Hi, after building and installing dmd i fail to use generated
executable because they are an undefined symbol.
$ /opt/dmd/bin/dmd -L-lcurl testDelegate.d
$ ./testDelegate
./testDelegate: symbol lookup error:
/opt/dmd/lib/libphobos2.so.0.66: undefined symbol:
curl_version_info
$ ldd ./testDelegate

given executable is link with libcurl provided by dmd
when i look into these curl lib they are any curl_version_info
symbol
# readelf -Ws /opt/dmd/lib/libcurl.so.4 | grep curl_version_info
# readelf -Ws /opt/dmd/lib/libcurl_stub.so | grep
curl_version_info
while this symbol exist on libcurl provided by my fedora
# readelf -Ws /usr/lib64/libcurl.so.4| grep curl_version_info
346: 0000000000023f20 140 FUNC GLOBAL DEFAULT 11
