问题
I am having some issues with a makefile I am creating for a school project. I am compiling and assembling a C file and a SPARC assembly file (respectively) and linking them. I'm working in a Unix environment. Here is the makefile:
proj09.exe: proj09.driver.o proj09.support.o
<tab>gcc -Wall proj09.driver.o proj09.support.o -o proj09.exe
proj09.driver.o: proj09.driver.c /user/cse320/Projects/project09.support.h
<tab>gcc -Wall -c proj09.driver.c /user/cse320/Projects/project09.support.h
proj09.support.o: proj09.support.s
<tab>gcc -Wall proj09.support.s
When I try to make it, though, I get a reader error, specifically:
"Fatal error in reader: proj09.makefile, line 2: Unexpected end of line seen"
Now I know that usually this means that something is formatted incorrectly, but I have no idea what it could be in this case. Also, I am not 100% sure that this is the correct code for the makefile (specifically the assembling of my support.s file, and the linking of both files). I apologize if this is a repeat question, I looked through the archives beforehand and couldn't find anything of use. Any help would be greatly appreciated!
EDIT: I don't see why this would make a difference, but I am using gedit to actually write the code and then transferring the files into SSH for linking.
回答1:
As Joachim told you, the lines should be indented by tab, not by spaces, so the second line should look like:
[TAB]gcc -Wall proj09.driver.o proj09.support.o -o proj09.exe[NEWLINE]
where [TAB] means TAB character.
Also there shouldn't be any spaces after the command. That's why I've put [NEWLINE] char.
回答2:
Aside from the spaces and tabs, this doesn't generate an object file, shouldn't even compile (unless it has main()):
gcc -Wall proj09.support.s
You should use -c here too:
gcc -Wall -c proj09.support.s
Note: if you're working on Unix/Linux lose the .exe
