error: ‘gflags’ has not been declared

[waitwaitwaitforME]

Hello! Thank you for your open source! And I have some problems when I built the EGSfM: In function ‘int main(int, char)’: /home//EGSfM/ext/libvot/src/examples/image_search.cpp:61:2: error: ‘gflags’ has not been declared gflags::ParseCommandLineFlags(&argc, &argv, true);

and /home//EGSfM/app/fisher_vector_similarity.cpp:101:5: error: ‘gflags’ has not been declared gflags::ParseCommandLineFlags(&argc, &argv, false); /home//EGSfM/app/fisher_vector_trainer.cpp:76:5: error: ‘gflags’ has not been declared gflags::ParseCommandLineFlags(&argc, &argv, false);

I have already installed the gflags and some paths are shown below. GFLAGS_INCLUDE_DIR:PATH=/usr/include GFLAGS_LIBRARY:FILEPATH=/usr/lib/x86_64-linux-gnu/libgflags.so // gflags namespace (google or gflags) GFLAGS_NAMESPACE:STRING=google

So could you please give me some advice on how to deal with this problem? Thank you so much!

Does the cmake find the path of gflag? Could you provide more information, as it's hard for me to reproduce this issue.

Sorry to bother you. In cmake step, the corresponding messages are as follows. -- Check for Google Log -- Found Glog: /usr/local/include
-- Found Google Logging: /usr/local/include -- Check for gflags -- Found GFlags: /usr/include ... -- Found GFlags: /usr/local/include
-- Found gflags (include: /usr/local/include, library: /usr/lib/x86_64-linux-gnu/libgflags.so) -- Found glog (include: /usr/local/include, library: /usr/local/lib/libglog.so) ... -- Found required Ceres dependency: gflags No error occured in the cmake step.
