Doesn't seem to register HDF5 1.14.2 as a version.

[trippalamb]

Had to roll back to 1.10.10 in order for hdf5-sys to register a version of HDF5 during the cargo build process.

[mulimoen]

Do you have the version string? In #243 I saw and implemented support for strings like 1.14.1.2

[TrippLamb]

I'm sorry. I don't understand what that means.

[mulimoen]

If you look in the H5pubconf.h header of the install, what is the value of H5_VERSION?

[trippalamb]

It is the same as this issue title "1.14.2"

/* Version number of package */
#define H5_VERSION "1.14.2"

I'm having the same problem. On Arch linux 6.5.8 with the latest hdf5 1.14.2-1 package installed, cargo fails when building a project with hdf5 0.8.1 as a dependency. cargo build ends with the following error:

  Found HDF5 pkg-config entry
      Include paths:
      - "/usr/include"
      Link paths:

My /usr/include/H5pubconf.h header also reports version 1.14.2, same as @trippalamb:

#define H5_VERSION "1.14.2"

[mulimoen]

Are you using the version from crates.io or using themaster branch from here?

[loenard97]

I was using cargo add hdf5, so the crates.io version. I tried again with the latest version from here and it works now. Thank you.

[mulimoen]

@aldanor Maybe we should release a new version soon?

[nleroy917]

I'm having this problem as well on an M1 mac:

        Setting HDF5 root from environment variable:
            HDF5_DIR = "/opt/homebrew/opt/hdf5"
        Custom HDF5_DIR provided; rpath can be set via:
            RUSTFLAGS="-C link-args=-Wl,-rpath,/opt/homebrew/opt/hdf5/lib"
        On some OS X installations, you may also need to set:
            DYLD_FALLBACK_LIBRARY_PATH="/opt/homebrew/opt/hdf5/lib"
        Parsing HDF5 config from:
            "/opt/homebrew/opt/hdf5/include/H5pubconf.h"
      
        --- stderr
        thread 'main' panicked at ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/hdf5-sys-0.8.1/build.rs:200:21:
        Invalid H5_VERSION: "1.14.2"

I've attempted setting those flags as suggested in the error.

[loenard97]

@nleroy917 try to set the hdf5 dependency to the git repo in your Cargo.toml. That did it for me.

[dependencies]
hdf5 = { git = "https://github.com/aldanor/hdf5-rust.git" }

[nleroy917]

I just saw your comment above. Thank you, I will try this. I'm actually getting this build error in someone elses project, so I need to do a clone, change the Cargo.toml, then try a custom build... will report back...

[mulimoen]

@nleroy917 Is it possible to add an override? https://doc.rust-lang.org/cargo/reference/overriding-dependencies.html

[nleroy917]

😱 That worked super well. Even better since hdf5 was going to be a dependency of a dependency. I've got another problem now about not having a threadsafe version of hdf5 installed, but I think that one is unrelated to this issue 😅

[mulimoen]

Could be easier to use the static version of hdf5, try enabling the static feature (still only in master).

[nleroy917]

Oh, it looks like its actually an issue with hdf5-sys:

thread 'main' panicked at ~/.cargo/git/checkouts/hdf5-rust-c1072d7a2617f7d8/26046fb/hdf5-sys/build.rs:697:17:
        Enabled feature "threadsafe" but the HDF5 library was not built with HDF5_ENABLE_THREADSAFE
        note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

Interestingly, I don't even have threadsafe set:

[patch.crates-io]
hdf5 = { git = "https://github.com/aldanor/hdf5-rust.git" }
hdf5-sys = { git = "https://github.com/aldanor/hdf5-rust.git", features = ["static", "zlib"]}

[TrippLamb]

@nleroy917 try to set the hdf5 dependency to the git repo in your Cargo.toml. That did it for me.

[dependencies]
hdf5 = { git = "https://github.com/aldanor/hdf5-rust.git" }

If I do this, it breaks my dependency on hdf5-sys. Is there a way to adjust for this? I'm reasonably new to rust and don't have a great grasp on the way the cargo works.

[mulimoen]

@trippalamb Add another line with hdf5-sys and the same contents

[TrippLamb]

That did indeed seem to fix it. I appreciate it.

[nleroy917]

I was able to solve my problem by just unset-ing my HDF5_DIR variable. I have it in my .zshrc since I need it so often, but this time it was causing problems I guess.
