I set up VS 2008 SP1 on Windows 7 (64-bit) and tried to build the psutil, got the following error. VS 2008 is properly setup and with SP1 successfully patched.
I ran the "python setup.py build" command per the INSTALL file in the package.

Any ideas which library is missing from the default distutils config? How can I successfully build psutil in my environment?
For the benefit of other people with the same problem: make sure to use the Visual Studio x64 command prompt for launching the setup script.

I have been trying to upgrade my POCO libraries to 1.9.0 which required me to upgrade SSL, which has changed some library names. I am using SSL (OpenSSL-Win64-110g) from Shining Light
I was able to recompile the new poco-1.9.0 libraries , including recompiling the Crypto and Net_SSL_Open_SSL in vs2015 pointing to the new SSL (110g) version.
In my project I reference the newly compiled POCO libs and referenced the new SSL lib paths.
The new SSL seems to have replaced ssleay32MT.lib and libeay32MT.lib with libcrypto64MT.dll and libssl64MT.dll, respectively, so I changed those references in my project as well.
When I compile I get 36 LNK2001 "Unresolved External Symbol" Errors associated with Net, NetSSL, and Crypto libraries. (listed below).
I am wondering it either the SSL 110g lib is too new for POCO 1.9, or needs to be compiled with VS2015. Not Sure though. Any ideas on things to check?

OK so I figured it out. the Crypto errors were because the settings I made in the POCO project linker didn't save; I noticed when running the compiler that the output of the linker didn't include the new SSL libraries (libcrypto.lib, libssl.lib) etc. I also was linking to static libraries in Crypto and Net_SSL.
On the PocoNET errors, I had to include ws2_32.lib and iphlpapi.lib in my linker add'l lib dependancies. I haven't had to do this in the past.
I hope this helps someone in a similar circumstance.
I'm compiling FFmpeg statically against VS2013 update 5 using --toolchain=msvc
If I link against avformat.lib i get a bunch of LNK2019 errors.
I can link make calls against the other libraries(avcodec, swscale, avutil).
Looking at the errors, it seems to be against all the networking .o's (tls_schannel.o, networking.o, tcp.o, etc....)

It's caused by missing Windows socket library when linking program.
If you don't want any network funcionality from ffmpeg just add this switch to configure command when building ffmpeg:
--disable-network
or if you want network add Ws2_32.lib to Additional dependecies in linker options in you program.

I am new to this and stuck with this problem for a while now. Any help would be much appreciated.
OPUS has multiple libs so make sure you link with all of them.
No idea what SDL2.lib is trying to find, but it seems to have built incorrectly or something. Even using the files provided on the website for SDL 2.0.3, i can't get my program to link because of the missing symbols.

Anyone have any idea why these functions can't be found, or why they even have _REAL at the end of them?
