c++.idde - DOS project woe

I just received my digital mars cd.  Thanks.
When I compile using the command line tools with -Ic:\devp\dm\stlport\stlport it
works.

#include <iostream>

int main()
{
std::cout << "Howdy." << std::endl;
return 0;
}

The idde gives me these errors when I use c:\devp\dm\stlport\stlport on the
project dialog's include line in window 4 of the project | new dialogs building

What am I or am I not doing to be able to build with the idde?

std:: designation works fine so the problem isn't grave. I just wondered. http://www.obsoletedigital.com "To play is to pray" --Rev. Lance Swagger

Same problem in DigMars C++ 7.51, Win32 environment, newly arrived on CD. A solution would be appreciated. Like Steve, I also found that it was necessary to include the path to dm/stlport/stlport and also the same+ /stl in order to recognize <iostream>, dirent.h, etc. That would appear to be an omission in C++ as delivered. A related puzzle: whereas the syntax errors reported by Steve listed 'fgetwc', 'fgetws', 'fputwc', and 'fputws' as the offending "unidentified identifiers", the compiler is telling me instead that 'fgetws', 'fputws', 'getwchar' and 'getwc' can't be found, while it doesn't complain about 'fgetwc' and 'fputwc'. In any case, these identifiers are in fact not found in wchar.h, which is included in <cwchar>, which is evidently invoked by something else up the chain to <iostream>. - Ralph Bertonaschi

I will say that using <iostream.h> without including the stlport Include and the std:: designation works fine so the problem isn't grave. I just wondered. http://www.obsoletedigital.com "To play is to pray" --Rev. Lance Swagger

Same problem in DigMars C++ 7.51, Win32 environment, newly arrived on CD. A solution would be appreciated.

Not really. STLport is open source software, as to be bundled separately from DM proper. Plus, there're a program that likely depend on the older header files. You're always free to change/modify/update/hack/maim/slaughter the sc.ini file in any way you see fit. Add the \dm\stlport\stlport directory to the INCLUDE setting.
 A related puzzle: whereas the syntax errors reported by Steve listed 'fgetwc',
 'fgetws', 'fputwc', and 'fputws' as the offending "unidentified identifiers",
 the compiler is telling me instead that 'fgetws', 'fputws', 'getwchar' and
 'getwc' can't be found, while it doesn't complain about 'fgetwc' and 'fputwc'.
 In any case, these identifiers are in fact not found in wchar.h, which is
 included in <cwchar>, which is evidently invoked by something else up the chain
 to <iostream>.

I'm not entirely sure which version of STLport Walter is shipping with DM these days. I haven't gotten around to porting STLport 5 yet, but an updated version 4.6.2 for DMC can be had from http://mordred.cs.ucla.edu/STLport_DMC/ Hope that helps.

Use instead the older <iostream.h> when working with DOS.

STL in general is not supported in 16 bit memory models.

Thanks - I'm in the IDDE and Win32 environment, and anyway it's the same problem w/ <iostream.h>; maybe it's <string> that does it. I guess I should have put my query in the STLport newsgroup, which I've just found and read. "Drake" in Apr '04 suggested this: #define _STLP_NO_NATIVE_WIDE_FUNCTIONS = 1 which I did, in the program I'm using to evaluate DMC compared some other compilers. It then got past the "unidentified identifiers" 'getwchar" etc. So far so good, having compiled just that file via the IDDE editor, but when I try project "build", those identifiers are still missing and the build fails. I took a look at the STLport download information at the UCLA site that Scott suggested and ... well, having seen the difficulties reported by some evidently very competent individuals in the STLport newsgroup thread, it would seem to be a poor use of time to go ahead and download the thing, figure out what all of the flags mean, and hope get it right, all on the if-come that it just might work under 4.6.2, when the real objective (for this non-Computer Science person) is to get an application written and running. Hopefully another DMC release will solve this problem, which is evidently not mine alone. I remain amazed at the prompt replies to me and at the hard work, intelligence and attention to detail that are evident from the dialogues in the news forum, on the part of individuals (like yourselves) who must be extraordinarily busy. - RB

STLPort wasn't designed to work for 16 bit builds nor was it tested for 16 bit builds. There are two iostream.h's: \dm\include\iostream.h \dm\stlport\stlport\iostream.h Use the first one, which means do not allow \dm\stlport\stlport to be on your INCLUDE path. Check the INCLUDE environment variable, and any sc.ini you're using, and the default sc.ini in \dm\bin to make sure the stlport one isn't being included. While DMC++ fully supports exception handling and templates for 16 bit code, the full featured bloat of STL is too big for 16 bit programming, where saving every byte is a necessary fact of life.

programming book on C++ and am kind of jazzed that I came up with a solution that seems to fit what the problem was. You more experienced people are amazing. Slowly but surely.
