I was trying to move over to DxeDebugPrintErrorLevelLib, but I can't
get it to build
For example I made DXE use
DebugPrintErrorLevelLib|MdeModulePkg/Library/DxeDebugPrintErrorLevelL
ib/DxeDebugPrintErrorLevelLib.inf in the EmulatorPkg and I get this error:
/Users/andrewfish/work/src/edk2/EmulatorPkg/EmulatorPkg.dsc(...):
error F002: Library
[/Users/andrewfish/work/src/edk2/MdePkg/Library/UefiBootServicesTable
Lib/UefiBootServicesTableLib.inf] with constructors has a cycle
consumed by
/Users/andrewfish/work/src/edk2/MdePkg/Library/UefiLib/UefiLib.inf
The error message is not very helpful on root causing the issue....
But a circular constructor issue does not seem that strange in the
DebugLib stack as everything uses that! If I go into
DxeDebugPrintErrorLevelLib.inf and remove the HobLib I don't get the
Constructor error, but I do get a link error.
So it looks like the DxeDebugPrintErrorLevelLib depends on the Hob
lib that depends on the DebugLib that depends on the
DxeDebugPrintErrorLevelLib. How did this every work? The only place I see it
used is the Nt32Pkg, and I don't have a system to test that on????
Just tried NT32 with VS2015, and it builds and works well.
Liming & Yonghong, any idea on this?
I was wondering if it had to do with the lower level libraries having a
constructor? So maybe library implementation matters?
If this circular constructor issue could be reproduced with only one
module linked with DxeDebugPrintErrorLevelLib (I mean other modules to
link with BaseDebugPrintErrorLevelLib, only the module links to
DxeDebugPrintErrorLevelLib), then that may be helpful to scrub all the library
instances the module links to find out what is the matter. :)
OK in the EmulatorPkg the DXE Core compiles, but
MdeModulePkg/Universal/StatusCodeHandler/RuntimeDxe/StatusCodeHan
dlerRuntimeDxe.inf will error out.
I think it is as simple as you can't have a library with a constructor required
by
the DebugLib (and child libraries) for a library that depends on the DebugLib.
So the chain to get the DebugLib started depends on the DebugLib.
That kind of makes DxeDebugPrintErrorLevelLib hard to use I guess?
Thanks,
Andrew Fish

It looks like a HOB lib with the constructor is what triggers the issue?
