C++ Compilation problem on Linux

[sunny...@gmail.com]

Hi,

I need a help regarding comiplation of a cprogramme on linux machine.

When I log on linux machine with my userID and then switch to
superuser with " su" commands , it compiles perfectly. But when I
switch to superuser with "su -" command, It gives hell lot of errors.
It starts somthing like

"<command line>:1:1: macro names must be identifiers " .

I verified all include path and other enviornment variables , all the
exactly same.

Could anyone plz suggest what might be the cause of the problem ?

Thanks in advance.

Sunny,

Is the LD_LIBRARY_PATH same when you do su and su - ??

LD_LIBRARY_PATH comes into pictuer while executing that binary not at the compile time . isn't it ?

Its not necessary. You may also need this while compiling, in case you
are using any methods etc from other libraries. So you may need to
give the LD_LIBRARY_PATH to get reference to those libraries.
