Linking fails on solaris

[ablaette]

Installing RcppCWB on Solaris fails, see the CRAN log. The problem occurs at the linking stage:

/opt/csw/bin/g++ -std=gnu++14 -shared -L/usr/local/lib -L/opt/csw/lib -o RcppCWB.so RcppExports.o cqp.o higher_level_functions.o utils.o -L/cl -L/cqp -L/utils -lcwb -lcqp -lcl
ld: fatal: library -lcwb: not found
ld: fatal: library -lcqp: not found
ld: fatal: library -lcl: not found
ld: fatal: file processing errors. No output written to RcppCWB.so

For some reason, statements on the path of static libraries are not passed into the linker command. It happens with RcppCWB v0.4.0, but not (yet) with RcppCWB v0.3.2.

The call for the linker looks as follows:

/opt/csw/bin/g++-4.9 -std=gnu++11 -shared -m32 -march=pentiumpro -L/opt/csw/lib -o RcppCWB.so RcppExports.o cqp.o higher_level_functions.o utils.o -L/cl -L/cqp -L/utils -lcwb -lcqp -lcl

It results from something going wrong when defining the PKG_LIBS variable:

printf "PKG_LIBS=-L%s/cl -L%s/cqp -L%s/utils -lcwb -lcqp -lcl %s %s %s %s\n" ${CWB_DIR} ${CWB_DIR} ${CWB_DIR} "$GLIB_LINKER_FLAGS" "$PCRE_LIBDIRS" ${SOCKETLIB} "$CARBON" >> ./src/Makevars

The problem is that SOCKETLIB may include a whitespace sign. The problem does not occur when $SOCKETLIB is wrapped in quotation marks as follows.

printf "PKG_LIBS=-L%s/cl -L%s/cqp -L%s/utils -lcwb -lcqp -lcl %s %s %s %s\n" ${CWB_DIR} ${CWB_DIR} ${CWB_DIR} "$GLIB_LINKER_FLAGS" "$PCRE_LIBDIRS" "$SOCKETLIB" "$CARBON" >> ./src/Makevars

And this is how the configure script is changed.
