Building DBD::Sybase, I want to add /usr/local/dept/lib to the RPATH in the .so. Defining CCFLAGS or LDDLFLAGS on the Makefile.PL command line doesn't work. Mr. Peppler suggested I try here. I will forward any fix to him for future versions.

• Is there another variable that works?
• If not, how to modify Makefile.PL such that LDDLFLAGS works?

A normal invocation produces a link command like this:

gcc     -L/usr/local/dept/lib \
        -shared \
        -O2 \
        -g \
        -pipe \
        -Wall \
        -Wp,-D_FORTIFY_SOURCE=2 \
        -fexceptions \
        -fstack-protector \
        --param=ssp-buffer-size=4 \
        -m64 \
        -mtune=generic Sybase.o dbdimp.o \
        -o blib/arch/auto/DBD/Sybase/Sybase.so

I can add the RPATH manually by relinking thus:

$ sh -x relink && readelf -d blib/arch/auto/DBD/Sybase/Sybase.so | gre
+p -i rpath
+ gcc -L/usr/local/dept/lib -Wl,-R/usr/local/dept/lib -shared -O2 -g -
+pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --p
+aram=ssp-buffer-size=4 -m64 -mtune=generic Sybase.o dbdimp.o -o blib/
+arch/auto/DBD/Sybase/Sybase.so
 0x000000000000000f (RPATH)              Library rpath: [/usr/local/de
+pt/lib]

but using LDDLFLAGS damages the command line:

$ perl Makefile.PL PREFIX=$DEPT/perl LDDLFLAGS=-Wl,-R$DEPT/lib < answe
+rs && rm -f nohup.out && nohup make || grep ^gcc nohup.out | tail -1
Unknown Client Library version - assuming FreeTDS.
