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:

```auto
$ 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

```auto
$ 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:

```auto
$ objdump -p my-binary.exe | less
...
The Import Tables (interpreted .idata section contents)
 vma: Hint Time Forward DLL First
                 Table Stamp Chain Name Thunk
 00483000 004830a0 00000000 00000000 00485570 00483a20

        DLL Name: ADVAPI32.dll
        vma: Hint/Ord Member-Name Bound-To
        4843a0 1195 CryptAcquireContextW
        4843b8 1197 CryptCreateHash
        4843ca 1198 CryptDecrypt

```

or

```auto
$ objdump -p mylibrary.dll | less
...
[Ordinal/Name Pointer] Table
        [0] getDomainStatus
        [1] utils_load
        [2] utils_unload

```
