Switching to clang 2.8

Simone Pellegrini
  Dear all,
I am working on a project where we use clang internally for parsing and
rewriting capabilities.

I decided to give clang 2.8 a try and replaced the old installation with
the RC2. I had to make some changes in the code but not big deal, the
main problem I cannot solve now is the linking.

When I build llvm I use the flag 'clang-only' to build the part I am
interested in.
I built llvm using the following 2 commands:

./configure --prefix=.. --enable-shared --enable-asserts
make REQUIRES_RTTI=1 clang-only && make install clang-only

In order to feed the clang library to my project I have a cmake file
where I specify one by one the libraries which has to be linked.
I noticed that libCIndex.a so I updated my cmake file by removing any
reference to it. Basically this is the list of libraries (from the cmake
file):

find_library(clang_CompilerDriver_LIB NAMES CompilerDriver     PATHS
${LLVM_HOME}/lib)
find_library(clang_Basic_LIB           NAMES clangBasic         PATHS
${LLVM_HOME}/lib)
find_library(clang_Sema_LIB          NAMES clangSema         PATHS
${LLVM_HOME}/lib)
find_library(clang_CIndex_LIB        NAMES CIndex             PATHS
${LLVM_HOME}/lib)
find_library(clang_Driver_LIB         NAMES clangDriver     PATHS
${LLVM_HOME}/lib)
find_library(clang_AST_LIB             NAMES clangAST         PATHS
${LLVM_HOME}/lib)
find_library(clang_Rewrite_LIB       NAMES clangRewrite     PATHS
${LLVM_HOME}/lib)
find_library(clang_Analysis_LIB      NAMES clangAnalysis     PATHS
${LLVM_HOME}/lib)
find_library(clang_Lex_LIB             NAMES clangLex         PATHS
${LLVM_HOME}/lib)
find_library(clang_Frontend_LIB     NAMES clangFrontend     PATHS
${LLVM_HOME}/lib)
find_library(clang_Parse_LIB          NAMES clangParse         PATHS
${LLVM_HOME}/lib)
find_library(clang_Index_LIB          NAMES clangIndex         PATHS
${LLVM_HOME}/lib)

set(clang_LIBs  ${clang_CompilerDriver_LIB} ${clang_CIndex_LIB}
${clang_Sema_LIB} ${clang_Driver_LIB} ${clang_AST_LIB} ${clang_Rewrite_LIB}
                 ${clang_Analysis_LIB} ${clang_Lex_LIB}
${clang_Frontend_LIB} ${clang_Parse_LIB} ${clang_Basic_LIB}
${clang_Index_LIB})


When I try to compile my project with the new clang I get a linking
error, it looks like some definitions are missing or perhaps they have
been moved in another library:

Actually I solved the problem myself.

The solution was the order in which the libraries are listed. The
following order solved the link errors:
set(clang_LIBs    ${clang_Clang_LIB}
                            ${clang_Index_LIB}
                            ${clang_Checker_LIB}
                            ${clang_FrontendTool_LIB}
                            ${clang_Frontend_LIB}
                            ${clang_Driver_LIB}
                            ${clang_Basic_LIB}
                            ${clang_Lex_LIB}
                            ${clang_Parse_LIB}
                            ${clang_Sema_LIB}
                            ${clang_AST_LIB}
                            ${clang_Rewrite_LIB}
                            ${clang_Serialization_LIB}
                            ${clang_Analysis_LIB}
                            ${clang_Basic_LIB}
