beebasm - building

[JohnCoachWalsh]

Hi,

I've just tried to clone/build beebasm, from github, and I get a compile error:

Code: Select all

Compiling ... commands.cpp
commands.cpp: In member function ‘void LineParser::HandlePutFileCommon(bool)’:
commands.cpp:1757:51: error: ‘streampos’ is not a member of ‘std::ifstream’ {aka ‘std::basic_ifstream<char>’}

make[1]: *** [Makefile.inc:227: objects/commands.o] Error 1
make: *** [Makefile.inc:183: objs] Error 2

I tried 3 branches:

Code: Select all

git clone https://github.com/stardot/beebasm/
git clone https://github.com/stardot/beebasm/ proposed-updates
git clone https://github.com/cpu6502/beebasm/ bug-streampos

and I got the same compile error in all 3.

I'm on Linux (Fedora 35, or Debian 10 or 11).

Please can anyone tell me what branch I need, to compile OK?

Thanks,
John.

Hmm, works for me...

Also worked on my CentOS 7 install.

Are you using the native gcc compiler, or an alternative? Do you have CFLAGS or similar set?

[tricky]

Last time I went to build it, it failed because my compiler was newer and didn't allow what the old one did. I can't remember if I used an older compiler or fixed the couple of bits it didn't like. Since I'm on Windows and only use Vs,I think I'm in a very small minority.

OK, so I created a fresh install of Debian 11. Nice fresh out of the box.

And I got a build error.

The issue I saw there:

Code: Select all

commands.cpp:1757:26: warning: std::ios_base::streampos is deprecated: use 'std::streampos' instead

I was able to get it to compile on Debian 11 by removing "-Werror" from the Makefile so that this just was presented as a warning and didn't break the build.

[SteveF]

Just FWIW, I think this has come up before - see this issue which links to this issue.

Does anyone feel comfortable coming up with a patch that will probably work on "everything"?

Edit: It might actually be fixed on the proposed-updates branch, I'm not sure. It really would be good to get another "official" release out, I guess.

Thanks @sweh.

I tried removing the -Werror, but it made no difference for my build.

So I've changed the line of c++ code in commands.cpp:

Code: Select all

					//ifstream::streampos p = inputFile.tellg();
					std::streampos p = inputFile.tellg();

That now lets the code build (I put the -Werror back in).

I don't know c++, so if anyone can comment on if this line change is valid ???

And now I'll be starting to use beedasm for the first time, so I'll assume my code change is working, until I hear otherwise.

Thanks all.
John.

FYI: I just tried to run beebasm, and I get:

Code: Select all

./beebasm: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.34' not found (required by ./beebasm)

Somehow your runtime libraries are older than your build time libraries. (That can happen if you build on one machine and try to run on another. For work purposes, I used to build on the oldest machines.)

Can you run an update on your OS?

In my case, on Ubuntu 18.04, I see

Code: Select all

Hmm, https://tracker.debian.org/pkg/glibc says that Debian only comes with glibc 2.31, but your binary is looking for 2.34.

Are you using a custom build of gcc that's pointing to custom library directories? That'd also explain why you're getting different compile errors to what I saw on a fresh Debian 11.

However you might also see a similar error if you compiled on Debian 11 and tried to run it on Debian 10 (which has glibc 2.28 and glibcxx 3.4.25).

You are corect.

I do have 2 laptops, with different distros on: Debian and Fedora.

So I had compiled on Fedora, and then tried it later on the Debian one.

Thanks.

I hope this post is relavend for my question: How to get BeebAsm built for Windows?

The Beebasm readme.md asks me to download MinGW from (http://www.mingw.org) which is a broken link. Is this now MinGW-64.org ? If so, what do I download from the download page.

The readme.md also asks to install the basic subset of cygwin.org. I have downloaded the setup86_64.exe but no option for a basic setup. Maybe base (38) is the thing, but I dont want to assume that is the same thing.

Many thanks.

[roganjosh]

I just did this today. My browser wasn't keen on that mingw site at all (security warnings). Instead I downloaded it from https://sourceforge.net/projects/mingw/files/

The base (38) is what you need from the cygwin package section. You'll also need to install 'make' .

Don't forget to add the cygwin and MinGW 'bin' directories to your user or system 'Path' environment variable and, at least, close and reopen any terminal windows afterwards (or, to be ultra-sure, reboot).

EDIT: Corrected incorrect MinGW URL.
