As of release time, GCC 5.3 is the newest compiler verified to work to build the GNU C Library. + For multi-arch support it is recommended to use a GCC which has + been built with support for GNU indirect functions. This ensures + that correct debugging information is generated for functions + selected by IFUNC resolvers. This support can either be enabled by + configuring GCC with '--enable-gnu-indirect-function', or by + enabling it by default by setting 'default_gnu_indirect_function' + variable for a particular architecture in the GCC source file + 'gcc/config.gcc'. + You can use whatever compiler you like to compile programs that use the GNU C Library. |
