 Posted: Fri Jun 13, 2008 8:05 pm Post subject: ccache help [Solved] |
 |
|
I'm trying to set up ccache using our wiki http://gentoo-wiki.com/TIP_Use_ccache
i "emerge -av dev-util/ccache"
Followed the wiki and checked:
| Code: |
# ls -l /usr/lib/ccache/bin
total 0
lrwxrwxrwx 1 root root 15 Jun 14 01:04 c++ -> /usr/bin/ccache
lrwxrwxrwx 1 root root 15 Jun 14 01:04 g++ -> /usr/bin/ccache
lrwxrwxrwx 1 root root 15 Jun 14 01:04 gcc -> /usr/bin/ccache
lrwxrwxrwx 1 root root 15 Jun 14 01:05 i686-pc-linux-gnu-c++ -> /usr/bin/ccache
lrwxrwxrwx 1 root root 15 Jun 14 01:05 i686-pc-linux-gnu-g++ -> /usr/bin/ccache
lrwxrwxrwx 1 root root 15 Jun 14 01:05 i686-pc-linux-gnu-gcc -> /usr/bin/ccache
|
And
| Code: |
# cat /etc/make.conf
--- cut ---
FEATURES="fixpackages parallel-fetch ccache"
CCACHE_DIR="/var/tmp/ccache"
CCACHE_SIZE="2G"
|
After an emerge --sync, i found portage needed updated, so after an emerge portage
| Code: |
# CCACHE_DIR="/var/tmp/ccache" ccache -s
cache directory /var/tmp/ccache
cache hit 0
cache miss 0
files in cache 0
cache size 0 Kbytes
max cache size 2.0 Gbytes
|
Ok, so maybe the 1st time it was doing the caching, so there could not be any cach hits, so emerge portage again and:
| Code: |
# CCACHE_DIR="/var/tmp/ccache" ccache -s
cache directory /var/tmp/ccache
cache hit 0
cache miss 0
files in cache 0
cache size 0 Kbytes
max cache size 2.0 Gbytes
|
Same results 
Next part of the howto is genkenal and non-portage - that doesn't help. i think i need the portage stuff working 1st before i worry about genkernel.
Cheers

Did you symlink /root/.ccache
| Code: | mv /root/.ccache /root/snafu.ccache
ln -s /var/tmp/ccache /root/.ccache |
I think ccache is for C, and to my knowlwdge portage is mostly in python.
When you get to emerging system logger and grub etc.. you will see that it works.  |

I didn't do this:
| Code: |
mv /root/.ccache /root/snafu.ccache
|
But is this link the right way round? (does it even matter? a links a link right?)
| Code: |
# ls -alF /var/tmp/|grep ccache
lrwxrwxrwx 1 root root 13 Jun 14 01:09 ccache -> /root/.ccache/

It has to look like this | Code: | # ls -l /root/.ccache
lrwxrwxrwx 1 root root 15 Apr 18 23:53 /root/.ccache -> /var/tmp/ccache |
The commands to do it is | Code: | mv /root/.ccache /root/snafu.ccache
ln -s /var/tmp/ccache /root/.ccache |
After you do that it should work fine.  |

I set up the link properly re-emerged portage and the same results. Still looks like it's not working.
Did an emerge -uDaN world and it is working.
So looks like portage was not being cashed - don't know why - but looks like its working aways.

That's because portage is *not* written in C or C++.
