Is there a way to output the verbose log to build.log, but show the
shortened log to the terminal? The non-verbose build is quite useful
for seeing the actual warnings as they fly by rather than the entire
gcc/libtool command, which is often mostly noise.

And writing to std{out,err} is expensive! ;-)

In fact, there's already bug 379497 [1] open for this. Some build
systems might use the variable V for something else, so adding
--disable-silent-rules may be the safer solution.

Yeah, please use the correct configure opt rather than throwing in
random makevars.

Of course --disable-silent-rules is the way to go for autotools based
packages.

I don't want to throw any vars blindly to emake. V=1 was just an example
that I've seen in some packages' build systems. It was more like a
proposal to use whatever build system of given package provides.

That's usually because users sometimes attach only "relevant" parts of build
log (well, relevant according to their taste = last lines, even when they use
parallel compilation).
Any particular example of bug report with entire build log from cmake-utils in
fancy mode, and still being unable to locate the problem?

I ask, because we're appending summary just after configure phase to make
vorbose logging of whole build process unecessary.

Yeah take bug 297699 as an example and relavant snippet:

Linking CXX executable eqsl
[ 22%] CMakeFiles/eqsl.dir/eqsl.cxx.o: In function `callback(char
const*)':
eqsl.cxx.text+0x192a): undefined reference to `Fl::lock()'
eqsl.cxx.text+0x1ef1): undefined reference to `Fl::unlock()'

As we don't see actual linking we cannot immediately tell what libraries
were linked and rule out/diagnose as-needed issue. As I cannot even
reproduce the bug right now I can only rely on clairvoyance to figure
what happened there...

Cheers,
Kacper

I think you're confusing build log with build output.

How are you supposed to debug a compile or linker error without the compiler
command line?

That could be done, but I'd advise to make sure our users know that the
could have a quiet/silent output from portage.
