Following Adnan post (September), I also encounter the issue "unable to
extract profile paths", related to the gcc embeded
into odb-2.3.0-i686-macosx archive. This gcc also seg fault on OSX 10.10.

I dont want to install specific gcc and compile everything from scratch
(too cumbersome for the users). Is a workaround or a new version available

thanks you,

Ok, this is interesting. We build both ODB and GCC on a really old
MacOS X version so that it works everywhere. Until now this worked
quite well. So I will have to look into this. Can you tell me what
was the version of MacOS before you upgraded (and where ODB worked

'g++' that ships with XCode is actually Clang. This won't work with

So the two options are:

1. Wait for me to figure out and hopefully fix the pre-built
   package. I won't be able to look into this until the end
   of the week (I am currently travelling from CppCon).

2. Build GCC and ODB from source yourself.

   As was recently reported by several users, this is actually
   quite easy. Here are the instructions from Bruce Cresanta:


Just to expand on building from source, make sure you are using
GCC 4.8.X and not 4.9.X (vanilla ODB 2.3.0 is not compatible with
GCC 4.9; this is fixed for the next release and there are patches
but I don't think it is worth the trouble patching 2.3.0 in most

Let's say you want to install ODB to /opt/odb-2.3.0. First,
download and build GCC (we install it to /opt/gcc-4.8.3):

./configure --prefix=/opt/gcc-4.8.3 --enable-plugin
sudo make install

At this point check that the GCC compiler is functional by
trying to compile a test program:

/opt/gcc-4.8.3/bin/g++ -c hello.cpp

Then download and build the ODB compiler:

./configure CXX=/opt/gcc-4.8.3/bin/g++
sudo make install

Of course you can change the installation directories to something
else (e.g., /usr/local). Let us know how it goes.
