@Gavin @Edward: Success! The program is now executing as expected, *thanks to all of your helpful suggestions.* Here's what I did: 1. added --with-chrono to my b2 command, which placed .a and .dylib files for chrono in stage/lib. 2. after invoking the following compiler command: g++ -v -Wall -L ${BOOST_ROOT}/stage/lib -lboost_chrono -lboost_date_time -lboost_system -lboost_system -I${BOOST_ROOT} -o main main.cpp I added to my RPATH using install_name_tool: sudo install_name_tool -add_rpath ${BOOST_ROOT}/stage/lib main

From what I have read from this article here: https://medium.com/@donblas/fun-with-rpath-otool-and-install-name-tool-e3e41... This command appends to the RPATH (@rpath), which is used by LC_LOAD_DYLIB to locate shared library dependencies for the executable.

After executing these two commands, my program runs successfully! *Thank you.* However, the learning never ends. That said, I have a bit of an unrelated follow-up question if that is okay. If not, feel free to shun me and I will look elsewhere for an answer. Running these two commands from my terminal is painful and tedious. For troubleshooting, I don't mind, but I want to move toward automation. 1. I tried putting these two commands into a simple script. When I ran the script, main could not be found. *How would I ensure that the main executable from the g++ invocation is outputted into the cwd before the install_name_tool command is executed?* The script I wrote here is just for the sake of experimentation and learning. Ideally, I would use a build tool (i.e. make) for this sort of thing, which I am actually reading about right now. It should be okay to close this issue after my last question is answered/shunned. Thanks again for all of your helpful suggestions, I am starting to like this community already. - AJ On Fri, Jan 31, 2020 at 4:01 AM wrote:

Hello Boost-Mailing-List,

I have a question about the boost interprocess library - and I hope I can explain it correctly.

I looked at the "Quick guide for the impatient" about the interprocess library - but I'm not sure if I can use this for our purpose. The main goal is to insert a STL vector (or different container) in a predefined portion of an already existing shared memory. The main problem is, that we cannot use the managed_shared_memory code from boost, because we rely on a different API to allocate the shared memory between Windows and other devices. Also the container should be placed at a fixed offset inside the created shared memory.

I'm a complete newbie with boost and the interprocess library, that is why I'm not sure which interface I have to provide for the interprocess vector to be setup correctly. I hoped I could do something like:

new (srh_mem_base + offset) boost::interprocess::vector<allocator>;

I tried looking into the headers of the library to get an idea of that, but I honestly got lost.

I'm really sorry if this a stupid or obvious question - and I thank for any help in advance!
