Re: [platform-core-dev] Problem with environment variables and link path

[John Arthorne <John_Arthorne@xxxxxxxxxx>]

This is the platform core mailing list,
which has nothing to do with CDT. I suggest trying the eclipse.tools.cdt
newsgroup.

Subject	[platform-core-dev] Problem with environment variables and link        paths during build

Hi,

I am developing on Eclipse Europa 3.3 and CDT 4.0

We are extending CDT Functionalities and doing some customizations.

We have a plugin which extends the buildDefinitions providing new project
type and project nature and defining our own tool chain.

To integrate this toolchain we have defined our own Configuration Level
Environment Provider.

We are extending for this reason IBuildEnvironmentVariable which extends
IEnvironmentVariable.

For operation we use the value : IBuildEnviornmentVariable.ENVVAR_REPLACE.
For delimeter we use the value : null.

However I realized that for default OS set enviornment variables , if we
invoke Eclipse from this it works fine.

Now if we set few environment variables before invoking Eclipse and then
invoke it gets complete new and added list of environment variables, but
in
this case it is failing at linking. The link paths got screwed up and is
showing : in place of -L.

For Eg :

ppcnf-linux-g++:
:/home/nayna/workspace/runtime-EclipseApplication/Test1/export/abc/xyz/lib:/esw/test/Builds/btest/export/abc/xyz/lib:
 No such file or directory


I tried the same thing with delimeter="" ; or delimeter="
";
In this case it works fine and the extra command doesn't appear. I was
suprised that it worked fine for some random value also like delimeter="@".

I would like to know the exact purpose of delimeter and where is it used
?
On what basis should we decide its value ?

I tried going through CDT code using debugger but couldn't understand
enough . Also from the Build Macros and BuildEnvironmentVariables I
couldn't get much information.

Also , I would like to know how  and where does this linker paths
are
constructed

So, please let me know if someone can help.

Thanks & Regards,
Nayna Jain
