I am trying to compile simple test program using libftdi driver for FTDI chips, but unsuccessfuly.
Part of code:

Code: Select all

/* hello-ftdi.c: flash LED connected between CTS and GND.
   This example uses the libftdi API.
   Minimal error checking; written for brevity, not durability. */
#include <stdio.h>
#include <ftdi.h>
#define LED 0x08  /* CTS (brown wire on FTDI cable) */
int main()
{........


Command and its failure:

Code: Select all

milan ~/CCPP $ gcc ftdi.c -o helloftdi
ftdi.c:6:18: fatal error: ftdi.h: File or directory does not exist
 #include <ftdi.h>
                  ^
compilation terminated.


And now little bit mismatch (for me)

Code: Select all

milan ~/CCPP $ urpmq libftdi1
Package with name libftdi1 does not exists
milan ~/CCPP $ urpmq libftdi1_2
libftdi1_2


ftdi.h located in /usr/include/libftdi1

mga5 specfile:

Code: Select all

%define api 1
%define major 2
%define libname %mklibname ftdi %{api} %{major}


1.Why must be there major2?
2.What is the solution for my program?

Thank You for answers, Milan

You're missing the package which includes the header ftdi.h, so search for that file:

What mismatch in particular?

1. because the SONAME of that library has 2 as the major version.

Code: Select all

[doktor5000@Mageia5]─[20:11:01]─[~] objdump -ap /usr/lib64/libftdi1.so.2 | grep -i soname
  SONAME               libftdi1.so.2

2. install the package with the missing header file and compile again.

1. Thank You for explaining, I didn´t know this.
2. libftdi1-devel was installed

Please mark the thread accordingly by editing the topic of the first post and prefix it by [SOLVED], thanks

Very sorry for this misunderstanding.
It was meant so that libftdi-devel was installed before compilation, so the problem persists.
The same problem I have with Pclos via Virtualbox, so I will try to find out any other solution.
Thank You
