Hello Alexio, A look into that SQLDBC package did show me that the linux shared library is missing some essential symbols (and thus will not work).
Until we make a more recent SQLDBC package available, your only chance is in using the static library that's also in the package, and apparantly contains all objects. So change in your compilation -L/home/myUser/sapdb-linux/lib -lSQLDBC to /home/myUser/sapdb-linux/lib/libSQLDBC.a Sorry for any inconvenience caused Alexander Schr�der SAP DB, SAP Labs Berlin > -----Original Message----- > From: Alexio Cassani [mailto:[EMAIL PROTECTED] > Sent: Wednesday, April 28, 2004 4:07 PM > To: [EMAIL PROTECTED] > Subject: I cannot reach libSQLDBC.so > > > Hi, > I'me developing a C++ library .so that will be installed on a > Linux box. > > The step I've followed are: > > 1) Wrote a C++ code > 2) Copied the libSQLDBC.o and libSQLDBC.a in /lib and /usr/lib > 3) Compiled my code with the following command: > gcc -shared -o libMyLib.so -I/home/myUser/sapdb-linux/incl > -I/usr/lib/j2sdk1.4.2/include -I/usr/lib/j2sdk1.4.2/include/linux > -L/home/myUser/sapdb-linux/lib -lSQLDBC myLibSourceCode.cpp > 4) As my library is accessed through a Java Native Interface > the running > command is the following: > java -cp myJavaApp.jar:junit.jar myJavaAppTest > (it's junit class test) > The output is the following: > > testMethod(myJavaAppTest)java.lang.UnsatisfiedLinkError: > /home/myUser/libMyLib.so: /home/myUser/libMyLib.so: undefined symbol: > _ZN6SQLDBC16GetClientRuntimeEPci > at java.lang.ClassLoader$NativeLibrary.load(Native Method) > at java.lang.ClassLoader.loadLibrary0(ClassLoader.java:1560) > at java.lang.ClassLoader.loadLibrary(ClassLoader.java:1456) > at java.lang.Runtime.load0(Runtime.java:737) > at java.lang.System.load(System.java:811) > ... > ... > > I've tried to compile and execute the HelloWorld application > I've found in > the sapdb-sqldbc-linux-32bit-i386-7_4_4_3beta.tgz archive > (the libSQLDBC.so > and .a I'm using are in this tgz) and the error is similar. > Moreover the > original version of this code was developed under Windows > (instead of a .so > there is, obviously, a dll) and it works fine. > The system on which I'm developing/testing is a Debian and > the SapDB which I > should connect to is a 7.4.03 > > Any suggestion? > > TIA > Alexio > > > -- > MaxDB Discussion Mailing List > For list archives: http://lists.mysql.com/maxdb > To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED] -- MaxDB Discussion Mailing List For list archives: http://lists.mysql.com/maxdb To unsubscribe: http://lists.mysql.com/[EMAIL PROTECTED]
