Re: how to fix compile warning: cannot find entry symbol _ModuleEntryPoint

Thanks, Andrew, Laszlo and liming, with your help I find the module which really own the warning.

As the compile is multithreading, the order in compile log is not right. The module which cause warning is written by ourselves.
In this module's inf file, MODULE_TYPE is set as USER_DEFINED, and UefiDriverEntryPoint is not set in [LibraryClasses].

Wenyi,

If you look under the Build results   <Platform>/<DEBUG/RELEASE>_<COMPILER>/AArch64/Edk2/ArmPkg/Drivers/ArmGic/ (hopefully I got that right) and go down a little bit you will see the build generated GNUmakefile. You might want to take a look at that to try and figure out what is going on?

Thanks,

Andrew Fish

I checked my platform DSC and there's UefiDriverEntryPoint|MdePkg/Library/UefiDriverEntryPoint/UefiDriverEntryPoint.inf in the section [LibraryClasses.common].
I'm not sure why _ModuleEntryPoint can't be found when link the object.

Hi, all
I use edk2-stable201903 in my project and meet a compile warning like below,

/opt/buildtools/gcc-linaro-7.4.1-2019.02/aarch64-linux-gnu/bin/../lib/gcc/aarch64-linux-gnu/7.4.1/../../../../aarch64-linux-gnu/bin/ld: warning: cannot find entry symbol _ModuleEntryPoint; not setting start address

It seems like the warning happens when building EDKII/Edk2/ArmPkg/Drivers/ArmGic/ArmGicDxe.inf
does anyone know how to fix it?
If need more info, please contact me, thanks!

here's some of my build option, 
Architecture(s)  = AARCH64
Build target     = RELEASE
Toolchain        = GCC5
The UefiDriverEntryPoint lib class in the [Sources] section in
"ArmPkg/Drivers/ArmGic/ArmGicDxe.inf" should be resolved by your
platform DSC to
"MdePkg/Library/UefiDriverEntryPoint/UefiDriverEntryPoint.inf".

That's where the definition of _ModuleEntryPoint() should come from (see
"MdePkg/Library/UefiDriverEntryPoint/DriverEntryPoint.c").

Thanks
Laszlo
