grass: projects.h not found

I get the following error when trying to install grass:

Some googling suggests that projects.h is a member of libproj4, but the error persists if I install the libproj4 package. So it's not a simple missing dependency, but a deeper build error.

I am running MacPorts base version 2.1.1 on OS 10.6.8.

i get the same error when building CDO with

sudo port clean cdo
sudo port install cdo
--->  Building cdo
Error: org.macports.build for port cdo returned: command execution failed

then the main.log has the following

:info:build grid.c:25:24: error: projects.h: No such file or directory

Same system as the OP: Macports 2.1.1, OS 10.6.8, Xcode 3.2.6, gcc 4.2.1

So before issuing a new ticket, i thick could be related.

I have the same error for CDO. Similar to GRASS, CDO relies on chartographic projections and the library libproj4. If i issue the command

port contents libproj4
Port libproj4 contains:
  /opt/local/bin/lproj4
  /opt/local/include/lib_proj.h
  /opt/local/lib/libproj4.a

there's no file 'projects.h', 'lib_proj.h' instead. AFAIK, Macports doesn't support manual dependencies, but i can surely be wrong.

Looks like ​"projects.h" was intentionally removed from proj in version 4.8.0, to which the proj port was recently updated. "projects.h" is a private proj header that other software should never have been using; now proj is enforcing this.

This ticket is about grass. File additional tickets for cdo and any other port that needs to be fixed. Each port needs to be fixed individually.

As a workaround for now, you could downgrade to proj 4.7.0. This might have other consequences though.

Replying to ryandesign@…:

Indeed, thanks for pointing this out.

Ok, i will.

It worked. Istalled proj revision 58983, activated it and reinstalled cdo.

So far no apparent consequences on other gis ports though (gmt, for instance).

Thanks a lot.

Thanks for the workaround, Ryan. So is this a bug that should be filed with the GRASS developers?

I created a patch of proj (#35009). This is an adhoc fix. The developers of grass and cdo (#34991) should use the public header proj_api.h rather than the private header projects.h. I will ask the developers of cdo to see if they can address the problem.

[tenomoto (Takeshi Enomoto)]

Upon Ryan's comment, I abandoned the patch and created proj47 port. I also found that it does not work with clang. I allowed both openmotif and lesstif (#24960). Committed in r94769.
