Hi everyone,

im trying to compile a kernel for my phone, but i get an error from make :

Code:

make: /home/r1d3r/code/arm-2010q1/bin/arm-none-eabi-gcc: Command not found

but the file already exists:

Code:

r1d3r@r1d3r-0:~/code/arm-2010q1/bin$ ls
arm-none-eabi-addr2line  arm-none-eabi-gcc-4.4.1  arm-none-eabi-objdump
arm-none-eabi-ar	 arm-none-eabi-gcov	  arm-none-eabi-ranlib
arm-none-eabi-as	 arm-none-eabi-gdb	  arm-none-eabi-readelf
arm-none-eabi-c++	 arm-none-eabi-gdbtui	  arm-none-eabi-run

r1d3r@r1d3r-0:~/code/arm-2010q1/bin$ ./arm-none-eabi-gcc
bash: ./arm-none-eabi-gcc: No such file or directory

do u guys have an idea what might be the problem?

PS: im running ubuntu 12.04

Thanks in advance.

in such cases usually the first line of that file contains an interpreter, like here:
#!/path/to/interpreter
it is used to be /bin/bash, but in your case that file does not exists.

"arm-none-eabi-gcc" is a binary and the makefile doesnt need the #! but i even tried adding it to the beginning of the makefile, and the problem persists.

is it possible that the config of bash got corrupted somehow?

thanks for your help.

You are right, for makefiles the #! is not used although it would be possible.
You can check how the SHELL variable set. Which make have you tried? Also you can try if that file (/home/r1d3r/code/arm-2010q1/bin/arm-none-eabi-gcc) can be executed from the command line without make. Have you checked the permissions?

Is it executable? Is it the right binary format for the system you are trying to run it on? file arm-none-eabi-gcc would show what sort of binary it is. Is it named as it appears to be named? How does its full path look when listed with the --escape option of ls?

ok i found the problem, its a 32bit binary, and im running a 64bit OS.

Code:

arm-none-eabi-gcc: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.2.5, stripped

after a quick search in the ubunru wiki, i found out that i need to install "ia32-libs" to run 32bit executables, and voila! its working now :-)

thank you guys for your help, i was about to start pulling my hair from desperation.

best regards.
