Error in compiling libcurl application for arm - linux

Question

i am trying to compile libcurl for arm (am-1808), the compilation works fine but when i try to build an application using libcurl, i got some errors, here are the steps i followed:
1.
./configure --host=arm-none-linux --build=i686-linux CFLAGS='-Os' --disable-ftp --disable-tftp --disable-ldap --disable-telnet --disable-dict --disable-ipv6 --disable-ares --disable-sspi --disable-cookies --disable-crypto-auth --without-libidn --without-ssl --without-zlib --without-libssh2 --without-gnutls --without-nss --without-ca-bundle --enable-smtp
2.
make
3.
sudo make install
Everything works fine up-to this step, but now on compiling a sample application i got these errors:

May be i did something wrong in the configuration while setting ./configure, any idea how can i get rid of these errors ?

Answer 1

There was problem in the configuration option, --host option was not correct, the correct argument for --host is arm-none-linux-gnueabi
so the correct configure command is (SSL should preferably be enabled).
./configure --host=arm-none-linux-gnueabi --build=i686-linux CFLAGS='-Os' --disable-ftp --disable-tftp --disable-ldap --disable-telnet --disable-dict --disable-ipv6 --disable-ares --disable-sspi --disable-cookies --disable-crypto-auth --without-libidn --without-zlib --without-libssh2 --without-gnutls --without-nss --without-ca-bundle --with-ssl=PATH --enable-smtp
NOTE:
Give path to OpenSSL in place of PATH in --with-ssl
