         I'm trying to compile Konqueror/Embedded for ARM-Linux. Here 
are the steps I followed

1. Downloaded konqueror3-embedded-0.2-20051128.tar, as my KDE version is 
3.4 , I have Slackware Linux version 10.2 ( Linux 2.4.31), it has qt-3.3.4.
2. I also have Qtopia Core commercial version 4.2, which I have 
configured for ARM-Linux  and QT/X11 version 4.2 installed on my PC.

a) First Question is what exactly should be my configuration if I want 
to run Browser on Application based on Qtopia Core 4.2 ?

b) I tried to configure by ./configure --build=i686-linux 
--host=arm-linux --enable-embedded

              It gives me below error

          " checking for libz... configure: error: not found.
             Possibly configure picks up an outdated version
             installed by XFree86. Remove it from your system.

              Check your installation and look into config.log   "

                         In one of the old mail archives I saw 
suggestion to download package from 
http://handhelds.org/~llornkcor/devZone/cross-arm-extra.tgz 
<http://handhelds.org/%7Ellornkcor/devZone/cross-arm-extra.tgz> contains 
libz for arm.  I downloaded and copied files to my toolchain directory 
it still gives me same error.
 
   Please let me what need to be done to configure correctly . Any 
suggestion would be appreciated .

      Is it mandatory to have X11 along with our toolchain in order to 
compile  Konqueror/Embedded ?

        I found the answer.  With or without X11 depends on  
Konqueror/Embedded configuration  ./configure --enable-embedded will 
make sure Konqueror/Embedded will compile without X11.

      I was able to resolve libz problem.

Here is what I did for my ARM-Linux toolchain

1. Download libz from  http://www.zlib.net/

2. ./configure --prefix=/usr --shared
    make LDSHARED="arm-linux-gcc -shared -Wl,-soname,libz.so.1" 
CC_FOR_BUILD="arm-linux-gcc" \
   CC="arm-linux-gcc" LD="arm-linux-ld" CPP="arm-linux-g++ -E" 
AR="arm-linux-ar rc" \
   prefix=$(TOOLCHAIN_TARGET_DIR) CFLAGS="-fPIC" libz.so.1.2.3 libz.a
   make install # as root if required

3. Copy  zconf.h zlib.h from $(ZLIB_SRC_DIR) to 
$(TOOLCHAIN_TARGET_DIR)/arm-linux/include/


I also faced problem with libjpeg solution was similar

1. Download libjpeg from http://freshmeat.net/projects/libjpeg/

2.  CFLAGS="-D_REENTRANT -O2 -Wall" ./configure --prefix=/usr 
--mandir=/usr/share/man --enable-static \
 --enable-shared --build=$(TOOLCHAIN_TARGET_DIR) --host=arm-linux
 make CC="arm-linux-gcc" AR="arm-linux-ar rv" AR2="arm-linux-ranlib" 
CXX="arm-linux-g++"
 DESTDIR="$(TOOLCHAIN_TARGET_DIR)"

3. Copy  jconfig.h jmorecfg.h jpeglib.h from $(JPEG_SRC_DIR) to 
$(TOOLCHAIN_TARGET_DIR)/arm-linux/include/


                  Hope this helps.
