Hi, I have a few problems with the gnu stdc++ implementation in FBSD V2.2.5. Problem 1. The compilation speed of gcc seems to be very slow when I inlude templates from stdc++. The application so far is only a few hundred line long, but it takes at least 5 minutes to compile. Normally gcc is very quick. The resulting application is also much larger than I would expect. (about 250K). The application run speed is not slow, but it is not what I expect based on previous experience with FBSD on my machine. Problem 2 The gnu stdc++ implementation does seem to be missing quite a few things. The omission hurting most now is no mem_fun_ref. I can work around this by writing my own looping with iterators, but it rather defeats the point of the library. There are other omission like correct name spaces. I notice there are a number of STL implementations such as the SGI one. Has anyone tried porting this to FBSD and are they any better? Is gcc 2.7.x really up to it? I notice that visual c 5 seems to have a fairly complete implementation of stdc++, so I will continue development using NT. At some point I do need to run this code using gnu under FBSD as that is my first target platform. Regards Richard .......
