LCC does not supports nested functions
May you have any solution how to fix it?

Use GCC to build or provide patches to use a different construct both compilers understand. -- You are receiving this mail because: You are on the CC list for the bug.

https://sourceware.org/bugzilla/show_bug.cgi?id=26708 --- Comment #2 from Mark Wielaard --- Note that there should be a configure test to check that your compiler has all capabilities to build elfutils: # We use -std=gnu99 but have explicit checks for some language constructs # and GNU extensions since some compilers claim GNU99 support, but don't # really support all language extensions. In particular we need # Mixed Declarations and Code # https://gcc.gnu.org/onlinedocs/gcc/Mixed-Declarations.html # Nested Functions # https://gcc.gnu.org/onlinedocs/gcc/Nested-Functions.html # Arrays of Variable Length # https://gcc.gnu.org/onlinedocs/gcc/Variable-Length.html Normally if your compiler doesn't support those language constructs the "Checking for for gcc with GNU99 support..." test should fail. If it doesn't in your case we might have to tighten up the configure check. -- You are receiving this mail because: You are on the CC list for the bug.
