Abstract

The disclosed embodiments provide a system that facilitates the development and compilation of a software program. During operation, the system obtains a set of compilation units to be used in the software program and a version order associated with a programming language of the compilation units. Next, for each compilation unit from the set of compilation units, the system uses the version order to select a version of the programming language that is compatible with the compilation unit. The system then uses the version to compile the compilation unit.

First claim

What is claimed is:

1. A method, comprising:
at a computer system, obtaining:
a set of source code modules to be used in a software program; and
an ordering between one or more older versions of a programming language and one or more newer versions of the programming language, wherein one or more versions of the programming language are to be used while compiling the source code modules; and

for each source code module from the set of source code modules:
selecting a version of the programming language from a set of versions of the programming language by using the ordering, wherein the selected version of the programming language is compatible with the source code module, and wherein the selecting the version of the programming language that is compatible with the source code module involves:
attempting to compile the source code module using a first version of the programming language in the ordering,
responsive to the source code module compiling successfully with the first version of the programming language, selecting the first version of the programming language, and
responsive to the source code module not compiling successfully with the first version of the programming language, attempting to compile the source code module using a second version of the programming language following the first version of the programming language in the ordering; and
compiling the source code module with the selected version of the programming language.

2. The method of claim 1 , further comprising:
obtaining a range of versions of the programming language with which the set of source code modules may be compiled; and
selecting the version of the programming language from the range of versions of the programming language.

3. The method of claim 2 , wherein the range of versions of the programming language specifies an oldest version of the programming language and a newest version of the programming language.

4. The method of claim 1 , wherein the ordering comprises at least one of an ascending order, a descending order, and a user-specified order.

5. The method of claim 1 , wherein the second version of the programming language is selected if the source code module compiles successfully with the second version of the programming language.

6. The method of claim 5 , wherein the second version of the programming language is selected only if other source code modules in the set of source code modules also compile successfully with the second version of the programming language.

7. The method of claim 6 , wherein the set of source code modules corresponds to at least one of a package, and a code base for the software program.

8. The method of claim 1 , wherein:
a first source code module of the set of source code modules is compiled with the first version of the programming language in the ordering and a second source code module of the set of source code modules is compiled with the second version of the programming language in the ordering; and
the first source code module is linked to a first library for the first version of the programming language in the ordering and the second source code module is linked to a second library for the second version of the programming language in the ordering.

9. A system, comprising:
a processor;
a memory;
a software development kit (SDK) configured to facilitate creation of a set of source code modules to be used in a software program; and
a compilation manager configured to:
obtain an ordering between one or more older versions of a programming language and one or more newer versions of the programming language, wherein one or more versions of the programming language are to be used while compiling the source code modules; and
for each source code module from the set of source code modules:
select a version of the programming language from a set of versions of the programming language by using the ordering, wherein the selected version of the programming language is compatible with the source code module, and wherein the selecting of the version of the programming language that is compatible with the source code module further involves:
 attempting to compile the source code module using a first version of the programming language in the ordering, responsive to the source code module compiling successfully with the first version of the programming language, selecting the first version of the programming language, and
 responsive to the source code module not compiling successfully with the first version of the programming language, attempting to compile the source code module using a second version of the programming language following the first version of the programming language in the ordering; and
 compile the source code module with the selected version of the programming language.

10. The system of claim 9 , wherein the compilation manager is further configured to:
obtain a range of versions of the programming language with which the set of source code modules may be compiled; and
select the version of the programming language from the range of versions of the programming language.

11. The system of claim 9 , wherein the ordering comprises at least one of an ascending order, a descending order, and a user-specified order.

12. The system of claim 9 , wherein the second version of the programming language is selected if the source code module compiles successfully with the second version of the programming language.

13. The system of claim 12 , wherein the second version of the programming language is selected only if other source code modules in the set of source code modules also compile successfully with the second version of the programming language.

14. The system of claim 13 , wherein the set of source code modules corresponds to at least one of a package, and a code base for the software program.

15. One or more non-transitory computer-readable storage media storing instructions that when executed by a computer cause the computer to perform a method comprising:
obtaining a set of source code modules to be used in a software program and an ordering between older versions of a programming language and newer versions of the programming language, wherein one or more versions of the programming language are to be used while compiling the source code modules; and
for each source code module from the set of source code modules:
selecting a version of the programming language from a set of versions of the programming language by using the ordering, wherein the selected version of the programming language is compatible with the source code module, and wherein the selecting the version of the programming language that is compatible with the source code module further involves:
attempting to compile the source code module using a first version of the programming language in the ordering, responsive to the source code module compiling successfully with the first version of the programming language, selecting the first version of the programming language, and
responsive to the source code module not compiling successfully with the first version of the programming language, attempting to compile the source code module using a second version of the programming language following the first version of the programming language in the ordering; and
compiling the source code module with the selected version of the programming language.

16. The one or more non-transitory computer-readable storage media of claim 15 , the method further comprising:
obtaining a range of versions of the programming language with which the set of source code
