Unofficial FreeBASIC 1.04.0 OS X release

[venom]

Hi,
I just built FreeBASIC 1.04.0 for OS X and thought that some of you might be interested in this. You can download it here (i don't know how long this link will stay valid, it would be cool if this could be uploaded to sourceforge where the other releases reside). Please note that for building and running graphical applications you will need XQuartz, and you probably also need to add "-asm att" when compiling with fbc.

I can't guarantee that it will run on your system (OS X support isn't very mature yet), but it did on mine and I was able to run graphical examples with it.

Spend me a mac and I will test it a night long ;-)

What a day in history of FreeBASIC
a MAC port and JavaScript HTML5 webGL backend on one day :-)

first of all thank you for the Mac release of FB
I installed FB by running the install script, installed ok
fbc -version

FreeBASIC Compiler - Version 1.04.0 (10-12-2015), built for darwin-x86_64 (64bit)
Copyright (C) 2004-2015 The FreeBASIC development team.

but I had to hunt down crt1.o which was nowhere on my system, also had a problem with the type FILE which I found defined in inc\crt\dos\stdio.bi if I remember right, after that things started to work.
but it took several seconds for the fb graphics screen to show up

but get some warnings

fbc -w all -asm att hello.bas
clang: warning: optimization flag '-frounding-math' is not supported
clang: warning: argument unused during compilation: '-frounding-math'

got geany working, for some reason it refused to open a basic file but after making a new file and saving it, it works.
of course I had to adjust the compiler command, other than the afore mentioned warnings everything seems to work
except console programs don't respond the the numeric pad.

Well, actually the OS X work is already a few weeks old and was merged together with my patches for NetBSD, FreeBSD and Solaris (which should be usable also, but I was too lazy to assemble a build yet ;) ).
But that emscripten port really is pretty amazing ;)

but it took several seconds for the fb graphics screen to show up

Yep, that's one of the disadvantages of using XQuartz: It has to start a full X.org server before anything can show up. But once it's running windows should appear faster.
I have been playing around with Cocoa a bit, but I'm still unsure whether I should try writing a Cocoa-backend or simply doing a SDL2-backend, which would probably be a good idea for other platforms. And, of course, finding the time is another problem ;)

but get some warnings

Yeah, the OS X port still lacks some polish.

thanks for checking in and answering our concerns. :)
I would love to know the details of the process you went thorough to get this fb port working, give us the details in failures as well as the details in the success.
hope you keep up this project. :)

hello D.J.Peters
your C64 emulator compiles and works ok
the reason that programs using graphics take some seconds to appear on the screen is that they use X11
if X11 is not running, then X11 is first launched, but afterwards the program appearing on screen is instantaneous

hello venom
could you tell me the steps required to compile fb in os x?
considering that I will be using fb that you compiled
I have the latest os on my mac, but when running make I get the following error

src/compiler/obj/ast-gosub.c:1:0: error: -masm=intel not supported in this configuration

when I try compiling the rtlib I get the following error

make rtlib
CC src/rtlib/obj/darwin-x86_64/thread_call.o
src/rtlib/thread_call.c:33:10: fatal error: 'ffi.h' file not found
#include <ffi.h>
^
1 error generated.
make: *** [src/rtlib/obj/darwin-x86_64/thread_call.o] Error 1

booting into os x Yosemite and executing make rtlib works, but fail to compile fb

I probably need to re-install command line tools

Maybe you know that FBC and its components use (L)GPL licenses? Personally I would consider it a NO-GO to publish a binary package on Sourceforge without the according source-code (if differing from the 1.04 one) and/or Makefiles/Tools (if needed). (but of course that's something dkl/counting_pine/... have to decide)

[srvaldez]

I think my system is missing some required libraries, but what I don't understand is the "error: -masm=intel not supported in this configuration"
the only thing I can think of other than the obvious missing lib is that the makefile may need tweaking which I have no idea how to do

Yes.

The code is the exact same as all other 1.04.0 releases. All my patches to make this work were merged by dkl before the release.

That's the reason why "-asm att" is needed. By default, fbc uses the Intel syntax for assembly, which isn't supported on the OS X toolchain. You should be able to build everything with this (should be correct, but I can't try it right now):

make FBFLAGS="-asm att" ENABLE_XQUARTZ=1 all

when I try compiling the rtlib I get the following error

make rtlib
CC src/rtlib/obj/darwin-x86_64/thread_call.o
src/rtlib/thread_call.c:33:10: fatal error: 'ffi.h' file not found

1 error generated.
make: *** [src/rtlib/obj/darwin-x86_64/thread_call.o] Error 1

You need to have libffi installed to build the rtlib.

thank you venom :)
btw, why the nickname venom = poison?

hello venom and dkl
I finally Managed to compile fb on my mac, there were some warnings but it's working, except now I get a bunch
of ld warnings like following

ld: warning: option -s is obsolete and being ignored
ld: warning: -macosx_version_min not specified, assuming 10.10
ld: warning: object file (/usr/local/bin/../lib/freebasic/darwin-x86_64/fbrt0.o) was built for newer OSX version (10.11) than being linked (10.10)
..... more warnings
Compilation finished successfully.

any advice on how to fix this?

They're not critical, so you can basically ignore them until I find the time for the next round of patches ;)
