Question

好的，我已经尽可能多地尝试了（不太了解递归制作）。所以希望有人能够对这个问题有所了解。这是我的目录结构列表...

SAB->
   -- Makefile
   -- Readme.txt
   -- bin -> Empty
   -- obj -> Empty
   -- src -> Another makefile in here with c sources
      |--> transfer -> Another makefile in here with sources
      |--> prs_socket -> Another makefile in here with sources

下面是有问题的品牌，下面是另一个品牌文件。来自prs_socket目录的那个。后者Makefile并没有将-fPIC开关放在那里。

# S.A.B. project main makefile

CC=gcc
CFLAGS=-std=c99 -Wall -Wextra -pedantic
LDFLAGS=

MAKEFILE = Makefile
TARGETS = build

all: $(TARGETS)

.PHONY: build clean install uninstall
build:
    @echo Building S.A.B.
    cd src && make
    cd src/transfer && make
    cd src/prs_socket && make
    cd src/prs_socket/tests && make

clean:
    @echo Cleaning project...
    @rm -f *~
    cd src/prs_socket && make clean
    cd src/prs_socket/tests && make clean
    cd src/transfer && make clean
    cd src && make clean
    @echo Done cleaning!

install:
    @echo Installing... S.A.B.
    cd src/prs_socket && make install
    cd src/transfer && make install
    cd src && make install
    @echo Done installing!

uninstall:
    @echo Uninstalling... S.A.B.
    cd src/prs_socket && make uninstall
    cd src/transfer && make uninstall
    cd src && make uninstall
    @echo Done uninstalling!

这是prs_socket目录的makefile，它不像它应该放置-fPIC。

CC=gcc
CFLAGS+=-fPIC
LDFLAGS=-shared -fPIC -Wl,-soname,libprs_socket.so.1 -lc

TARGET=libprs_socket.so.1.0
BINDIR=../../bin
OBJDIR=../../obj
SRCDIR=../../src
INSTALLDIR?=/opt
SOURCES = $(wildcard $(SRCDIR)/prs_socket/*.c)
INCLUDES = $(wildcard $(SRCDIR)/prs_socket/*.h)
OBJECTS = $(SOURCES:$(SRCDIR)/prs_socket/%.c=$(OBJDIR)/%.c.o)

all: linux

linux: $(BINDIR)/$(TARGET)

$(BINDIR)/$(TARGET): $(OBJECTS)
    @$(CC) $(CFLAGS) $(LDFLAGS) -o $@ $^

$(OBJECTS) : $(OBJDIR)/%.c.o: $(SOURCES)
    @$(CC) $(CFLAGS) -c -o $@ $<

.PHONY: clean install uninstall
clean:
    @echo Cleaning up...
    @rm -f *~ $(OBJDIR)/*.c.o $(BINDIR)/$(TARGET)
    @echo Done cleaning!

install:
    @echo Installing...
    @mkdir -p $(INSTALLDIR)/include/prs_socket
    @cp $(SRCDIR)/prs_socket/socket.h $(INSTALLDIR)/include/socket.h
    @cp $(BINDIR)/$(TARGET) $(INSTALLDIR)/lib
    @ln -sf $(INSTALLDIR)/lib/$(TARGET) $(INSTALLDIR)/lib/$(TARGET).1
    @ln -sf $(INSTALLDIR)/lib/$(TARGET) $(INSTALLDIR)/lib/libprs_socket.so
    @chmod 0755 $(INSTALLDIR)/lib/$(TARGET)
    @chmod 0755 $(INSTALLDIR)/lib/libprs_socket.so.1
    @chmod 0755 $(INSTALLDIR)/lib/libprs_socket.so
    @echo Install finished!

uninstall:
    @echo Uninstalling...
    @rm -rf $(INSTALLDIR)/include/prs_socket
    @rm -f $(INSTALLDIR)/lib/libprs_socket.so.1
    @rm -f $(INSTALLDIR)/lib/libprs_socket.so
    @rm -f $(INSTALLDIR)/lib/$(TARGET)
    @echo Uninstall finished.

更新：以下是运行make后显示的内容，删除@。
