How to crosscompile C, C++ and assebly source file from Linux-64bit to Windows-32it?

Question

I have the following files in my project:

• file.s and STR_ARR.s as x86 assembly source files.
• file.c and main.c as C source files.
• directoryListing.cpp as C++ source files.

I am working on a 64 bit distribution of arch and I need to compile these file both for linux and windows 32 bit. Right now the linux part of the project works fine, this is my makefile:

C_OPTIONS = -m32 -fPIC


build-elf: STR_ARR.elf.o directoryListing.elf.o main.elf.o file.s.elf.o file.elf.o
    $(CC) $(C_OPTIONS) STR_ARR.elf.o directoryListing.elf.o file.s.elf.o file.elf.o main.elf.o -o $(OUTPUT_DIR)/$(elfC_NAME).elf -static -lstdc++

main.elf.o: main.c
    $(CC) $(C_OPTIONS) -c main.c -o main.elf.o

directoryListing.elf.o: directoryListing.cpp directoryListing.hpp
    $(CXX) $(C_OPTIONS) -std=c++17 -c directoryListing.cpp -o directoryListing.elf.o

STR_ARR.elf.o: STR_ARR.s STR_ARR.h
    $(CC) $(C_OPTIONS) -c STR_ARR.s -o STR_ARR.elf.o

file.elf.o: file.c file.h
    $(CC) $(C_OPTIONS) -c file.c -o file.elf.o

file.s.elf.o: file.s file.s.h
    $(CC) $(C_OPTIONS) -c file.s -o file.s.elf.o

I am trying to cross compile the project using mingw32 and this make file:

CXX_WIN = i686-w64-mingw32-g++
CC_WIN = i686-w64-mingw32-gcc
C_OPTIONS = -m32 -fPIC


build-exe: STR_ARR.exe.o directoryListing.exe.o main.exe.o file.s.exe.o file.exe.o
    $(CC_WIN) $(C_OPTIONS) STR_ARR.exe.o directoryListing.exe.o file.s.exe.o file.exe.o main.exe.o -o $(OUTPUT_DIR)/$(exeC_NAME).exe -static -lstdc++

main.exe.o: main.c
    $(CC_WIN) $(C_OPTIONS) -c main.c -o main.exe.o

directoryListing.exe.o: directoryListing.cpp directoryListing.hpp
    $(CXX_WIN) $(C_OPTIONS) -std=c++17 -c directoryListing.cpp -o directoryListing.exe.o

STR_ARR.exe.o: STR_ARR.s STR_ARR.h
    $(CC_WIN) $(C_OPTIONS) -c STR_ARR.s -o STR_ARR.exe.o

file.exe.o: file.c file.h
    $(CC_WIN) $(C_OPTIONS) -c file.c -o file.exe.o

file.s.exe.o: file.s file.s.h
    $(CC_WIN) $(C_OPTIONS) -c file.s -o file.s.exe.o

But no matter what I do the linker seems to be unable to find the libc functions and the SA_* functions in STR_ARR.s.

I have tried building a shared library, explicitly linking -lc and and -lcrt and reinstalling mingw but nothing seems to work.

Here's the output of calling make:

$ make build-exe
