DEBUG() does work in the debug version. It does not work in the release version. > so I chang MdePkg/Include/Library/DebugLib.h : as > below: > Origin: > #if !defined(MDEPKG_NDEBUG) > #define DEBUG(Expression) \ > do { \ > if (DebugPrintEnabled ()) { \ > _DEBUG (Expression); \ > After change: > #if 1 > #define DEBUG(Expression) \ > do { \ > if (DebugPrintEnabled ()) { \ > _DEBUG (Expression); \ If, for some reason you really want debug enabled in the RELEASE build, then you should modify OvmfPkg/OvmfPkgX64.dsc to not set MDEPKG_NDEBUG. But, I don't think you really want to do this. > Then build with command line : build.sh -a x64 -b RELEASE -n 20 Why not instead build with -b DEBUG? Then when you run QEMU, add these parameters: -debugcon file:debug.log -global isa-debugcon.iobase=0x402 Then after running QEMU, examine the debug.log file to see the debug messages.
