Configuration fails in linking PROJ

[girgink]

On Ubuntu 20.04 I have PROJ installed through apt:

apt list --installed | grep libproj

libproj-dev/focal,now 6.3.1-1 amd64 [installed]
libproj15/focal,now 6.3.1-1 amd64 [installed,automatic]

Running install.packages("gdalcubes", repos = "https://cloud.r-project.org/") gives the following error:

checking gdal.h usability... yes
checking gdal.h presence... yes
checking for gdal.h... yes
checking GDAL: linking with --libs only... yes
checking GDAL: /usr/local/share/gdal/pcs.csv readable... no
checking GDAL: checking whether PROJ is available for linking:... yes
checking GDAL: checking whether PROJ is available fur running:... yes
configure: GDAL: 3.2.3
configure: pkg-config proj exists, will use it
configure: using proj.h.
configure: PROJ: 6.3.1
checking PROJ: checking whether PROJ and sqlite3 are available for linking:... no
configure: error: libproj or sqlite3 not found in standard or given locations.
ERROR: configuration failed for package ‘gdalcubes’

I can confirm that both libproj and sqlite3 are installed properly by using the test code used in the Makefile:

cat > proj_conf_test.cpp <<_EOCONF
#include <stdio.h>
#include <stdlib.h>
#include <proj.h>
int main() {
    proj_context_create();
    exit(0);
}
_EOCONF

g++ -o proj_conf_test proj_conf_test.cpp -lproj -lsqlite3

./proj_conf_test

The code above builds without an error and test exists with code 0 as expected.

Thanks for the report! Hard to say what goes wrong, are you able to install the sf package? Maybe there is more than one version of PROJ (e.g. in /usr/local/lib)?

Thanks for the reply! It looks like the issue was related to the location of PROJ, because it is not under /usr/local/lib, but under /usr/lib/aarch64-linux-gnu. Installation worked properly with the following command:

install.packages("gdalcubes", configure.args = c(gdalcubes = "--with-proj-lib=/usr/lib/aarch64-linux-gnu"), repos="https://cloud.r-project.org/")
