Bug #12906: Configure appends extra -l with libjpeg test

From: ron@csu.concordia.ca Operating system: Caldera Linux PHP version: 4.0.6 PHP Bug Type: Compile Failure Bug description: Configure appends extra -l with libjpeg test On a clean php-4.0.6 distribution, (untar the file and then cd to the directory) the following configure command causes problems: ./configure --with-mysql --with-apache=../apache_1.3.12 --enable-track-vars --with-gd=/usr/local --with-jpeg-dir=/usr/local --with-xpm-dir=/usr/X11R6 checking whether to include GD support... yes checking whether to enable truetype string function in gd... no checking for the location of libjpeg... yes checking for jpeg_read_header in -ljpeg... no configure: error: libjpeg not found! Here is the config.log entry: --------- CUT HERE ------ configure:17964: checking for jpeg_read_header in -ljpeg configure:17985: gcc -o conftest -g -O2 conftest.c -ljpeg -L/usr/local/lib -l -lcrypt -lresolv -lm -ldl -lnsl -lresolv 1>&5 /usr/i386-linux/bin/ld: cannot open -l-lcrypt: No such file or directory configure: failed program was: #line 17974 "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 jpeg_read_header(); int main() { jpeg_read_header() ; return 0; } --------- CUT HERE ------ Note the extra -l with no library before -l crypt. This is what is causing the test to fail, despite the jpeg library having being isntalled correctly. Compiling the same test program without the extra -l succeeds. Thanks! Ron. P.S. Are there any workarounds to this problem? I'm still trying to figure out which part of the configure command is adding the extra -l. -- Edit bug report at: http://bugs.php.net/?id=12906&edit=1
