Run the examples using cargo run --example <example>
Gmsh is a shared resource, and Rust tests run in parallel by default, so cargo test
alone will crash.
Run the tests using cargo test -- --test-threads=1
You can make an alias for this command in your ~/.cargo/config file:
[]
= "test -- --test-threads=1"
Linking to the Gmsh library
Gmsh ships prebuilt binary SDK libraries for Linux, MacOS, and Windows.
The download server is: http://gmsh.info/bin/
Download a recent version and make sure the filename ends with sdk.
Linux
Place all dynamic library libgmsh.so* files where the linker can find them.
Windows
Gmsh is built by MinGW on Windows, not the Visual Studio toolchain.
Because of ABI differences, the easiest way to link your Rust programs to Gmsh is to use the x86_64-pc-windows-gnu target and stable-gnu toolchain.
rustup default stable-gnu
Then, download the Windows SDK zip file and ensure the linker can find the library.
If it can't, you'll get large scary errors when you run cargo test -- --test-threads=1
One way to make sure the linker can find Gmsh is copying the .lib and .dll files to your rustup directory, e.g.:
~\.rustup\toolchains\stable-x86_64-pc-windows-gnu\lib\rustlib\x86_64-pc-windows-gnu\lib
