如何解决如何将 C、C++ 和 assebly 源文件从 Linux-64 位交叉编译到 Windows-32it？
我的项目中有以下文件：
-
file.s和STR_ARR.s作为 x86 汇编源文件。 -
file.c和main.c作为 C 源文件。 -
directoryListing.cpp作为 C++ 源文件。
我正在开发 64 位的 arch 发行版，我需要为 linux 和 windows 32 位编译这些文件。现在项目的 linux 部分工作正常，这是我的 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
我正在尝试使用 mingw32 和这个 make 文件交叉编译项目：
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
但是无论我做什么，链接器似乎都无法在 SA_* 中找到 libc 函数和 STR_ARR.s 函数。
我尝试构建共享库，明确链接 -lc 和 -lcrt 并重新安装 mingw，但似乎没有任何效果。
这是调用 make 的输出：
$ make build-exe
i686-w64-mingw32-gcc -m32 -fPIC -c STR_ARR.s -o STR_ARR.exe.o
i686-w64-mingw32-g++ -m32 -fPIC -std=c++17 -c directoryListing.cpp -o directoryListing.exe.o
i686-w64-mingw32-gcc -m32 -fPIC -c main.c -o main.exe.o
i686-w64-mingw32-gcc -m32 -fPIC -c file.s -o file.s.exe.o
