LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'

[bMac244]

Whenever I try to configure FFMPEG, is gives me "cl.exe is unable to create an executable file." and shows "LINK : fatal error LNK1104: cannot open file 'LIBCMT.lib'" in the log file, even though I'm pointing to it when I type "echo $LIB". I don't know why it can't see the .LIB files.

@bMac244 Hello!

Yesterday I ran into the same problem. In my case I didn't enable x64 hosted MSVC toolset, running x64 Native Tools Command Prompt for VS 20xx shortcut before opening mingw64.exe terminal.

Did you do that?

FYI, How to: Enable a 64-Bit, x64 hosted MSVC toolset on the command line Use the Microsoft C++ toolset from the command line

Hi, sorry for the late reply.

I tried that before posting (as evident by the echo $LIB result) and it didn't work. I also found out that FFmpeg already integrated NVEC into the regular version so this whole thing is now unnecessary.

Thanks for the input though.
