who succed to compile freetype 2.X ?
I didn't succed cause of the apparently wellknown problem of _WinMain@16. I read all the messages on different lists, the faq (but don't want to add a main() ) the -Wl,-u, ... has not effect. I need the freetype as a pre requisite to compile the gd. 2.0 to get imagefontheight in php4 But if someone has a previous version of gd and other image lib as dll, i will be happy if he can give me the url link. -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Bug reporting: http://cygwin.com/bugs.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
Re: gcc problem?
I didn't program in C for a long time but as far as I remember,
scanf read 1 string using white space as separator.
to enter aaa bbb ccc
you need scanf(%s %s %s, ...) or gets
use gets
or scanf(%s, ..)
followed by
while('\n'!=getchar());
but you loose the extra typed words
hope this helps.

Hello,
Ever since I installed a newer cygwin, I've encountered problems which I
didn't encounter before. First, there was the
ls -lproblem which has not yet been resolved (and which is threaded as ls
problem in this list.). Just today, i discovered something wrong while
using gcc. I compiled the snippet below and it's supposed to prompt me for
input twice. However, I only get prompted once. (Using the visual c++
compiler, the borland 5.5 compiler gives the correct results)
The reverse is true for the example below: ie you were encountering
problems before, but not realising it.
My gcc version is 2.95.3-5.
Cygwin version is The cygwin1.dll version I am using is
1.3.15-cygwin-1-3-15-1.
---begin snippet-
#include stdio.h
int main()
{
int n;
char string[80];
for ( n=0 ; n2 ; n++ )
{
printf( Enter some words: );
scanf( %s, string);
printf( The first word you entered is : %s\n, string );
fflush ( stdin );
^^^hint: while('\n'!=getchar());
}
return 0;
}
You can't flush(stdin). Nothing wrong with Cygwin here, simply the other
compilers implementing stuff that isn't part of the language. The FAQ
for comp.lang.c or alt.comp.lang.learn.c-c++ will no doubt give you
ample insight.

SYMPTOMS:
when I compile a source defining a function and calling it,
the program coredumps.
I already compiled on this machine using 2.95.
This happens since the update gcc 3.2
I fully reinstall cygwin (today: 11/20/2002 at 14h:00( PARIS/FRANCE)
packages from programming.ccp14.uk), the same always happens.
What I compiled, rox file manager for instance, is always functionnal.

looking for compiled lib
I'm looking for the gd and freetype lib as dll. I didn't find them via setup nor following link about ported software. Has anybody more information about these (compiled ) lib ?

GCC: what is wrong with function
I got problem compiling some software and see that some of them core dumps when
calling functions deefined in their code.
Here is a very simple test program.
It runs perfectly as we can expect under AIX.
#include stdio.h
int p(char *s);
int main(int argc, char *argv[]) {
int ind = 0 ;
int r = 0 ;
for ( ind = 0 ; ind argc ; ind++ ) {
printf(%d:%s\n,ind,argv[ind]) ;
}
printf(-\n ) ;
for ( ind = 0 ; ind argc ; ind++ ) {
char *ptr=argv[ind] ;
printf(%d %d\n,ptr, argv[ind]) ;
printf(%d %d %s\n,ind,sizeof(ptr),ptr) ;
printf(%d %d %s\n,ind,sizeof(argv[0]),ptr) ;
printf(%d %d %s\n,ind,sizeof(int),ptr) ;
r = p(argv[ind]) ;
printf(%d %d %s\n,r,ind,ptr) ;
}
return(0) ;
}
int p(char *s){
printf(dans p:%d %s\n,s,s) ;
return(2);
}

and the result is :

Sometimes it coredumps, but this time we can see :
1) the code in p function isn't executed
2) the following printf after the call show a return value (r) incoherent.
I got gcc using setup, it seems to be a prerelease. But I don't belive gcc is
concerned, I surely miss something?
I have no time to investigate.
Some explanation.
