error: missing fdtdi1 library

[markmitton]

I am unable to configure and build this library. The ./configure script complains that the libftdi1 library is missing but ldconfig reports the loaded library. I built and installed the FTDI library from here http://developer.intra2net.com/libftdi

error: missing libftdi1 library
root@iot2000:/opt/libmpsse/src# ldconfig -p | grep ftdi1
libftdi1.so.2 (libc6) => /usr/local/lib/libftdi1.so.2
libftdi1.so (libc6) => /usr/local/lib/libftdi1.so

Any thoughts as to what I could do to get the ./configure script to correctly detect the library?

Thanks

Have you tried building https://github.com/l29ah/libmpsse
?

Hi I29ah,

Thanks, I did and get the same result:

configure: error: missing libftdi library

libftdi1.so.2 (libc6) => /usr/local/lib/libftdi1.so.2

Do you know if the configure script uses a different mechanism to check if the library is installed/usable?

Thanks
