[Buildroot] external toolchain and iconv in libglib2.mk

[Buildroot] external toolchain and iconv in libglib2.mk

[Heiko Zuerker]

Hey,

 

I'm using crosstools-ng (configured as external toolchain) with iconv
support.

 

The host-libglib2 compile fails without the line:

HOST_LIBGLIB2_CONF_OPT += --with-libiconv=gnu

 

I'm not sure how to fix this correctly, any suggestions?

Hello Heiko,

It sounds like an host related problem...
Could you give us some more details about the distribution you're
using ?

I'm actually using an older version of linux-from-scratch in a chroot jail, in order to provide a controlled environment for the build.
It uses glibc 2.10.1 with iconv support enabled.

Ok, it seems the iconv detection fails...
Could you provide the config.log from the host-glib build directory ?

Somewhere on pastebin would be great...

[Buildroot] external toolchain and iconv in libglib2.mk

[Heiko Zuerker]

(sorry, this time with a reply to the list)

Hey,

Here's the error message:
gconvert.c:65:2: error: #error GNU libiconv not in use but included iconv.h is from libiconv

config.log without --with-libiconv=gnu 
http://pastebin.com/WB433xVu

config.log with --with-libiconv=gnu

Ok great,

It looks like something is wrong with your host. You do not seem to have
libiconv.so on your system, but still your /usr/include/iconv.h defines
a _LIBICONV_H.

So you might have a libc compiled with iconv support, but you're using
libiconv's header, that is strange...

Or maybe even more strange, you've got libc with iconv support and on
top of that you've installed libiconv, which is confusing glib...

I'm afraid you'll have to fix your system.

Regards,

Libiconv.so is there

Yes that was the issue. I copied iconv.h from glibc and now it works.

No worries, as long as I know what's going on, I can fix it.

Thanks for your quick help!
