Subject: [Simh] Cross-assemblers, cross-compilers: success! (so far)<br>

First of all, thanks for the replies to my post asking for a PDP-11 cross-assembler for linux/unix environments.<br>
<br>
I've been playing with some of the suggestions I got, and finally I have decided to try to build a GNU toolchain configured as cross-compiler. Although it has some issues (the most annoying is that the default script used by the linker has a syntax error!), it can be used and it works. I've also written a small program to convert from the a.out format generated by the "ld" linker to the "paper tape" format that the SIMH load command expects. <br>
<br>
To cut the story short, I've been able to write, compile, link and execute a small "hello world" program over a bare metal (simulated) PDP-11. I've written a blog post about that small acomplishment, where if you are interested you can see the steps I followed and you can find the small utility I've written.<br>
