE codes, then please follow another bug ticket that could help you to compile your own SMOKE executables: > [@SMOKE shared libraries error](https://forum.cmascenter.org/t/smoke-shared-libraries-error/1035): > > I am new to SMOKE and emissions modeling in general and I am having an issue trying to run the test case in SMOKE. I am getting the error below. Any help would be greatly appreciated.
