Hi Walt, Are you using the Cygwin version of CMake? I am not sure what the differences are, but I know there are some (possibly just the makefile generator …). I see you are using the Visual Studio generator – I am not sure that is a good idea in combination with Cygwin. The reason for that is that for some platforms (Cygwin and MinGW-w64/MSYS2) on Windows a bash shell is used and for “bare” Windows it is not. CMake tries to hide these platform issues as much as possible, but that does not mean (unfortunately) that you can use any combination 😉.
With a fairly recent version of gfortran you should be able to build PLplot. Some further comments below.

I always learn something from you. However, I still can't get where I want. >>AM: you make me blush 😊. With the plplot that comes with Msys2, execution hangs awaiting input. If I type "1", it produces output on the screen. Also -dev works (Arjen). Trying to build plplot with msys produces similar (or worse) results. >>AM: nastiness with buffering of output to the screen, sigh. Trying build with cygwin, cmake produces the following lines multiple times. $ "/cygdrive/c/Program Files/Cmake/bin/cmake.exe" -DCMAKE_INSTALL_PREFIX=install -DENABLE_cxx=OFF -DENABLE_cxx=OFF -DENABLE_qt=OFF ../plplot.git >& cmake.out -- Configuring done CMake Error in bindings/fortran/CMakeLists.txt: Evaluation file to be written multiple times with different content. This is generally caused by the content evaluating the configuration type, language, or location of object files: C:/walt/Software/Plplot/BUILD/bindings/fortran/plplotfortran_ifort.def.sh<https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fplplotfortran_ifort.def.sh&data=02%7C01%7C%7C15270ecebb7e4a6cba7908d78fd07610%7C15f3fe0ed7124981bc7cfe949af215bb%7C0%7C0%7C637135997820643311&sdata=fI0JAP1SzRf2stUr6gfPjsjGGo2gnwbXcYZnNMcZ2nk%3D&reserved=0> I am using the latest cmake (3.16.2) and the latest plplot. cygwin does not have the latest Fortran compiler, but that shouldn't be a problem, should it? cmake.out is attached. Any help would be appreciated. OW, I will just use the flaky msys plplot. Thanks. >>AM: I strongly suspect this is because of the mixture of platforms. Try: * CMake for Cygwin (according to Cygwin’s setup: the current version is 3.14.5-1) * Use the generator options -G "Unix Makefiles" (this is the appropriate generator for Cygwin) * Cygwin has gcc/gfortran 7.4.0-1, that is certainly recent enough -- Walt Brainerd DISCLAIMER: This message is intended exclusively for the addressee(s) and may contain confidential and privileged information.
