circular dependency apple-gcc42/xpm, and many others

[herzog-bernd]

Machine: PowerBook G4, 15"

PowerBook5,4

CPU-Type: PowerPC G4 (1.1)

OS Version: 10.4.11

Xcode verson: 2.4.1

Problem:

========

The attempt to install xemacs,

sudo port install xemacs

failes since the port 'apple-gcc42' is required, which in turn requires 'xpm' The install procedure stops with the message

:error:build failed to install apple-gcc42
:debug:build Registry error: xpm not registerd as installed & active

in the logfile /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_apple-gcc42/apple-gcc42/main.log

The attempt to install xpm,

sudo port install xpm

failes since the port 'apple-gcc42' is required

The xpm is by far not the only port which is in such a circular relation to apple-gcc42. Part of the error message was a list (see below). I just tried several ports at the beginning and at the end of the list. It turned out that all these are in the same circular dependency to 'apple-gcc42' like 'xpm'.

It is true that most ports on Tiger will require apple-gcc42 because that is the default compiler on Tiger.

However, I don't know why building apple-gcc42 would require xpm. Could you please attach the main.log file from your failed apple-gcc42 build?

[herzog-bernd]

The content of the main log file /opt/local/var/macports/logs/_opt_local_var_macports_sources_rsync.macports.org_release_tarballs_ports_lang_apple-gcc42/apple-gcc42/main.log is as follows. Maybe it has change, since I tried, aftert the install attempt of xemacs, to install xpm, xorg-libice, xorg-xtrans.Should I redo 'sudo port install xemacs'?

Don't forget to use WikiFormatting where needed, such as when showing lines of terminal output.

It's better to attach large output than to paste it. I've converted your log into an attachment​.

It says:

:debug:main Skipping completed org.macports.configure (apple-gcc42)

This indicates it was not a ​clean build attempt. Please "sudo port clean apple-gcc42", then try again. If it fails again, attach the new main.log.

It also says:

:info:build checking for C compiler default output file name... configure: error: C compiler cannot create executables
:info:build See `config.log' for more details.

If this error happens again after you clean and try again, please attach the config.log as well.

[herzog-bernd]

I did as you told me:

cd ~/MacPorts/
sudo port clean apple-gcc42 2>&1 | tee ./cleanGcc42Log.txt
port install apple-gcc42 2>&1 | tee ./installGcc42Log.txt

Again there is the message 'C compiler cannot create executables' I am attaching the above *Log.txt files and the main.log. I am not sure which config.log You have in mind, so I am attaching the one inside the MacPorts-2.3.3 folder.

P.S.: Unfortunately I do not know anything about WikiFormatting. I will try to learn it as soon as I have the time for. At the moment can spend only few minutes for communication, and I think, to be fast is more important than to be correct. Please excuse me.

Replying to herzog@…:

It’s not entirely clear which configure run is failing, but I think the relevant config.log is one of these:

• $(port work apple-gcc42)/objroot/obj-x86_64-i686/intl/config.log
• $(port work apple-gcc42)/objroot/obj-x86_64-x86_64/intl/config.log

Please attach both.

The most important bit for our purposes is the use of triple braces for creating preformatted text. Such text is rendered inside an HTML pre tag, so newlines and whitespace are respected.

The path names seem to point to Intel directories. The machine in question is a Power PC Macintosh.

The config.log says the reason for the problem is:

ERROR: No debug map or DWARF data was found to link.

Googling that error, I found ​another project explaining that this error can be resolved by upgrading to Xcode 2.5. Can you try that?

[herzog-bernd]

A change to Xcode 2.5 would be a problem for me, since several of my projects building very well with Xcode 2.4.1 don't with Xcode 2.5. Mainly because of a change in Interface Builder. Moreover, according to Apple's release notes, Xcode 2.5 cannot be used to develop for Mac OS 10.5. A change to Xcode 3 seems to be impossible, too, since it doesn't run with Mac OS 10.4.

Nevertheless, I have tried to use Xcode 2.5 running the system from an external drive, and the problem remains.

