Using static libraries:

  gcc -o sample.exe sample.c -I../../../include -L../../../lib/mingw4_64 -liup -lkernel32 -luser32 -lgdi32 -lwinspool -lcomdlg32 -ladvapi32 -lshell32 -lole32 -loleaut32 -luuid -lcomctl32

Using dynamic libraries:

  gcc -o sample.exe sample.c -I../../../include -L../../../lib/dllw4_64 -liup

Using dynamic libraries with no console:

  gcc -Wl,-subsystem,windows -o sample.exe sample.c -I../../../include -L../../../lib/dllw4_64 -liupstub -liup

Adding a resource file:

  windres -D TEC_64 -O coff -o iup.res ../../../etc/iup.rc
  gcc -Wl,-subsystem,windows -o sample.exe sample.c iup.res -I../../../include -L../../../lib/dllw4_64 -liupstub -liup
