Problem Running Tests with Readline Library in C

[rohan-mehta-1024]

Hello I am having an issue trying to run the first test (my implementation is in C). I have created the following makefile which works when I run "make" in the directory of my implementation:

program: step0_repl.c
gcc -ledit step0_repl.c

But when I try to run the first test, it gives this error (there is some problem with the readline library?):

/Applications/Xcode.app/Contents/Developer/usr/bin/make -C impls/c step0_repl
cc step0_repl.c -o step0_repl
Undefined symbols for architecture x86_64:
"_readline", referenced from:
_main in step0_repl-dcb634.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make[1]: *** [step0_repl] Error 1
make: *** [impls/c/step0_repl] Error 2

I am very new to C and so don't understand what's going on. Apologies if this is an obvious question.

Hi @rohan-mehta-1024 , try adding -lreadline as another argument to your cc line.

Hello @dubek, unfortunately this returns the same error message. Also, that cc line is what is run internally by the "text^quux^step0_repl" command - is there any way for me to get it to work by just running this command with some other argument? The thing I find confusing is when I just run make in the implementation directory, it compiles fine, but it's not able to compile when I try to run the tests.

Actually, now if I compile it first by running make in the implementation directory and then trying to run make "text^quux^step0_repl" at the top level, I get this error:

/Applications/Xcode.app/Contents/Developer/usr/bin/make -C impls/c step0_repl
make[1]: `step0_repl' is up to date.

Any ideas?

I have since fixed the issue, thanks! (I had to add executable permissions to my run script?)
