Dear Keith, Many thanks for your detailed reply. I guess I will just have to look for other avenues to create the Windows shared library perhaps by building on the target Windows platform if cross-compilation is not an option. Being just one man and a dog, I do not want to get mired down in having to have to learn a whole different IDE world such as Visual Studio so perhaps there something I can explore with the Linux subsystem that ships with Windows 10? Thanks again for your comments. -- Michael Ellis September 4, 2020 5:16 PM, "Keith Marshall" <keith****@users*****> wrote: > On 04/09/2020 14:28, Michael Ellis wrote: > >> What exactly is illegal? > > "mingw" (irrespective of any capitalization) is a US registered > trademark (reg. no. 86017856); it has been registered by SPI Inc., on > behalf of MinGW.org, and no other project, or organization, is legally > entitled to use the term "mingw" within their project or product names, > without seeking authorization from MinGW.org (which none have). > >> Is it the x86_64-w64-mingw32-g++ cross compiler that I am using on my >> OS-X computer? > > The product name infringes the trademark. > >> I downloaded this using the "brew install mingw-w64" Is this program >> illegal? > > Once again, "mingw-w64" infringes the trademark. > >> If so, is there a legal cross compiler allowing me to build on OS-X >> and deeply on Windows? > > The only binaries, legally published by MinGW.org, are for a 32-bit > natively hosted Windows-32 GCC compiler suite; it simply isn't practical > for us to maintain binary releases, to support a plethora of non-Windows > cross-compiler platforms. > > That said, I do build my own mingw32 cross-compiler, for use on my Linux > hosts, and my build specs are included in the (modified) source tarball, > as published in MinGW.org FRS.
