[GitHub] [incubator-nuttx] GUIDINGLI opened a new pull request #1817: SIM in MacOS: make MacOS link process same with Linux

GUIDINGLI opened a new pull request #1817:
URL: https://github.com/apache/incubator-nuttx/pull/1817


   
   
   ## Summary
   
   SIM in MacOS: make MacOS link process same with Linux
   
   ## Impact
   
   1. There is difference about symbol replace on nuttx-names.in
      between MacOS & Linux
   2. For MacOS, if open '-fvisibility=hidden' and adjust nuttx-names.in,
      it will meet symbol link-back-to-nuttx error.
   3. Make the MacOS replace behaviour, same with Linux
   
   Note:
   MacOS should install objcopy with command:
   $ brew install binutils
   $ export PATH=$PATH:/usr/local/opt/binutils/bin
   
   already check in to cibuild.sh
   
   ## Testing

   @yamt thanks for your help.
   My binutils info is similar to your's except that my info has some explanations about the path. (I did these recommendations previously).
   
   There may be a corruption in developer tools because I did many trials to resolve this issue for instance I installed crosstools-ng acoording to [this paper](https://pigiuz.wordpress.com/2013/09/12/resolving-symbols-conflict-between-libraries-on-osx-with-objcopy/) and installed (removed afterwards) the prerequisites - recommended tools [here](https://nuttx-companion.readthedocs.io/en/latest/user/install.html)  
   
   For instance my system has gobjcopy as well and it has exact same version with the objcopy ?
   `apple-mbp:~ murat$ gobjcopy --version

   Binutils info:

   ==> Caveats
   binutils is keg-only, which means it was not symlinked into /usr/local,
   because Apple's CLT provides the same tools.
   
   If you need to have binutils first in your PATH run:
     echo 'export PATH="/usr/local/opt/binutils/bin:$PATH"' >> /Users/murat/.bash_profile
   
   For compilers to find binutils you may need to set:
     export LDFLAGS="-L/usr/local/opt/binutils/lib"
     export CPPFLAGS="-I/usr/local/opt/binutils/include"

   @xiaoxiang781216 thanks for your kind answer. I did, but I understand that my path was wrong, with the exact path you've given my build pass the objcopy but now I get undefined symbol error like this:

   @TA1DB which version of objcopy are you using?
   
   i'm using:
   ```
   spacetanuki% brew info binutils

   ```
   
   it might be version-sensitive because this is the first version i've seen working ok.
   when i tried an earlier verion before, it produced a broken binary.
   (that was why macOS port has been done differently)

   @yamt 
   I have add the objcopy PATH to env.sh at:
   https://github.com/apache/incubator-nuttx-testing/pull/64
   
   ln -s /usr/local/opt/binutils/bin/objcopy /Users/runner/work/incubator-nuttx-testing/incubator-nuttx-testing/prebuilt/bintools/bin/objcopy
   add_path /Users/runner/work/incubator-nuttx-testing/incubator-nuttx-testing/prebuilt/bintools/bin
   
   then I have seen PATH will be write to env.sh
   
   But how to use env.sh ?
   
   This I have seen your history commit on generated env.sh, but can't see where to use it.
   This will caused https://github.com/apache/incubator-nuttx/pull/1817 compile failed.

   @GUIDINGLI 
   env.sh is to be sourced to set up PATH to prebuilt binaries.
   like:
   
       . $prebuilt/env.sh
   
   as far as i know, it isn't used for the ci.

   @yamt 
   
   this patch will take place of :
   https://github.com/apache/incubator-nuttx/pull/1813
   
   If you test pass, 
   then first check in https://github.com/apache/incubator-nuttx-testing/pull/63
   thus, this will compile pass on MacOS

   @TA1DB 
   one thing you can try is to copy the objcopy binary into a dedicated directory (eg. ~/bin) and tweak your PATH to look at there, instead of /usr/local/opt/binutils/bin.
   brew binutils package has too many things which might conflict with the host toolchain. it's better to ensure that only objcopy is used from binutils.
