32bit build support

[juntyr]

What happened?

I'm trying to build odc on a 32bit system, where the size of the long type is 32 bits, not 64 bits as required.

Using an OS-dependently-sized type but requiring a specific size feels like the wrong solution. Would it be possible to use int64_t instead?

What are the steps to reproduce the bug?

Build on a 32bit system

Version

v1.5.2

Platform (OS and architecture)

Emscripten

Relevant log output

Hey @juntyr, could you give me the exact error message that you get? And could you let me know roughly what build process you're using so I can attempt to reproduce it?

[juntyr]

The following check fails:

odc/CMakeLists.txt

Line 38 in fd66f61

message( FATAL_ERROR "operating system ${CMAKE_SYSTEM} (${EC_OS_BITS} bits) and sizeof long [${__sizeof_long_final}] -- long must be 64 bits exactly" )

I’m trying to build odc for 32bit WebAssembly using Emscripten, as part of porting the codc package (sibling to pyodc) to Pyodide (Python in WebAssembly).

Happy to try to help on this but I fear the issues might go further up the stack.

Could you give me the exact command and CMakeLists.txt you're using? And did you manage to first compile eckit to WebAssembly?

I had a go at reproducing by just commenting out the checks on long and double, intending to then try a global replace of long -> int64_t to see what would break. However, I couldn't get eckit to compile. I used:

export ECBUILD_DIR=/path/to/ecbuild/bin # clone from https://github.com/ecmwf/ecbuild
emcmake cmake -S . -B build -DENABLE_MPI=OFF -DDISABLE_OS_CHECK=ON -DCMAKE_MODULE_PATH=$ECBUILD_DIR/cmake
cd build
emmake make

with CMakeLists.txt:

cmake_minimum_required( VERSION 3.12 FATAL_ERROR )
find_package( ecbuild 3.7 REQUIRED HINTS ${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_SOURCE_DIR}/../ecbuild)
project( Bundle VERSION 0.0.1 LANGUAGES C CXX )

ecbuild_bundle_initialize()
ecbuild_bundle( PROJECT eckit           GIT "[email protected]:ecmwf/eckit"                     BRANCH develop  UPDATE)
ecbuild_bundle( PROJECT odc             SOURCE "./odc")
ecbuild_bundle_finalize()

but I'm not well versed in emscripten so maybe you have already gotten further than this.

[juntyr]

Thank you for looking into this! I made some progress as well, on the https://github.com/climet-eu/pyodide/tree/libodc branch, which includes small patches to make eckit and libodc "just build" as far as I can. You can reproduce as follows:

1. git clone https://github.com/climet-eu/pyodide.git -b libodc
2. docker build .
3. PYODIDE_DOCKER_IMAGE=$(docker build -q .) ./run_docker
4. PYODIDE_PACKAGES="libodc" make

This now fails (you can find the error log at pyodide/packages/libodc/build.log) with:
