If path to the build directory contains spaces (e.g. meson setup 'a b') then our mocks don't work. The problem is in glibc where not just a colon but also a space character is a delimiter for LD_PRELOAD [1]. Hence, a test using mock tries to preload something like libvirt.git/a b/libsomethingmock.so which is interpreted by glibc as two separate strings: "libvirt.git/a", "b/libsomethingmock.so". One trick to get around this is to set LD_PRELOAD to just the shared object file (without path) and let glibc find the mock in paths specified in LD_LIBRARY_PATH (where only a colon or a semicolon are valid separators [1]). This can be seen in action by running say: LD_DEBUG=libs ./virpcitest 1: https://man7.org/linux/man-pages/man8/ld.so.8.html Signed-off-by: Michal Privoznik <mprivozn@redhat.com> Reviewed-by: Ján Tomko <jtomko@redhat.com>
