Hello,
I work with TinyOS-2.x installed under cygwin, and I have a mysql server
installed into Windows 7.
I want to make a connection to a database created in MySQL from a component
nesc, actually I want the application BaseStation connects to the mysql
database
to verify that an identifier of a node exists or not.
For this I have already written a C program that makes the database connection
and verify that such identifierexists or not, then I run this program with gcc
command in cygwin linking libmysql.dll library:
gcc test.c -lmysql
$ make telosb
I know that these errors are the result of the non-linkage with libmysql.dll
how to make a linkage with a library in nesc?
Please help me.it works without error but when I copy the code of test.c into
BaseStationP.nc and after adding this line in the makefile of BaseStation
CFLAGS + = -L/usr/local/lib-shared-lmysql : to make the linkage with
libmysql.dll
that produced the following errors:
/cygdrive/c/Users/Amira/AppData/Local/Temp/ccUTU6G6.o: In function `BaseStationP
