如何在GO中指向C头文件？

Question

New to GoLang so go easy on me. I installed this package for which are GO bindings for the HDF5s filesystem:

go get github.com/sbinet/go-hdf5

and I get

fatal error: hdf5.h: No such file or directory
// #include "hdf5.h"

the file hdf5.h (which comes from the original hdfs library, not the go package) is located in

usr/include/hdf5s/series

how do I tell the go compiler to look in the /user/include/hdf5s/series directory for this header file?

Answer 1

Pass the -I flag to the C compiler using the CGO_CFLAGS environment variable (documentation):

CGO_CFLAGS="-I/usr/include/hdf5s/series" go get -u github.com/sbinet/go-hdf5
