Build Identifier: Eclipse IDE for C/C++ Developers, Version: Helios Service Release 1, Build id: 20100917-0705, with PTP 4.0.3

I have created a new Fortran static library project then imported a Fortran code that contains about 250 files.  I have determined that during the Make process, not the actual compile step, I get an error of "Too many open files".  I have determined the number of opened files by "while true; do lsof | grep java | wc -l; done".  From more experienced personnel who use Eclipse, this error does not occur with a C/C++ project of even larger size. 

Error Window
------------
Problems occurred building the selected resources.
Errors running builder 'CDT Builder' on project 'X'.
Could not write file: /home/.../workspace/X/Debug/makefile.
/home/.../workspace/X/Debug/makefile (Too many open files)
