BaseTools tools_def.template: Ignore link warning 4281 for VS2017

[edk2] [Patch] BaseTools tools_def.template: Ignore link warning 4281 for VS2017

Posted by Liming Gao 5 years, 10 months ago

VS2017 reports warning LNK4281: undesirable base address 0x0 for x64 image;
set base address above 4GB for best ASLR optimization.

edk2 build always sets baes address to zero as default. So, ignore this link
warning.
