Ethereum Development in Debian -based linux: surpassing errors with db_cxx.h

. A common problem found by many developers is finding errors related to the lack of header files, specifically db_cxx.h. In the causes of these errors and provide guidance on how to overcome them by creating Ethereum on Linux, based on Debian.

** Why do I get the «no such file or directory» error?

The error message «Headers.h: 36: 20: Fatal error: db_cxx.h: No file or directory» indicates that the compiler cannot find the header’s header file db_cxx.h. This file is part of the Ethereum C ++ libraries, which are used by the Ethereum development team. The facilities are installed on your system.

Installing the necessary packages

Linux, based in Debian, you will need to install multiple packages:

• Libdb4 (a PostgreSQL database library)

2.

3.

Using your package manager:

`Bash

SUDO APT-GET INSTALL LIBDB4-DEV DBCPP

`

Overcoming errors with missing header files

The facilities are installed and configured correctly. Here is a step by step guide:

• Reinstale Libdb4

  :

`Bash

SUDO APT-GET REMOVE LIBDB4-*

`

• Follow the installation instructions to install DBCPPPPPPP.

. You

Bash

-Std = c ++ 11 -wall -g -g -i/USR/Include/PostgreSQL/10 -L/USR/LIB/PostgreSQL/10 -LDBC

`

Replace /USR/Include/PostgreSQL/10 E/USR/LIB/PostgreSQL/10 By the real paths of your system.

• Reconstructs Ethereum

  : After updating the compiler settings, rebuild the Ethereum using:

`Bash

Make clean && to do

`

This should solve any problems related to the lack of header files.

Troubleshooting

Ethereum or execution tests, make sure:

• Your system is updated with the latest packages.

• Dependencies LIBDB4 EDBCPPP are installed correctly.

• You updated the compiler settings according to the above instructions.

• You rebuilt Ethereum using the correct commands.

«Headers.H: 36: 20: Fatal error: db_cxx.h: no file or directory» Error and build successfully and run Ethereum on your Linux system based on Debian.
