Build: configure --disable-optimize-llvm

[pnkfelix]

I am on OS X, 10.7.5, Xcode 4.6.

My original goal was to configure a Rust build with "maximal debugability"; so I ran this:

% git log -1 --oneline
19dfec2 auto merge of #4852 : Caseus/rust/issue-4836, r=brson
% mkdir objdir-dbg; cd objdir-dbg
% ../configure --enable-debug --disable-optimize{,-cxx,-llvm}

The configure finished, but then when I ran make, I got an error that said something about llvm-config

After seeing that, I guessed that llvm is the problem, so maybe the llvm-related flag I fed to configure is not supported with those other options.

So then I just tried this:

% ../configure --disable-optimize-llvm

It has the same error; this error:

...
 llvm[3]: ======= Finished Linking Release+Asserts Unit test VMCore (without symbols)
llvm[1]: ***** Completed Release+Asserts Build

Couldn't reproduce this on Linux, is this Mac-only?

[bstrie]

To elaborate, I successfully completed a ./configure --disable-optimize-llvm && make. Didn't run the test suite (four hours to build without opts was long enough), but I gather that the bug seen here wasn't even getting that far.

Still cannot reproduce on Linux.

[pnkfelix]

I'll assign this to myself, to check (1.) whether I can still reproduce on Mac, and (2.) whether I cannot reproduce on Linux.

looks to me like this is no longer reproducible, even on mac. (perhaps there was some bug in our or LLVM's make that has since been fixed; or perhaps my bug description was incomplete, or my build environment at the time was hosed.)
