To build Swift on ArchLinux you will need to install the perl package which includes pod2man. I think the list of dependencies at https://swiftenv.fuller.li/en/latest/building-swift.html#arch-linux is correct and should contain everything you need.
$ pacman -S perl libbsd icu git libedit python2 clang make ninja
Hope this helps,
I am hoping someone would be able to help with the following problem:
I am trying to build Swift 3 under ArchLinux. I have followed the build instructions and everything has been cloned and kick off the build by typing: ./swift/utils/build-script -R
After a long while the build errors out at (emphasis mine):
copying static files... done
copying extra files... done
dumping search index in English (code: en) ... done
dumping object inventory... done
[574/574] Generating swift.1

Can't open swift: No such file or directory at /usr/bin/core_perl/pod2man line 70.
ninja: build stopped: subcommand failed.
./swift/utils/build-script: fatal error: command terminated with a non-zero exit status 1, aborting
So what am I doing wrong? What can I do to either fix this issue or skip it if it is not essential (i.e. docs, etc.)? Any help and pointers would be greatly appreciated.
