You may need to checkout from sourceforge CVS, the tar ball is not that
recent.

You may need to force your compiler to be gcc (clang or llvm)
I don't have the latter so I don't know whether they pass or not.
You see the logic of setting the compiler flags in
EASDIF_SDIF/SDIF/cmModules/SET_COMPILER_FLAGS.cmake
here
...
IF (GCCVERSIONMAJ EQUAL 4)
ADD_BT_COMPILER_FLAGS(RELEASE -finline-limit=5000 --param
large-function-insns=5000 --param large-function-growth=500 --param
inline-unit-growth=100)
So only gcc will trigger the problem
As far as I remember i did not have this machinery when I published the
last tar ball.
Please find attached a minimal example project (source tt.cc and
CMakeLists.txt) that trigger the problem.

Hmmm. I've downloaded the source from SourceForge, but do not
reproduce the problem here simply by running cmake to
configure/generate. You must be setting the flags explicitly somehow?
(By hand, or with a script?)
Can you tell me exactly how to reproduce the problem so that I can
verify the fix works?
The ExtractFlags method was modified in this commit to remove
conflicting -g flags when multiple -g flags occur...
http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=cb22afc0
It's relatively recent and first appeared in 2.8.6 -- I want to make
sure that whatever fix goes in now also honors the intent of that
commit, which fixed http://public.kitware.com/Bug/view.php?id=12377

Wow. Nice, quick work.
Thanks for the patch. I'll get it applied and pushed to our 'next'
branch so this can get into the next release...

It is the SDIF/EASDIF_SDIF project that is on sourceforge.
http://sourceforge.net/projects/sdif/files/Easdif/
> I've not heard of anything like this...
Thanks for the feedback. So I took the cmake sources and compiled in
debug mode to see what is the problem. In my opinion there is a bug in
cmGlobalXCodeGenerator::CreateBuildSettings
in function ExtractFlag(const char* flag, std::string& flags)
In my case I loop endlessly in
std::string gflag = this->ExtractFlag("-g", flags);
while I have these flags
-DGCC_HAS_VISIBILITY -fvisibility=hidden -fstrict-aliasing
-maccumulate-outgoing-args -DNDEBUG -DNDEBUG -funroll-loops -Wall
-Wno-switch -Wno-unused-function -finline-limit=5000 --param
large-function-insns=5000 --param large-function-growth=500 --param
inline-unit-growth=100 -fPIC
You see the -g is not there but something is found here
inline-unit-growth=100 -fPIC
and as the function is implemented
it does not handle this case correctly.
I suggest the following fix for the ExtractfFlag function
that ensures that a flag that is found will never be refound even
if it is nor removed (see FIX section below). The fix works for me.
std::string cmGlobalXCodeGenerator::ExtractFlag(const char* flag,
std::string& flags)
{
std::string retFlag;
std::string::size_type pos = flags.rfind(flag);
bool saved = false;
while(pos != flags.npos)
{
if(pos == 0 || flags[pos-1]==' ')
{
while(pos < flags.size() && flags[pos] != ' ')
{
if(!saved)
{
retFlag += flags[pos];
}
flags[pos] = ' ';
pos++;
}
}
saved = true;
// FIX IS HERE
// original version
// pos = flags.rfind(flag);
// corrected version
if(pos)
pos = flags.rfind(flag, pos-1);
else
pos = flags.npos;
// END OF FIX
}
return retFlag;
}
Cheers

What project are you running through CMake? Is it available for us to try to reproduce here? I've not heard of anything like this... Can you use Activity Monitor to inspect the process and grab a sample showing a call stack of what's happening when it's "hung"? Does CMake have any child processes that run during the configure of this project?
