You're running into a known cctoools bug. Please try the following:

sudo port install cctools +xcode
sudo port clean poppler
sudo port install poppler

Duplicate of #61967

If the above fails, please reopen this ticket and note the new build log based off of cctools +xcode.

comment:3 Changed 4 years ago by szhorvat (Szabolcs Horvát)

This did indeed work, but I'm confused: I already had the +xcode variant installed. So what did sudo port install cctools +xcode accomplish them?

comment:4 Changed 4 years ago by kencu (Ken)

actually, it's officially a poppler bug now, because -macho is no longer a valid flag to use (but older llvm's still accept it).

Replying to szhorvat:

now that is a puzzle....if you can reproduce it, perhaps we can sort out that voodoo.

comment:7 Changed 4 years ago by kencu (Ken)

but --which software exactly is adding the flag? poppler, or go-i?

comment:8 Changed 4 years ago by michaelld (Michael Dickens)

... or neither? doing a quick "grep" on the source for "macho" shows nothing. I'm guessing this is in the scanner & it's coming from some Python import. Let me do some sleuthing ...

comment:9 Changed 4 years ago by michaelld (Michael Dickens)

"source" here being both GO-I and Poppler ... which is why I think flag is being added in elsewhere ...

Adding -v to the system call to clang, I see this:

There is no -macho in the command call. Might be in the call environment ... looking into that.

OK some progress!

(0) make sure you have cctools +llvm11 installed.

(1) Add this to the Portfile for GO-I or poppler: build.env-append "GI_SCANNER_DEBUG=save-temps"

(2) issue sudo port build poppler or GO-I etc... it should fail during a GO-I scan

(3) review the log for the otool -L command being issued; for example here's the one from 'poppler' that I see

:info:build Caught exception: <class 'subprocess.CalledProcessError'> CalledProcessError(1, ['otool', '-L', '/opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_graphics_poppler/poppler/work/build/glib/tmp-introspectdnhi97mq/Poppler-0.18'])

(4) reform and issue this command directly; from my (3) I'd do:

otool -L /opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_graphics_poppler/poppler/work/build/glib/tmp-introspectdnhi97mq/Poppler-0.18

which for me results in the following:

llvm-objdump: Unknown command line argument '-macho'.  Try: '/opt/local/libexec/llvm-11/bin/llvm-objdump --help'
llvm-objdump: Did you mean '-h'?
llvm-objdump: Unknown command line argument '-dylibs-used'.  Try: '/opt/local/libexec/llvm-11/bin/llvm-objdump --help'
llvm-objdump: Did you mean '--dylibs-used'?
llvm-objdump: Unknown command line argument '-non-verbose'.  Try: '/opt/local/libexec/llvm-11/bin/llvm-objdump --help'
llvm-objdump: Did you mean '--non-verbose'?

(5) now do sudo port install cctools +xcode to load up a different otool

(6) reissue the command from (4), which now for me does:

otool -L /opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_graphics_poppler/poppler/work/build/glib/tmp-introspectdnhi97mq/Poppler-0.18
/opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_graphics_poppler/poppler/work/build/glib/tmp-introspectdnhi97mq/Poppler-0.18:

	/System/Library/Frameworks/CoreFoundation.framework/Versions/A/CoreFoundation (compatibility version 150.0.0, current version 1770.255.0)
	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1292.60.1)

This implies to me that the issue is actually with cctools and/or llvm here, since the exact same command using different variants of cctools results in success or failure.

comment:12 Changed 4 years ago by michaelld (Michael Dickens)

Quick note that otool for variant +xcode is provided by Xcode while that for +llvm11 is provided directly by cctools ... so guessing that there's some change in how otool calls objdump between llvm10 and llvm11, since the former works but the latter doesn't, at least in this regard.

comment:13 Changed 4 years ago by kencu (Ken)

yes, they changed the accepted flag between those two.

The exact commit is referenced in one of these tickets, if that is of any interest, but there's nothing fancy in the commit: just "we don't accept -macho anymore".

comment:14 Changed 4 years ago by kencu (Ken)

Soon, that will flow into xcode, and xcode's llvm-objdump won't accept it either, unless Apple's fork keeps it patch to accept the flag for a few years (which is what I would do -- I"m not sure what amount of OCD behaviour led them to decide to start rejecting the flag anyway, and cause all this heartache for no visible benefit -- but I digress).

looking at the cctools code in cctools-927.0.2/otool/main.c, line 80 reads:

enum bool show_objdump_command = FALSE; /* print the objdump command */

change this to TRUE; build and install. then run the otool command again:

+ /opt/local/bin/llvm-objdump-mp-11 -macho -dylibs-used -non-verbose /opt/local/var/macports/build/_opt_sources_MacPorts_ports_github_macports_graphics_poppler/poppler/work/build/glib/tmp-introspectdnhi97mq/Poppler-0.18
llvm-objdump: Unknown command line argument '-macho'.  Try: '/opt/local/libexec/llvm-11/bin/llvm-objdump --help'
llvm-objdump: Did you mean '-h'?
llvm-objdump: Unknown command line argument '-dylibs-used'.  Try: '/opt/local/libexec/llvm-11/bin/llvm-objdump --help'
llvm-objdump: Did you mean '--dylibs-used'?
llvm-objdump: Unknown command line argument '-non-verbose'.  Try: '/opt/local/libexec/llvm-11/bin/llvm-objdump --help'
llvm-objdump: Did you mean '--non-verbose'?

... so ... this is a cctools issue, not GO-I or poppler.

So this is a duplicate of #61967 ... and that ticket's topic is correct / relevant. How about let's close this in favor of just that other ticket?
