I am trying to compile Erlang OTP-R16B03-1 on FreeBSD 10.1 OS. When i run the ./configure command the output is 

odbc           : ODBC library - header check failed

I have tried installing unixODBC, iODBC. Also /usr/ports/databases/unixODBC exists. The sql.h file is located in /usr/local/include.

I am still getting the link failed error. Any help will be useful

The log for ./configure |grep odbc command is as shown below

config.status: WARNING:  'Makefile.in' seems to ignore the --datarootdir setting
=== configuring in odbc/. (/root/otp_src_R16B03-1/lib/odbc/.)

  • Check `lib/odbc/config.log` for more detailed error messages. Also, [this question](http://stackoverflow.com/q/19149714/113848) might help. – legoscia Apr 19 '17 at 09:20

I had the same problem on erlang 21 but when I downloaded the newest version from github (erlang 22), and tried ./configure the error ODBC library - header check failed appeared again but after trying make install again, everything finished successfully.

What finally worked for me was

apt-get install unixodbc-dev

Then

 otp_build configure --with-odbc=/usr/lib/x86_64-linux-gnu/
