Hello all, I had problem compiling OLSR-0.4.8 under Fedora Core 4 (FC4) with gcc 4.0, I got the error as follow: ... make[1]: *** No rule to make target `/usr/lib/gcc/i386-redhat- linux/3.4.4/include/stddef.h', needed by `olsrd_conf.o'. Stop. ... I used to compile and run OLSR under FC3 successfully. Thank you. Bing
