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/DxeDebugPrintErrorLevelLib/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/UefiBootServicesTableLib/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. :)
