为ndk生成配置coverity 我想用Copystatic进行静态分析,我需要C++。由于我的项目使用Android NDK,我将编译器配置为: cov-configure –comptype gcc –compiler ~/android-ndk-r8e/toolchains/arm-linux-androideabi-4.6/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc-4.6

This may be due to a problem with your configuration or because no files were actually compiled by your build command. Please make sure you have

然后我运行了
cov build–dir coverity ndk build–j8 ndk_DEBUG=1

一切都会建立起来,但我有一个警告

*[*WARNING] No files were emitted. This may be due to a problem with your configuration
or because no files were actually compiled by your build command.

所以我无视警告,跑了

那么我的编译器配置正确吗?以前有人为Android NDK配置过编译器吗?

在coverity/build-log.txt中,您应该可以看到构建过程中执行的所有命令(查看“EXECUTING:”)。仔细检查编译器命令是否与指定要配置cov的编译器匹配。您可以配置多个编译器,配置通用gcc(“cov configure--gcc”)可能很有用


请记住,如果您的ndk构建实际上没有构建任何东西,那么cov构建将给出类似的消息。换句话说,该消息并不总是表明存在问题——可能生成已完成,但实际上没有编译任何文件。

您应该为NDK配置正确的编译器:

cov-configure --comptype gcc -compiler arm-linux-androideabi-gcc --template

您向coverity指出编译器是~/android-ndk-r8e/toolschains/arm-linux-androideabi-4.6/prebuild/linux-x86_64/bin/arm-linux-androideabi-gcc-4.6

确保这是命令中正确的完整路径(可能替换“~”?),并且arm-linux-androideabi-gcc-4.6正是用于编译的

我有同样的问题,因为Coverity希望使用GCC,但我的构建使用了cc

然后我设置:

~/coverity-current/bin/cov-configure --compiler /usr/bin/cc --comptype gcc
它显示:

[WARNING] A template configuration is recommended for this compiler.
Add "--template" to your command line, or use one of the
template configuration shortcut command lines below:

  cov-configure --gcc      # GNU C/C++ compiler (gcc/g++)
  cov-configure --msvc     # Microsoft C/C++ compiler (cl)
  cov-configure --java     # Sun Java compiler (javac)

You must remove the specific configuration before re-running with "--template".

* Configuring /usr/bin/cc as a C++ compiler

cov构建命令是:

../../coverity-current/bin/cov-build --dir ~/build_cov/myapp/cov-log-all-output make -C ~/build_cov/myapp
结果是:

../../coverity-current/bin/cov-build --dir ~/build_cov/myapp/cov-log-all-output make -C ~/build_cov/myapp

[...]

76 C/C++ compilation units (100%) are ready for analysis
The cov-build utility completed successfully.

在cov log all output/c/emit/pcname/

中有一个更大的emit db文件,所以我也遇到了同样的问题并解决了它。 在我的例子中,make file是问题所在,尽管编译器配置正确,但我得到了以下警告:

没有发出任何文件。这可能是由于您的配置有问题 或者因为build命令实际上没有编译任何文件。 请确保已配置编译中实际使用的编译器


make文件包含一些我不想使用的目标。因此,如果您不确定makefile中定义的所有目标,只需删除它们并编译您需要的和知道的任何内容。否则,请与其他人讨论剩余目标。

您好,感谢您的回复。编译后,它会在libs文件夹下生成.so文件。我看到编译器命令,它是正确的。编译器的路径也是正确的。请您澄清一下ndk build不编译任何文件意味着什么。再次感谢!编译器名称很重要。有关更多详细信息,请参阅Coverity文档!
