I been playing around with openwatcom and made a script to build ngircd
its abit out of scope but i have managed to get this far and really could help with some pointers.
its based off stable 27 release of the daemon

this is my build script
build.txt

this is the error i do not understand.

Are you building this for ELKS? Or are you just using OpenWatcom to build for DOS? I am pretty familiar with the OWC settings required for ELKS but not familiar with the options in general.

For ELKS, please take a look at the ewcc and ewlink scripts in elks/tools/bin. I have spent a lot of time on them and we use the owcc wrapper for ELKS building rather than calling WCL directly. The general idea was to be able to say ewcc file.c file2.c file3.c, then ewlink file.obj file2.obj file3.obj and have it all work. The many many different options for WCL and OWCC have been consolidate into the the ewcc and ewlink scripts. (Of course, what would be nice would be to write a script 'ewcc' that was a true 'cc-like' wrapper around files and invoked the compiler and linker appropriately for file type but I haven't had time to complete that yet).

When building for ELKS, it is fairly important that you do NOT include any WATCOM/h directory in the include search path. This happens to be where your current compilation is dying. It is picking up <strings.h> from OWC rather than from ELKS libc/include.

Your build script looks quite nice and fairly fancy. I don't have to debug that script or look at the many options for WCL, but will try to help you get the daemon compiled for ELKS.

In summary, it looks like your problem is that the compile is including a WATCOM .h file, which is not supported by ELKS. The mess of OWC .h files is not something I want to get into. Thus, the important WATCOM .h files that we DO work with have been copied to libc/include/watcom/*.h. If/when your program uses a non-approved .h file, we can deal with getting it copied over, but that is not (yet) what is happening here. So remove the -IWATCOM/h from your build and/or look at how it is handled in ewcc.

[EDIT: I just happened to notice that ewcc does not yet have the WATCOM/h removed, so you should have the following instead:]

ELKSLIBCINCLUDE=$TOPDIR/libc/include
ELKSINCLUDE1=$TOPDIR/include
ELKSINCLUDE2=$TOPDIR/elks/include
#WATCINCLUDE=$WATCOM/h <--- comment this line out

source $TOPDIR/libc/watcom.model

    -Os                             \
    -std=c99                        \
    -Wc,-fpi87                      \
    -Wc,-zev                        \
    -Wc,-zls                        \
    -Wc,-x                          \
    -fnostdlib                      \
    -Wall -Wextra                   \
    -Wc,-wcd=303                    \
    -I$ELKSLIBCINCLUDE              \
    -I$ELKSINCLUDE1                 \
    -I$ELKSINCLUDE2                 \
    -I$WATCINCLUDE                  \ <--- delete this line
    "

You should be able to use the above information in order to get your script to work and get better results. Please let me know how you are doing on it, thanks!

ah yes things are making much more sense now, i removed watcom from my PATH.

I seem to be hitting this error
error.txt

[ghaerr]

Ok. Geez, my instructions as well as the current ewcc are still messed up (fix coming).

Now, you also need to add in a third include, which is where we have copied some watcom header files: libc/include/watcom.

Thus, the proper list should be:

ELKSLIBCINCLUDE=$TOPDIR/libc/include
ELKSINCLUDE1=$TOPDIR/libc/include/watcom
ELKSINCLUDE2=$TOPDIR/elks/include

That is, for your build, you need to include $TOPDIR/libc/include/watcom also.

[ghaerr]

Actually, the proper order should not matter, but could:

ELKSLIBCINCLUDE=$TOPDIR/libc/include
ELKSINCLUDE1=$TOPDIR/elks/include
ELKSINCLUDE2=$TOPDIR/libc/include/watcom

error.txt

[ghaerr]

/usr/bin/watcom/h/strings.h(55): Error! E1009: Expecting ')' but found '('

Look at the error: you're including WATCOM's strings.h. Bad, change it. Reread my above comments, we're not talking about OWC PATH but include paths. I don't know how WCL works, as I mentioned, I only use owcc.

