Jakub, is there any additional info I need to provide for this? Thanks. Worked around in cpp-4.7.0-0.11.fc17 in rawhide, will see if the lto plugin dependency for -E/-S/-c compilation can't be avoided in the driver instead. *** Bug 799594 has been marked as a duplicate of this bug. *** |
Description of problem: I want to use cpp to do some text substitution. I don't want gcc installed (public facing server). If cpp is used when the gcc package is not installed, cpp barfs with an LTO shared lib error message: This is on an f16 machine with gcc installed: [mjd@xiaomao ~]$ cat /etc/redhat-release Fedora release 16 (Verne) [mjd@xiaomao]$ rpm -q cpp gcc cpp-4.6.2-1.fc16.x86_64 gcc-4.6.2-1.fc16.x86_64 [mjd@xiaomao ~]$ rpm -V cpp [mjd@xiaomao ~]$ echo | cpp # 1 "<stdin>" # 1 "<built-in>" # 1 "<command-line>" # 1 "<stdin>" This is on a machine that does not have gcc installed: [mjd@example ~]$ cat /etc/redhat-release Fedora release 15 (Lovelock) [mjd@example]$ rpm -q cpp gcc cpp-4.6.1-9.fc15.i686 package gcc is not installed [mjd@example ~]$ rpm -V cpp [mjd@example ~]$ echo | cpp # 1 "<stdin>" # 1 "<built-in>" # 1 "<command-line>" # 1 "<stdin>" cpp: fatal error: -fuse-linker-plugin, but liblto_plugin.so not found compilation terminated. [mjd@example ~]$ logout (The return code was 4, which breaks makefiles and stuff) This problem occurs in both F15 and F16. How reproducible: Every time, just run "echo | cpp" Actual results: See above (f15 machine) Expected results: See above (f16 machine) Additional info: This bug has already been fixed in debian: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=639531 Their fix was to move LTO from gcc to cpp.
