Ok, when should I turn off executable stack? execstack says, that libSDL requires exec stack: $ execstack -q /usr/lib/libSDL-1.2.so.0.7.1 X /usr/lib/libSDL-1.2.so.0.7.1 The output of obdum is this: $ objdump -p /usr/lib/libSDL-1.2.so.0.7.1 | grep -i stack STACK off 0x00000000 vaddr 0x00000000 paddr 0x00000000 align 2**2 What to do? http://people.redhat.com/drepper/nonselsec.pdf The above URL has all the information you need. For an assembler file you need to add -Wa,--execstack to the compiler command-line. execstack for libSDL prevents ekiga from starting. You may want to steal^Wborrow some patches from Gentoo ;-) http://catmur.co.uk/gentoo/trees/gentopia/media-libs/libsdl/files/ (I'm not shure whether this mirror is up-to-date) http://catmur.co.uk/gentoo/trees/gentopia/media-libs/libsdl/files/libsdl-1.2.9-no-exec-stack.patch Fixed in rawhide in rpm SDL-1.2.9-5. |
