The make install do not work...

Hm, problems generating the shared object files... Lets fix this on another day. For now you can use the static binaries. Btw: xbbc.static is the bytecode compiler. It should also work.

xbbc.static example.bas
should produce a file called b.b

run this with

xbasic.static b.b

btw: you can also rename the binaries and remove the .static extension.

[Markus Hoffmann]

If you encounter segfaults with some examples this most likely come from the 64 bit architecture. Any example using PEEK, POKE, VARPTR() can not work because the variables are only 32 bit integers and the do not convert to 64 bit memory adresses. This problem has nothing to to with the OS-X but with adaption to 64 bit operating systems in general. There is also a paragraph on this topic in the manual. I have no solution to this so far.
btw: many example programs use pointers to memory... but when you write your owns you can avoid them. I myself still use a 32bit ubuntu os.

UPDATE 2017-04: this should be fixed now!

I understand, Thank you. And what about the sound? What it can be done?

[Markus Hoffmann]

Sound was not compiled in because libasound is not present on your system, at least the configure script has not found it. Maybe you can install it (called alsa sound lib), then do a configure and make static again. this would enable the SOUND and WAVE commands (playsound.bas). If you just want to play soundfiles as samples you can use an external command like mpg123 or ogg123 from inside the basic programs. Like it is done in ballerburg.bas.

For today is a lot of things. Thank you for the support. I hope the "betatesting" helped!

I'm still playing/testing it. I fear the libasound does not exist on Mac, so could be this basic will be silent.
There is a strange thing in graphic mode: if I use CLEARW, the draws are erased from X11 window, but the first 5% (more or less) top window is not erased. I do not know if this could be fixed.

[Markus Hoffmann]

Hm, this sounds strange. can you post a screenshot?

[Anonymous]

This is the result of this code:

for i = 1 to 100
gprint i
showpage
next i
clearw
showpage

[Markus Hoffmann]

OOps, there was a bug in CLEARW. I have fixed it...

[Anonymous]

Thank you. I started a clone, and all is fine. CLEANW is... cleaning now ;)

I'm missing something with this code?

while true

    a$=inkey$
    print a$

wend

I do not understand if there is a problem or I do not understand something in basic inkey syntax.
If I run, nothing happens.

[Markus Hoffmann]

Maybe you need to press a key to see something. Btw: Al though it should work, INKEY$ should not be used like this, because it would take all the processor capacities for the endless loop. Maybe it prints so fast that any output whould have been immediately scrolled away. Use some pause in the loop, e.g. PAUSE 0.1.
if you need to wait for key input consider to use KEYEVENT (when using the graphics window) or INP(-2) when using the console output. INKEY$ also works on the console only.

[Anonymous]

The keyevent is working in X11 window. The inkey$ is not working in terminal.

Hi.

I use a Mac, with GCC5 from MacPorts. This setup use to work very well, including Python 3.x (I compiled locally evert version since 3.0 to early test my programs). However, besides the .configure sucessfullt detecs the GCC toolchain, while compiling I get:

ld: unknown option: -Bsymbolic-functions
collect2: error: ld returned 1 exit status
make: *** [libx11basic.so.1.25] Error 1

What sugests the LLVM toolchain is being used instead! (the LLVM's ld doesn't understand what is symbolic-funcions). Since the Python guys managed to make this work somehow, I'm giving a peek on their configure.in file in the hope to find a solution.

make static in the mean time still works.

[Markus Hoffmann]

Hm, have you tried to remove this option in the Makefile? Maybe it simply works without it....

[David Hall]

I am struggling to install on MAC

Have MacPorts gcc5 and also X11 Quartz also run latest xcode 8.3.2 with command line installed

when I run ./configure

attached is config.log [config.log]

[David Hall]

I have had a little more success by trying the command
./configure CC="cc"

however when I trie to make I get some fatal errors

[Markus Hoffmann]

Ok, this means that at least the configure script is satisfied. You try before, it complained about a wrong version of gcc (should be >=4).
Which version of the sourcecode have you used? I recommend the latest version from gitlab, branch master. Then lets look at the errors from make

[David Hall]

My GCC Version
Davids-MacBook-Pro-2:src davidhall$ gcc --version
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1

Target: x86_64-apple-darwin16.6.0
Thread model: posix
InstalledDir: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin

OK, I downloaded the gitlab master branch

Davids-MacBook-Pro-2:src davidhall$ ./configure

Davids-MacBook-Pro-2:src davidhall$

[Markus Hoffmann]

Hm, it looks like that something is wrong with the detection of the gcc version.
As a quick workaround: open configure in an editor and look for the line 3667

copt="-O3"
v=`gcc -v 2>&1|grep version|sed 's/^.*\([0-9]\.[0-9]\.[0-9]\).*/\1/g'`
if test `echo $v|sed 's/\.//g'` -lt 245; then
    echo "You have only version $v, please install a newer version of gcc!"
    exit 1
else
    echo "Using gcc version $v"
fi

remove the "exit 1" statement, save it and try again.

[David Hall]

Markus thanks for taking the time to help me, i'm almost there I can compile static but not the full version

ld: unknown option: -Bsymbolic-functions
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [libx11basic.so.1.25] Error 1

[Markus Hoffmann]

Hm, Ok, maybe open Makefile and remove -Bsymbolic-functions from line 49 and try again. But remember: I have no idea, how shared libraries on a MAC are organized. It might be different from what I know on linux systems. So better not do a make install without ensuring, that the files and the places where they are installed to are correct. Someone else may help here.

The other thing is, that you still have no X.org support in even the statatic versions of X11-Basic. This should be fixed first.

The version you have compiled has no graphics, no sound, no usb support, no big integer support, no fft support, no blueooth support. But you should at least get the big integers and graphics running.
