wrapper: failed with: gRPC call failed: Socket closed

[manorit2001]

Describe the bug bear doesn't run at all and shows this error while trying to run it.

To Reproduce Not really sure on this part, I have installed bear on ubuntu 22.04 using apt. I even tried compiling from source with the master branch from github but still the same error.

$ bear -- make BUILD_BASE=/home/user/Projects/atf/build CROSS_COMPILE="aarch64-none-linux-gnu-" PLAT=k3 TARGET_BOARD=generic "SPD=opteed" "DEBUG=1" -C atf all               [16:24:09]
wrapper: failed with: gRPC call failed: Socket closed

Expected behavior Generate compile_commands.json

Environment:

• OS name: Linux
• OS version: Ubuntu 22.04
• OS architecture: x86_64
• Bear version: 3.0.18, git-master
• Bear install method: Both compiling from source and apt

Additional context

• Can you give us a reference to the project that you are running against this tool? [e.g. No if it's a close source project, but in case of an open source project a link to the sources could be nice.]: https://github.com/ARM-software/arm-trusted-firmware
• What build tools this project is using? [e.g. GNU make wtih configure script]
• What architecture you are trying to compile for? [e.g. cross compiling]

$ aarch64-none-linux-gnu-gcc --version                                                                                                                                           [16:27:28]

• Could you attach build logs? If you can re-run the command which failed (e.g. bear -- make) with extra verbose log switches (e.g. bear --verbose -- make) and send the output of it, that would help a lot.

Before you send...

• Have you read the README.md file or man bear? Yes
• Have you looked what other open issues Bear has? Yes
• Are you sure that the build works without Bear? Yes

Hey @manorit2001, thanks for the report...

Could you check if the #472 workaround can be applied for your case? (Using wrapper mode, create a wrapper file for the cross compiler and write a configuration file.)

I have to say that your error message is very different (socket closed is something to do with networking), but the cross compiler usage is very much alike. Maybe check if the host you are running the compilation has IPv4 address (localhost is fine).

Hi, I have created softlinks as mentioned in that. Although I couldn't figure out how to create the config file but I can see the cross compiler mappings available. I hope it is fine.

Am not sure what you mean by this, though I agree that the error feels very weird for me too. Wasn't expecting some networking error while using bear.

Though I have a ipv4 localhost address, let me know if I am looking at things wrong.

Though there are some additional logs in verbose mode which might be of interest. Let me know if that helps you figure out the problem.

I am on an internal VPN btw, do you think that might affect the working of bear in any way?

[rizsotto]

VPN should not be an issue. It's about to have an IP address...

Can you test Bear on your machine with a non-cross compiling project? I am curious if that's making the issue or not. (I am testing against the zlib project in the CI job. So, that should go well.)

[rizsotto]

Any luck @manorit2001 ?

[manorit2001]

Ah yes, sorry for the late reply. It seems like it was a VPN issue only am not sure how, as soon as I removed all the proxy variables and tried to connect without VPN it got resolved.

I didn't try the other thing you mentioned as it started working for me without VPN.

[zhijie-zhang]

maybe used https_proxy/http_proxy

[q2333gh]

export https_proxy=
export http_proxy=

do this will temporary disable vpn. and bear works well for me !

for example i use :

make clean && bear -- make qemu

it generate compile_commands.json good!
