How to build on OSX (possibly)

[futurepr0n]

Working through getting the build on OSX, here is what I have done along the way with issues I have encountered and how I managed to get passed some of them.

First problem I had was when building it could not find objcopy or gobjcopy

So first I made sure I had brew install binutils installed and then I was required to also run the following:

export PATH=/usr/local/opt/binutils/bin:$PATH 
export LDFLAGS="-L/usr/local/opt/binutils/lib"
export CPPFLAGS="-I/usr/local/opt/binutils/include"

Next I re-ran ./configure --enable-local, things looked good until I encountered

checking for help2man... no
configure: error: missing required tool: help2man

Once again I ran brew install help2man and you may not run into this issue but I could not link it

To get around this brew link would not work either, so I found an article where fixing that issue was to run sudo chown -R $(whoami) $(brew --prefix)/* after that I executed the brew link help2man successfully and ran ./configure --enable-local . Successfully.

Next, steps:

 cd ..
 cp configs/sh2eb-elf/native-linux.config .config

Still at the moment trying to get passed the next part, as build sh2 part fails

Thanks for looking into this. Unfortunately I don't have immediate access to a MacOS machine at the moment. Could you try looking at this reply from another repository issue?

The idea is the same as to how I build the Windows tool-chain. It's a Canadian Cross build. That is, first you build a compiler that runs on Linux, that generates MacOS executables. Then the second step is you use the compiler from the first step to target SH-2. At the end you'll end up with a compiler that runs on MacOS and targets SH-2.

Thanks I will check out in detail, but at immediate glance I don't know if this was same thing I ran into. I was able to build cross tool successfully, but not able to build using cross tool due to the local disk being non case sensitive.

Please fix it up and finish by exiting the shell with one of these values:

    3  abort build

I have been able to use the docker build now and I might admit defeat in this regard unless there is some way to change that out of the crosstool build portion? Could I comment parts out that are strictly checking it? Or can I change the paths where this happens and make the path same as where I am running the build? Or will there be dependencies that are going to need the strict case sensitivity after this part too?

If I can change this path and if nothing matters after that I may be successful native.

[ijacquez]

crosstool-ng looks at .config. You can change the path by modifying this variable:

CT_PREFIX_DIR="${CT_PREFIX:-${HOME}/.local/x-tools}/${CT_HOST:+HOST-${CT_HOST}/}${CT_TARGET}"

You can change it to:

CT_PREFIX_DIR="${CT_PREFIX:-/path/to/your/case-sensitive-volume/x-tools}/${CT_HOST:+HOST-${CT_HOST}/}${CT_TARGET}"

[futurepr0n]

tried changing the path and hardcoding it to where would be case sensitive and valid, but new errors during the process came up - it was unable to run with failed current command "mkdir" "-p" - something about this just does not want to work smoothly with mac and thats ok - the docker build seems to be a great alternative. Thank you for the help and trying

[ijacquez]

Thanks @futurepr0n.

I'll keep this open.
