"Error! E738: option requires a number" when using compiler option -et

[Binarus]

Hi all,

I just wanted to profile a DOS application and tried to compile using the compiler option -et. This produced the error which is mentioned in the subject. According to the manual (cguide.pdf), this option does not take additional parameters.

These are the flags I'm currently using for compiling:

CFLAGS = -5 -bt=DOS -d3 -e20 -ef -ei -er -fpi87 -fp5 -mh -od -wx -zdf -zff -zgf -zt256 -zu

This works, but as soon as I add -et, the error occurs. I am using OpenWatcom 1.9, running the compiler within Windows, but cross compiling for DOS.

Any ideas?

Thank you very much,

Binarus

You don't get much info as what compiler you use, what is real commnd line
etc.
I only deduce what happen.
It looks like you use wpp compiler (16-bit).
Unfortunately it doesn't support -et option, for it you must use wpp386
compiler (32-bit). cmdl parser recognize -et option as -e option with number
which is not entered.
Parser generates a little confusing diagnostics.

Jiri,

thank you very much for your answer which was very helpful.

It seems you are right. A complete command line is (example):

c:\watcom\binnt\wpp.exe -5 -bt=DOS -d3 -e20 -ef -ei -er -fpi87 -fp5 -mh -od -wx -zdf -zff -zgf -zt256 -zu -fo=test.obj test.cpp

I just did not come to the idea that there are differences in the command line options the different compilers understand. Therefore, I did not mention exactly what compiler I was using.

Since I am doing development using a virtual machine which runs XP Pro, I think I can use wpp386. I will now try to find out which compiler supports which targets - I need a compiler which supports the DOS target, and I hope that wpp386 does this.

Cheers

wcc is 16-bit C compiler
wpp is 16-bit C++ compiler
wcc386 is 32-bit C compiler
wpp386 is 32-bit C++ compiler

All can compile for DOS with -bt=dos
