Link errors building on Windows 10

spacioustime opened this issue 3 years ago · 9 comments

OS: Windows 10
Used OSGeo4W Setup to get proj-devel 8.1.0-1
Generator VS Build Tools 2019 x64

I set PROJINC and PROJLIB explictly

I get:
cmake --build target/cmake

Answer 1 · 2023-02-22T06:51:11.000Z

Hi, I've set PROJLIB to \lib\proj.lib. This worked.

Answer 2 · 2023-02-22T08:32:18.000Z

Thanks for the update. I will close this issue then.

Answer 3 · 2023-02-22T09:32:55.000Z

BTW: Using PROJ-JNI on Windows requires additional setup:
For compilation you need to set PROJLIB and PROJINC manually since 'find_library(PROJLIB proj)' doesn't seem to work here.
For runtime you also need to load all libraries that proj-binding.dll depends on (proj_9_1.dll, sqlite3.dll etc.) via System.load("...").

Answer 4 · 2023-02-22T20:35:59.000Z

Thanks for the clarification. For PROJLIB and PROJINC, would it be possible to provide an example that we could put in the README? And regarding System.load(…), I do not have in mind the exact sentence used in the code, but could you provide an example as well so we can compare with what the code currently does?

Answer 5 · 2023-02-23T10:19:13.000Z

I'm not very familiar to cmake so I've patched CMakelist.txt like this:

...
# We want the "local/lib/" directory to be checked first in order to link against the PROJ version compiled
# locally. Otherwise the PROJ version installed by the package manager may have precedence on Linux systems.
# CMake searches the path in the desired order when using this directive.
find_library(PROJLIB proj)

# set it explicitly on Windows because find_library() doesn't seem to work here
set (PROJLIB $ENV{OSGEO4W_DIR}/lib/proj.lib)
set (PROJINC $ENV{OSGEO4W_DIR}/include)

and provide OSGEO4W_DIR as env-variable at command line. But may be there es better solution. I think it could also be provided via command line parameter to cmake like this:

cmake ... -DPROJLIB=... -DPROJINC=...

but then you need to patch the Ant-file build.xml.

Regarding the System.load("..."):
org.osgeo.proj.NativeResource loads only proj-bindung.dll from the Jar in its static{} block. I've added to my code the following before NativeResource is used:

System.load("/path/to/sqlite3.dll");
System.load("/path/to/libcurl.dll");
System.load("/path/to/zlib1.dll");
System.load("/path/to/jpeg62.dll");
System.load("/path/to/lzma.dll");
System.load("/path/to/tiff.dll");
System.load("/path/to/proj_9_1.dll");

where "/path/to" is also a temporary directory that is created when the DLLs are unpacked from my Jar like proj-bindung.dll.

Answer 6 · 2023-02-23T11:48:54.000Z

Is the above section about accurate?

https://github.com/OSGeo/PROJ-JNI/wiki/Install#build-and-run-in-windows-environment

Answer 7 · 2023-02-23T11:53:44.000Z

It's not necessary to patch NativeResource. Loading the DLLs can be done also outside PROJ-JNI anywhere in the application before PROJ-JNI is used. But the description is fine, I think.

Answer 8 · 2023-02-23T12:03:35.000Z

Thanks for the review. Updated the wiki accordingly.
