[Solved] Xfont error in DOS

[Gablea]

Hi everyone

I hope someone can help

I am getting a error when I run the following command 'fbc -g -exx npos.bas' I get the following

ld: npos.o: in function 'SIGNONPASSWORD_CHANGE_1': c:\npos\NPOS.BAS:321: undefined reference to 'XFONT::INTERFACE::BACKCOLOUR__set__ (unsigned long)'

I am running a PURE DOS machine (FreeDOS 1.3) but in Windows the project complies with no issues

I have re created the xfont library in DOS

can someone tell me what it mean and what I need to do to resolve this issue.

Thanks

Sounds like you've declared the function 'XFONT::INTERFACE::BACKCOLOUR__set__ (unsigned long)' and also use it in 'SIGNONPASSWORD_CHANGE_1', but there's no implementation for it. Or at least the linker can't find the implementation.

There could be multiple reasons for this. For example, you could be missing a library or object file while linking. Or the mentioned function is really missing. Or declaration and implementation signatures do not match. .. just to mention a few possibilities.

The same code will compile with no issues at all in Windows and Linux. I had this problem before but I always sorted it by re making the Library with the current version of my fbc and this is Version 1.10.0 (2023-05-14), Built for dos (32bit) (Standalone)

I have done fbc -lib xfont.bas (and it creates a libxfont.a that i have moved to my c:\fbc\dos\lib folder)

Does the xfont library need something that windows / Linux provides?

As I am running a 64 bit version of Windows I can not compile directly on DOS on my PC (I have a Pure FreeDOS development PC that is on my network and that is what I am using to compile)

hello Gablea
why not make an amalgamation of the code and skip making a library?
I tried it and there's no problem

I made the new version of the library as the one on the xfont website was complied with 1.07 and it does not work

I read on here as well that it needed re making with 1.10

How would I make a amalgamation (I've not got any clue as what you mean)

He means just include the files from xfont as part of your source code, rather than linking to it as a library. Then you compile it all together into your binary. No library needed. Might solve some of your problems, or maybe make the problem more plain and easier to solve.

Note that if you're building a proprietary binary you intend to sell, the license of the xfont code may not permit compiling it statically into your own project code. I'm not exactly sure what the xfont library is, or where the source code comes from.

@caseih and others, xfont website is http://xaviorsoft.freebasic.net/ but has not been active for quite some time, also verybadidea has a github copy here https://github.com/verybadidea/XFont-Lib

Thank you srvaldez what ever you did worked and my program fully complies now on pure DOS

Thank-you once again

[srvaldez]

glad it worked

Although I made a copy on github with some some fixes, I don't knot much about the library. But I was wondering if BACKCOLOUR should be BACKCOLOR (without the U).
