18.0.0 is not support with old libsecp256k1

With or without libsecp256k1, I have the following error (it links an internal version of this lib (CC src/libsecp256k1_la-secp256k1.lo ) :

@Ergo: did you try suggestions by @mborder below? Package builds for me.

Still getting the same error:

build/temp.linux-x86_64-3.8/_libsecp256k1.c:541:10: fatal error: secp256k1_ecdh.h: No such file or directory 541 | #include <secp256k1_ecdh.h> | ^~~~~~~~~~~~~~~~~~ compilation terminated. error: command 'gcc' failed with exit status 1 ==> ERROR: A failure occurred in build(). Aborting... Error making: python-coincurve

Thanks! That totally did the trick! Removing libsecp256k1 temporarily and python-coincurve builds fine.

Thank you for looking into this.

I've been debugging this package for a good hour now.

Upstream checks for the lib secp256k1 in a way that can return false positives, basically they only check for the library, not for the feature ecdh which is experimental. Now because ecdh is experimental, it's not included in the package libsecp256k1, and if you have that (or anything else providing it without ecdh) then the build will fail like in sehraf's case. Removing anything providing secp256k1 fixes the issue, however you may need to delete the cached build folder for this, I ended up with an odd error fixed by doing that after discovering the false library version issue.

Also I've filed an issue with upstream.

Still the same :(

@sehraf: appears to be fixed in 13.0.0.

Build fails due to missing secp256k1_ecdh.h
