I recently encountered extremly slow compilation and linking times with g++ 4.1 and ld 2.16. Suprisingly, on a different (and slower) machine with g++/gcc 3.4 and ld 2.15 compiling and linking was much faster (easily with a factor of 10 to 20). Since it slowed down the development, it was really annoying. So I was looking around on the web to find some fixes or help. I also tried newer versions of ld and g++, but it didn’t really change anything. Interestingly the CPU usage during linking was down at 2-3%. So finally I found the bottleneck with our NFS which caused a slow-down when using the option -m32 during linking (I’m on a 64 bit machine compiling in 32 bit, so I need this option). I found another bottleneck with the assembler (as) also caused by using NFS. Compiling to a file in the network (i.e., not local) slows down the assembler quite a bit. So as a workaround one should try to compile intermediate object (.o) files as well as to link object files to executables to some place in the local file system (i.e., the file given by the option -o should be somewhere locally).

I thought I should just put this note online, it might save some of our time in case you’re experiencing similar problems :).

This weekend we have been the first time for this year skiing! Snow conditions were not too bad, although there were some bad parts on the tracks with smaller (and bigger) stones. This is not that nice. Appart from that it was great. Check out the photo gallery for pictures. Also have a closer look at the picture .. remember I bought a snowboard, this is the one you can see on the picture (I like yellow).

I put a small photo gallery online .. see it’s the last link on the left side. There are not yet a lot of photos online, but it will be filled with the time.

Here are two new songs written by me. I finished them the end of last year. The first one is called A Quite Thought. It has been recorded with a Sandberg nylon acoustic guitar, a Seagull acoustic western guitar, with a Line 6 POD Xt Live and a Dillion guitar (and a Samba Egg) .. again using GarageBand.

The second one is called Close Steps. Similar setup, no Sandberg (and no Samba Egg) and with strings from GarageBand.

Wonderful .. looking out of the window this morning, we saw snow in Grenoble. The temperature dropped these days and it already started snowing yesterday evening. Now we can look forward to go skiing. Haven’t checked out the snow conditions in the skiing resorts, but it should be ok, I guess.
