I have a question .
Firstly:
I make a "C library".The "C library" source code is below:
http://www.uclinux.org/pub/uClinux/libraries/
uC-libc-310899.tar.gz.
I build a "libc.a" using "make " in cygwin.
secondly:
I do an example "a.c".below:
//a.c
#include <stdio.h>
void main()
{
printf("success!");
return ;
}
I want to use "printf" function in libc.a, not in libcygwin.a.
so I using a new libcygwin.a ,not original libcygwin.a.
ar r libcygwin.a _cygwin_crt0_common.o _cygwin_S_IEXEC.o cygwin_attach_dll.o cygwin_crt0.o dll_entry.o dll_main.o libcmain.o premain0.o premain1.o premain2.o premain3.o regcomp.o regerror.o regexec.o regfree.o
thirdly:
complied the program:
gcc -g -o a.exe a.c -lc -lcygwin
there are some question below:
/cygdrive/d/DOCUME~1/ADMINI~1/LOCALS~1/Temp/ccSmKP9B.o: In function `main':
