Failure to build on Linux

[InventoryTech]

I came across your imager project on GitHub while looking at various image compression software. I was able to download and run it on Ubuntu, and it does a fantastic job on compression. Well done on developing this awesome utility!

I am now trying to compile it for a Raspberry Pi but am running into some errors.

I followed the steps in the 'install.md' file in the project:

• curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
• apt-get install -y build-essential llvm-dev libclang-dev clang openssl pkg-config libssl-dev xz-utils
• git clone https://github.com/imager-io/imager.git && cd imager
• cargo install --path imager --force

If I run the compile with the --verbose option I get the following output:

Running `rustc --crate-name webp_dev --edition=2018 /home/pi/.cargo/registry/src/github.com-1285ae84e5963aae/webp-dev-0.4.1/src/lib.rs --error-format=json --json=diagnostic-rendered-ansi,artifacts --crate-type lib --emit=dep-info,metadata,link -C opt-level=3 -Cembed-bitcode=no --cfg 'feature="default"' -C metadata=0d370911ed82618f -C extra-filename=-0d370911ed82618f --out-dir /tmp/cargo-installKBNy5i/release/deps -L dependency=/tmp/cargo-installKBNy5i/release/deps --extern image=/tmp/cargo-installKBNy5i/release/deps/libimage-a4bacbab917eac6b.rmeta --extern libc=/tmp/cargo-installKBNy5i/release/deps/liblibc-5103d3a8c700d90d.rmeta --cap-lints allow -L native=/tmp/cargo-installKBNy5i/release/build/webp-dev-cd4262d980e28f83/out/webmproject-libwebp-8bac456/src -L native=/tmp/cargo-installKBNy5i/release/build/webp-dev-cd4262d980e28f83/out/webmproject-libwebp-8bac456/src/demux -L native=/tmp/cargo-installKBNy5i/release/build/webp-dev-cd4262d980e28f83/out -l static=webp -l static=webpdemux -l static=cbits`

This error happens on the Raspberry Pi and Ubuntu (WSL)

Any advice on how to fix this?

[StevenJiang1110]

I encounter the same issue when I try to build from source, on my x86-64, ubuntu18.04 machine. I don't know how to add the static library dependency. Hope for some advice

I have a similar issue in void linux, where I added libwebp-devel (which should be the equivalent of libwebp-dev in ubuntu), but encountered a fatal error that stddef.h could not be found when it was clearly available.

Getting the same error..

[tbeckley]

Still an issue :(, I have libwebp-devel installed on Fedora 36 but still get the error. No amount of RUSTFLAGS environment variables seems to get it done for me.

PS atk the stddef.h issue I solved by ensuring clang was installed (not just clang-llvm or whatever the other package is called).

[mxdpeep]

• apt-get install -y build-essential llvm-dev libclang-dev clang openssl pkg-config libssl-dev xz-utils

this solved the problem:

sudo apt install libwebp-dev

$ which imager
/home/mxdpeep/.cargo/bin/imager
$ imager --version
imager 0.3.2

[mxdpeep]

sudo apt-get install -y build-essential llvm-dev libclang-dev clang openssl pkg-config libssl-dev xz-utils
sudo apt-get install libjpeg-dev libpng-dev libtiff-dev libgif-dev libwebp-dev
cargo install imager

no errors

rustc 1.65.0 (897e37553 2022-11-02)

Having trouble building this as well:

However, since this repo has been basically unmaintained for the past four years I guess it's time to move on. In case anyone has recommendations for an alternative to imager I'd appreciate it!
