Executing the .so file in libftdi

I am using the ft232r library provided by ftdi to program the LPC11C14 microcontroller via Linux Mint. To initialize the software, I need to run the following command:

./ft232r_prog --manufacturer Sunswift --product $(PROJECT_NAME) --invert_rts --invert_dtr

When I run the code, I have the following problem:

Error while loading shared libraries: libftdi.so.1: cannot open shared object file: No such file or directory

when running ldd ft232r_prog, I get:

linux-gate.so.1 =>  (0xf77b8000)
libusb-0.1.so.4 => /lib/i386-linux-gnu/libusb-0.1.so.4 (0xf7790000)
libftdi.so.1 => not found
libc.so.6 => /lib/i386-linux-gnu/libc.so.6 (0xf75e5000)
/lib/ld-linux.so.2 (0xf77b9000)

The file libftdi.so.1

is located in /usr/lib/x86_64-linux-gnu

. Since the executable ft232r_prog cannot find the .so file, I tried the following:

  • Updated path environment variable to locate / usr / lib / x 86_64-linux-gnu - Failed
  • Updated $ LD_LIBRARY_PATH environment variable to contain /usr/lib/x86_64-linux-gnu

    - Failed
  • Ran ldconfig

    in /usr/lib/x86_64-linux-gnu

    - crash

This appears to be a common problem including shared libraries. Any ideas on how I can solve this?

I suspect your system is 64-bit and your program is 32-bit. In this case, you need to install the 32-bit version of the library.

To install 32-bit libftdi on Ubuntu 12.04 x64, follow these steps:



$ sudo apt-get install libftdi1:i386
