I always compiled Bitcoin from git, but now I get the following error (I'm using libtool 2.4.2):

CXXLD test/test_bitcoin CXX qt/qt_bitcoin_qt-bitcoin.o OBJCXXLD qt/bitcoin-qt libtool: link: unable to infer tagged configuration libtool: link: specify a tag with `--tag' Makefile:2305: recipe for target 'qt/bitcoin-qt' failed make[1]: *** [qt/bitcoin-qt] Error 1 make[1]: Leaving directory '/usr/local/src/git/bitcoin/src' Makefile:551: recipe for target 'all-recursive' failed make: *** [all-recursive] Error 1
```
Any hints? Thanks.

@theuni Can you have a look here?
theuni commented at 12:39 AM on September 30, 2014: member

what OS and toolchain? Could you please redo the above using "make V=1" and paste that, so we can see what's going on?
theuni commented at 12:40 AM on September 30, 2014: member

ah wait I see, it's probably that pesky OBJCXXLD that @luke-jr mentioned a while ago. I'll track down the cause of that and fix it, and I'm guessing it'll fix your problem as well.

@DanielFragaBR Would you mind seeing if this fixes your build problem?

I'm not sure what the cause is just yet, but I believe that should cure the symptom.

@theuni yes, this patch solved the problem! Thanks!

@DanielFragaBR Please reopen. I'd like to track down why this is happening and push a real fix (or at least this work-around) before we call this closed.

Thanks for reporting and testing.

@theuni thanks. If you need more testing, just ask.

@DanielFragaBR Thanks. Could you please pastebin your config.log? I suspect that we're picking up something from the environment. I'm assuming you're on osx, btw? Do you happen to dev on other projects that require env changes?
DanielFragaBR commented at 5:55 PM on September 30, 2014: none

@theuni you're right! I messed with the environment with the CXX flag the wrong way. Now I fixed that. So I'm closing this entry.

Thank you very much!

Great, now we know. Thanks for confirming.

@DanielFragaBR Could you elaborate on what you'd done to your environment to cause this error? I'm seeing the same thing on another machine.
DanielFragaBR commented at 3:42 PM on October 13, 2014: none

@fanquake I put some flags in CXX environment variable which shouldn't be there. Maybe it's not your case. Now I just use the correct LDFLAGS and CPPFLAGS. What flags are you setting?
theuni commented at 6:21 PM on October 13, 2014: member

@fanquake It'll be CC or CXX that's set. That causes automake's tag deduction to fail for OBJCXXLD. Since several people are seeing this now, I suppose it's best to go ahead and push the work-around while we track down the real culprit. Could you please verify that #4993 (comment) works for you as well?

@theuni That fix works fine.
