I want to use a generic data structures library ( http://libds.sourceforge.net/ ) but when compiling, the following is displayed by GCC 3.2 on cygwin:
Code:
avltree.o(.text+0x6d7):avltree.c: undefined reference to `_impure_ptr'
avltree.o(.text+0x779):avltree.c: undefined reference to `_impure_ptr'
avltree.o(.text+0x93a):avltree.c: undefined reference to `_impure_ptr'
avltree.o(.text+0x9de):avltree.c: undefined reference to `_impure_ptr'
avltree.o(.text+0xa06):avltree.c: undefined reference to `_impure_ptr'
avltree.o(.text+0xb02):avltree.c: more undefined references to `_impure_ptr' fol
low
make[2]: [libds.a] Error 1 (ignored)
What is this _impure_ptr? Do I have to worry about it?
Thank you for your help.
