To know which dll libraries need to be bundled with your application, the safest way is to profile your app at runtime, because some libraries may be loaded just at runtime (e.g. Qt plugins). We use MSYS2 (https://www.msys2.org/) for compiling our apps with GCC and MSYS2 contains the strace package which we use here to get a list of loaded dll libraries:

/usr/bin/strace ANY_APP.exe 2>&1 \
| tee out.log \
| grep -a -E '^--- Process .* loaded .*\.dll' \
| cut -d' ' -f 5- \
| sed 's/\.dll.*/.dll/' \
| sort -u

# This implementation doesn't directly decode hidraw stream, but uses

Build instructions:

git clone https://github.com/ReactiveX/RxCpp.git
make
./main

This is the output of the program:

After upgrading to XCode 8 and MacOS to 10.12.2, I was getting a linker error when linking with macport's GCC 6: "ld: unexpected token: !tapi-tbd-v2", so this script creates a lybrary symlink for every .tbd file in a given MacOSX SDK path, so that the linker doesn't need the .tbd file at all.

Stripping symbols from a static library archive overcoming the error: "strip.exe: cannot create tempdir for archive copying (error: File exists)", when the library contains more than a few object files. The problem is in mktemp("stXXXXXX") which is able to create only 26 unique filenames on the MinGW system "mingw32_4.9.2-posix-sjlj-rt_v3-rev1"
