Hi there,
I tracked down the problem. Turns out I was using the GNAT gcc, so
that wasn't the problem as you all suggested. (But thank you for the
help.) It turns out that GNAT bind doesn't like read-only libraries.
Don't ask me why, I don't know enough about Ada to say, but in trying to
figure out the problem I ran across this document:
http://ip-sol.jp/download/spartan2/h8devel_src/gcc-3.4.0/gcc/ada/bcheck.adb
search for "is obsolete and read-only"
so this tells me that since my gnat install was installed in my system
not in my home directory, it wasn't going to work.
To get around this, you can pass gnatbind the "-t" option. I added it to
ghdl/vhdl/Makefile.in as follows:
gnatbind -Lgrt_ -o run-bind.adb -n ghdl_main.ali ----->>>> gnatbind -t
-Lgrt_ -o run-bind.adb -n ghdl_main.ali
The compile then succeeds.
As one might suspect, this workaround does cause the ghdl code to be
recompiled each time you try to make anything.
I am building on an x86_64 target under Gentoo Linux.
