Open Watcom problems\questions

[madnut.ua]

I try to use Open Watcom with C::B and have some problems with it.

1. I can't specify path of the libs for the linker. wcl386.exe uses wlink directive for it. It's look like:

Code

wcl386.exe -"LIBPath <path> ..."

where <path> - it is my path for libs. In C::B I can't specify that directive in Settings->Compiler...->Other->Advanced Options->Others, cause path must be in quotes. If I write some like -"LIBPath", than command will be like: wcl386.exe -"LIBPath"c:\bla\bla... - that is incorrect.
Another way. If I write directly in linker field in commands tab -"LIBPath $libdirs", that will be also incorrect, cause all paths in that directive must delimited by ";", not by space as in C::B.
How can I resolve this problem?

2. I can't link resource file to exe. wcl386.exe writes that it unknown object file. I try to use wrc.exe with -zm option for Microsoft .res compatible file, but it also not work. So, what to do?

3. How can I specify PCH file for the project? I try to use -fh option with specify "watcom.pch" file, but while compiling, this file was recreated for every cpp file in the project.

Who can help me with my problems?

imho, some errors in c::b code:
compilerOW.cpp

Code

52: m_Programs.MAKE             = wxT("mingw32-make.exe"); // need "wmake.exe"?
...
55: m_Switches.libDirs          = wxT("-L"); // it's not watcom option
...
341: m_RegExes.Add(RegExStruct(_("Note"), cltError, wxT("([A-Za-z0-9_:/\\.-]+)\\(([0-9]+)\\): Note! (.+)"), 3, 1, 2)); // must be cltInfo instead of cltError

p.s. sorry for "nice" English

project (or you can even put on compiler level) : Directories tab (or Linker tab maybe for other settins)

project (or you can even put on compiler level) : Directories tab (or Linker tab maybe for other settins)

and what? of course, I write my paths here, but full command line looks like:

Code

wcl386.exe  -LC:\wxWidgets\lib\wat_dll -LC:\wxWidgets\lib -L..\..\lib -LC:\watcom\lib

It's incorrect, cause "-L" - is key for gcc, not for watcom.

[madnut.ua]

Also I try to create new project with project wizard. wxWidgets application with watcom compiler. But I get error in script. see attach

It's incorrect, cause "-L" - is key for gcc, not for watcom.

I am trying to verify that  "-L" works or does NOT work, since I have NOT used Watcom C before it might take awhile for me to reach an answer. The documentation implies that it will NOT work.

The testing is starting to confirm that "-L" does NOT work as a way to set patch to look for libraries.

[Biplab]

Official wxWidgets wizard does not support OpenWatcom. So no settings are added for that. The error you are getting in the script is due to some uninitialised variables. Nothing to worry on that.

PCH file should be created first using some header or cpp file. Otherwise you can keep all the header includes in all the cpp file consistent. That means every time the compiler encounters a cpp file PCH mode, it would see that the include headers are similar, and it would not recreate the PCH file.

I'm not sure how OpenWatcom creates PCH file. But you can set some command to create PCH file through wx/wxprec.h and then try to use the generated PCH file.

OpenWatcom is in my to TODO list for wxWidgets project wizard. But I need to know it more before I can start working on it.

I know what killerbot was talking about now;

He meant that instead of listing the linker directories under "Directories" -> "Linker" to use instead "Linker" -> "Linker other options". This seems to help get past the first errors I was getting, but I am getting other errors because I have no idea on how to use Watcom with wxWidgets.

I added this to "Linker other options" and it seemed to work.
-"libpath C:\wx\inno\wxWidgets\lib\wat_lib"

[killerbot]

yes, that's what I was suggesting.

@madnut.ua :
1) Can you have more the none LIBPath <path> ... ?
2) Could you give an example where you want to add 2 paths "PathA" and "PathB", preferably each as a separate setting, please give such an example of the full command line.
I will adjust this evening then.

You can already manually change it (look in default.conf in your user-dir\codeblocks : the compiler sets)

[killerbot]

If the name of a library file appearing in a "LIBRARY" directive or the the name of an object
file appearing in a "LIBFILE" directive contains a path specification, only the specified path
will be searched.
Note that
libpath path1
libpath path2
is equivalent to the following.
libpath path2;path1

[killerbot]

@madnut.ua

I have the changes ready to commit, but you will have to manually adjust your defaul.conf anyway, unless you delete it [otherwise the changes in the CB soures won't have any effect].

Change this in your default.conf to try out, to see if it works (note nothing to do with wx wizard !!) :
- look for <ow>
- then the subtag <Make> and change from :

Code

				<MAKE>
					<str>
						<![CDATA[mingw32-make.exe]]>
					</str>
				</MAKE>

to

Code

				<MAKE>
					<str>
						<![CDATA[wmake.exe]]>
					</str>
				</MAKE>

then look for the subtag(s) : <switches> <LIBS>
and change from :

Code

					<LIBS>
						<str>
							<![CDATA[-L]]>
						</str>
					</LIBS>

to

Code

					<LIBS>
						<str>
							<![CDATA[-LIBpath]]>
						</str>
					</LIBS>

and finally look for <regex><re001> and change from

Code

						<TYPE int="2" />

to

Code

						<TYPE int="0" />

that last one will change it to cltNormal, we don't have cltInfo, so not sure if this will have the desired effect
Please provide a simple line of code that will trigger a *note*. According to the dropdown box the "Info" should map to cltNormal.

Please provide us with your feedback, so I can commit this evening the fixed code.

EDIT : Make sure all cb instances are closed when you make this changes !

[madnut.ua]

Thanks all for help!

@madnut.ua

Please provide us with your feedback, so I can commit this evening the fixed code.

I already change it before.

But -libpath not work, as I write before.

If the name of a library file appearing in a "LIBRARY" directive or the the name of an object
file appearing in a "LIBFILE" directive contains a path specification, only the specified path
will be searched.
Note that
libpath path1
libpath path2
is equivalent to the following.
libpath path2;path1

It's docs for wlink.exe. For wcl386.exe directive must be in quotes: -"libpath path1" or -"libpath path1;path2"

wcl386.exe translate this line to wlink for parsing. so it must be in quotes. Else I get error, cause wcl386.exe parse it as "-l=<os> link for the specified OS".

But if I write libs path in Linker tab like: -"libpath C:\watcom\lib",
c::b translate it to command line like: wcl386.exe "-"libpath C:\watcom\lib"" ...
so it doesn't work(

[killerbot]

what if we specify as program for "Linker for dynamic libs" (no idea what will happen for exe's) : wlink.exe
(For static libs wa also specify wlib.exe) instead of wcl386.exe

Maybe we need an extra program : Linker for executables.

[EDIT] For MSVC the link.exe specified for dll's is also used (I guess) for exe's.
[EDIT2] : I think it's better to directly use the wlink instead of the wcl386, those i do all programs that then call other's , pff ;-)

[severach]

C::B is a long way off from proper Watcom support. I now build my projects in the Watcom IDE to find out what the proper command lines are and transfer them over to C::B.
