I now made the corresponding changes, so that plstdio.c compiles and links for Visual C++ (2008). I have not tested the function though if it works. > > > Could you verify that I have the right type (int) for the variable > flags? Also, on Windows with mingw32 I'm getting the following warning > message: > > [ 9%] Building C object src/CMakeFiles/plplotd.dir/plstdio.c.obj > C:\users\hazen\plplot\src\plstdio.c:206:1: warning: "_S_IREAD" > redefined > In file included from C:\users\hazen\plplot\src\plstdio.c:31: > C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/sys/stat.h: > 39:1: > warning: this is the location of the previous definition > C:\users\hazen\plplot\src\plstdio.c:207:1: warning: "_S_IWRITE" > redefined > C:/MinGW/bin/../lib/gcc/mingw32/3.4.5/../../../../include/sys/stat.h: > 38:1: > warning: this is the location of the previous definition > [ 10%] Building C object src/CMakeFiles/plplotd.dir/plstripc.c.obj I changed the code, so that _S_IREAD and _S_IWRITE are only defined if undefined. This removes the warnings (also for MinGW I assume), but I consider this code "suboptimal".
