Unable to compile a new libcmd using nval library

[itn3rd77]

Hi,

I wanted to add a new command beneath src/lib/libcmd and added my command in the Mamfile. But I am failing with the build:

# src/cmd/builtin/Mamfile: 50-55: make %{INSTALLROOT}/dyn/bin/pty
+ LDFLAGS='  -Wl,-no-as-needed'
+ export LDFLAGS
+ cat /home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/lib/lib/cmd
+ dylink -e pty -lutil -lcmd -last -lutil pty.o
[dylink] + cc -Wl,-no-as-needed -o /home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/dyn/bin/pty pty.o -L/home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/dyn/lib -lutil -lcmd -last -lutil
/usr/bin/ld: /home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/dyn/lib/libcmd.so: undefined reference to `nv_open'
/usr/bin/ld: /home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/dyn/lib/libcmd.so: undefined reference to `nv_unset'
/usr/bin/ld: /home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/dyn/lib/libcmd.so: undefined reference to `nv_setvtree'
/usr/bin/ld: /home/itheiss/Workspace/ksh-dev/arch/linux.i386-64/dyn/lib/libcmd.so: undefined reference to `nv_isnull'
collect2: error: ld returned 1 exit status

As no commands beneath src/lib/libcmd are using nval library I guess there must be something added to the Mamfile to succeed. Is this a bad idea or can anybody give me a hint on how to resole this?

Thanks and best regards
Ingo

Those functions are provided by libshell.so, which is compiled after pty. You'll need to compile your command after ksh itself compiles, then link it against libshell (-lshell) to utilize the nval library.
