So I followed the Ubuntu instructions on the Datastax website to build the c++ driver (http://datastax.github.io/cpp-driver/topics/building/).
sudo apt-add-repository ppa:linuxjedi/ppa
sudo apt-get update
sudo apt-get install g++ make cmake libuv-dev libssl-dev
git clone https://github.com/datastax/cpp-driver.git
mkdir cpp-driver/build
cd cpp-driver/build
cmake ..
make
When I try to compile using g++ I get the following error messages:
test.cpp:(.text+0x11): undefined reference to cass_cluster_new'

What am I missing when trying to compile: g++ test.cpp
Thank you.
You need to actually link to the previously build cassandra driver.
g++ test.cpp -Lcpp-build/build -lcassandra
-L tells g++ where it searches for libraries
-l links the library

I have some project done on C++ and I need to compile it for Windows XP and later.
This is the header file of my RsaEncryptor class (I think it is no matter to post sources here, because I'm sure on 100% that it works fine, but if it is required I can do it):
#ifndef RSAENCRYPTOR_H_
#define RSAENCRYPTOR_H_
#include <stdexcept>
#include <openssl/rsa.h>
#include <openssl/engine.h>
#include <openssl/pem.h>
// One of this paddings can be used
//#define PADDING RSA_PKCS1_OAEP_PADDING
#define PADDING RSA_PKCS1_PADDING
//#define PADDING RSA_NO_PADDING
class RsaEncryptor {
private:
RSA* publicKey;
RSA* privateKey;
public:
RsaEncryptor() {
publicKey = nullptr;
privateKey = nullptr;
}
~RsaEncryptor() {
if ( this->publicKey )
RSA_free( this->publicKey );
if ( this->privateKey )
RSA_free( this->privateKey );
}
size_t GetCipherBytesCount() {
return 172; //is default for 1024 bit key length
}
void SetPublicKeyFromString(const std::string& content);
void SetPrivateKeyFromString(const std::string& content);

std::string Decrypt(const std::string& cipherData);
};
#endif /* RSAENCRYPTOR_H_ */
I use latest version of Eclipse Neon for C++ development on Windows 10 x64 machine.
Also I have read this:
(...) you will need to configure with no-async when building OpenSSL 1.1.0 and above for Windows XP or Vista
And I was guided by following instructions.
What did I do:
install Ubuntu 17.04 x64 inside Virtual Box under Windows 10 x64.
download latest version of OpenSSL library from Ubuntu
install mxe and all requirements (but can't compile with it and I decide to use mingw32)
install mingw32 via root#user-pc:/home/user# apt-get install gcc-mingw-w64-i686
unpack OpenSSL library in /home/user/openssl-x32
go to /home/user/openssl-x32
run ./Configure mingw --cross-compile-prefix=i686-w64-mingw32 --prefix=/home/user/builds/openssl-x32-static no-shared no-async
run make
run make install
copy libssl.a and libcrypto.a from /home/user/builds/openssl-x32-static/lib to host machine (Windows 10 x64) to folder E:\MyProjects\my-app\libraries\
copy include directory from Ubuntu to host machine in folder E:\MyProjects\my-app\include
Add libraries folder to linker configurations
Add include folder to compiler configurations
Then, I build my project and got following answer:
11:58:09 **** Rebuild of configuration Debug for project app ****

I need just link my completed C++ project with correct-compiled (with flag no-async) OpenSSL library to let it work under old versions of Windows.
I will be happy to get any help with this issue.
Most if not all of the undefined symbols in your error log come from Winsock. Try linking with -lws2_32.
I am trying to link libevent using g++ but am having trouble since I set libevent's install directory with the --prefix flag when configuring. To install libevent I downloaded the latest source, extracted it and ran the following commands in the directory
./configure --prefix=/home/tom/local --disable-shared && make
make install
After running these commands libevent successfully installs to the /home/tom/local folder. Now to test that I can use libevent I have downloaded the sample rot13 server with libevent that can be found towards the bottom of: http://www.wangafu.net/~nickm/libevent-book/01_intro.html
To compile I run the following command:
g++ -I=/home/tom/local/include rot13server.cpp -L/home/tom/local/lib
But I get the following compilation errors:
/tmp/cctwJY4k.o: In function `alloc_fd_state(event_base*, int)':

It seems like the compiler is finding the include files but not the object files.
I also tried configuring libevent without the --disable-shared option and then exported /home/tom/local/lib to the LD_LIBRARY_PATH but I still get the same error with the compile command:
g++ -I=/home/tom/local/include rot13server.cpp
Can anyone tell me what I am doing wrong?
Thanks
Can anyone tell me what I am doing wrong?
Just about everything.
The -I=/home/tom/local/include tells GCC to look in =/home/tom/local/include directory, which is unlikely to exist.
You want:
g++ -I/home/tom/local/include rot13server.cpp -c
g++ -L/home/tom/local/lib rot13server.o -levent -o rot13server

I am trying to compile and run cyrus-imapd-2.4.17-caldav-beta9.
This project has a file called configure which creates the makefile.
When I run the makefile I get errors "undefined reference to...".
One of these references is lost libical which I have installed.
In fact I have installed:
apt-get install libdb-dev
apt-get install libsasl2-dev
apt-get install libsnmp-dev
apt-get install libxml2-dev
apt-get install libical-dev
apt-get install libsqlite3-dev
I generate makefile as follow:
CFLAGS=-I/usr/include/libxml2 ./configure --enable-murder
Run the makefile as follows:

http_caldav.c:(.text+0x4210): undefined reference to `icaltime_from_string'
http_caldav.c:(.text+0x4254): undefined reference to `xmlFree'
http_caldav.c:(.text+0x4283): undefined reference to `icaltime_from_timet_with_zone'
How could I solve this problem of missing references?,
Thanks.
I am driving nuts....
I'm working on a program to read out Joint Coordinates from an Xtion Primesense sensor with OpenNI and NiTE. I got the program splittet in 3 parts. Main, sensorOpenNI.hpp and sensorOpenNI.cpp. Now while linking the parts together I get lots of errors saying there are undefined references to some NiTE functions. I'm working with Kubuntu and g++. The NiTE and OpenNI libs are in a directory called Include...
Here's the error message:

I'm calling g++ like this:
g++ -o test mainSensor.cpp sensorOpenNI.cpp -I Include/
Try copying the libraries libOpenNI2.so and libNiTE2 like that:
sudo cp ./OpenNI-Linux-x86-2.2/Redist/libOpenNI2.so /usr/local/lib
sudo cp ./NiTE-Linux-x86-2.2/Redist/libNiTE2.so /usr/local/lib
then do
sudo ldconfig
and now compile the program by adding -lOpenNI2 -lNiTE2
