Subject: Declaring variables mid-function
Date: Sat, 18 Dec 1999 15:01:00 -0000 [thread overview]
Message-ID: <385c11fa@oit.umass.edu> (raw)
I am writing a medium sized program, and ran into a problem where gcc
would not compile any function that did not have all of its variables
declared as the first lines of the function. As a test, I wrote this small
program:
int test(char *tst, char *tst2, char **tst3);
int test2(void);
int main()
{
test2();
char *tst;
char *tst2;
char *tst3;
test(tst, tst2, &tst3);
return 1;
}
int test(char *tst, char *tst2, char **tst3)
{
return 21;
}
int test2(void)
{
return 21;
}
When trying to compile this, seemingly simple program, gcc complains. This
is the output:
bash-2.03$ gcc test.c -o test
test.c: In function `main':
test.c:8: parse error before `char'
test.c:12: `tst' undeclared (first use in this function)
test.c:12: (Each undeclareed identifier is reported only once
test.c:12: for each function it appears in.)
test.c:12: `tst2' undeclared (first use in this function)
test.c:12: `tst3' undeclared (first use in this function)
Does anybody have any idea what is going on here? My system is a Pentium,
with 48 MB ram, running Slackware Linux 7.0, gcc version 2.91.66 (egcs).
Thank you in advance!
