BUILD FAILED (OS X 10.15.1 using ruby-build 20191124) when installing ruby-2.4.0 with rbenv in OSX catalina(10.15.1)

Question

I tried a lot of things from online forums. But never worked. Installed Xcode to see if it works. But it doesn't.

At first, there was an issue with the C executables at the time of the OpenSSL installation. But later, I found from here, the error occurred because of Anaconda installation. So I uninstalled anaconda and tried to install again.

But now it is throwing a different error.

Did anyone face this problem before? Any help would be greatly appreciated.

UPDATE

Adding the last few lines in the logfile. Most of them look like errors in C lang

Answer 1

First, let trim your log to the significant part:

num2int.c:56:21: error: expected ')'
    sprintf(buf, "%"PRI_LL_PREFIX"d", NUM2LL(num));
                    ^
num2int.c:56:5: note: to match this '('
    sprintf(buf, "%"PRI_LL_PREFIX"d", NUM2LL(num));
    ^
/usr/local/include/secure/_stdio.h:47:27: note: expanded from macro 'sprintf'
  __builtin___sprintf_chk (str, 0, __darwin_obsz(str), __VA_ARGS__)

Basically, this says that there was an error while expanding a macro to some line in file num2int.c. So, where is does that macro come from? The log says that the macro was defined in file /usr/local/include/secure/_stdio.h.

This file correspond to a locally installed package, most probably added through brew (it could also have been installed by some application installed with a package installer, but this appears less probable). I have not found yet to which package that file belongs (don't have it on my computer and havn't found any reference to it on Google), but _stdio.h files are rather exceptionnal, so I believe that it might be related to brew's private GCC. Yet, ruby-build (when executed though rb-env install) prefer to use XCode's clang compiler, which might not support some syntax extension supported by brew's GCC.

In short, you end up loading in Apple's clang some local include file that use some syntax thaat is not compatible with that compiler.

What to do now?

You must determine if the /usr/local/include/secure/ directory is actually useful. Maybe, this is related to a program that you no longer use… I can't tell you exactly what to do about this, but here are some ideas:

• Check if either secure or secure/_stdio.h is a symlink (i.e.: ls -l /usr/local/include/secure/). If they have been installed by brew, they should point to somewhere under ../Cellar/<package-name>. If there are, maybe you could consider uninstalling that package…

• Run brew doctor and check for "Unexpected header files".

Ideally, you want to end up deleting that directory… If you are not certain either it is a good idea, then you may consider moving it temporarilly out of the include directory, for example by doing the following:

mkdir /usr/local/include.disabled
mv /usr/local/include/secure /usr/local/include.disabled/secure

# Compile ruby

mv /usr/local/include.disabled/secure /usr/local/include/secure
rm -rf /usr/local/include.disabled

If none of this works, please post the output of the following commands to a pastebin:

which clang

brew doctor

brew ls

ls -la /usr/local/include

How to move all OSX SDK include files out of local/include

I think the following command should be enough to move all include files pointing to the OSX SDK out of the /usr/local/include directory (my uncertainty here is related to either sub-directories were themselves symlinked, or if it is the content of these subdirectories that is symlinke… I assumed the first, and this oneliner script will miss directories if they are of the second type).

mkdir -p /usr/local/include.disabled/
find /usr/local/include/ -depth 1 -lname '/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/*' -exec mv '{}' /usr/local/include.disabled/ ';'

Run these commands, then execute ls -la /usr/local/include again… There should be much less content in it. Do you still have a secure directory there?

And most importanly, can you now get through your original build?
