系统

cl@ns /web/work/dlang# uname -v
FreeBSD 7.0-CURRENT #0: Tue Oct  9 14:31:03 CST 2007     cl@ns.xwall.cn:/usr/obj/usr/src/sys/changlong

没问题，连接的时候就错了。

貌似 FreeBSD7 还没发布啊？自己编译GDC试试？估计现在没人能帮上忙。

gdc里面有个lib64目录,把里面的libphobos拷到/usr/local/lib下就可以了.

先谢谢楼上2位的关注，

我搜索libgphobos.a只发现了一个。 搜索带phobos名字的文件有下面2个。其中第一个不是库文件，但是有可执行权限。
./include/d/4.1.3/x86_64-portbld-freebsd7.0/phobos-ver-syms
./lib/libgphobos.a

执行后有以下警告

cl@ns /usr/local/include/d/4.1.3/x86_64-portbld-freebsd7.0# /usr/local/include/d/4.1.3/x86_64-portbld-freebsd7.0/phobos-ver-syms

GNU_BsdSockets_salen: not found
GNU_CBridge_Stdio: not found
GNU_Unix_Have_MMap: not found

x86目录下有以下文件

cl@ns /usr/local/include/d/4.1.3/x86_64-portbld-freebsd7.0# find . -name "*"
./gcc
./gcc/config.d
./gcc/configunix.d
./phobos-ver-syms

在gdc编译目录搜索到的libgphobos.a复制过去问题依旧。

cl@ns /usr/ports/lang/gdc/work# find . -name "*phobos*"

这个ports我刚才在i386下编译了下，没有任何问题。在google上找一些人说是amd64连接有问题，具体的解决方法没找到。

噢.我是在64位linux下测试的,freebsd没测试过.
