Hi, There are some problems with the different version of SuSE ! I have compiled the following c program (the simplest one): void main() { printf("toto\n"); } on different release of Suse, and after when I tried to execute it on different version of SuSE, I have obtained very strange results. (Note : the compilation was simply made with the command "gcc" without any arguments) compile on 5.3 : run on 5.3 -> OK 6.3 -> OK 7.0 -> "command not found" (!!!) 7.2 -> "command not found" compile on 6.3 : run on 5.3 -> "command not found" 6.3 -> OK 7.0 -> OK 7.2 -> "BUG IN DYNAMIC LINKER ld.so: dynamic-link.h:62: elf_get_dynamic_info: Assertion `! "bad dynamic tag"'" compile on 7.0 : run on 5.3 -> "command not found" 6.3 -> OK 7.0 -> OK 7.2 -> "BUG IN DYNAMIC LINKER...." compile on 7.2 : run on 5.3 -> "command not found" 6.3 -> OK 7.0 -> OK 7.2 -> OK Could somebody explain what happen ? Thanks a lot.
