I've been able to get ahead from this step: Building QGIS source code on Windows 7 - Not working
I'm trying to build the latest QGIS(2.10.1) using Visual Studio 10 Express but getting these unresolved symbols while building "ALL BUILD".
In the Cmake-gui I can see these variables as undefined: QWTPOLAR_INCLUDE_DIR and QWTPOLAR_LIBRARY.
Build configuration is set to Release.
I remember while building the solution itself it showed a couple failures.
All the unresolved symbols start with Qwt in "ALL BUILD" for example:
Creating library d:/build/src/gui/Release/qgis_gui.lib and object d:/build/src/gui/Release/qgis_gui.exp

My code:

How to I access external libs from Unity3d? Specifically CoreGraphics for CGDisplayScreenSize.
Define the ObjC return type, CoreGraphics.CGSize in terms a C# type and you will be fine.

The jena jars are not on the runtime class path of the webapp.
I am new to ANT and JUnit. As per the requirement i created 'JUnitTestCase' in Eclipse and call the requested test classes as per proper annotation.
While running the 'build.xml' file through 'Ant Build', it throws error as:
D:\ecllipse\eclipse\JunitTestProject>ant compile
Buildfile: D:\ecllipse\eclipse\JunitTestProject\build.xml
setClassPath:
init:

While looking back to JUnitTEstCase, i have imported the annotations like (import org.junit.After;import org.junit.Before and import org.junit.Test;). I, also, set build path for 'junit.jar'. I tried lot but couldn't figure it out. i am also attaching JUnitTest project as:
package jnuittestPckg;
import org.junit.After;
import org.junit.Before;
import org.junit.Test;
public class HelloWorldTest {
private HelloWorld hlwrd;
#Before
public void setUp() throws Exception {
hlwrd = new HelloWorld();
System.out.println("I am in Before");
}
#After
public void tearDown() throws Exception {
System.out.println("I am in After");
}
#Test
public void testClass1() {
hlwrd.Class1(null);
}
#Test
public void testClass2() {
hlwrd.Class2(null);
}
}
Please help me out.
You test.classpath property does not include the junit.jar.
Add it to the classpath and this issue will be resolved.
