[Buildroot] Need iconv(): fatal error: iconv.h: No such file or directory

[Williams]

Hi All,

I am working with a package that needs  iconv()

How can I get this in buildroot?

Here is my error:
fatal error: iconv.h: No such file or directory


Cheers,
Ernest

iconv is either provided by your toolchain (if it has locale support),
or by libiconv. So, your package should do in its Config.in file:

	select BR2_PACKAGE_LIBICONV if !BR2_ENABLE_LOCALE

and in the .mk file:

ifeq ($(BR2_PACKAGE_LIBICONV),y)
<pkg>_DEPENDENCIES += libiconv
endif

Best regards,

Thomas

Hi Thomas,

In this case my package/application is external to buildroot.

I have set the following  in my  ".config"   using  make xconfig:
BR2_TOOLCHAIN_BUILDROOT_LOCALE

Like so,
BR2_TOOLCHAIN_BUILDROOT_LOCALE=y

After typing make, I expect to see  "iconv.h"  in ${STAGING_DIR}/usr/include
But it is not, there.  :(

Must, I rebuild everything from scratch ?

Cheers,
Ernest

Yes.

See http://buildroot.org/downloads/manual/manual.html#full-rebuild:

"""
When the toolchain configuration is changed, a complete rebuild
generally is needed. Changing the toolchain configuration often
involves changing the compiler version, the type of C library or its
configuration, or some other fundamental configuration item, and these
changes have an impact on the entire system.

Okay, let the rebuild commence as I head to "Starbucks"  :)

Hint: use external toolchains.

Or buy a lot of coffee at Starbucks :)
