Makefile沒有鏈接.o文件

Question

提供了以下Makefile來編譯我的項目。 它似乎是用過時的風格編寫的，盡管我正在閱讀官方的GNU Make手冊，但無法對其進行修復。 該項目本身似乎正確編譯了所有.o文件，因為它在我的工作目錄中創建了所有這些文件：main.o model.o param.o

# //////////////// NOMBRE DEL PROYECTO /////////////////// 
#
P=project
#

EXE=$(P)
OBJS=main.o model.o param.o head.h

ADDLIBS=-D.
ADDINCFLAGS=-I.

SRCDIR=/root/projects/project

CXXFLAGS=-O3 -fomit-frame-pointer -pipe -DNDEBUG -pedantic-errors -Wparentheses -Wreturn-type -Wcast-qual -Wall -Wpointer-arith -Wwrite-strings -Wconversion -I$(COININCDIR)

`cat $(COINLIBDIR)/coinutils_addlibs.txt` 

# LIBS=-L$(COINLIBDIR) -lClp -lCoinUtils \
# -lm `cat $(COINLIBDIR)/coinutils_addlibs.txt`

INCL=-I`$(COININCDIR)`$(ADDINCFLAGS)



all: $(EXE)

.SUFFIXES: .cpp .c .o .obj

$(EXE): $(OBJS)
    bla=;
    for file in $(OBJS); do bla="$$bla ` $$file`"; done; \
    $(CXX) $(CXXLINKFLAGS) $(CXXFLAGS) -o $@ $$bla $(ADDLIBS) $(LIBS)   


.cpp.o:
    $(CXX) $(CXXFLAGS) $(INCL) -c -o $@ `test -f '$<' || echo '$(SRCDIR)/'`$<
.cpp.obj:
    $(CXX) $(CXXFLAGS) $(INCL) -c -o $@ `if test -f '$<'; then  '$<'; else '$(SRCDIR)/$<'; fi`
.c.o:
    $(CC) $(CFLAGS) $(INCL) -c -o $@ `test -f '$<' || echo '$(SRCDIR)/'`$<
.c.obj:
    $(CC) $(CFLAGS) $(INCL) -c -o $@ `if test -f '$<'; then '$<'; else '$(SRCDIR)/$<'; fi`

這是我收到的錯誤消息，盡管正如我所說，.o文件是在目錄中創建的，但是似乎找不到它們將它們鏈接到我的可執行文件中。

/bin/sh: 1: main.o: not found 
/bin/sh: 1: model.o: not found 
/bin/sh: 1: param.o: not found 
/bin/sh: 1: head.h: not found

Answer 1

在for循環中，以下位不正確。

` $$file`

這是不正確的，因為.o文件不是要為其輸出運行的可執行文件。

這個makefile非常糟糕，您是正確的。

與上述問題類似。

除非$(COININCDIR)是要運行的命令，否則此行是不正確的。

INCL=-I\`$(COININCDIR)\`$(ADDINCFLAGS)

此錯誤是/bin/sh: 1: /installed/CoinAll/include/coin: Permission denied錯誤。

另外，除非打算將$(ADDINCFLAGS)附加到$(COININCDIR)的值（幾乎肯定不是）上，否則兩個變量之間需要有一個空格。
