Hiredis: undefined reference to `hi_malloc(unsigned long)'

[DoctorUSB]

I recently used hiredis in a project and made it into a docker image, the docker image was used in the project and worked fine, this was 2 months ago 17th of December. I recently changed a flag for OpenCV in the original Dockerfile and recreated a new image, I now seem to have a error as seen, below. I believe this may be because my Dockerfile clones the current hiredis repo with the new changes, and a new change may have caused this bug/error. Please note I get this error when just importing redis and not even using it.

/tmp/ccd0E4XK.o: In function `redisLibevAttach(ev_loop*, redisAsyncContext*)':
/usr/local/include/hiredis/adapters/libev.h:122: undefined reference to `hi_malloc(unsigned long)'

Can you try again? I merged a few housekeeping fixes that are likely related to your issue.

Hi Michael thanks for the reply and changes although, I am still having the issue with the latest commit. Thanks.

Perhaps it's attempting to link to an older version of hiredis? I bumped the version to 0.15.0 in this repo as we'll need to do that before any official release.

It's hard to say for sure without a Dockerfile that lets me replicate the problem, but this error is _exactly_ what I would expect when attempting to link to an older version of libhiredis.so.0.14.

If you can provide a Dockerfile to replicate the issue I'm happy to help.

@DoctorUSB Are you still having issues?

[michael-grunder]

I'm going to close the issue because there hasn't been any activity but if you're still running into problems please reopen and let me know.

my temporary fix:

// wsl2 you suck...
void *hi_malloc(unsigned long size){
return malloc(size);
}
