error on make; editline/readline.h: no such file or directory

[smlavine]

Hello. When I try to make the program, an error shows that editline/readline/h does not exist.

`[ 40%] Built target libbrainfuck_static [ 60%] Building C object CMakeFiles/brainfuck.dir/src/main.c.o /media/sebastian/UUI/sml/Coding/BF/brainfuck/src/main.c:24:11: fatal error: editline/readline.h: No such file or directory

I have libedit in a directory in my home directory, and I have the dependencies required for that as well. Am I doing something wrong?

[fabianishere]

Hi! Are you sure the header files of libedit are on your include path?

What platform are you using exactly and how do you have the libedit library installed?

[smlavine]

Currently, the compiler is in /media/sebastian/UUI/sml/Coding/BF/brainfuck, with the build directory in the brainfuck directory. The libedit directory is in /home/sebastian. I am on Ubuntu 17.10.

[fabianishere]

Does it build if you install libedit (e.g. sudo apt-get install libedit-dev)?

[smlavine]

It built, but the command "brainfuck" doesn't work, even in the right directory.

[fabianishere]

In the build directory, you should invoke it by ./brainfuck instead of just brainfuck.

[smlavine]

Permission is denied. I have done chmod +x brainfuck, but it still won't work.

Could you verify that the brainfuck file is an ELF binary (file ./brainfuck) and you have execute permissions for the binary (ls -la ./brainfuck)?

[smlavine]

It is an ELF, but I do not have execute permissions. It's really weird, even when I do chmod +x brainfuck, it doesn't change, and even changing it through Nautilus and selecting properties, it will uncheck the box when I check it, or change any other properties. It seems I don't have any permissions for it, even in root.

[fabianishere]

Running sudo chmod +rx brainfuck does not solve the issue? Did you run make as normal user by the way?

[smlavine]

No, sudo chmod +rx brainfuck didn't do anything, and make was ran as a normal user.

[fabianishere]

What filesystem are you using? It could be related to your filesystem not supporting permissions or it being mounted as non-executable.

[smlavine]

It works now! The problem was that the interpreter was on a flash drive, I think. +++++++++++++++++++++[>++++[>+<-]<-]>>.++++++++++++++++++++.-------.+++++++++++++.---.<<++++++++[>++++[>>+<<-]<-]>>>.<++++++++++++++.----------.++++++.>.<+.-----------------.+++++++++++++.+++++++.>.<------------.++++++++.------------------.+++++.>+.
