For the time being, I am stil working on maintaining
MinGW32 Linux Distro. We have now more than 200 packages.
But if I write this ticket tonight this is because I discovered this usage from objdump with its flag -p while I was on the Internet tonight.
That gave me the idea to write a quick function
david@amdgaming:~$ cat Get_Required_DLL.Sh
_get_missing_dll_at_runtime ()
{
my_file="${1}"
local my_path="/opt/MinGW32/i686-w64-mingw32/bin"
[ ! -f "${my_file}" ] && { echo "not a regular file!"; exit 1; }
for file in $(objdump -p ${my_file} |grep "DLL Name"|awk '{print $NF}'|sort);
do
[ -f "${my_path}/${file}" ] && echo "${my_path}/${file}" || echo "# not found: ${file}";
done
}
So here I just need to source this file
source Get_Required_DLL.Sh
Here are some examples
- Looking for required DLLs for
upx.exe
david@amdgaming:~$ _get_missing_dll_at_runtime /opt/MinGW32/i686-w64-mingw32/bin/upx.exe
# not found: KERNEL32.dll
/opt/MinGW32/i686-w64-mingw32/bin/libstdc++-6.dll
/opt/MinGW32/i686-w64-mingw32/bin/libucl-1.dll
/opt/MinGW32/i686-w64-mingw32/bin/libwinpthread-1.dll
# not found: msvcrt.dll
# not found: USER32.dll
/opt/MinGW32/i686-w64-mingw32/bin/zlib1.dll
- Looking for required DLLs for
mediainfo.exe
david@amdgaming:~$ _get_missing_dll_at_runtime /opt/MinGW32/i686-w64-mingw32/bin/mediainfo.exe
# not found: KERNEL32.dll
/opt/MinGW32/i686-w64-mingw32/bin/libgcc_s_sjlj-1.dll
/opt/MinGW32/i686-w64-mingw32/bin/libstdc++-6.dll
# not found: msvcrt.dll
# not found: SHELL32.dll
/opt/MinGW32/i686-w64-mingw32/bin/zlib1.dll
- Looking for required DLLs for
ocspcheck.exe
david@amdgaming:~$ _get_missing_dll_at_runtime /opt/MinGW32/i686-w64-mingw32/bin/ocspcheck.exe
# not found: KERNEL32.dll
/opt/MinGW32/i686-w64-mingw32/bin/libcrypto-42.dll
/opt/MinGW32/i686-w64-mingw32/bin/libssp-0.dll
/opt/MinGW32/i686-w64-mingw32/bin/libtls-16.dll
# not found: msvcrt.dll
# not found: WS2_32.dll
That's a pretty cool function and should make life easier. Later if I want to share some packages then I just need to compress them using upx.exe through wine (I have upx.exe installed in my toolchain)
wineconsole --backend=curses upx.exe --best --strip-relocs=0 *.dll *.exe
Of course there might be some exceptions and some tests need to be performed after that step before sharing any package.
I've recently used my own MinGW32 Linux Toolchain to generate a quick build for MPV Player for win32
