-ldl and -lcygwin should not be used when you compile with the mingw toolchain: these would lead to a executable that is not pure Windows. These might be pulled in by some dependencies compiled with the cygwin compile - you should remove these dependencies (or compile them with the mingw toolchain). > as identified in the following: > > johnf@INSPI13 /cygdrive/c/gmsh/build > > $ make > Scanning dependencies of target gmsh > [ 0%] Building CXX object CMakeFiles/gmsh.dir/Fltk/Main.cpp.o > [ 0%] Building CXX object CMakeFiles/gmsh.dir/Common/GmshGlobal.cpp.o > --- > ---- > [ 99%] Building C object > CMakeFiles/gmsh.dir/contrib/mmg3d/build/sources/analarcutting.c.o > [ 99%] Building C object > CMakeFiles/gmsh.dir/contrib/mmg3d/build/sources/analar.c.o > [100%] Linking CXX executable gmsh.exe > /usr/lib/gcc/x86_64-w64-mingw32/6.4.0/../../../../x86_64-w64-mingw32/bin/ld: > cannot find -ldl > /usr/lib/gcc/x86_64-w64-mingw32/6.4.0/../../../../x86_64-w64-mingw32/bin/ld: > cannot find -ldl > /usr/lib/gcc/x86_64-w64-mingw32/6.4.0/../../../../x86_64-w64-mingw32/bin/ld: > cannot find -lcygwin > collect2: error: ld returned 1 exit status > make[2]: *** [CMakeFiles/gmsh.dir/build.make:18362: gmsh.exe] Error 1 > make[1]: *** [CMakeFiles/Makefile2:420: CMakeFiles/gmsh.dir/all] Error 2 > make: *** [Makefile:161: all] Error 2 > > Thank you again for any hints/assistance. > > John > > On Thu, Feb 22, 2018 at 3:29 AM, Christophe Geuzaine <cgeuza...@uliege.be > <mailto:cgeuza...@uliege.be>> wrote: > > >> On 19 Feb 2018, at 04:20, John Staples <john.f.stap...@gmail.com >> <mailto:john.f.stap...@gmail.com>> wrote: >> >> Greetings All, >> >> Thank you for any help with the following: >> >> On Windows10, I've successfully installed CYGWIN 64bit shell >> (https://cygwin.com/install.html <https://cygwin.com/install.html>) with >> FLTK, OPENGL, BLAS, LAPACK, etc..
