I am trying to get to grips with CBuilderX and am having trouble building
one of the demo files from the "glibcrypt" distribution. The error I get on
building is

undefined reference to 'gpg_strerror(unsigned)' at line 224

This is defined in gpg-error.h. The source has the line

include "/usr/local/include/gpg-error.h"

and in that file is the definition

const char *gpg_strerror (gpg_error_t err);

I know the symbol is present in the library;

[root@splosh craig]# nm /usr/local/lib/libgpg-error.so |grep
gpg_strerror
00000990 T gpg_strerror
00000af0 T gpg_strerror_r
[root@splosh craig]#

So why doesn't it build? I have tried adding various paths to various
options and the command that's being used to build (link?) the app is

g++ -B/usr/local/include -L/usr/local/lib -o
/usr/NETDRIVE/Work/linux/Debug_Build/ConsoleApp1 linux/Debug_Build/basic.o
/usr/local/lib/libgpg-error.so /usr/local/lib/libgcrypt.so.7

First I added the specific files at the end, then I added /usr/local/include
and /usr/local/lib to the search paths. Neither gets rid of the problem.
This is probably something very simple because I've never built things
before on Linux (aside from downloaded stuff that does it itself!).
