Installing PECL on MAMP
Wait wait wait wait. Why are you rebuilding your PHP installation to install the MongoDB driver?
You don't have to do that.
Just run e.g.:
/Applications/MAMP/bin/php/php7.1.1/bin/pecl install mongoAssuming thats the full path to the pecl command part of your MAMP installation.
You might need to replace /php7.1.1/ with your current and active MAMP php version.
Working on this right now and found a workaround to just disable iconv with ./configure --without-iconv which not the best solution of course, but works for me.
Edit: Downloaded libiconv-1.14 package, and after running ./configure , make, make install, PHP configure runs fine.
This did it for me:
$ ./configure --with-iconv=/usr/lib/First needed to install libxml2 and libxslt via homebrew though:
$ brew install libxml2$ brew install libxslt
