Is PROJ v6 supported?
Added by Thiago dos Santos over 5 years ago
Dear all,
I have replaced PROJ 4 with the newer PROJ 6 (https://proj.org/news.html#id28) on my Ubuntu system.
Now I am trying to recompile CDO to benefit from the newer PROJ. I am using the "--with-proj=" configure argument, but CDO doesn't seem to find proj's header file:
checking proj_api.h usability... no
checking proj_api.h presence... no
checking for proj_api.h... no
checking for library containing pj_init... -lproj
However, the files are there:
ls /opt/software/lib/libproj.*

I am also receiving some errors during the compilation (which halts at some point):

Am I missing something? Or is PROJ 6 not yet supported by CDO?
Cheers,
Thiago.

Hello Thiago,
we currently do not support v6. We only support the usage of v6 with the use of ACCEPT_USE_OF_DEPRECATED_PROJ_API_H which uses the old api.
We will have to adapt cdo to the interface changes in v6/v7. We are planning to do this a few months before v7 releases.
For now you can configure cdo with CFLAGS="-DACCEPT_USE_OF_DEPRECATED_PROJ_API_H" is available in v6 and will be removed in v7 together with the old api.
Cheers,
Oliver.

Hi Oliver,
Thanks for the hint. CDO now builds fine with PROJ 6.0.0 - all I had to do was to add the "-DACCEPT_USE_OF_DEPRECATED_PROJ_API_H" argument to both CFLAGS and CXXFLAGS.
Thanks for keeping CDO on a par with all the up-to-date software out there.
Cheers,
Thiago
