# netmap_sys
Rust bindings to [netmap](http://info.iet.unipi.it/~luigi/netmap/), currently
at version 3.17 (Linux).
## Usage
To use within your own project, add:
```
[dependencies.netmap_sys]
git = "https://github.com/libpnet/netmap_sys.git"
# Uncomment this line where you wish to use features guarded by the
# NETMAP_WITH_LIBS macro in C.
#features = "netmap_with_libs"
```
To your Cargo.toml.
## Troubleshooting
### missing rust_netmap_user
If you get an error containing the message:
```
error: could not find native static library `rust_netmap_user`, perhaps an -L flag is missing?
```
You should check the following things:
1. You have clang installed
* If you do not have clang installed, and do not wish to, you can modify
`build.rs` to use gcc instead (untested, but it should work).
2. Make sure that `/usr/include/net/netmap.h` and
`/usr/include/net/netmap_user.h` both exist. If they do not, you should
check your netmap installation. You can either manually add these files or
symlinks to the, or change the paths searched in `build.rs`.
3. If you still have issues, please file an issue in the bug tracker, along
with the output of `cargo build -v`, your operating system and distribution,
how you installed netmap, and the output of `clang -DNETMAP_WITH_LIBS
-Dstatic= -Dinline= -x c -fPIC -O2 -c /usr/include/net/netmap_user.h -o
$(mktemp)`.
