Cross compiler for QDOS c68 on POSIX platforms

xtc68's Issues

compilation terminated

Trying to compile XTC68 on a Linux ubuntu 4.15.0-36-generic #3916.04.1-Ubuntu SMP Tue Sep 25 08:59:23 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux with gcc (Ubuntu 5.4.0-6ubuntu1~16.04.10) 5.4.0 20160609

Keep getting these errors. Seems like some files are missing....

install.sh freezes under Cygwin

This is just to inform you that install.sh freezes under Cygwin 32 bit under Windows 10 64-bit.
If I try to run it (without the sudo command), it justs freezes.
Nothing is copied from support (where I have unzipped the required files) and no folders are created in /usr/local.

It may be a non-issue, as I see the built-in Widows anti-malware process use a lot of CPU any time I run the script... Maybe it is just a Windows 10 problem... which I need to circumvent somehow.
Sorry, it this information is useless to you.

How to use install.sh? cp cannot star 'as68/as68'... error

I have downloaded the lastest version of xtc68, as well as the support (disk1) files (in support directory). I am using Lubuntob64 bit with a 32 bit dev env as suggested.

install.sh fails with multiple cannot stat errors (as68/as68, ..., ld/qld no such file...)

It does manage to just copy the support files to their target directories.

slb -L should not close files twice

slb, has since the beginning (1992), closed libfp twice; depending on your OS / libc the affects may range from:

• nothing; to
• corrupted heap and slb crashing, with no output.

This is now fixed by d1d1baa, which also added qdos-ar and qdos-ranlib helpers.

README.md dead link

Dilwyn Jones's homepage referenced from the README.md file has moved to

https://dilwyn.qlforum.co.uk

Substructures below this link have apparently been retained as from the original page.

The old link "dilwyn.me.uk" is dead as of now.

Where do I find the instructions on how to install the cross compiler?

Sorry. My problem is that I need to install the cross compiler.
The README.md file suggests to use copy the support files and run "install.sh". That is what I do.
I am trying to follow the instructions but I am doing something wrong.
Could you please point me to the installation procedure to get the compiler fully installed?
By installed I mean able to run qcc on the hello world example. The README.md seems to suggest only running install.sh does everything.
Do I need to run "make", configure?

A working installer is required

The old move.pl is somewhat useless.
This repo should not include runtime files that are available elsewhere.

Compiling Errors

I tried to compile XTC68, on Linux Mint 21.2 x64, which the compiler compiles okay, but there are errors in the tools: qls, qcp

Here is ninja output:

[buffer overflow] xtc68 fails to compile/link code that gcc (and others compiler) have no problem with

If I try to compile even a sub-set of my project
https://github.com/Fabrizio-Caruso/CROSS-CHASE
with make xtc68_test (shown below) I get

root@brizio-VirtualBox:/media/sf_Retro/CROSS-CHASE/src# make xtc68_test

[question/bug] How to build and use?

I have managed to build under Ubuntu 64 bit and a 32 bit environment.

I have done:
make all
sudo move.pl

Nothing is found in /usr/local/bin

If I try to run qcc I get an error about qcpp not being found.

What do I need to do to install the compiler?

Double defined Symbol Warning

xtc68 issues these warnings where it probably should not.

test.txt

Attached a test program, the compiled version of which works as it prints 2 3 when run so the symbols are not actually overwriting each other like the warning would indicate.

qcc -o test-c68 test.c
Double defined Symbol: _ONE
test-c68: dataspace 870 (366)
