gdal.netcore Errors when adding NetCDF

For a project I need to process GRIB and NetCDF files. I can read the GRIB files but for the NetCDF files I have to add a driver. But when I compile it for unix I get the following error after running make -f gdal-makefile:

./.libs/libproj.so: undefined reference to `curl_easy_getinfo'

I've installed CentOS7 on WSDL2 (from here) and after that I've followed the instructions which are mentioned here.

It might be caused by permission issues because at the beginning I get the following errors:

./configure: line 18494: /root/gdal.netcore/unix/../build-unix/vcpkg/installed/x64-linux-dynamic/share/curl/curl-config: Permission denied
./configure: line 18495: /root/gdal.netcore/unix/../build-unix/vcpkg/installed/x64-linux-dynamic/share/curl/curl-config: Permission denied

./configure: line 18551: /root/gdal.netcore/unix/../build-unix/vcpkg/installed/x64-linux-dynamic/share/curl/curl-config: Permission denied

I'm logged in as the root user and I cloned the source in the /root folder.

Besides that, I had to manually install patchelf by using yum -y install https://download-ib01.fedoraproject.org/pub/epel/7/x86_64/Packages/p/patchelf-0.12-1.el7.x86_64.rpm

Can you help me getting the compilation to work for me and possibly give me some directions to add the NetCDF driver?

The permissions problems have to do with curl-config not getting executable flag.. not sure why, seems like a clear bug somewhere. Workaround is to set it manually i.e chmod +x gdal.netcore/build-unix/vcpkg/installed/x64-linux-dynamic/share/curl/curl-config.

Thanks for the quick reply. Manually chmod the folder did the trick.

About permissions, try to run a command with sudo, e.g. sudo make -f gdal-makefile or change working directory.

NetCDF driver (also libkml, hdfs3) requires boost dependencies, that's more than 140 additional packages. Just start with shared/GdalCore.opt. Enable driver in config, rebuild VCPKG's packages and try to build GDAL bindings.

Closing due to inactivity.

Due to holidays and finishing projects I wasn't able to work on this for a while. However, this week I had some time.

I've added netcdf-c to the VCPKG_REQUIRE line (shared/GdalCore.opt): VCPKG_REQUIRE=tiff expat xerces-c libpng libiconv zlib netcdf-c

After that I've installed the netcdf-devel library: yum install netcdf-devel -y

The following libraries are now installed:

I've enabled the driver in the GDAL config (gdal-makefile): --with-netcdf=${VCPKG_INSTALLED} \

Rebuilding all the packages with make -f vcpkg-makefile was successful:

This seems that it has something to do with SSL? I've installed the openssl-devel library which is version OpenSSL 1.0.2k-fips 26 Jan 2017

Aug 11 '21 08:08 rolftimmerman

Yes and no, for ssl. PROJ uses curl library with internal ssl from vcpkg. It can be some issue with cached link symbols. Please, try to rebuild PROJ with cleanup. make -f gdal-makefile reset_proj configure_proj build_proj

I've tried your solution but I got the same error unfortunately.

Aug 11 '21 12:08 rolftimmerman

You can check that symbol (OPENSSL_sk_num) is not available in older one. So it seems like there is some collision between package versions. Probably, PROJ uses your OpenSSL 1.0.2k-fips 26 Jan 2017, but the latest from vcpkg is 1.1.1k. Can you update or delete your ssl (from user)?

I've updatet OpenSSL to version 1.1.1k but I still receive the same error. Even after rebuilding the vcpkg packages. Maybe next week I will try to compile from a fresh CentOS 7 system without NetCDF and see if that works first.

I've installed a fresh CentOS 7 WSL system, updated it and installed everything according to the Unix Readme. Everything compiles succesfully and I can generate the bindings and create the packages.

After that, I've added netcdf-c to the VCPKG_REQUIRE line in the shared/GdalCore.opt file (VCPKG_REQUIRE=tiff expat xerces-c libpng libiconv zlib netcdf-c) and ran make -f vcpkg-makefile all. This installed NetCDF successfully:

However, when I ran make -f gdal-makefile force I still get the same errors as mentioned above.

Those errors are referred to PROJ library, there's nothing about NetCDF. What are the latest logs? Are they identical to above errors?

Please, If you post large logs here, use a spoiler or attach a file.

That's what it makes weird right? When removing netcdf-c from the line VCPKG_REQUIRE=tiff expat xerces-c libpng libiconv zlib line in the shared/GdalCore.opt file everything builds without any errors. But when I add netcdf-c, running make -f vcpkg-makefile succesfully builds and installs the libraries (vcpkg-makefile-netcdf.log), but when running make -f gdal-makefile I get the same ./.libs/libproj.so: undefined reference errors (gdal-makefile-netcdf.log).

Closing this as netCDF driver is available in the latest release 3.6.0.
