Date: 01/07/01

From: muhlig <email protected>
Operating system: Solaris 2.6
PHP version: 4.0.4
PHP Bug Type: Compile Failure
Bug description: configure fails while checking for gzgets

./configure --with-mysql=/usr/local --with-apache=../../apache/apache_1.3.12 --with-zlib=/usr/local/lib --with-ldap=/usr/local/ldap --enable-track-vars --enable-magic-quotes --enable-bcmath

...
checking whether to include zlib support... yes
checking for gzgets in -lz... no
configure: error: Zlib module requires zlib >= 1.0.9.

Of course zlib 1.1.3 is properly installed.

from config.log:

...
configure:43634: checking whether to include zlib support
configure:43835: checking for gzgets in -lz
configure:43854: gcc -o conftest -g -O2 -D_POSIX_PTHREAD_SEMANTICS -DXML_BYTE_O

configure: failed program was:
#line 43843 "configure"
#include "confdefs.h"
/* Override any gcc2 internal prototype to avoid an error. */
/* We use char because int might match the return type of a gcc2
    builtin and then its argument prototype would still apply. */
char gzgets();

int main() {
gzgets()
; return 0; }

from configure:

...
LIBS="-lz $LIBS"
cat > conftest.$ac_ext <<EOF
#line 43843 "configure"

Obviously the source of the problem is library order during link phase. I was able to workaround the problem changing LIBS line above to:

LIBS="-$LIBS -lz"

However it is probably not the proper solution, please find better one.
