Can not find `eosio/eosio.hpp` while compiling with eosio-cpp

[arvindkalra]

I used the documentation provided by EOSI. I made all the required installation as suggested in the docs. While writing the hello world contract, I face this issue when running the following command eosio-cpp -abigen -o hello.wasm hello.cpp. Please help. I am using Ubuntu 18.04 Machine (As I saw in some posts that this error is machine specific)

hello.cpp:1:10: fatal error: 'eosio/eosio.hpp' file not found
#include <eosio/eosio.hpp>
         ^~~~~~~~~~~~~~~~~
1 error generated.

Can you provide which version of eosio-cpp you are currently using?

Example:

~ $ eosio-cpp --version
eosio-cpp version 1.6.1

---

Also, what is in your /usr/local/eosio.cdt/include/eosiolib/contracts/eosio/ directory?

Example:

/usr/local/eosio.cdt/include/eosiolib/contracts/eosio $ ls
action.hpp    dispatcher.hpp  multi_index.hpp  privileged.hpp         singleton.hpp  transaction.hpp
contract.hpp  eosio.hpp       permission.hpp   producer_schedule.hpp  system.hpp

I've just upgraded to 1.6.1 from 1.5.0 and now can't compile anything. on OSX the directory you refer to is /usr/local/Cellar/eosio.cdt/1.6.1/opt/eosio.cdt/include/eosiolib/contracts/eosio/ and mine contains:

-rw-r--r--  1 ekkis  staff  21043 Mar 22 16:03 action.hpp
-rw-r--r--  1 ekkis  staff   2672 Mar 22 16:03 contract.hpp

-rw-r--r--  1 ekkis  staff  10273 Mar 22 16:03 transaction.hpp

but I'm also getting all these other errors:

Error while trying to load a compilation database:
Could not auto-detect compilation database for file "token.cpp"

fixed-compilation-database: Error while opening fixed database: No such file or directory

there is no guidance on the release notes about initialising databases nor have I been able to find info by googling the errors. any help would be much appreciated

eosio-cpp still fails (CDT 1.7.0) with the same error reported by the OP in some situations like when -E (Only run the preprocessor) is used/specified. e.g. Is not possible to use Makefile targets ended in .i. Even when using eosio-cpp by hand, with all the include directories specified, the error appears:

CDT installation (binaries and source code)

$ wget https://github.com/eosio/eosio.cdt/releases/download/v1.7.0/eosio.cdt_1.7.0-1-ubuntu-18.04_amd64.deb
$ sudo apt install ./eosio.cdt_1.7.0-1-ubuntu-18.04_amd64.deb
$ git clone https://github.com/EOSIO/eosio.cdt.git
$ cd eosio.cdt
$ git checkout v1.7.0

Example 1: Using the generated Makefile

$ cd eosio.cdt/examples/hello/
$ mkdir build
$ cd build
$ cmake ..
$ make  # << This works Ok, but the following doesn't
$ cd tests
$ make hello_test.i
eosio.cdt/examples/hello/tests/hello_test.cpp:1:10: fatal error: 'eosio/eosio.hpp' file not found
#include <eosio/eosio.hpp>

Hi,

I am trying to complete the EOSIO tutorial for helloworld on Ubuntu 20.04 and I keep getting an error when trying to compile because I cannot #include the eosio.hpp file.

I don't think this issue has been resolved, can someone help me?

why are you even trying to build on EOS? I've abandoned it as it offers zero support to developers

[wfalcon3]

@ekkis just trying to learn, might eventually develop for Telos which runs EOS.io

any help on the question though? why can't my compiler locate the eosio.hpp?

[ekkis]

try:

#include <eosio/eosio.hpp>

but seriously... don't waste your time. build on Polkadot or Cosmos or something that isn't a badly managed island

I don't know how are you trying to compile or install EOS blockchain or CDT. If you don't want to deal with that, you can use my development docker which includes a blockchain node (v2.0.6) as well as CDT (v1.7.0). The OP's example (https://developers.eos.io/eosio-home/docs/your-first-contract) works OK with it. The docker also includes tools like Vim and Midnight Commander.

In order to start with coding, first install docker, and 2nd do the following in a terminal:

$ docker run -it jalbiero/eosdev bash

After that, follow the given instructions in the aforementioned example.

If you want to know how to compile/install EOS and CDT you can see the docker build project here: https://github.com/jalbiero/eos-dev-docker

I will be updating the docker image soon with the latest versions of EOS and CDT.

FYI:

I updated the docker image to EOS 2.0.10: https://hub.docker.com/r/jalbiero/eosdev

I also added some examples that show how to use the docker: https://github.com/jalbiero/eos-dev-docker/tree/master/samples

@wfalcon3 One thing that I forgot to mention: Current official releases (2.0.x) don't support Ubuntu 20.04. You have to wait for EOS 2.1.x (currently 2.1.0-rc3).
