Failing to compile libosmium: 'protozero/types.hpp' file not found

[Selina22]

Hi, I'm using the latest version of libosmium and protozero, and am currently trying to set up everything. I tried to run osmium_read.cpp under the examples directory and receive the error:

In file included from osmium_read.cpp:19:
In file included from /usr/local/include/osmium/io/any_input.hpp:48:
In file included from /usr/local/include/osmium/io/o5m_input.hpp:42:
/usr/local/include/osmium/io/detail/o5m_input_format.hpp:56:10: fatal error: 'protozero/exception.hpp' file not found
#include <protozero/exception.hpp>
         ^~~~~~~~~~~~~~~~~~~~~~~~~
1 error generated.

I followed through the guide and set up everything properly. I also saw this ticket here (osmcode/osmium-tool#127) and manually edited the protozero include path, but I still get this error. How can I resolve this issue?

Looks like there is an error somewhere in what you did but from your vague description ("latest version of libosmium and protozero", "set up everything properly", "manually edited the protozero include path") we can't figure out what that is. Show us all the commands you used and their output. Maybe we can figure it out then.

I cloned the latest version of libosmium and protozero from GitHub, and they are saved in the same directory. Then in the libosmium directory, I created the build directory and ran cmake .. and make within, and here is the output result from ccmake .. under the build directory:

After that, I compiled the script under examples (g++ examples/osmium_read.cpp -std=c++11) and got the file not found error; however, I did clone protozero and the PROTOZERO_INCLUDE_DIR is correct.

That's pretty much all the steps I took just to try running osmium_read.cpp under the examples directory. Here is the version of GCC and Clang that I have:

Configured with: --prefix=/Library/Developer/CommandLineTools/usr --with-gxx-include-dir=/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/c++/4.2.1
Apple clang version 12.0.0 (clang-1200.0.32.29)
Target: x86_64-apple-darwin20.2.0
Thread model: posix
InstalledDir: /Library/Developer/CommandLineTools/usr/bin

I'm not sure where I messed up, and I hope that's enough information.

You can't just compile a program using g++ examples/osmium_read.cpp -std=c++11, because that way it will not use the configuration you created with cmake. Simply call make in your build directory to compily everything. Or, if you only want to compile one part of the whole thing, use that as parameter to make: make osmium_read in this case.

Ok I see. That works for me now, thanks!

Now, I still have the same file not found problem when I try to create my own project using osmium. I simply just inserted #include <osmium/io/any_input.hpp> in one of my .hpp files just to make sure everything is set up properly. I downloaded FindOsmium.cmake and FindProtozero.cmake and saved them to the project cmake directory. Here is my ccmake output:

When I compiled with make, I still got the file not found error:

Sorry, this isn't a C++ help line, but a bug tracker for Osmium. Help on how to set up your own CMake configuration is waay beyond what we can provide here.
