link error with modules fcntl + lib-symbol-visibility

Hi,

Im using the gnulib modules fcntl and lib-symbol-visibility (and many others) 
when building a shared library.

I get the following link error when linking a test tool:

/usr/bin/ld: test_linking: hidden symbol `rpl_fcntl' in 
../lib/libgnu.a(fcntl.o) is referenced by DSO

Would would be the right thing to avoid this error ?

I am on up-to-date Debian SID amd64 with a up-to-date gnulib.


Best regards

	Tim

[SOLVED] link error with modules fcntl + lib-symbol-visibility

Hi,

after finding --libtool option for gnulib-tool, everything became pretty 
clear. There were also several things to fix in the Makefile.am files.

BTW, do you suggest to invoke gnulib-tool twice for a project with library and 
tools combined ? (E.g. one with --libtool and both invocations having a 
different --source-base.)

Best regards

	Tim
