Hello everybody, I have e-fax integration to be integrated in my application(a website which is build in PHP) where I need to install HTTP Request Module first , then should make a change in my php.ini file. For that to happen I need to execute four steps. They are : sudo yum install php-xml sudo yum install php-devel sudo pecl install pecl_http sudo yum install php-pear-HTTP-Request I am facing a problem in executing the 3rd step. The error what I am getting is building in /var/tmp/pear-build-root/pecl_http-1.6.2 running: /temp/pecl_http/configure --with-http-curl-requests --with-http-zlib-compression=all --with-http-magic-mime=all --with-http-shared-deps checking for egrep... grep -E checking for a sed that does not truncate output... //bin/sed checking for gcc... gcc checking for C compiler default output file name... configure: error: C compiler cannot create executables See `config.log' for more details. ERROR: `/temp/pecl_http/configure --with-http-curl-requests --with-http-zlib-compression=all --with-http-magic-mime=all --with-http-shared-deps' failed Please do suggest what modification should be done in order to fix this issue. Thanks & Regards Ramesh.
