- I encountered the problem using gcc 2.3.1 on SS2 SUNOS 4.1.2.
- I compiled the folowing program using gcc2.3.1 and cc and run
- under the Openwindow2.0's comannd tool. I expected
- the result is the same, but not.
-
- % cat ttt.c
- #include <stdio.h>
- #include <stdlib.h>
- #include <sys/ioctl.h>
- #include <sgtty.h>
-
-
- #define EXIT_OK 0
- #define EXIT_FAILURE 1
-
-
- main()
- {
- struct sgttyb arg;
-
- if (!isatty(fileno(stdin))) {
- fprintf(stderr, "stdin is not tty\n") ;
- exit(EXIT_FAILURE);
- }
- fprintf(stderr, "tty name is %s\n", ttyname(fileno(stdin))) ;
- if (ioctl(fileno(stdin), TIOCGETP, (char *)&arg) < 0) {
- perror("ioctl - TIOCGETP");
- exit(EXIT_FAILURE);
- }
- fprintf(stderr, "We can do ioctl\n") ;
- exit(EXIT_OK);
- }
-
- The config.status of gcc is the following.
-
- % cat config.status
- #!/bin/sh
- # GCC was configured as follows:
- ./configure --target=sparc-sun-sunos4.1 --prefix=/usr/gnu
- echo host=sparc-sun-sunos4.1 target=sparc-sun-sunos4.1 build=sparc-sun-sunos4.1
-
- And the script of the result is the following.
-
- % gcc -v -o ttt.gcc ttt.c
- Reading specs from /usr/gnu/lib/gcc-lib/sparc-sun-sunos4.1/2.3.1/specs
- gcc version 2.3.1
- /usr/gnu/lib/gcc-lib/sparc-sun-sunos4.1/2.3.1/cpp -lang-c -v -undef -D__GNUC__=2 -Dsparc -Dsun -Dunix -D__sparc__ -D__sun__ -D__unix__ -D__sparc -D__sun -D__unix ttt.c /tmp/cca11931.i
- GNU CPP version 2.3.1 (sparc)
- /usr/gnu/lib/gcc-lib/sparc-sun-sunos4.1/2.3.1/cc1 /tmp/cca11931.i -quiet -dumpbase ttt.c -version -o /tmp/cca11931.s
- GNU C version 2.3.1 (sparc) compiled by GNU C version 2.3.1.
- as -o /tmp/cca119311.o /tmp/cca11931.s
- /usr/gnu/lib/gcc-lib/sparc-sun-sunos4.1/2.3.1/ld -e start -dc -dp -o ttt.gcc /lib/crt0.o -L/usr/gnu/lib/gcc-lib/sparc-sun-sunos4.1/2.3.1 -L/usr/gnu/lib /tmp/cca119311.o -lgcc -lc -lgcc
-
- % ttt.gcc
- tty name is /dev/ttyp4
- ioctl - TIOCGETP: Inappropriate ioctl for device
-
- And the result of the default SUN cc is the following.
-
- % cc -v -o ttt.cc ttt.c
- /lib/cpp -undef -Dunix -Dsun -Dsparc ttt.c >/tmp/cpp.11939.0.i
- /lib/ccom - </tmp/cpp.11939.0.i >/tmp/ccom.11939.1.s
- rm /tmp/cpp.11939.0.i
- /bin/as -o ttt.o -Q /tmp/ccom.11939.1.s
- rm /tmp/ccom.11939.1.s
- /bin/ld -dc -dp -e start -X -o ttt.cc /usr/lib/crt0.o ttt.o -lc
- rm ttt.o
-
- % ttt.cc
- tty name is /dev/ttyp4
- We can do ioctl
-
-
- I hope this information is useful to you.
