Dear Sir or Madam, My name is Yev Gurevich and I head the CORE Technologies division at OPNET Technologies, Inc. (www.opnet.com). The next major release of our Modeler product will include a capability to checkpoint and restart discrete-event simulations, built upon your implementation of Checkpoint/Restart. We intend to ship LGPL-licensed libraries with our commercial product, and direct end users to download and install the GPL-licensed components. As part of our development and QA work, we have run across a particularly difficult problem -- it is not possible to attach GDB to a restarted process for the purposes of source-level debugging of that process. Specifically, GDB is unable to locate symbols when it attaches to the restarted process, and is unable to load shared libraries that were used by the restarted process. I would like to know if you would be interested in having OPNET sponsor implementation work to investigate and solve the above mentioned problem. The work in question would be funded by OPNET and returned to the open-source community by allowing you to keep the funded enhancements as part of the existing LGPL-licensed BLCR software. Please let me know if you would be interested in further pursuing this idea. If the general idea of sponsored/funded work on BLCR is acceptable but the specific feature/investigation poses particular problems, please let me know as well, so that we can consider making similar requests in the future besides the GDB-attach issue which is of particular interest to us at this time. Sincerely, Yev Gurevich ------------------------------------------------- Yev Gurevich ygurevich_at_opnet_dot_com Senior Vice President, Phone (240)-497-3000 Core Technologies Division Fax (240)-497-1064 OPNET Technologies, Inc. http://www.opnet.com -------------------------------------------------
