Abstract

A method, apparatus and article of manufacture that implements the method, automatically identifies and reuses software libraries. In various embodiments, a first set of specified block names is received. One or more libraries of the source project which contain the blocks associated with the first set of specified block names are automatically identified to provide a first set of libraries for reuse. In some embodiments, one or more depended-upon blocks associated with the blocks of the first set of libraries are also automatically identified; and, one or more depended-upon libraries in the source project, which contain the depended-upon blocks, are automatically identified for reuse. In yet another embodiment, a reuse library is built based on static libraries of the first set of libraries and static libraries of the depended-upon libraries.

Claims

1. A method of reusing software from a source project, comprising:

receiving a first set of specified block names; and

automatically identifying one or more libraries in the source project which contain blocks having the specified block names to provide a first set of libraries for reuse.

2. The method of claim 1 further comprising:

automatically identifying one or more depended-upon block names associated with the blocks of the first set of libraries; and

automatically identifying one or more depended-upon libraries, in the source project, which contain blocks having the one or more depended-upon block names for reuse.

3. The method of claim 2 further comprising:

building a reuse library comprising static libraries of the first set of libraries and any depended-upon static libraries of the one or more depended-upon libraries.

4. The method of claim 3 further comprising:

generating a wrapper library comprising wrappers for the specified block names and the reuse library; and

building a target project based on the wrapper library.

5. The method of claim 4 further comprising:

creating wrapper source code to generate the wrapper library comprising a wrapper function for each of the specified block names, wherein said generating generates the wrapper library, at least in part, based on the wrapper source code, the reuse library and reuse-header files.

6. The method of claim 3 further comprising:

generating a library-builder file to build the reuse library.

7. The method of claim 3 further comprising:

building an executable target software project based on, at least in part, the reuse library.

8. The method of claim 7 further comprising:

when said building of the executable target software project has an unresolved reference error, the unresolved reference having a name, supplying the name of the unresolved reference as a specified block name, and repeating said receiving, automatically identifying one or more libraries, automatically identifying one or more depended-upon block names and automatically identifying one or more depended-upon libraries, to provide one or more additional libraries associated with the name of the unresolved reference.

9. The method of claim 8 further comprising:

rebuilding the reuse library with the one or more additional libraries; and

repeating said building of the executable target software project.

10. The method of claim 1 wherein said receiving further comprises:

generating a graphical user interface comprising a list of the names of the blocks of the first set of libraries; and

selecting from the list of the names of the blocks to provide at least one block name of the first set of specified block names.

11. The method of claim 1 further comprising:

specifying at least one block name via a graphical user interface to provide the first set of specified block names; and

displaying the names of the libraries of the first set of libraries on the graphical user interface.

12. The method of claim 10 further comprising:

in response to a user activation, generating a wrapper for the at least one block name of the first set of specified block names.

13. An apparatus for reusing software from a source project, comprising:

a processor; and

a memory storing one or more instructions that;

receive a first set of specified block names; and

automatically identify one or more libraries in the source project which contain blocks having the specified block names to provide a first set of libraries for reuse.

14. The apparatus of claim 13 wherein said one or more instructions further comprise instructions that:

automatically identify one or more depended-upon block names associated with the blocks of the first set of libraries; and

automatically identify one or more depended-upon libraries, in the source project, which contain blocks having the one or more depended-upon block names for reuse.

15. The apparatus of claim 14 wherein said one or more instructions further comprise instructions that:

build a reuse library comprising static libraries of the first set of libraries and any depended-upon static libraries of the one or more depended-upon libraries.

16. The apparatus of claim 15 wherein said one or more instructions further comprise instructions that:

generate a wrapper library comprising wrapper blocks for the specified block names.

17. An article of manufacture comprising a computer program usable medium embodying one or more instructions executable by a computer for performing a method of reusing software from a source project, said method comprising:

receiving a first set of specified block names; and

automatically identifying one or more libraries in the source project which contain blocks having the specified block names to provide a first set of libraries for reuse.

18. The article of manufacture of claim 17 wherein said method further comprises:

automatically identifying one or more depended-upon block names associated with the blocks of the first set of libraries; and

automatically identifying one or more depended-upon libraries, in the source project, which contain blocks having the one or more depended-upon blocks for reuse.

19. The article of manufacture of claim 18 wherein said method further comprises:

building a reuse library comprising static libraries of the first set of libraries and any depended-upon static libraries of the one or more depended-upon libraries.

20. The article of manufacture of claim 19 wherein said method further comprises:

generating a wrapper library comprising wrappers for the specified block names and the reuse library; and

building a target project based on the wrapper library.

21. The article of manufacture of claim 20 wherein said method further comprises:

creating wrapper source code to generate the wrapper library comprising a wrapper block for each of the specified block names;

wherein said generating generates the wrapper library, at least in part, based on the wrapper source code, the reuse library and reuse header files.

22. The article of manufacture of claim 19 wherein said method further comprises:

generating a library-builder file to build the reuse library.

23. The article of manufacture of claim 19 wherein said method further comprises:

building an executable target software project based on, at least in part, the reuse library.

24. The article of manufacture of claim 23 wherein said method further comprises:

when said building of the executable target software project has an unresolved reference error, supplying a name of the unresolved reference as a specified block name, and repeating said receiving, automatically identifying one or more libraries, automatically identifying one or more depended-upon block names, and automatically identifying one or more depended-upon libraries, to provide one or more additional libraries associated with the name of the unresolved reference.

25. The article of manufacture of claim 24 wherein said method further comprises:

rebuilding the reuse library with the one or more additional libraries; and

repeating said building of the executable target software project.

26. The article of manufacture of claim 17 wherein said receiving further comprises:

generating a graphical user interface comprising a list of the names of the blocks of the first set of libraries; and

selecting from the list of the names of the blocks to provide at least one block name of the first set of specified block names.

27. The article of manufacture of claim 17 wherein said method further comprises:

specifying at least one block name via a graphical user interface to provide the first set of specified block names; and

displaying the names of the libraries of the first set of libraries on the graphical user interface.
