#include <stdio.h> on Android clang causes an error

#include <stdio.h> on Android clang causes an error

[Lucy Phipps]

For example, building gzip 1.11 from the tar.xz source:
In file included from /home/builder/.termux-build/gzip/src/lib/freading.c:20:
In file included from /home/builder/.termux-build/gzip/src/lib/freading.h:18:

The problem is
The patch I ended up using on Termux is very simple, but assumes
gnulib didn't replace free()

since the official git repo's online viewer doesn't allow blame, the
commit causing it was 48ece5c3f2185f52ab8cd73ceac9bd9f0e01eac6

Thank you for reporting this problem. I attempted to fix this in Gnulib 
(see my recent email to you, archived at 
<https://lists.gnu.org/r/bug-gnulib/2021-09/msg00024.html>). If you have 
the time, please give the fix a try. You can do that either by building 
from the latest Git version of gzip on Savannah, or (this is probably 
easier) by building from the attached tarball which I just now generated 
from Savannah.

Re: #include <stdio.h> on Android clang causes an error

[Lucy Phipps]

this works, but there's an additional warning now:
/home/builder/.termux-build/gzip/src/lib/free.c:48:3: warning:
implicit declaration of function 'free' is invalid in C99
[-Wimplicit-function-declaration]
  free (p);
  ^

the only 2 warnings before were in strerror_r.c:
/home/builder/.termux-build/gzip/src/lib/strerror_r.c:205:9: warning:
incompatible pointer to integer conversion assigning to 'int' from
'char *' [-Wint-conversion]
    ret = strerror_r (errnum, buf, buflen);
        ^ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
/home/builder/.termux-build/gzip/src/lib/strerror_r.c:242:60: warning:

[-Wpointer-integer-compare]
        if (strerror_r (errnum, stackbuf, sizeof stackbuf) == ERANGE)
            ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ ^  ~~~~~~

Thank you for reporting the additional problems with 'free' and with 
'strerror_r'. I have theories as to why these problems occur, and have 
installed Gnulib patches that attempt to fix them (you should have 
recently received email containing these two patches).

I generated a new gzip tarball containing these patches (attached). I 
hope it fixes the warnings. Please give it a try.

Re: #include <stdio.h> on Android clang causes an error

[Lucy Phipps]

the strerror_r() warnings are still there, but this fixed the free() warning

Re: #include <stdio.h> on Android clang causes an error

[Paul Eggert]

Your latest report helped me find another portability problem. 
Ironically, a compatibility feature in Android API 23 intended to make 
it easier porting GNU software by assuming the GNU API for strerror_r, 
collided with a compatibility feature in Gnulib intended to make it 
easier to port GNU software by assuming the POSIX API for strerror_r.

I installed a Gnulib patch to fix that (you should have received email a 
few hours ago), and am attaching a revised gzip tarball. Please give it 
a try.

Thanks again for these reports. They should help make it easier to run 
several GNU programs on Android, not just gzip.

several gnu packages :)

Thanks indeed, to both of you.
This is good justification for making a new gzip release before long.
