问题描述

我正在尝试使用 make -f makefile 制作文件,但我遇到了这个错误:

root@kevin-VirtualBox:/home/kevin/Desktop/makef# sudo -s make -f Makefile
gcc -c -o obj/main.o main.c -I./
make: execvp: gcc: Permission denied
make: *** [obj/main.o] Error 127

- 制作文件代码:

IDIR =./
CC=gcc
CFLAGS=-I$(IDIR)

ODIR=obj
LDIR =./

LIBS=-lgd -lrt

_DEPS = main.h Makefile
DEPS = $(patsubst %,$(IDIR)/%,$(_DEPS))

_OBJ = main.o serial.o fb.o menu_main.o timer.o cmdin.o buzzer.o statemachine.o inout.o network.o text_file_input.o text_file_input_oven.o
OBJ = $(patsubst %,$(ODIR)/%,$(_OBJ))


$(ODIR)/%.o: %.c $(DEPS)
    $(CC) -c -o $@ $< $(CFLAGS)

main: $(OBJ)
    gcc -o $@ $^ $(CFLAGS) $(LIBS)

.PHONY: clean

clean:
    rm -f $(ODIR)/*.o *~ core $(INCDIR)/*~

The problem is that you haven't installed the full Development tools. I encountered the same issue and solved it by installing the Development tools (including gcc)

yum groupinstall "Development Tools"
