@Dgraph_Admin any update on this? @Vishal_Jangid did you get the compilation issue fixed? I am also facing the same issue but on MacOS. ---

I was unable to resolve the issue on Rhel 7. I haven’t tried it on MacOS. ---

Hi Abdul, did you use the makefile in badger to install jemalloc? Try running `make badger` and let us know what happens. Badger compiles with jemalloc on my MacOS machine. @Vishal_Jangid I can’t speak personally for RHEL but I’d suggest the same advice to compile with `make badger` and report back what happens. ---

Hi @joshua, I cloned the `dgraph-io/badger` repository and executed `make badger` command which resulted in same error: ```auto Compiling Badger binary... # github.com/dgraph-io/ristretto/z /go/pkg/mod/github.com/dgraph-io/ristretto@v0.1.1/z/calloc_jemalloc.go:73:9: could not determine kind of name for C.je_calloc /go/pkg/mod/github.com/dgraph-io/ristretto@v0.1.1/z/calloc_jemalloc.go:103:3: could not determine kind of name for C.je_free /go/pkg/mod/github.com/dgraph-io/ristretto@v0.1.1/z/calloc_jemalloc.go:143:2: could not determine kind of name for C.je_mallctl /go/pkg/mod/github.com/dgraph-io/ristretto@v0.1.1/z/calloc_jemalloc.go:170:2: could not determine kind of name for C.je_malloc_stats_print make[1]: *** [badger] Error 2 make: *** [badger] Error 2 ``` It would be awesome, if you can guide us with the exact steps on how to build DGraph with MacOS and explicitly mention any external dependencies required separately. Thanks! ---

Hi @Abdul_Aziz , Sorry for the delay. That is interesting - usually this error comes the Cgo preamble being misconfigured (e.g. see [here](https://github.com/golang/go/issues/9733)) but it doesn’t look like that is the problem here. Could you try running `go install github.com/dgraph-io/badger/v4/badger@latest`? This should also install the Badger CLI. Alternatively, if you want to build the CLI locally, you can try running `go build .` from the Badger subdirectory. To be clear, if your goal is to build Dgraph from source, you don’t have to first build Badger, since this is just a CLI for debugging (Badger is an embedded key-value store). Instructions for building Dgraph are in the Dgraph readme.
