Can you show me the link of the libcairo conflict example you said? I don't know what cause the segfaults in your example. C linker will embed the full path of the library into the RUNPATH, unless LD_LIBRARY_PATH is set, C library will use the dependencies they found in link time. >>=20 >> i've asked in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=3D44327=C2= =A0and >> suggest to introduce priority mechanism like Nix.

'priority' will let user to specify which package can override other packages, if some of their contents overlapped with each other. Now Guix will silently choose one.=20 =2D-=20 Retrieve my PGP public key: gpg --recv-keys D47A9C8B2AE3905B563D9135BE42B352A9F6821F Zihao --=-=-= Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iIsEARYIADMWIQRefA5qkqvnKdl/GTlmOX+E92aT+QUCYi4EXxUcYWxsX2J1dF9s YXN0QDE2My5jb20ACgkQZjl/hPdmk/nA/AD/c5hEt+ZoGk7T3xqbOQMps1HtBGpm QMrdQD3bQo7HowMA/iMKJh9ePpCrlPYpMLSTLSerJE6OWDIk9Xm58W6iatkO =Zb9q -----END PGP SIGNATURE----- --=-=-=--
