Menuet Lib C fails to compile on Ubuntu 9.10

Wed Nov 18, 2009 6:40 am

I cant seem to get the Lib C for MenuetOS from here to compile on Ubuntu 9.10
Here is the output from GNOME Terminal

Your output seems to be not full. When I compiled libc by DJGPP the compile log was longer. Try to delete that file "/menuetlibc/src/libc/ansi/stdio/doprnt.o" and recompile libc if after that ar will not swear to doprnt.o and probably will on another *.o file then there was some files precompiled in the archieve and you would delete all such files and recompile libc.

I dont have doprnt.o but I have doprnt.c

I used XFCE Terminal this time and itgave me full output.

In the full log I've found 40 errors. I sugest maybe not very good but quick and simple solution for some errors.

1.)

Code: Select all

doprnt.c:820: error: static declaration of ‘isspeciall’ follows non-static declaration
doprnt.c:479: note: previous implicit declaration of ‘isspeciall’ was here

For an unknown to me reason __GO32__ preprocessor constant wasn't defined (by your compiler?). So try to comment lines 66 and 68 in doprnt.c like this:

Code: Select all

//#ifdef __GO32__
static int isspeciall(long double d, char *bufp);
//#endif

2.)

Code: Select all

ctime.c:97: error: static declaration of ‘tzsetwall’ follows non-static declaration
/home/cooldude2k/Documents/LinDev/menuetlibc/include/time.h:90: note: previous declaration of ‘tzsetwall’ was here

Comment static keyword on line 97 in ctime.c file like this:

Code: Select all

/*static*/ void		tzsetwall(void);

3.)

Code: Select all

bcmp.c: In function ‘bcmp’:
bcmp.c:17: error: lvalue required as increment operand
bcmp.c:17: error: lvalue required as increment operand

Your compiler don't like constructions like this:

Code: Select all

    if (*((const char *)ptr1++) != *((const char *)ptr2++))
      return length;

Try to change them to smth like this:

Code: Select all

 
if (*((const char *)ptr1) != *((const char *)ptr2))
      return length;
ptr1++;
ptr2++;

4.)

Code: Select all

swab.c:17: error: lvalue required as increment operand

Code: Select all

#define	STEP	temp = *((const char *)from++),*((char *)to++) = *((const char *)from++),*((char *)to++) = temp

I don't understand exactly what does this code do. So I can't correctly change it. Maybe smbd else could help you on this, or you can solve it yourself.
Good luck!

After doing the changes you said it compiled successfully.

Thanks very much for all your help.

I also want to thank to all. Now I understand some nuances. But I have yet another question. Does exist libc for KOS that supports console.obj for printf and 70 sys.func. for fprintf?

There is no special libc library that supports console.obj for printf function, but you can write a wrapper on con_printf and call it printf_ for example or better import it using such name. As far as I know diamond's libc use 70th function for all file operations. There is special theme for libc here: viewtopic.php?f=9&t=480
