我正在尝试在 Windows 上使用 MYSYS2 GCC 11.2.0 在某个位置静态链接库。
这是我的 makefile：（从 M.M 编辑 1 和 n.1.8e9-where's-my-share m。）
#changed .o to .so, ty "n. 1.8e9-where's-my-share m."
libmxn_external_test.so: mxn_external_test.h mxn_external_test.c
gcc -o libmxn_external_test.so -fpic -shared mxn_external_test.h mxn_external_test.c
#changed .o to .so
libmxn_external_test.a: libmxn_external_test.so
ar rcs C:\libs\c\libmxn_external_test.a libmxn_external_test.so -v
#changed main to main.c, ty "M.M"
main.o: main.c
gcc -c main.c
main: main.o
gcc main.o -LC:\libs\c -lmxn_external_test -o main
#this kinda works but after graduating with a CS degree, and a few hours of make videos, haven't figured out much more yet
quick: main.o libmxn_external_test.so
gcc -o main main.o libmxn_external_test.o
clean:
rm libmxn_external_test.h.gch libmxn_external_test.so main.o
我在运行“make main”时收到此错误：