So I returned to Xcode 2.4.1 and tried to build apple-gcc42 manually following the hints in the file

	$(port work apple-gcc42)/gcc-5666.3/README.Apple

I created a folder

	testplace,

copied the archive 'gcc-5666.3.tar.gz' into a subdirectory of my home directory, expanded it into a folder named

	gcc-5666.3,

changed into this folder and called

	mkdir darwin
	cd darwin
	../configure --prefix=/testplace
	make bootstrap
	make install

Already the configure script is a problem. It assumes that the minimum Mac OX is system 10.5 and that the source root is

	/Developer/SDKs/MacOSX10.5.sdk

Such a source root directory doesn't exist, neither with Xcode 2.4.1 nor with Xcode 2.5. So one shouldn't be worried that compilation fails. I tried to call configure with the option

	--with-build-sysroot=/Developer/SDKs/MacOSX10.4u.sdk

Actually, I added further options to be as close as possible to the call done by the apple-gcc42 port:

	--prefix=/testplace
	--enable-languages=c,c++,objc,obj-c++
	--with-system-zlib
	--disable-nls
	--with-slibdir=/usr/lib
	--with-gxx-include-dir=/usr/include/c++/4.0.0
	--host=powerpc-apple-darwin8
	--target=powerpc-apple-darwin8

In addition, I had to create a directory

	testplace/powerpc-apple-darwin8/lib

to avoid 'no such directory' errors from the bootstrap script and a hard link

	testplace/powerpc-apple-darwin8/include

pointing to /usr/include, for otherwise, after a time of compilation, I got complains that c standard headers like 'errno.h' and 'time.h' were missing. I am not sure whether the link points to the correct location. Maybe it should point to a location inside the '/opt' directory containing these headers?

Finally, at the end of the build process for 'libgcc_s.1.dylib.tmp', the linker reports

	/usr/bin/ld: -syslibroot: multiply specified

and stops execution of the bootstrap script. Indeed one finds as arguments to the linker both

	-isysroot /Developer/SDKs/MacOSX10.4u.sdk (specified twice)
	and
	-isysroot/Developer/SDKs/MacOSX10.5.sdk

This seems to be a build or configure script or Makefile bug. Since I have no idea about the gcc build mechanism I even don't know where to look for it.

All the actions above are assembled in the script

	build_gcc1.xc

and its output in the text files

	configure1Log.txt
	bootstrap1Log.txt

(attached to this report).

My claim that the build of 'apple-gcc42' fails with Xcode 2.5 is wrong. The second attempt to upgrade from Xcode 2.4.1 to version 2.5 and then to install 'apple-gcc42' was successful. Actually I can't tell what went wrong in the first attempt. Maybe the deinstallation of the old Xcode version was incorrect.

Questions:

	1)	Is it possible to return to the old Xcode version now?
	2)	Is it possible to use MacPorts applications from a different
		startup disc, where Xcode 2.4.1 and no MacPorts data are
                installed ?

Best, Bernd Herzog

[ryandesign (Ryan Carsten Schmidt)]

Thanks for confirming. I've updated the apple-gcc42 port to require Xcode 2.5 in r151945.

Presumably it would be no problem to go back to an older Xcode now if you wanted to. Of course, if MacPorts publishes an update for apple-gcc42, you'll need Xcode 2.5 again to build it.

Software installed with MacPorts is designed to be used on the computer and OS on which it was installed. You should not, for example, use MacPorts installed on an external drive attached to a PowerBook G4 running Tiger to install some ports, then move that external drive to a MacBook Pro running El Capitan and expect the software you installed with MacPorts on Tiger to be usable there.

But if you mean just running MacPorts-installed software from another disk, on the same computer and same OS version, then that's more likely to work. MacPorts and Xcode are not needed to run the software that was installed, only to install it in the first place. You may need to account for different paths, however. If you installed software on your startup disk using MacPorts in /opt/local, and then later boot up from a different disk, now MacPorts is no longer at /opt/local but is instead at /Volumes/YourDiskName/opt/local. Most software installed with MacPorts can't be run from another path; you'll get an error that libraries can't be found at the original /opt/local/... path. The simple workaround for this problem is to create an appropriate /opt/local symlink on your new boot disk. For example:

sudo mkdir -p /opt
cd /opt
sudo ln -s /Volumes/YourDiskName/opt/local local

Before you do this, if YourDiskName contains spaces or other special characters, use the Finder to rename it so that it doesn't. For example, if the disk you have MacPorts on is named "Macintosh HD", rename it to e.g. "MacintoshHD".
