[Gnucap-devel] gnucap build with CMake on Windows

[Patrick Mulder]

Hello,

I thought I'd try a Windows build of Gnucap with CMake and MinGW32:


 cmake .. -G "Unix Makefiles" -DCMAKE_MAKE_PROGRAM=mingw32-make.exe
-- The C compiler identification is GNU 7.3.0
-- The CXX compiler identification is GNU 7.3.0

CMake Warning (dev) at CMakeLists.txt:33 (if):
  Policy CMP0064 is not set: Support new TEST if() operator.  Run "cmake
  --help-policy CMP0064" for policy details.  Use the cmake_policy command
to
  set the policy and suppress this warning.

  TEST will be interpreted as an operator when the policy is set to NEW.
  Since the policy is not set the OLD behavior will be used.
This warning is for project developers.  Use -Wno-dev to suppress it.

It works for the modelgen.exe and libgnucap.dll and then gives:

 38%] Building CXX object

[ 39%] Building CXX object

apps/CMakeFiles/gnucap-default-plugins.dir/all] Error 2
mingw32-make.exe: *** [Makefile:152: all] Error 2

I then tried to translate d_diode.model into a cc file manually and got:

 modelgen/gnucap-modelgen.exe
C:/Users/muld/git/gnucap/build4/modelgen/gnucap-modelgen.exe: error while
loading shared libraries: libgnucap.dll: cannot open shared object file: No
such file or directory

I think linking/loading the DLL is different on Windows/MSys then native
Linux.
Maybe someone here on the mailing list has more ideas what could be done to
make it work.

Thanks!

Patrick
