53 | <para >The kernel's <filename class="directory">asm-ppc</filename> and |
---|
54 | <filename class="directory">asm-ppc64</filename> headers were merged into |
---|
55 | <filename class="directory">asm-powerpc</filename> during 2.6.15. Glibc for |
---|
56 | powerpc installs a version of <filename>procfs.h</filename> which looks for |
---|
57 | the __PPC64_ELF_H symbol to determine if it is running on powerpc64. That |
---|
58 | symbol disappeared in the merge, its replacement does not indicate if the |
---|
59 | machine is running as 64 bit. The absence of the original symbol causes |
---|
60 | the 32-bit definitions to be used, which leads to compilation failure early |
---|
61 | in 64-bit glibc when an incompatible kernel definition is included. The |
---|
62 | following sed will correct this, we need to repeat it every time we install |
---|
63 | either size of glibc.</para> |
