I am trying to link glew32.lib in vc++ and I am getting unresolved externals. I set show progress to verbose to see what was happening and I get this output:
...
Referenced in OpenGL32.lib(OPENGL32.dll)
Loaded OpenGL32.lib(OPENGL32.dll)
Searching C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\lib\glew32.lib:
Searching C:\Program Files (x86)\Windows Kits\8.0\lib\win8\um\x86\kernel32.lib:
Found _imp_GetLastError#0
Referenced in main.obj
...
So it looks to me like its just skipping the .lib entirely? At the end of the output it tells me that glew32.lib is unused. I'm including the header, and getting no errors other than the unresolved externals. Why is it skipping over linking this file?

Trying to compile a VC++ DLL I get some error messages related to Visual Studio cannot resolve external symbols, errors LNK2001, LNK1120.
In my case the symbol it cannot be resolved is: __imp__BCryptGenRandom#16
and the error message is:
error LNK2001: unresolved external symbol __imp__BCryptGenRandom#16
I have googled and found that it is said to link BCrypt.lib so I have linked it at "properties->linker->input->additional dependency"
Also at ""properties->linker->all options->additional library directoris" I have added below one where BCrypt.lib is for x86:
C:\Program Files (x86)\Windows Kits\10\Lib\10.0.19041.0\um\x86
And finally at "properties->linker->General->Use library dependencies inputs" I have set "Yes".
But none of these methods work.
So I am on:
Windows 10
MS Visual Studio 2017 (2017 build tools)
trying to build:
qt5.10.1 with QtWebEngine
using jom.exe -j4
and during the QtWebEngine build process, this happened:

I found this forum with a slightly active/recent question asking about this same issue here:
Internal compiler error in outdname.c in VS15.7p3 when building Firefox webrtc code
Is there anything I can do from this point to fix this?
Downgrading my version of VS to 2015 allowed me to bypass this compiler error and compile QT successfully.
I am working with visual studio 2012 to compile LuaJava. The problem I am having is when I call the linker. The line that calls the linker in the makefile is:
link /dll /LIBPATH:"C:\Program Files (x86)\Microsoft SDKs\Windows\v7.1A\Lib\x64"
/LIBPATH:"C:\Program Files (x86)\Microsoft Visual Studio 11.0\VC\lib\amd64"
/out:luajava-1.1.dll src\c\luajava.obj
"C:\Program Files (x86)\Lua\5.1\lib\lua5.1.lib" /VERBOSE
This seems to almost be linking everything successfully, until it gets to the Lua library.
The linker outputs the following when I try to make the project:
...//linking of other libraries
Finished searching libraries
Unused libraries:

Stop.
I'm confused as to why it says that the Lua library is unused, and then complains when it can't find the Lua library functions.
You can not link a 32 bit library to your 64 bit application. After some searces I do not believe LuaJava has a x64 download so to use this you must change your application to 32 bit.
Edit:
A second method would be to recomile LuaJava as a 64 bit dll. Here is a very recent post about that: LuaJava compile error "Unresolved external symbol"
Is there a smart way to find the relevant places in the code when you get warnings like this? It seems the only line number shown refers to standard headers but not the actual code. I must add that the project is very large with hundreds of modules and 1MLOC+.

Your code has no problems.
But unfortunately, the code in VC standard headers is not warning-free in level 4. You can only disable that warning using the compiler option.
I just finished my project and tried building it in Release for the first time. I've had previous issues with the Windows 7 SDK and the Common7 stuff located in program files(ie they were missing and I had to install them from msdn).
The build is complaining :
1>LINK : fatal error C1350: error loading dll 'msobj110.dll': dll not found
1>Block.obj : fatal error LNK1000: unknown error at 00A14372; consult documentation for technical support options
========== Rebuild All: 0 succeeded, 1 failed, 0 skipped ==========
Yet I looked at :
C:\Program Files (x86)\Microsoft Visual Studio 11.0\Common7\IDE
I have the same folder under C:\Program Files..., and IDE is almost empty; doesn't have the ms libraries.
How can I know where Visual Studio picks these dll from? I'm using VS2012.
