Link error with static version of zlib?




Hello,

I am trying to produce an executable using mingw that uses all-static
linking, that is, that it does not rely on any DLLs except possibly
the Microsoft msvcrt.dll

Is it possible?

If I am not mistaken, when selecting the package mingw64-x86_64-zlib
with the installer, it installs the library, which has been compiled
as both a DLL and a static library.

But it appears that the minizip library included within the zlib
package is only present in DLL form.

When building, I get the following

make
x86_64-w64-mingw32-g++ -O2 -fno-strength-reduce -O2
-fno-strength-reduce -g
-I/usr/x86_64-w64-mingw32/sys-root/mingw/include/     -DDEBUG -D_WIN32
 -std=c++11   -c -o main.o main.cpp
x86_64-w64-mingw32-g++ -o app.exe -O2 -fno-strength-reduce -g -Wall
-Wpointer-arith -L/usr/lib main.o -mwindows -static -lws2_32 -lgdi32
-lcomctl32 -lcomdlg32 -lminizip -lz
-Wl,--enable-auto-import,--enable-runtime-pseudo-reloc
/usr/lib/gcc/x86_64-w64-mingw32/5.4.0/../../../../x86_64-w64-mingw32/bin/ld:
cannot find -lminizip
collect2: error: ld returned 1 exit status


But yet, when I build the with the exact same command on linux, I get
an executable and it depends only on msvcrt.dll (and comctl32.dll,
comdlg32.dll, kernel32.dll, user32.dll and ws2_32.dll, obviously).

If I modify the link line to instead link -lminizip.dll, I get the
following errors

/usr/lib/libpthread.a(t-d001060.o):fake:(.text+0x2): undefined

Is there a proper way of getting the minizip lib statically-compiled?

Thank you
