Hi, I'm using the boost library filesystem on Windows XP and Solaris 9 and 10. I haven't had any problems with Windows so far. When linking my executable on Solaris 9, the linker warned me that the filesystem library I linked wanted to be linked with libm.so.2, which isn't on my Solaris 9 system. The executable still runs but when I use filesystem to list the files in a directory it doesn't list all of them. I was able to link on Solaris 10, but there I am getting a core dump when I run. Has anyone ever had similar problems on Solaris? thanks, matthew
