Creating msvcrt.lib
# On Windows, within a VS developer prompt
# Dump the exports of msvcrt.dll
dumpbin.exe /exports C:\Windows\System32\msvcrt.dll > msvcrt.txt
# Copy msvcrt.txt to a Linux box
# Convert the file to Unix line endings
dos2unix msvcrt.txt
# Remove the header from dumpbin
sed -i '1,19d' msvcrt.txt
# Create msvcrt.def file and add the required "EXPORTS" line to the beginning
echo "EXPORTS" > msvcrt.def
# Get the list of functions and remove everything else, redirecting it to the .def file
awk '{print $4}' msvcrt.txt | sed '/^[[:space:]]*$/d' >> msvcrt.def
# Copy back to Windows in a developer prompt
# Create a .lib file from the .def file
lib.exe /def:msvcrt.def /out:msvcrt.lib /machine:x64
