The ouput objects are being cached somewhere, and survive a reboot. They are
not in the Gnome wastebasket either (rm doesn't put them there).
Are you using ccache ?
Check out ~/.ccache
Thanks! This is correct, but I didn't see it advertised:
tar xvfj geos-3.9.0.tar.bz2
mkdir _build
cd _build
rm -rf ~/.ccache
cmake ../geos-3.9.0
# -- Check for working C compiler: /usr/lib64/ccache/cc - skipped
# -- Check for working CXX compiler: /usr/lib64/ccache/c++ - skipped
du -sm ~/.ccache
# 1 /home/rsb/.ccache
CCACHE_DISABLE=1 time make
# 8:24.54
du -sm ~/.ccache
# 1 /home/rsb/.ccache
cd ..
rm -rf _build
mkdir _build
cd _build
cmake ../geos-3.9.0
CCACHE_DISABLE=1 time make
# 7:32.33
du -sm ~/.ccache
# 1 /home/rsb/.ccache
cmake itself is also ccaching, but
CCACHE_DISABLE=1 time cmake ../geos-3.9.0
stops it. I put CCACHE_DISABLE=1 in a start-up file to be on the safe
side. Now, rm -rf _build does remove all traces of the build.
