Cannot compile 0.3.7 in portable mode

[GaroRobe]

I'm adding dependence on ursa like:
ursa = { version = "=0.3.7", default-features = false, features = ["portable"] }
Only to get the following error:

Is there something I'm missing maybe or it's planned to fix?

[brianorwhatever]

I am getting this issue as well. @mikelodder7 would you be able to help me get this portable build working easily or is there big problems here?

[txq-bug]

i want to know if replace libsecp256k1 with k256 crate, will this change affect oher work?

[berendsliedrecht]

This should be fixed by #217
