Sf: "proj_api.h not found in standard or given locations" in OSX Mojave

[akhst7]

I had a trouble installing sf through a recommend OSX installation and I tried this CMD Install, command;

R CMD INSTALL ~/Documents/GitHub/sf --configure-args='-with-gdal-config=/usr/local/Cellar/gdal/2.4.1_1/bin/gdal-config -with-geos-config=/usr/local/Cellar/geos/3.7.2/bin/geos-config'

But I am still getting the same error regarding pros_api,

proj_api.h not found in standard or given locations

I have a Brew install PROJ6,

/usr/local/Cellar/proj/6.1.0/bin/cct /usr/local/Cellar/proj/6.1.0/bin/cs2cs /usr/local/Cellar/proj/6.1.0/bin/geod /usr/local/Cellar/proj/6.1.0/bin/gie /usr/local/Cellar/proj/6.1.0/bin/invgeod /usr/local/Cellar/proj/6.1.0/bin/invproj /usr/local/Cellar/proj/6.1.0/bin/proj /usr/local/Cellar/proj/6.1.0/bin/projinfo /usr/local/Cellar/proj/6.1.0/include/proj/ (9 files) /usr/local/Cellar/proj/6.1.0/include/ (7 files) /usr/local/Cellar/proj/6.1.0/lib/libproj.15.dylib /usr/local/Cellar/proj/6.1.0/lib/pkgconfig/proj.pc /usr/local/Cellar/proj/6.1.0/lib/ (3 other files) /usr/local/Cellar/proj/6.1.0/share/man/ (8 files) /usr/local/Cellar/proj/6.1.0/share/proj/ (12 files)

The installer does not see the brew installed proj6 even though /usr/local is ahead in the path. Is it possible to manually set a path to proj6 in CMD Install ?

We need to see the complete output of the configure step.

Here is the output of config.

I'd suggest to update GDAL to 3.0.0, and use that with PROJ 6.1.0.

[akhst7]

can't install GDAL 3.0.0 (from the source). I get the same error;

`checking for PROJ >= 6 library... checking for proj_create_from_wkt in -lproj... yes
checking proj.h usability... no

checking proj.h presence... no
checking for proj.h... no
configure: error: proj.h not found`

[edzer]

Well, that suggests that there is a problem with your PROJ installation, or you need to set --with-proj= arguments. Which might help with sf as well: do run ./configure --help in the sf directory.

Ok I specified a path to pros_api.h as follows;

R CMD INSTALL ~/Documents/GitHub/sf --configure-args='-with-gdal-config=//usr/local/Cellar/gdal/2.4.1_1/bin/gdal-config --with-proj=/usr/local/Cellar/proj/6.1.0/include/proj_api.h -with-geos-config=/usr/local/Cellar/geos/3.7.2/bin/geos-config'

But I am still getting the same error. Any suggestions for a workaround ?

Thanks.

I think it should be --with-proj=/usr/local/Cellar/proj/6.1.0/

[akhst7]

I tried with --with-proj=/usr/local/Cellar/proj/6.1.0/ but still get the same error;

./configure: line 3648: pkg-config: command not found
checking proj_api.h usability... no
checking proj_api.h presence... no
checking for proj_api.h... no
configure: error: proj_api.h not found in standard or given locations.

I did reinstall PROJ6 by brew but the same result.

The problem was not having a pkg-config. After installing it, sf was installed seamlessly.

Thanks.

Had the same issue. After brew install pkg-config, sf was installed. Thanks.
