<div dir="ltr">Hi Tim,<div><br></div><div>I ran into the same issue today. I think what's happening is that you (and I) first did an in-tree autoconf build, then started an out-of-tree cmake build, and manually deleted all the autoconf-generated files that cmake complained about. However, ../llvm-git/tools/clang/lib/StaticAnalyzer/Checkers/Checkers.inc didn't get deleted (not sure why cmake didn't warn about that one), so the old autoconf-generated Checkers.inc got picked up by clang during the cmake build. The fix which worked for me was to run</div>

Hi,<br>
<br>
I had a couple of mysterious build problems on the svn trunk recently<br>
and I'm not smart enough to fix them but I thought I could at least<br>
mention them to someone else. I don't know if the problems are really<br>
bugs or just my poor reading of the build instructions.<br>
<br>
I was building with clang and clang++ 3.3 on Fedora 19 x86_64. I don't<br>
remember the revision at this point although it was Sunday 11th August<br>
and must have been on or before r161722.<br>
<br>
1. GNU Autotools build.<br>
Whatever I did, I couldn't get this to work. I tried building only<br>
the x86_64 platform and that caused a lot of failures from pieces of<br>
code that obviously expected the other platforms to be there. When I<br>
built with all the platforms I got almost everything to build but<br>
still had errors about the MBlaze platform (obviously llvm not clang)<br>
and then some much more mysterious problems which seemed to be related<br>
to undefined macros that were clang related. I forgot to save the<br>
output from this which is stupid and I'm not greatly eager to repeat<br>
the experience but I certainly will if asked. I don't know if<br>
autotools is supposed to be maintained but if so then it doesn't work<br>
for me.<br>
<br>
2. Cmake<br>
With cmake there was eventual success but I had to patch it because I<br>
reached something very hard to understand that related to namespaces.<br>
I don't want to submit a full patch because I don't really understand<br>
the problem and what I did could easily have been incorrect but I<br>
thought that the registration of checkers was not very uniform and<br>
seemed to be happening in the wrong namespaces. It might have been a<br>
clang3.3 bug in the way namespaces are handled - that is the only<br>
reason I can imagine for everyone else being able to build this and<br>
not me.<br>
<br>
The kind of error I got was:<br>
<br>
========<br>
[ 96%] Building CXX object<br>
tools/clang/lib/StaticAnalyzer/Checkers/CMakeFiles/clangStaticAnalyzerCheckers.dir/DebugCheckers.cpp.o<br>
/home/tim/build/llvm/tools/clang/lib/StaticAnalyzer/Checkers/DebugCheckers.cpp:200:12:<br>
error:<br>
out-of-line definition of 'registerExplodedGraphViewer' does not<br>
match any declaration in<br>
namespace 'clang::ento'<br>
void ento::registerExplodedGraphViewer(CheckerManager &mgr) {<br>
========<br>
<br>
e.g. in lib/StaticAnalyzer/Checkers/CheckSecuritySyntaxOnly.cpp I had<br>
to do this kind of thing to get past namespace errors<br>
<br>
#define REGISTER_CHECKER(name) \<br>
-void ento::register##name(CheckerManager &mgr) {\<br>
+void clang::ento::register##name(CheckerManager &mgr) {\<br>
mgr.registerChecker<SecuritySyntaxChecker>()->filter.check_##name = true;\<br>
}<br>
<br>
And then there were other complaints about other functions that<br>
weren't declared in the clang:ento namespace but changing them like<br>
this didn't work (in lib/StaticAnalyzer/Checkers/DebugCheckers.cpp):<br>
<br>
-void ento::registerExplodedGraphViewer(CheckerManager &mgr) {<br>
+void clang::ento::registerExplodedGraphViewer(CheckerManager &mgr) {<br>
mgr.registerChecker<ExplodedGraphViewer>();<br>
}<br>
<br>
only this worked:<br>
<br>
-void ento::registerExplodedGraphViewer(CheckerManager &mgr) {<br>
+namespace clang { namespace ento {<br>
+void registerExplodedGraphViewer(CheckerManager &mgr) {<br>
mgr.registerChecker<ExplodedGraphViewer>();<br>
}<br>
+}}<br>
<br>
<br>
The total list of modified files was:<br>
<br>
ndex: lib/Frontend/CMakeLists.txt (had to add LLVMBitReader for some reason)<br>
Index: lib/StaticAnalyzer/Checkers/CheckSecuritySyntaxOnly.cpp<br>
Index: lib/StaticAnalyzer/Checkers/DebugCheckers.cpp<br>
Index: lib/StaticAnalyzer/Checkers/MallocChecker.cpp<br>
Index: lib/StaticAnalyzer/Checkers/NonNullParamChecker.cpp<br>
<br>
I'm sorry this isn't more detailed or reasoned. Hope it's useful to someone.<br>
<br>
Regards,<br>
<br>
