Errors while trying to build the kernel.

[mattgk1996]

I was trying to install akaros to try to implement another scheduling algorithm. But i cant seem install it. One error after the other. I built the cross compiler. x86_64 But i am not able to build the kernel.

This is what i did. opened gedit .bashrc added this to the end of it-->export PATH="<pathofbin:$PATH" saved it. opened a new terminal. went to the akaros-master directory. then-->sudo make but the following error was reported " Could not find a x86_64-ucb-akaros- version of GCC/binutils. Be sure to build the cross-compiler and update your PATH make: *\ [cc-exists] Error 1 "

then tried--> $sudo -s $PATH="/home/matthew/install/x86_64-ucb-akaros-gcc/bin:$PATH" $make

then i got this error. " CC kern/src/error.o kern/src/error.c:3:1: error: expected expression at end of input const char _errnostrings[] = { ^ make[1]: ** [kern/src/error.o] Error 1 make: *\ [kern/src] Error 2 "

Can someone please help me??

I don't build it with sudo. Maybe that is causing some issues?

then i got this error " CC kern/src/erroro kern/src/errorc:3:1: error: expected expression at end of input const char _errnostrings[] = { ^ make[1]: ** [kern/src/erroro] Error 1 make: *\ [kern/src] Error 2 "

That looks a little weird. For some debugging output, try this:

$ make V=1

That will give the commands make (via Kbuild) is using. Then we can try the command that is failing directly and try to debug that.

Also, the formatting of the error looks like it's losing characters. For instance, the file is "kern/src/error.c", not "kern/src/errorc".

Keep in mind that kern/src/error.c is generated at compile time. Take a look at the top of kern/src/Kbuild. If the cross compiler isn't working properly it wont be able to generate this file.

Or rather, if it can't read the .h file (possibly because permissions are wrong because of the sudo) then the script wont generate this file properly.

Hey, I didnt initialise the PATH before i built the compiler. I think that was why I was getting all these errors. Thanks a ton though!
