Summary0013331: AIX linker chokes on spaces in rpath
DescriptionI was looking into why so many tests were failing on my AIX 5.3 dashboard:

    http://open.cdash.org/viewTest.php?onlyfailed&buildid=2378283 [^]

It seems to come down to the linker's -blibpath option. Compare the below two invocations---the only difference is "My Tests" in the first one, and "My_Tests" in the second:

host:~/Dashboards/My Tests/CMake-build/Tests/COnly> env OBJECT_MODE=32 /usr/bin/gcc -mminimal-toc -O0 CMakeFiles/COnly.dir/conly.c.o CMakeFiles/COnly.dir/foo.c.o -o COnly libtestc1.a libtestc2.so -Wl,-blibpath:"/home/cport/Dashboards/My Tests/CMake-build/Tests/COnly:/usr/lib:/lib"
ld: 0706-014 The -b Tests/CMake-build/Tests/COnly option is not recognized.
collect2: ld returned 255 exit status

host:~/Dashboards/My Tests/CMake-build/Tests/COnly> env OBJECT_MODE=32 /usr/bin/gcc -mminimal-toc -O0 CMakeFiles/COnly.dir/conly.c.o CMakeFiles/COnly.dir/foo.c.o -o COnly libtestc1.a libtestc2.so -Wl,-blibpath:"/home/cport/Dashboards/My_Tests/CMake-build/Tests/COnly:/usr/lib:/lib"
(no error)

This should probably be checked when CMake first looks at the compiler/linker, as a fail-fast behavior would be helpful here.

(I checked that this isn't a problem with gcc or even collect2 mishandling the option; I get the same error even if I pass -blibpath:"..." directly to ld.)

Moving to backlog awaiting a specific proposal and/or patch to add fail-fast behavior. Compilers have many features of which rpath is only one. We can't check everything up front. Some project might not even use such features and would needlessly be prevented from working.
