Libextractor:Cross compilation Error

[Tomy Joseph]

Hi,
I tried the following steps to cross compile Libextractor:
1: ./configure target=mips-linux --host=mips-linux build=i686-pc-linux-gnu
--prefix=/home/tomy/File/extractor (Tried without :build=i686-pc-linux-gnu
)
2: make : this time I am getting the following errors:
=======================================
In file included from extractor.c:21:
../../src/include/platform.h:60:19: iconv.h: No such file or directory
==========================================================
During Configuration I got the following logs regarding iconv:
===================================================
checking for iconv... no, consider installing GNU libiconv

checking iconv.h usability... no
checking iconv.h presence... no
checking for iconv.h... no
========================================================

but in normal x86 Compilation I found that all the checks for iconv is
yes...

Could you please tell me the exact problem??  Also I tried with Configure
options like --with-libiconv-prefix[=DIR] --without-libiconv-prefix..

LE generally does not cross-compile; I was not aware that iconv was a problem,
but the generated code for the printable-extractors certainly prevents
cross-compilation at this point (you can disable those with
the --disable-printable).

My best guess for the iconv problem is that your cross-compiler looks for
iconv.h in a different location and does not find it there.

Good luck!

Hi,
I have cross compiled libiconv and then linked the libraries with libextractor. But still I am getting errors related to iconv.

I tried the following steps to cross compile Libextractor:
./configure --target=mips-linux --host=i686-pc-linux-gnu --prefix=/home/tomy/libextr/ --disable-printable --with-libiconv=yes --with-libiconv-prefix=/home/tomy/libiconv/ (This directory contains all iconv libs,bin etc.)

But during make...

Hi,

It looks like you missed another library : libltdl (the first line of your post)
Try to compile with adding "--enable-ltdl-install" while configuring libextractor...
Here, my configuration line (which work for powerpc cross-compilation)

./configure --prefix=%{_prefix} --host=i686 --build=powerpc-linux \
   --enable-glib --enable-ltdl-install --with-libiconv-prefix=$DEV_IMAGE/usr \
   --disable-printable --disable-glibtest --disable-gtktest

Hope this will help !

Hum,
Is the error about libltdl still there ?
If yes, you'll probably need to add this library (cross compilation, etc...)

I hope that this library will also fix the libiconv problem, cause it defines some useful open/close function, that may break iconv...

Let me know how it works !

Well...
So, is the libltdl problem solved ?

It still looks like that the libiconv.so isn't found by ld.
Is the -L/smb/josepht/libiconv/lib/ path correct ?
Does this directory contains libiconv.so/libiconv.so.x/libiconv.so.x.y.z/libiconv.a ?

Have a look at that point, and tell me what's happen !

Hi,
About libiconv error, strongly I believe that it is there in Configuration . Because We can see the same error in config.log file. If u have some free time please do a final check..
