Is the compiler/linker called from Eclipse any faster than run through a standard make operation? I would just like to know what the advantages are for using the Linux toolchain, since things seem to be working for the most part using the native toolchain. > >- Program I/O does not appear in the console, even though a console is > >allocated when the program starts.

Could > you provide me with a small Eclipse project that reproduce this? Aha, I just realized all my output was via stderr. I assume the difference is the change described in ports/java/eclipse-cdt/files/patch-cdt.core-openpty.c which changes a call from getpt() to posix_openpt(O_RDWR). I can't seem to find any reference to getpt() anywhere. I also couldn't find the libpty.so or libspawner.so anywhere in the 5.0.1 CDT jars, so they must have changed this drastically. About the closest things I could find was located in org.eclipse.cdt.core_5.0.1.200809120802.jar: org/eclipse/cdt/utils/pty/ org/eclipse/cdt/utils/pty/PTY$MasterFD.class org/eclipse/cdt/utils/pty/PTY.class org/eclipse/cdt/utils/pty/PTYInputStream.class org/eclipse/cdt/utils/pty/PTYOutputStream.class org/eclipse/cdt/utils/spawner/ org/eclipse/cdt/utils/spawner/EnvironmentReader.class org/eclipse/cdt/utils/spawner/ProcessFactory.class org/eclipse/cdt/utils/spawner/Spawner$1.class org/eclipse/cdt/utils/spawner/Spawner$Reaper.class org/eclipse/cdt/utils/spawner/Spawner.class org/eclipse/cdt/utils/spawner/SpawnerInputStream.class org/eclipse/cdt/utils/spawner/SpawnerOutputStream.class Is there any chance that we could push a patch upstream to the CDT group? I like the idea of using eclipse's software updates over a separate FreeBSD port per project. Also, I'm not sure what to patch at this point since much has changed since CDT 3.1.2. > >- Auto-build does not work as expected.

I'll try to setup a small project and see if I can find something. I've grown accustomed to the autobuild when working with Java that I'd like to see it work here too.
