Finding required dll's from Linux

Programming
1

It is possible to find which DLL files are needed for a windows binary or library in Linux.

To do this, you can use standard objdump utility if it supports PE format or you can install mingw cross compiler toolchains and run objdump within mingw:

$ objdump --private-headers my-binary.exe | grep "DLL Name"
	DLL Name: ADVAPI32.dll
	DLL Name: CRYPT32.dll
	DLL Name: KERNEL32.dll
	DLL Name: msvcrt.dll
	DLL Name: USER32.dll
	DLL Name: WS2_32.dll

or

$ sudo apt install mingw-w64
$ x86_64-w64-mingw32-objdump --private-headers my-binary.exe | grep "DLL Name"
	DLL Name: ADVAPI32.dll
	DLL Name: CRYPT32.dll
	DLL Name: KERNEL32.dll
	DLL Name: msvcrt.dll
	DLL Name: USER32.dll
	DLL Name: WS2_32.dll

You can also pipe output to a pager and look at the functions provided by a DLL or used within a binary from other DLL’s inside of Tables sections:

$ objdump -p my-binary.exe | less
...

or

$ objdump -p mylibrary.dll | less
