Hi, Kay Roemer convinced my yesterday that I should try to strip mico as good as possible to get a slim version. I was very sceptical but here is what I did: 1) I removed IR from mico and commented out every piece of code using it. A hell lot of work :-( 2) Removed DynAny 3) Removed all the SSL Stuff 4) Removed the POA and its policy stuff 5) I wondered why buffer.pic.o was 20kB on Kays machine and 64K on my. Solution: Use mini-stl. This is no problem any more since we dont use STL in KOffice (almost). And here is what I got :-) a) An ORB that compiles on a single PII400 in 3min,10secs!!! b) [weis@teutates weis]$ ls -l /opt/mico/lib/libtinymico2.2.7.so -r-xr-xr-x 1 weis users 1826776 1.8MB !!!!! c) The size of the account example is 43kB instead of 100Kb now! With the real STL I got 2.6 MB and 100kB accont example. The rest of the optimization was done with mini-stl. As you can see STL sucks !!!!! I am soooooo happy :-) Bye Torben .... who got almost no sleep this night ....
