RE: [Vxl-users] Cygwin / mingw build problems

[Wheeler, F. W \(Research\) <wh...@cr...>]

Stefan,

I have a Cygwin/MinGW build on the VXL dashboard.  It has been working =
for a couple of years, through several cygwin tool upgrades.  Take a =
look at the build notes (the icon next to the Build Name on the =
dashboard) to see the CMakeCache settings I used and the various tool =
versions.  It's basically an up-to-date Cygwin installation.  You wrote =
"CXX_FLAGS and CC_FLAGS".  Do you mean "CXX_FLAGS and C_FLAGS" -- with =
"C" instead of "CC"?  Maybe your config got messed up because .c files =
were not compiled with -mno-cygwin?  For CMake I set

CMAKE_C_FLAGS:STRING=3D-mno-cygwin -Wall -O2 -g
CMAKE_CXX_FLAGS:STRING=3D-mno-cygwin -Wall -O2 -g

I have not compiled VXL in the MinGW environment, just in Cygwin with =
-mno-cygwin.
