Bug #10409

Can't build Ruby checked out from official GitHub mirror

Added by imasahiro (Masahiro Ide) over 5 years ago. Updated over 5 years ago.

Target version:
ruby -v:
ruby 2.2.0dev (2014-10-21 trunk 48070) [i686-linux]


When I tried to compile official github mirror version of ruby on linux system, I get the error:

$ ./configure
checking for broken memmem... no
checking for nroff... /usr/bin/nroff
.ext/include/i686-linux/ruby/config.h updated
ruby library version = 2.2.0
configure: creating ./config.status
config.status: creating GNUmakefile
config.status: creating Makefile
config.status: creating ruby-2.2.pc
Downloading Unicode data files...
ruby: Can't chdir to ../enc/unicode/data (fatal)
make: *** [update-unicode] Error 1

This error happens only in the git version because git don't track emtpy directories ("$(srcdir)/enc/unicode/data").

The following patch may fix this problem.