[parabyte]

sorry its very late here, so may call it a night, i posted a incorrect error file,

this is the correct error file
error.txt

[ghaerr]

Look through the error messages, they are somewhat explanatory, then get some sleep!

src/ngircd/client.c(28): Error! E1055: Unable to open 'strings.h'

Check if #include "strings.h" or <strings.h>, needs to be the latter.

src/ngircd/client.c(94): Error! E1031: Name 'h_name' not found in struct/union hostent

This one is more tricky - I have no idea: there is no struct hosting on ELKS, so you'll have to dig down more to see where or what it is.

This could be something to do with Watcom TCP. The big problem you are likely to have, from what I was reading when you first posted this, is that this program uses Watcom TCP. I don't think it is compatible with UNIX/BSD sockets, which is what ELKS uses. So the TCP access portions may need rewriting.

src/ngircd/client.c(79): Error! E1011: Symbol 'PACKAGE' has not been declared

I have no idea what this is, there is no PACKAGE in ELKS C library. You can grep the Watcom clib sources for it, but that usually gets complicated very fast.

[ghaerr]

how do i disable watcoms tcp?

You can't, although I'm not sure what the compiler errors are other than that. What I'm talking about is the source code to NGIRCD is written for Watcom TCP. It may have to be recoded for UNIX/ELKS sockets. I haven't looked at the source code so I can't tell. You're welcome to chase down some of the source lines that the errors show and post them, or post a link so I can click it, as I am short on time myself.

[parabyte]

im actually stuck, wondered if maybe you could give me some pointers or insight,
`/home/arduino/source/elks/libc/include/errno.h(7): Error! E1009: Expecting ';' but found 'extern'

code that is throwing the error.
conf.txt

[ghaerr]

No problem, but this undoubtedly has to do with your Makefile etc having been setup improperly with regards to the required include file order, and lots of other little things. This is why I wrote the ewcc script. It is too complicated to explain all that is required, but it is all in the ewcc script. Try running ewcc ngircd.c or whatever the filename you're trying to compile is.

That should work better. After that, you can study what ewcc does versus what you are doing in your Makefile, which hopefully is the issue. You can use ewcc for each of your source files, then ewlink *.obj to link, and its all done for you. I can't debug the many options OWC has, which is why I prepared a script to use for ELKS.

code that is throwing the error.

I can't compile that without removing all the local .h file includes, because I don't have them. I did comment them all out and ran ewcc and didn't get the error your getting though, which is good.

I hope that helps?

[parabyte]

is this what you had in mind?
build(2).txt

[ghaerr]

Yes, nice. But does it work? I don't think the ewcc script is smart enough to accept "-o file" or -c, etc. It was written quickly with the intent to compile a single .c file quickly, using the OWC toolchain and having the includes/defines/settings set compatibly for ELKS.

What I had in mind was for you to try manually compiling one or each of the .c files, rather than through a complex script, so that you/we could more easily understand the errors that might be produced from compatible compilation of the program you're porting using the OWC compiler. Then at least we know we have the compiler switches and include file ordering correct, and we can see what other errors there are. After that, if you want to make a more complex build, then moving to a complex make script will be easier.

I say all this because we haven't been able to determine whether it is your setup or the .c files themselves that are most contributing to making this port hard. Also, I doubt that ewcc will work other than manually, unless it is extended to be more like a cc replacement.

In summary, what happens when you just run "ewcc ngircd.c"? That is the file you had the problems with shown above, right?

[parabyte]

progress is coming along slowly, I have not abandoned this project, just running into some watcom specific obscurities

[ghaerr]

No problem, take your time! I plan on updating ewcc and ewlink to be more useful also, when I have a bit more time.

[parabyte]

any idea whats going on with this

/home/arduino/source/elks/libc/include/sys/time.h(8): Error! E1009: Expecting ';' but found 'struct'

many thanks in advance.

[ghaerr]

It sounds like possibly another issue of the include files not being setup properly - I would have to see the source file it came from and how it is being compiled. Looking at sys/time.h, it looks pretty normal. Are you compiling using ecc or a different method?
I never heard back from you regarding whether trying ecc rather than your Makefile helped or not. Thanks!

[parabyte]

ecc was the answer to my problems, I have been exclusively using that as my tool of choice, Turns out my issue was that watcom was parsing some code intended for a gnu compiler in one of its header files, specifically porttab.h, im slowly getting into the mindset with working with watcom. less hand holding unlike other friendlier modern compilers.
