C2065 'idx': undeclared identifier (compiling source file fastcluster.cpp)

[madinwei]

Hello, @cdalitz ,
Thank you for this awesome repository,
I am trying to use fastcluster.cpp in my application, I followed your instruction and copied fastcluster_dm.cpp, fastcluster_R_dm.cpp, and copied and compile fastcluster.[h|cpp].

however, this error appears,

C2065	'idx': undeclared identifier (compiling source file fastcluster.cpp)	d:\demo_07-11\infraredmonitor\software\c&c++\infraredmonitor\infraredmonitorserver\fastcluster_dm.cpp	830	

I am using visual studio 2017 on Win 10, I hope you can provide any solution or advice .

The data type t_index is defined in line 138 of fastcluster_dm.cpp as follows:

typedef int_fast32_t t_index;

Is int_fast32_t not found? Maybe it is in some special namespace, e.g. std::int_fast32_t? Please check this and let me know, so that I can change this appropriately.

@cdalitz , thank you for your response and help.

The data type t_index is defined in line 138 of fastcluster_dm.cpp as follows:

typedef int_fast32_t t_index;

I found it defined in line 130

Is int_fast32_t not found? Maybe it is in some special namespace, e.g. std::int_fast32_t? Please check this and let me know, so that I can change this appropriately.

I also used std::int_fast32_t , but still has that error. however, now there is another error as shown in this screenshot:

The sample project includes a file CMakeLists.txt. Please use this file to create a VisualStudio project and see whether you can compile this project. If you can, there must be something wrong with your own project.
