[Resolved] Using OpenWatcom compiler in C::B

[Eric75000]

Hello everybody !

First of all, excuse me for my bad english, I'm a little frenchy  :lol:

I'm using C::B 1.0rc2 with OpenWatcom 1.7 compiler (last version)

I'm trying to create a user template on C::B who allows me to use a 32bits program in a DOS extender like DOS4GW. (Yes, I know it's a old method, but it's to learn... :wink: )
I start with the "Console Application" initial template (Files/New Project...) and modify it to use Open Watcom compiler. (Right click on "Console application" in my workspace, Targets, Target's build options, Selected compiler, OpenWatcom (W32) Compiler)

But when i try a Ctrl+F9, it's not the good version of Open Watcom compiler who starts (wcc386.exe instead of wcl386.exe)

Where can I modify this parameters ? (Obtain in Selected compiler something like "OpenWatcom (DOS - 32 bits) Compiler" as OpenWatcom can normaly do)

Can anyone help me, please ?
Thanks in advance !

Bests Regards,
Eric.

RC2 is pretty old. Please download a latest nightly from the following link.

http://forums.codeblocks.org/index.php/board,20.0.html

I'm afraid that even if you change the compiler executable to wcl386.exe it may not work well with RC2. Lately the support of newer OpenWatcom compilers has been enhanced in recent nightlies.

BTW, please note that the Console Wizard will create the Project for Win32 executables (console). In case you want to create a DOS executable, you've to change the appropriate command line option (-bt=dos) in Project > Build options.

[Eric75000]

Thanks Biplab for your answer !

I'll install the latest nightly this evening like you recommand... (I stayed at RC2 version because in France, in some forums like this one, they do not recommand to use nightly builds... so like I'm a beginner...:mrgreen:)

BTW, please note that the Console Wizard will create the Project for Win32 executables (console). In case you want to create a DOS executable, you've to change the appropriate command line option (-bt=dos) in Project > Build options.

I'm not sure that the comman line option (-bt=dos) works because in the prog is inserted some ASM instructions (witch use DOS interruptions)
And the prog to work properly must use DOS4GW, and if you use another compiler executable instead of wcl386.exe, it will compile but not work...

I'll try it this evening and tell you...

C U soon,
Eric

I just gave you an example. I wanted to say that in case you want to develop programs for DOS, you'll need to change certain parameters.

I hope you'll get a better experience with C::B nightlies as opposed to other forums say.

Hi !

=> Now I'm using C::B Nightly build SVN4491 : what the difference compared to RC2 !!!! 
So I've found where I can transmit the "-l=dos4g" command line (Thanks Biplab) to the compiler...
But the prog still doesn't work !

Where can I config more verbose build logs in C::B please ? (only 5 lines in SVN4491 instead of many many lines in RC2)

Basically, everything.

Where can I config more verbose build logs in C::B please ? (only 5 lines in SVN4491 instead of many many lines in RC2)

Compiler settings, rightmost tab, select "full command line".

[Eric75000]

Thanks Thomas for your answer !

Build logs are a little more verbose but not enough :? : although none compiler flag is set, when I build my prog, I can see in build log "wcl386.exe -q -c..." and after "wlink.exe option quiet..."

=> This is why I can't see all of the logs : -q flag = operate quietly for compiler, and option quiet = quiet (!) for the linker.

Somebody knows please where can I unset this flag ? I search in Settings/Compiler and debugger and in my project properties but I've found nothing !

Don't worry about that difference. That's hard-coded. It won't affect your project.

Unfortunately the command line options of wlink.exe is not same as of other tools, such as wcl386.exe. So option quiet may seem odd to you but it is the option which wlink.exe uses.

[Eric75000]

Hi !

Sorry for my late answer, I was in holidays...

It won't affect your project.

I know, I know !!! :wink:

That's hard-coded.

