[lldb-dev] LLDB compile problem: contradicting exception specifications

[Bjoern Kahl]

 Dear All,

 I am trying to build LLDB on Mac OSX Snow Leopard using command line
 build as per instructions from the web page http://lldb.llvm.org/build.html

 Since XCode does not worked for me, I am trying the autotools & make
 based build.

 After checking out llvm and then clang and lldb into the tools
 directory of the llvm tree, I configured with:

 > myllvm : root of llvm tree
 > myllldb : tools/lldb in llvm tree
 > mybuild : build directory outside the trees

 > cd ${mybuild}
 > ${myllvm}/configure --enable-cxx11 --enable-optimized
CC=/opt/local/bin/gcc CXX=/opt/local/bin/g++

 and build with

 > make DEBUG_SYMBOLS=0 CC=/opt/local/bin/gcc CXX=/opt/local/bin/g++

 The used compiler is MacPorts' gcc-4.7 / g++-4.7

 LLVM compiles fine, Clang required me manually create
 "${mybuild}/include/clang/Config" and then symlink the
 "${mybuild}/include/llvm/Config/config.h into it.

 Clang compiled fine afterwards.

 Compiling LLDB now fails with:

 The checkout is from Jan 28th, revision 200341.

 How can I fix the problem, i.e. which exception specification is the
 right one?


 Best regards
