无法安装/制作freetds OS X Yosemite

Question

I am trying to install the gem tiny_tds on my Macbook, so I first tried to install the freetds dependency by running brew install freetds . However, it doesn't work and I get an error that makes no sense to me :

libtool: link: clang -D_THREAD_SAFE -g -O2 -I/usr/local/opt/openssl/include -Wdeclaration-after-statement -o .libs/bsqldb bsqldb.o  -L/usr/local/opt/openssl/lib ../dblib/.libs/libsybdb.dylib ../replacements/.libs/libreplacements.a -lssl -lcrypto /usr/local/Cellar/libiconv/1.13.1/lib/libiconv.dylib

I also tried to compile the freetds from the source, and I also got an error:

I do not really understand why I cannot compile freetds on my machine and I would be glad if someone helped me !

Thank you in advance.

Answer 1

I actually found a solution to my problem ! Apparently, Libiconv was installed as a dependency to another program by brew. But this installation was not compiled for my architecture so not working properly. I had to uninstall the brew version of libiconv and reinstall it manually.

brew uninstall libiconv
brew install libiconv
brew install freetds

I am not sure it is necessary to reinstall libiconv via brew as it is supposed to be part of the Mac OS now. Hope this helps people who have the same problem.
