Reported to work flawlessly is e.g. clang \u003e= 3.1.\n\n\npd/Max - Windows - Microsoft Visual C, Borland C++, MinGW:\n----------------------------------------------------------\nStart a command shell with your eventual build environment\n(e.g. run vcvars32.bat for Microsoft Visual Studio)\n\nthen run\n ..\\flext\\build.bat\n(you would have to substitute ..\\flext with the respective path to the flext package)\n\n\npd/Max - OSX/Linux - GCC:\n-------------------------\nFrom a shell run\nbash ../flext/build.sh\n(you would have to substitute ../flext with the respective path to the flext package)\n\n\n============================================================================\n\nVersion history:\n\n0.2 - changed methods for frequency scales: actually INCOMPATIBLE to version 0.1 \n\n0.1 - first release\n\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgrrrr%2Fconstantq","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fgrrrr%2Fconstantq","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fgrrrr%2Fconstantq/lists"}
