+The option -j descripes the number of parallel processes for the build. In this case make will try to use 4 cores for the build.
 
-# CMake build options
-The cmake-build-environment provides options to configure the build. The following options can be used:
-- BUILD_SHARED_LIBS ( default ON ): Generation of shared libs ( dll for windows, so for Linux ). Set this to OFF to get a static lib.
-- BUILD_FRAMEWORK ( default OFF, MacOnly): Build package as Mac OS X Framework bundle
-- ASSIMP_DOUBLE_PRECISION( default OFF ): All data will be stored as double values.
-- ASSIMP_OPT_BUILD_PACKAGES ( default OFF): Set to ON to generate CPack configuration files and packaging targets
-- ASSIMP_ANDROID_JNIIOSYSTEM ( default OFF ): Android JNI IOSystem support is active
-- ASSIMP_NO_EXPORT ( default OFF ): Disable Assimp's export functionality
-- ASSIMP_BUILD_ZLIB ( default OFF ): Build your own zlib
-- ASSIMP_BUILD_ASSIMP_TOOLS ( default ON ): If the supplementary tools for Assimp are built in addition to the library.
-- ASSIMP_BUILD_SAMPLES ( default OFF ): If the official samples are built as well (needs Glut).
-- ASSIMP_BUILD_TESTS ( default ON ): If the test suite for Assimp is built in addition to the library.
-- ASSIMP_COVERALLS ( default OFF ): Enable this to measure test coverage.
-- ASSIMP_WERROR( default OFF ): Treat warnings as errors.
-- ASSIMP_ASAN ( default OFF ): Enable AddressSanitizer.
-- ASSIMP_UBSAN ( default OFF ): Enable Undefined Behavior sanitizer.
-- SYSTEM_IRRXML ( default OFF ): Use system installed Irrlicht/IrrXML library.
-- BUILD_DOCS ( default OFF ): Build documentation using Doxygen.
-- INJECT_DEBUG_POSTFIX( default ON ): Inject debug postfix in .a/.so lib names
-- IGNORE_GIT_HASH ( default OFF ): Don't call git to get the hash.
-- ASSIMP_INSTALL_PDB ( default ON ): Install MSVC debug files.
+If you want to use a IDE for linux you can try QTCreator for instance. 
 
+## Build instructions for MinGW
+ Older versions of MinGW's compiler (e.g. 5.1.0) do not support the -mbig_obj flag 
+required to compile some of assimp's files, especially for debug builds.
+Version 7.3.0 of g++-mingw-w64 & gcc-mingw-w64 appears to work.
+
+Please see [CMake Cross Compiling](https://cmake.org/cmake/help/latest/manual/cmake-toolchains.7.html#cross-compiling) for general information on CMake Toolchains.
+
+Some users have had success building assimp using MinGW on Linux using [polly](https://github.com/ruslo/polly/).
+
+The following toolchain, which is not maintained by assimp, seems to work on Linux: [linux-mingw-w64-gnuxx11.cmake](https://github.com/ruslo/polly/blob/master/linux-mingw-w64-gnuxx11.cmake)
+
+The following toolchain may or may not be helpful for building assimp using MinGW on Windows (untested):
+ [mingw-cxx17.cmake](https://github.com/ruslo/polly/blob/master/mingw-cxx17.cmake)
+
+Besides the toolchain, compilation should be the same as for Linux / Unix.
+
+## CMake build options

+- **BUILD_SHARED_LIBS ( default ON )**: Generation of shared libs ( dll for windows, so for Linux ). Set this to OFF to get a static lib.
+- **BUILD_FRAMEWORK ( default OFF, MacOnly)**: Build package as Mac OS X Framework bundle

 APIs are provided for C and C++. There are various bindings to other languages (C#, Java, Python, Delphi, D). Assimp also runs on Android and iOS.

 Additionally, assimp features various __mesh post processing tools__: normals and tangent space generation, triangulation, vertex cache locality optimization, removal of degenerate primitives and duplicate vertices, sorting by primitive type, merging of redundant materials and many more.
 
 This is the development repo containing the latest features and bugfixes. For productive use though, we recommend one of the stable releases available from [Github Assimp Releases](https://github.com/assimp/assimp/releases).
