Building for an Intel Mac

[russurquhart1]

Hi, As i said in the mailing list. The version of Clang (11.0 i think), installed by default, does not recognize '-mlong-double-64' option. (I checked my default gcc compiler and that also did not support this option.) I'm not running the latest version of MAC OS, I'm still running version 10.15.7 because I have an application that discontinued support for, after this OS version. I think I'll try first removing the option from the Make file, and see if that works and goes further. If there are still issues, I thought I'd install the latest gcc from brew, point CC to the gcc location, and try again. Thoughts?

Thanks again,

Russ

I removed the '-mlong-double-64' option, and it seemed to progress further, but I think the issues being found relate to the old Clang being used. Here are the errors:

Do you think I should try installing gcc from brew and pointing CC to it, and then try building that way?

Thanks,

Russ

I would try using gcc. If you already have a version of gcc installed, all you should need to do is make sure it's in your path and do a CC=gcc make ...

The error on the missing malloc.h header.. it looks like you can just remove that include (it should be picked up in stdlib.h)

[CheyenneWills]

The other error (about conflicting types), might be due to a header file getting pulled in twice.

[russurquhart1]

I set CC to point to /usr/bin/gcc

And I commented out the include for malloc.h in osint/syslinux.c

Still got the type errors:

Any ideas for this? Thanks for all your help.

[CheyenneWills]

I'll go through the code to see what includes are being used vs what is actually needed.

[CheyenneWills]

I pushed a branch mac-WIP that can be used to while working on the Intel Mac port.

Try building against this branch. For the Mac build, there may be more include problems and you might need to play around with changing some of the includes. . It could very well be that the Mac development environment has moved some of the stuff into different header files. You can try commenting out some of the system includes in osint/port.h, do a build, then see which Mac specific include contains the definitions that are missing.

[russurquhart1]

The changes I made in the things that I showed you were on my local branch. Should I push those to this new branch? Or just pull down the new branch and make sure that it has those changes in them?

You can commit your changes to a local branch on your system, then rebase that branch on top of the one I created -- depends on how comfortable you are with git.

Otherwise, use the branch I created, and make the same set of changes (if needed).

I commented out the unistd.h include file in port.h and got much further. it eventually failed with a linker error:

[CheyenneWills]

There are 2 issues you are now running into.

1st, while you removing the unistd.h include "fixed" the error, you have missing macros and other declarations. To fix, you will need to determine what includes from the Mac SDK are needed to resolve those.

The 2nd problem is that you are missing one or more libraries needed from the Mac SDK (these would be adding new -l{something} to the "cc" command were all the .o files are linked (e.g. $(CC) $(CFLAGS) *.o -o sbl -lm -l{something for Mac}

[russurquhart1]

Ok, thanks, I'll look into that!

[russurquhart1]

BTW, do you happen to know the file where those macros would be, in a normal Linux system?

[CheyenneWills]

BTW, do you happen to know the file where those macros would be, in a normal Linux system?

They are in the unistd.h

So you will need to investigate where the Mac SDK has those macros, or figure out what is causing the error when using the Mac SDK unistd.h file.
