"""fuse_gtest_files.py v0.2.0
|
|
Fuses Google Test source code into a .h file and a .cc file.
|
|
|
|
SYNOPSIS
|
|
fuse_gtest_files.py [GTEST_ROOT_DIR] OUTPUT_DIR
|
|
|
|
Scans GTEST_ROOT_DIR for Google Test source code, and generates
|
|
two files: OUTPUT_DIR/gtest/gtest.h and OUTPUT_DIR/gtest/gtest-all.cc.
|
|
Then you can build your tests by adding OUTPUT_DIR to the include
|
|
search path and linking with OUTPUT_DIR/gtest/gtest-all.cc. These
|
|
two files contain everything you need to use Google Test. Hence
|
|
you can "install" Google Test by copying them to wherever you want.
|
|
|
|
GTEST_ROOT_DIR can be omitted and defaults to the parent
|
|
directory of the directory holding this script.
|
|
|
|
EXAMPLES
|
|
./fuse_gtest_files.py fused_gtest
|
|
./fuse_gtest_files.py path/to/unpacked/gtest fused_gtest
|
|
|
|
This tool is experimental. In particular, it assumes that there is no
|
|
conditional inclusion of Google Test headers. Please report any
|
|
problems to googletestframework@googlegroups.com. You can read
|
|
http://code.google.com/p/googletest/wiki/GoogleTestAdvancedGuide for
|
|
more information.
