You compiled it on a computer with SW91 solibs and SW71 glibc?

Yes. But the requirement for SW91 solibs defeats the whole
purpose of mixing the two versions. It would be better to use
both SW91 solibs and glibc, as the SW91 glibc is much
smaller.

glibc glibcso binutils (g)make egcs/gcc+gcc-g++
7.1 2.1.2 22M 750K 1.5M 278K 2.95.2 3.1MB
8.1 2.2.5 24M 1.3M 2.4M 303K 2.95.3 1.7+1.8=3.5MB
9.1 2.3.2 14M ! 1.0M 3.1M 342K 3.2.3 3.4M+4.5M=7.9M

I can't see any reason not to upgrade to SW91 glibc. How did they actually get it smaller?

I had to upgrade to SW81 binutils to get 'as' to work.
An extra 600 to upgrade to SW91 binutils.

Why has gcc become so much larger? I save 8MB by upgrading glibc, then lose 5MB by upgrading gcc, from SW71 to SW91?


Can I compile for SW91 solibs (dynamically) if I have that plus an earlier
glibc, having first deleted glibc, installed the later solibs, then
reinstalled glibc older than the solibs?

I guess so. I installed the two libraries in the opposite order: SW71
glibc first, then SW91 solibs.

I will switch to SW91 glibc 2.3.2. And use precompiled gcc 3.2.3.

glibc-2.3 solibs is only 150k larger than glibc-2.1.

Did I read this wrong? I copied down 1024K (2.3.2) vis 757K (2.1.3)
Closer to 275K.

It is the full glibc which is a lot bigger.

glibc-2.3 full glibc is much smaller than glibc-2.1 full glibc.
8MB smaller, amazingly. Did they leave out older hardware?
