Good afternoon all, This is the first time I've posted online seeking help and hope I haven't missed anything out. I am trying to use SQLite on an embedded system with an ARM9, running a closed proprietary Linux Real Time Operating System (based on the 2.6 Linux kernel). At the time of writing, I have successfully cross-compiled the SQLite binary for the embedded system, and can execute it remotely on the target system without a hitch.
However, my problems arise when I'm trying to write some C code to interface with SQLite. I've included sqlite3.h (generated when I cross-compiled SQLite) to my source code, and through my make file I have added libsqlite3.a to my lib path. I would normally develop on a Linux platform, but because the supplier of the CPU gave me a disc with corrupted data (and are not responding for requests for a new disc), I have to use their Windows XP toolchain and thus develop on a Windows XP system. The embedded system does not have a compiler on it or any of the GNU auto-configuration tools etc, so I compiled the source from /sqlite-3.7.2.tar.gz/ instead of the sqlite-amalgamation tarballs. My code consists of a chopped down version of the sample C code in : http://www.sqlite.org/quickstart.html. All my code does differently is hardcodes in some test values instead of reading off the input arguments and gives direct include call (ie #include "sqlite3.h" instead of #include <sqlite3.h>). I get the following error messages when attempting to compile my program : */cygdrive/c/Documents and Settings/boss/My Documents/sqlite cross compile/sqlite-eddybuild/libsqlite3.a(os_unix.o): In function `unixDlSym':* *../sqlite/src/os_unix.c:4871: undefined reference to `dlsym'* */cygdrive/c/Documents and Settings/boss/My Documents/sqlite cross compile/sqlite-eddybuild/libsqlite3.a(os_unix.o): In function `unixDlClose':* *../sqlite/src/os_unix.c:4875: undefined reference to `dlclose'* */cygdrive/c/Documents and Settings/boss/My Documents/sqlite cross compile/sqlite-eddybuild/libsqlite3.a(os_unix.o): In function `unixDlError':* *../sqlite/src/os_unix.c:4844: undefined reference to `dlerror'* */cygdrive/c/Documents and Settings/boss/My Documents/sqlite cross compile/sqlite-eddybuild/libsqlite3.a(os_unix.o): In function `unixDlOpen':* *../sqlite/src/os_unix.c:4830: undefined reference to `dlopen'* *collect2: ld returned 1 exit status* *make: *** [enst_core] Error 1* The makefile for my C code is as follows. *CROSS = /opt/lemonix/cdt/bin/arm-linux-* *LDFLAGS += -L/opt/lemonix/cdt/lib -L/opt/lemonix/cdt/bin* *IFLAGS += -I/opt/lemonix/cdt/include -I./include * *CFLAGS = -O2 -g -Wall -Wno-nonnull* *DEST = ../../ramdisk/root/sbin * *DEST_ETC = ../../ramdisk/root/etc* * * *CC = $(CROSS)gcc * *STRIP = $(CROSS)strip* *AR = $(CROSS)ar* * * *TARGET = test_core* * * *LIBS = -lrt SB_APIs/SB_APIs.a "/cygdrive/c/Documents and Settings/boss/My Documents/sqlite cross compile/sqlite-eddybuild/libsqlite3.a"* * * *all : $(TARGET) * *test_core : test_core.o* * rm -f $...@* * $(CC) $(CFLAGS) $(LDFLAGS) $(IFLAGS) -o $@ $...@.o $(LIBS)* * $(STRIP) $...@* * * *clean: * * rm -f *.bak *.o* * * *release:* * cp -f $(TARGET) $(DEST)* * cp -f sb_default_config $(DEST_ETC)* I can supply the makefile for my SQLite cross-compile as well if needed. I can't for the life of me work out where I've gone wrong or how to fix the problem! I assume it is the way I am using the C interface. Any help would be very much appreciated!
