Bug #11913
Updated by mcmire (Elliot Winkler) over 8 years ago
Hi there. I've been trying to submit a bugfix, and in doing so I realized that I had to compile Ruby so that I could run all of the tests. I made make a fresh clone of Ruby, and started following the [Contributing document](https://github.com/ruby/ruby/blob/trunk/doc/contributing.rdoc), but then ran into some issues. These instructions have you run `./configure` from another directory (`build`) that is not the root directory of the repo. Unfortunately, running `make` did not seem to work, and here was the output: ~~~ ± make CC = clang LD = ld LDSHARED = clang -dynamic -bundle CFLAGS = -O3 -fno-fast-math -ggdb3 -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Werror=pointer-arith -Werror=write-strings -Werror=declaration-after-statement -Werror=shorten-64-to-32 -Werror=implicit-function-declaration -Werror=division-by-zero -Werror=deprecated-declarations -Werror=extra-tokens -pipe XCFLAGS = -D_FORTIFY_SOURCE=2 -fstack-protector -fno-strict-overflow -fvisibility=hidden -DRUBY_EXPORT -fPIE CPPFLAGS = -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -I. -I.ext/include/x86_64-darwin15 -I../include -I..

So after running `make clean`, then `mkdir -p enc/trans` from within `build` (as it turns out, `enc/trans` also needed to be present), I then ran `make` again, and got this: ~~~ ± make CC = clang LD = ld LDSHARED = clang -dynamic -bundle CFLAGS = -O3 -fno-fast-math -ggdb3 -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wunused-variable -Werror=pointer-arith -Werror=write-strings -Werror=declaration-after-statement -Werror=shorten-64-to-32 -Werror=implicit-function-declaration -Werror=division-by-zero -Werror=deprecated-declarations -Werror=extra-tokens -pipe XCFLAGS = -D_FORTIFY_SOURCE=2 -fstack-protector -fno-strict-overflow -fvisibility=hidden -DRUBY_EXPORT -fPIE CPPFLAGS = -D_XOPEN_SOURCE -D_DARWIN_C_SOURCE -D_DARWIN_UNLIMITED_SELECT -D_REENTRANT -I. -I.ext/include/x86_64-darwin15 -I../include -I..

After running `./configure` from within the root directory, then `make` worked successfully. So what I suppose is that there's something inside of the makefiles that still makes the assumption that `make` is going to be run inside of the root directory. But that's just a hunch.
