[uClibc] A stupid question.

[Henri van Riel]

Hello,

I hope the subject of this email is clear to everyone ;)

My question is about library sizes.

I have a uClibc-based target system build with a certain set of
options, I have the .config of that system. I also know what kernel it
is compiled and I also have that .config.

So I have recreated the environment on which my target was build and
I'm building a buildroot with the same settings. Same kernel headers
and kernel .config, same uClibc version and .config, the same target
arch and the same compiler. But my libraries are slightly smaller than
the ones on my target.... how can that be?

This is a comparison of the libraries of my target and dev system:

lib                   target         host
-------------------   ------       ------
ld-uClibc-0.9.26.so    16468        16436
libcrypt-0.9.26.so      9036         9036
libdl-0.9.26.so         5748         5716
libm-0.9.26.so         51532        51360
libnsl-0.9.26.so        1592         1560
libresolv-0.9.26.so     1592         1560
libuClibc-0.9.26.so   191180       190956
libutil-0.9.26.so       4252         4216

I warned you, this is probably a stupid question... but why aren't
those libraries equally big? I've checked them with readelf and the
libraries are identical when it comes to included symbols and stuff,
but some symbols are simply 1 or 2 bytes smaller. Why is that?
