fatal error: '../graal/dxfg_api.h' file not found

[princefishthrower]

Hi all interested in getting some dxfeed examples running in Go. I just created an empty project with a main.go and the library installed via go get github.com/dxfeed/dxfeed-graal-go-api

As the title states, when I try the QD Endpoint or DxLink example code snippets, I get the following:

go run main.go 
# github.com/dxfeed/dxfeed-graal-go-api/internal/native/mappers
../../../go/pkg/mod/github.com/dxfeed/dxfeed-graal-go-api@v0.0.0-20240614163323-4228e362dba3/internal/native/mappers/analytic_order_mapper.go:4:10: fatal error: '../graal/dxfg_api.h' file not found
    4 | #include "../graal/dxfg_api.h"
      |          ^~~~~~~~~~~~~~~~~~~~~
1 error generated.

I am on mac OS, apple silicon (M3). I have clang installed:

clang --version

Apple clang version 16.0.0 (clang-1600.0.26.6)
Target: arm64-apple-darwin24.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

Did I miss a prerequisite or additional install step? Thanks a lot!

Hello @princefishthrower!
Yes, this project requires an additional binary dependency (it uses the cgo mechanism).
Please try running these commands:

git clone git@github.com:dxfeed/dxfeed-graal-go-api.git
cd dxfeed-graal-go-api
go run .
go run cmd/samples/print-quote-events/main.go

The go run . command executes install_dependencies.go, or you can manually download graal-native-sdk-1.1.6-aarch64-osx.zip and extract it to dxfeed-graal-go-api/internal/native/graal (in this case, you'll have to remove the quarantine attribute: sudo /usr/bin/xattr -r -d com.apple.quarantine dxfeed-graal-go-api/internal/native/graal/libDxFeedGraalNativeSdk.dylib)

Hello,

I’m on windows and I had the same issue.

I did the commands you provided and it’s a little better however I can’t run the sample script.

$ go run cmd/samples/print-quote-events/main.go 
exit status 0xc0000135

Hello @Scorfly!
Could you please try installing the Visual C++ Redistributable?

[Scorfly]

Thx for this fast answer.

It changed nothing on my side :(

[stdcion]

Do you have a 64-bit windows? What version do you have?

[Scorfly]

Yes it’s a 64-bit windows version 10.

Hmm, can we try running the utility app we've already built:

Oh, I think I get it, dll location issues on windows.
please, go to dxfeed-graal-go-api\internal\native\graal and and try running it from there.

cd internal\native\graal\                       
go run ../../../cmd/samples/print-quote-events/main.go

You can configure an IDE like Goland to copy the required dll to the output directory.

Thx ! It’s working now 👍
