Note that the devtools equivalents of 'R CMD build/check/install' are devtools::build(), devtools::check(), devtools::install(). devtools::load_all() has a different purpose.

In general you would not need to do that, or do that: - A package knows how to turn files in src/* into a .so (and a .dylib and a .dll none of which you need to explicitly, a huge win for you) - A package knows how to load a dynamic library declared in NAMESPACE | Building this works fine in RStudio with devtools::load_all('.'), but | when I try to run R CMD INSTALL, I get the error: package or namespace | load failed in library.dynam(lib, package, package.lib): shared object | 'filename.so' not found.

Thanks for your help! As said, R knows where to find a package's shared library file. For the rest, it is (on Linux) ld.so and its documentation but you (as far as I can remember) cannot set LD_LIBRARY_PATH from within a running R session. It might help if you described your problem in more detail with a reproducible example.
