To explicitly specify a path to the `<backtrace.h>` header you could define the *BOOST_STACKTRACE_BACKTRACE_INCLUDE_FILE* to a full path to the header.

-* if you wish to disable backtracing and you use the library in header only mode, you just need to define *BOOST_STACKTRACE_USE_NOOP* for the whole project
 * if you wish to disable backtracing and *BOOST_STACKTRACE_LINK* is defined, you just need link with *-lboost_stacktrace_noop*
+* if you wish to disable backtracing and you use the library in header only mode, you just need to define *BOOST_STACKTRACE_USE_NOOP* for the whole project and recompile it
+
+[section MinGW and MinGW-w64 specific notes]
+
+MinGW-w64 and MinGW (without -w64) users have to install libbacktrace for getting better stacktraces. Follow the instruction:
+
+Let's assume that you've installed MinGW into C:\MinGW and downloaded [@https://github.com/ianlancetaylor/libbacktrace libbacktrace sources] into C:\libbacktrace-master
+
+* Configure & build libbacktrace from console:
+    * C:\MinGW\msys\1.0\bin\sh.exe
+    * cd /c/libbacktrace-master
+    * ./configure CC=/c/MinGW/bin/gcc.exe  CXX=/c/MinGW/bin/g++.exe
+    * make
+    * ./libtool --mode=install /usr/bin/install -c libbacktrace.la '/c/libbacktrace-master'
+* Add info to the project-config.jam in the Boost folder:
+    * using gcc : 6 : "C:\\MinGW\\bin\\g++.exe" : <compileflags>-I"C:\\libbacktrace-master\\" <linkflags>-L"C:\\libbacktrace-master\\" ; 
+* Now you can use a header only version by defining *BOOST_STACKTRACE_USE_BACKTRACE* for your project or build the stacktrace library from Boost folder:
+    * b2.exe toolset=gcc-6 --with-stacktrace
+
+[endsect]
+
+[section Windows deployment and symbol files]
+
+Function names may not be resolved after deployment of your application to a different system.
+
+There are multiple ways to deal with that issue if you distribute PDB files along with your application:
+
+* Link your application and shared libraries with a properly set `/PDBALTPATH` flag, for example `/PDBALTPATH:%_PDB%`. See [@https://docs.microsoft.com/en-us/cpp/build/reference/pdbaltpath-use-alternate-pdb-path official documentation for more info].
+* Set the `_NT_ALT_SYMBOL_PATH` or `_NT_SYMBOL_PATH` environment variables of the target system to the path of the PDBs. See [@https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/symbol-path#controlling-the-symbol-path official documentation for more info].
