gdal-grass build fails to find libraries when grass is Grass 6.4

[macports-trac@…]

The code in the Portfile to detect the macports installation of Grass 6.4 as /Applications/GRASS-6.4.app fails, and the flag sent to the configure command is actually --with-grass=/opt/local:

In order to get around the bug where gdal-grass has a false dependence on the nonexistent port grass64, I modified the following lines in the Portfile

# Select Grass version

variant grass64 description "Builds against grass64" {
	depends_lib-delete		port:grass
	depends_lib-append		port:grass64
	
	configure.args-delete	--with-grass=${prefix}/lib
	
	if {[file exists ${applications_dir}/GRASS-6.4.app]} {
		configure.args-append	\
			--with-grass=${applications_dir}/GRASS-6.4.app/Contents/MacOS/
	} else {
		configure.args-append --with-grass=${prefix}
	}
}

to read

# Select Grass version

variant grass64 description "Builds against grass64" {
	
    configure.args-delete	--with-grass=${prefix}
	
		configure.args-append	\
			--with-grass=${applications_dir}/GRASS-6.4.app/Contents/MacOS/lib
}

Even with this modification, configure fails to find Grass to its satisfaction.

Should be fixed by r76526. Please update, try again and tell me.

Log of destroot failure after change r76526.

[macports-trac@…]

Installation now fails in a different way (see attached log file, which was produced after a port clean --all gdal-grass).

Looking at /opt/local/lib after the failed install, there's a gdalplugins directory with the built binaries in it; the failed build doesn't leave a work/destroot directory behind.

It seems that the make install during staging into destroot is targeting the ultimate location for the binaries rather than the staging hierarchy under work/destroot. The modifications to the Makefile seem to leave it in a state with no reference to the DESTROOT flag, whose value needs to be prefixed to the directories given in the install: goal (if I understand things correctly).

Thanks for looking into this! We're almost there.

I can't reproduce this. On my side, it works perfectly well

(I use /usr/pkg rather than /opt/local because of a NetBSD package legacy) Maybe clean and try again?

The state of the Makefile at the point of failure

[macports-trac@…]

I have reproduced this on a freshly erased Macports tree on a machine on which I don't do development. I reinstalled Macports 1.9.2 and issued the command "sudo port install gdal-grass". I had to do "port install db46 +no_java" beforehand owing to an obviously unrelated bug in the Java dependency in that port.

I have attached the Makefile that is created for gdal-grass.

Build environment: Mac Mini 1.66 GHz Intel Core Duo running Mac OS X 10.6.6.

Ah, there was a fix for that, but only for universal builds! :| Try with r76566.

[macports-trac@…]

Confirmed: r76566 fixes the issue.

Thanks!
