<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This is driving me nuts, and it’s almost certainly
something dumb. One of my CMake users lost a hard drive and had to reimage.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Now she’s installed CMake 2.8 and it LOOKS like
it’s all OK, but any attempt to do a CMake hangs because the attempt to
compile CMakeCCompilerId.c winds up passing a bunch of flags and then
“-o CMakeCCompilerId.c” – that is, the -o flag, TWO
spaces, and then CMakeCCompilerId.c. So there’s no output file
specification; the input filespec becomes the output, and the compiler dutifully
waits for input from stdin.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Now, I think I’ve seen this before, but I’m
damned if I can remember what causes it. As far as I can tell, the compiler
call is generated within cmake.exe, which kinda makes it hard to debug.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any ideas? Thanks in advance…<o:p></o:p></p>
