Hi Sarah, Thank you for improving our gmnisrv package! > + #:make-flags '("CC=gcc"))) This should be (list (string-append "CC=" ,(cc-for-target))) so that the package cross-compiles correctly. Hard-coding CC=gcc is now deprecated practice. I also feel that this patch should be split into at least two patches or maybe even three. This way, the first line summary in the commit message is much more descriptive of the change. 1. gnu: gmnisrv: Remove dependency on /etc/mime.types. 2. gnu: gmnisrv: Cross-compile. 3. gnu: gmnisrv: Disable tests using tests?. WDYT? Feel free to combine patches 2 and 3 if that splitting is a bit excessive. Thanks, Arun
