dyld: _cblas_dgemv Error when executing filter

[rabah-khalek]

Anyone familiar with this issue? The filter starts to run normally but then at some point stops and produce this error:

filter is not installed with the conda package anymore (I think), so I am not sure what you are running. Can you try vp-setupfit instead?

[rabah-khalek]

Correct, It's not but I compiled it by changing the configuration of cmake via cmake . and then filter ON. Okay so I shouldn't do that, vp-setupfit works fine. Thanks, I will close this issue.

Anyhow, please have a look here:

#113 (comment)

maybe you need to remove that one flag to get the dev environment to work. @wilsonmr do you have experience setting that up?

[wilsonmr]

Yes actually, it does look sort of familiar to an error I get if I don't remove the -dead_strip_dylibs - as per your comment - when running vp-upload actually.

I'm lazy so I copy and paste this after entering the development environment but before running cmake

nnpdf/conda-recipe/build.sh

Line 2 in 801dfd1

export LDFLAGS=$(echo $LDFLAGS | sed 's/-Wl,-dead_strip_dylibs//g')

[Zaharid]

Yeah, we should document that somewhere in the guide.

[rabah-khalek]

Yes that solves it. Thanks both.
