Compiling rockbox using a mac?

[brogan]

I was wondering if someone can explain in detail how i could compile rockbox onto my nano using a macintosh(10.39)... I already have rockbox on my ipod, and i just figured out how to apply a patch to the source, but now im stuck on compiling, please help.. thanks

um... im still confused, it seems like everything is focused on compiling for windows or linux, and the linux part says.. "(or any unix based os)" .. or something like that so does that mean macs also.. or what.
and what exactly is a crosscompiler, what does that mean...
i tried following a simpleguidetocompiling, but i got stuck when it said to type make into terminal it. terminal said it wasn't a command, and apparrantly it's a linux command, and so how am i supposed to compile, if i don't know a compile command.... sorry if this didn't make sense, and i know i probably mixed things up, but thanks for your help

A compiler is a program that takes source code and compiles it into executable code for a specific processor/architecture.

A cross-compiler is simply a compiler that you run on one architecture (the "host" - e.g. your Mac) and compiles source code to run on another architecture (the "target" e.g. your Nano).  A normal compiler is one where host and target are the same.

Firstly, you'll need to make sure you have all the standard OS X development tools installed (this includes programs such as "make" - a standard Unix command, NOT specific to Linux).  To do this, install "xcode" from Apple - if a copy didn't come on the CD/DVDs with your Mac, you can download it from Apple.

After that, the Linux/Unix instructions should work.

thanks, that explained alot ...
alright, but i still want to make sure im doing this right...
so i followed the instructions here: http://www.rockbox.org/twiki/bin/view/Main/LinuxSimpleGuideToCompiling
after i dowloaded xcode legacy version(i have mac 10.39) from here: https://connect.apple.com/cgi-bin/WebObjects/MemberSite.woa/304/wo/4l5Kl1PHgSVh2z60PUDKtFZmiGy/3.1.17.2.1.3.3.1.1.1.1.0.3.3.3.3.1

the problem was when the instructions said to type "make".. as before it said it wasn't a command
maybe i didn't download xcode right, but im pretty sure atleast i installed it right, jus maybe not the right version, please help
thanx

Alright... i figured out all those things from before with xcode etc..., but i now i have had a couple of more problems.. first i will show u what i did(ill skip the first couple steps....) i was following the instructions from here: http://www.rockbox.org/twiki/bin/view/Main/CrossCompiler, and here: http://www.rockbox.org/twiki/bin/view/Main/SimpleGuideToCompiling .. and the linux section as well...

ok so i ran the rockboxdev.sh file in the tools/ directory.. it ran for a while, and it seemed to have worked.
then i typed,     export PATH=$PATH:/usr/local/arm-elf/bin:/usr/local/m68k-elf/bin:/usr/local/sh-elf/bin        in terminal to set the path.... after that i  created a build directory (build) in the rockbox source directory and then i typed,    ../tools/configure    to run configure, i set it up for an ipod nano (21)with a normal build(N)....
then the problem came when it said:

../tools/configure: line 1: arm-elf-gcc: command not found
../tools/configure: line 1: arm-elf-ld: command not found
WARNING: The compiler you must use (arm-elf-gcc) is not in your path!
WARNING: this may cause your build to fail since we cannot do the
WARNING: checks we want now.
Using arm-elf-ld

......
and so i tried to just ignore it and i typed,    make    .. and it said( i used ___ for my username, in case u r wondering what ___ means..):

/Users/____/desktop/rockbox-18826/tools/svnversion.sh: line 1: svnversion: command not found
/Users/_____/desktop/rockbox-18826/tools/svnversion.sh: line 1: svnversion: command not found

after that i typed make zip just to see if anything would happen and a .rockbox directory was created, but lots of the files, esp. plugins were missing.... so
please help... and thanks to those who've helped me so far...

[saratoga]

then i typed,     export PATH=$PATH:/usr/local/arm-elf/bin:/usr/local/m68k-elf/bin:/usr/local/sh-elf/bin        in terminal to set the path....

../tools/configure: line 1: arm-elf-gcc: command not found

According to that error,  you did not successfully add the compiler to your PATH.  You can check your PATH by typing "echo PATH".  Confirm that the directory where your arm-elf-gcc was installed to is listed there.

"echo PATH"

That's "echo $PATH".

alright... so how do i change the path so it works.. and how do i find the directory that has arm-elf-gcc in it... i can't find it.. thanx

Did you not install it to /usr/local/arm-elf/ as you suggested above?

[brogan]

First of all, i just want to say that i really appreciate the help...... but I'm still confused on how to change the path...... and where to find /usr/local/arm-elf/  i tried to find a usr directory and couldn't find one.. i even searched.. and had no success.... so how exactly do i find arm-elf-gcc , and how do put it into the path.. thanks.

The command you used above should do it.  Since it did not, either you've put the compiler somewhere else, rockboxdev did not run, or you did not type the command correctly.  Since you can't find where it installed to, you could run it again, paying attention to the install directory and making sure the tool completes. 

[brogan]

I found a folder called usr/ and then i clicked on local/ but all the folders and next couple files and folders were font forge related ... then back in macintosh hd/ i saw a folder called tmp/ inside was rbdev-build/summary-a/ and rbdev-dl/binutils......bz2, gcc-core.... bz2, and rockbox-... arm-elf-gcc...dff/
what do u recomend that I do from here?

[GodEater]

Try opening a terminal window, and doing the following :

Code: [Select]

find / -name "arm-elf-gcc" -print

The  change to a later gcc means the linux instructions are now broken.

A work around is to use

sudo CPPFLAGS=-U_FORTIFY_SOURCE ./rockboxdev.sh
