I have successfully written a doubly linked list with generics so I think I am starting to have a feel for the language. However, my binaries have always seemed a bit large compared to my C/C++ ones for similar data structures. I looked in the Wikibook FAQ about it and it instructed me to look at the various compiler options. In the course of this, I discovered GNAT's project files. I looked at few examples and wrote my own. My problem is that it always runs just the GCC without calling gnatbind or gnatlink as it does if I just call gnatlink. In any case, I figure that I could call gnatbind and gnatlink manually from there. When I do that, gnatlink fails with this error (it also happens when I use gnat gps IDE and its project files so this is happening often): ~/adastuff/testhello$ gnat make -Phello.gpr gcc-4.2 -c -O3 -gnatn -funroll-loops -fPIC -fprofile-arcs -gnat05 -I- -gnatA ~/adastuff/testhello/hello.adb ~/adastuff/testhello$ gnatbind -x hello.ali ~/adastuff/testhello$ gnatlink hello.ali b~hello.o: In function `global constructors keyed to 0_ada_main_E': b~hello.adb:(.text+0x2f2): undefined reference to `__gcov_init' b~hello.o:(.data.rel+0x48): undefined reference to `__gcov_merge_add' ./hello.o: In function `global constructors keyed to 0__ada_hello': hello.adb:(.text+0x82): undefined reference to `__gcov_init' ./hello.o:(.data.rel+0x48): undefined reference to `__gcov_merge_add' collect2: ld returned 1 exit status gnatlink: cannot call /usr/bin/gcc-4.2 Might anyone have any ideas? Have I missed something in the call to gnatlink? I can post code if that will help. Thanks in Advance!, Chris
