Hello Everyone

I've been stuck on a particular compilation error for a few days now and from what I've seen on the internet it can be the result of a few different issues.

In particular I am trying to modify the DSMC initialization code within OF. This has lead to having a modified version of the DSMCCloud.C which defines all of the functions particular to the DSMC solver. Currently the library that contains my modified code compiles just fine my required InInclude directory is generated.

However when I try to compile the initialization Main I get the error at the bottom of this post. To simplify things here is a link to my GitHub just in case there are any questions about my directory structures and various files.

One thing I am currently suspicous of is the fact that I've kept all the same names for classes, files, functions etc while trying to make sure my file and options have the correct inputs to isolate my working directory from the standard openfoam DSMC code and prevent any cross contamination issues.

Feel free to bombard me with questions if you need more precise information, and thank you in advance! Any help is appreciated!

I resolved my issue. One of the things I didnt pick up on when reading the openfoam documentation is that wmake will automatically look in the src directory for all the libraries you want to connect to your program, however if you want to use a custom library stored in the FOAM_USER_LIBBIN you need to first point wmake to that directory and then call out the individual .so files which I was not doing.

In the options file for my initialization executable

EXE_LIBS = \
    -lmeshTools \
    -lfiniteVolume \
    -llagrangian \
    -L$(FOAM_USER_LIBBIN) \
    -lDSMC_mod
