<div>Hello Yocto.<br>
<br>
I am now trying to build autotool based (inherit autotool) recipe on Yocto 2.0 based environent.<br>
Howerver, I am seeng following error.<br>
I wonder if this is a known problem and you already have workaround?<br>
<br>
It says __init_array_end/start is not found which is referred in libc_nonshared.a(elf-init.oS).<br>
I googled and learned that this can happen if parameters are not set properly to g++ when building shared library, and in fact, if I remove '-lc' from the final linker command line, the build error is gone.<br>
<br>
>-lm -lc -lgcc_s -lgcc => NG<br>
>-lm -lgcc_s -lgcc => OK<br>
<br>
The problem is, these liker parameters are set by the configure script into libtool script and so far I could not find easy configurable option to explicity remove '-lc' from here.<br>
<br>
I think configure recognizes that '-lc' is not necessary to build shared library (through 'build_libtool_need_lc', etc. test), but it takes these from somewhere (from its tests or its default template?) and embedding to linker command parameters.<br>
<br>
This error did not happen with Yocto 1.8 based build (where the same recipe could built w/o break).<br>
So, it can be toolchain issue (c library difference, autotool difference, etc.) or libc quirk, maybe fixed problem in recent versions, or specific to my cross-environment, but I have not yet figured out handy workaround.<br>
<br>
I am trying here with protobuf package, butI am not yet sure if this happens with all of the autotool based packages.<br>
