editor highlights syntax error that is not

Kurt,

Could you please check if this is reproducible in a new workspace with CCS 5.1? I don't see syntax errors with this code snippet.

Also check your settings under Project Properties->C/C++ General->Code Analysis->Launching. The "Run with build" and "Run as you type" settings should be unchecked.

1) yes, I still get the error with a new workspace. does your code build? I did not see the syntax error until I pointed to the Unity include files and ran a build.

2) I do not see "C/C++ General" at the top level of Project | Properties. 

My code does not build, I get other identifier undefined errors with the provided code snippet, but there are no syntax errors in the editor. If you can send me your source file(s) I can see if I can reproduce the issue.

You would need to click on the "Show Advanced Settings" at the bottom of the Properties page to see C/C++ General.

1) You have to be able to build.  That is why I gave you the reference to Unity. Download Unity.  Add unity/src and unity/extras/fixture/src directories to your Include path.

here is my complete source code:

#include "unity_fixture.h"

TEST_GROUP(Test01b_Init);

TEST_SETUP(Test01b_Init)
{
}
TEST_TEAR_DOWN(Test01b_Init)
{
}

TEST(Test01b_Init, testInitUSB)
{
}

TEST_GROUP_RUNNER(Test01b_Init)
{
 RUN_TEST_CASE(Test01b_Init, testInitUSB);
}

2) yes, they are unchecked

Yes, that works.

But there are places where the indexer is useful.  I will leave it as is, hopefully knowing which parts are broken, and wait for a fix.