Argh ! It's too bad that you can't set or unset by yourself this flag ! I know this flag ins't very very important, but I was accustomed at the logs of RC2 version :oops:

So, I have another problem : when I want to compile my prog in OpenWatcom with inline command, I must type in a DOS window :

Code

wcl386 /l=dos4g my_starfield.c

I would like to do the same in C::B, so in the build options of my projet, I set the flag "link for the specified OS (define TARGET_OS in custom variables) [-l=[TARGET_OS])" and click "Add" button in the "Custom variables" tabs and type "$(TARGET_OS)" for the key, and "dos4g" for the value...
But, when I build my prog, (F11) I can see in the logs : wcl386.exe -q -c -l= 

The compiler take well the flag but not the custom variable $(TARGET_OS)
Where I made a mistake

(I hope you understand my very very bad english :oops:)

This is a bug. Actually not all linker options are mapped to their equivalent wlink.exe command. It needs to be fixed.

[Biplab]

I've fixed the bug (Not expanding the Custom variables). It's in revision 4505.

Regarding changing the option quiet you can do this. Go to Settings > Compiler & debugger > Other settings. Now click on the Advanced button. There you can change the linker command by editing that line and removing option quiet from that.

If you find any other bugs, please feel free to report it.

[Eric75000]

Hello everybody !

Biplab : many many thanks to take your precious time to help a little frenchy like me by changing C::B code to allow modifying logs flags in Openwatcom compiler & linker : it's so cool
=> I'm now in 4515 revision and, for this, it works like I want !!!! :mrgreen: :mrgreen: :mrgreen:

But for the "custom variables", I must do a mistake (but I don't know where) because it doesn't work instead of you've fixed the bug !
It's like exactly the same that previously :

in the build options of my projet, I set the flag "link for the specified OS (define TARGET_OS in custom variables) [-l=[TARGET_OS])" and click "Add" button in the "Custom variables" tabs and type "$(TARGET_OS)" for the key, and "dos4g" for the value...
But, when I build my prog, (F11) I can see in the logs : wcl386.exe -q -c -l=

 :cry: :cry: :cry:

 :cry: :cry: :cry:

I guess you're making some mistakes. This is what happens in my PC. I've used -l=$(TARGET_OS) compiler options and a custom variable TARGET_OS with value nt_win for the project.

Really, you could do that for me ?

=> Here are all my [little] projet... (it's to learn how using 13h video mode like old PC 80's demo)

Thanks in advance for your precious help !!!

:cry: No answer :cry:

=> Nobody is interrested more by my prog

Biplab ? Sorry but, can U help me please ? :oops:

[Biplab]

It works as expected.

In your attached project file there is no instance of the required Custom variable for this operation.

I'm attaching the modified project.

Hi Biplab (and all) !

And thanks to you for your answer !!!
I was near the truth : in fact, I wrote $(TARGET_OS) instead of TARGET_OS because it's written like this in the "Custom variables" windows... :oops: sorry !!!

So now, effectively, it works as expected... for the flags, but not for my prog ! :cry: :cry: :cry:

I'm searching why I have all this errors (while it works correctly when I compile it manually) : may be I'll need your help once again...

 :wink:
 

[Eric75000]

Hi !

It's me again... :mrgreen:

So, instead of trying to search where I made mistakes, I still need your help : I don't understand why, when I compile my prog in Openwatcom directly by command line it works perfectly with no error, and when I use C::B to do the same (same prog, same flag to compile, etc) I always have lots of errors, even whith latest version of C::B (SVN4564) :

After many searchs, I've found in a french forum an old post (2003) who explain that this kind of problem appears in Openwatcom when path is uncorrectly notified... But my path is:

Code

PATH=C:\WATCOM\BINNT;C:\WATCOM\BINW

So, where is my error

[Eric75000]

I'm not sure, but I think it's not an error... but a bug !

In the logs, we can see that the LIBP flag for the linker correctly notices the good library path :

Code

wlink.exe system dos4g debug watcom all  LIBP  C:\watcom\lib386;C:\watcom\lib386\nt file obj\Debug\main.obj name bin\Debug\my_starfield.exe

And the "clib3r.lib" file (that apparently makes problem) exists in C:\WATCOM\lib386\nt !

So, I don't think that this time I made a mistake...
Someone can confirm my thought ?

[Eric75000]

=> There's no one who can help me

May be Biplab... again ?

[Biplab]

Remove C:\watcom\lib386\nt from library search path. Then add C:\WATCOM\lib386\dos to the library search path. That should solve the problem.
