undefined reference but I have installed libical - c++

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:
CFLAGS=-I/usr/include/libxml2/libxml make
Some of the errors:

How could I solve this problem of missing references?,
Thanks.

undefined reference to `curl_easy_init' on CLion/Mingw [duplicate]

This question already has answers here:
How to add "-l" (ell) compiler flag in CMake
(2 answers)
Closed 3 years ago.
I am trying to use curl inside c++ code. How should i do it properly ?
I have pasted libcurl.a & libcurl.dll.a in this directory:
C:\Program Files\mingw-w64\x86_64-8.1.0-posix-seh-rt_v6-rev0\mingw64\lib
This is my CMakeLists.txt from CLion/Mingw

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++14 -lcurl.dll")
add_executable(tan Tan/mail.cpp)

When I add "#define CURL_STATICLIB" i get these errors:

If anybody comes looking use this in CMakeLists.txt. The last line solved the issue.
Step1:
Copy libcurl.dll.a in C:/curl.
No need to copy "libcurl.a" OR "libcurl.dll.a" at any other place.
No need for #define CURL_STATICLIB in main.cpp file
Step2: Edit the CMakeLists.txt as below.
set(CMAKE_CXX_STANDARD 14)
add_executable(tan Tan/mail.cpp)
project(untitled6)
target_link_libraries(tan "C:/curl/libcurl.dll.a")
Step3: If your program flashes quickly and closes. You might be missing some dll files. To check which ones you are missing , run the program (in my case tan.exe) with cmd. Take that dll from curl package (in my case curl-7.65.0-win64-mingw) and put it along side of your executable file. Make sure curl and your executable is compiled with same compiler. In my case it's Mingw.

Cassandra c++ driver "undefined reference" error

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:

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

Generating .dll files with dllwrap for Visual Studio 2012 (ARPACK)

I am trying to make .lib file of ARPACK library to use with VS2012 Express Edition. Hence I am using the command in MSYS as :
dllwrap --export-all-symbols BLAS/.o LAPACK/.o SRC/.o UTIL/.o
-lgfortran --output-def arpack_win32.def -o arpack_win32.dll
This results in error:

UTIL/svout.o:svout.f:(.text+0x1cd): undefined reference to

Cant figure it out why this happens....Thanks..

Finally figured out what was wrong....I was using MinGW with gfortran..... Adding C:\MinGW\bin to PATH solved all the issues.....

How to compile Botan and Qt on Windows?

I'm writing a Qt application that uses Botan. For the Windows version I decided to use the precompiled DLL, so I downloaded the installer, installed Botan in C:\botan and added:
win32:INCLUDEPATH += C:/botan/include
win32:LIBS += -L"C:\botan" -lbotan
to my .pro file. However I'm getting linker errors (undefined reference to...) during the build process, and I can't see why - the correct .lib is specified in LIBS, the include path is fine.
I'm using MinGW.

Since Botan is included in QtCreator (2.x branches), you could just recompile QtCreator (or take the relevant parts), and use that. No messing with any makefiles (mingw works out of the box), and since you mention Qt, this will probably work very well.

As far as I know, official binaries are compatible with MSVC only. I guess you should build Botan from source to use it with MinGW. According to docs it's relatively easy to do:
$ python configure.py
$ make
$ make check
$ make install
But for me compiler autodetection didn't work as expected, so I had to do few additional steps:
Autoconfiguration:
$ python configure.py --cc=gcc
Edit generated Makefile. Replace line
LINK_TO = -ladvapi32.lib -luser32.lib
with
LINK_TO = -ladvapi32 -luser32
Build
$ make
$ make check
$ make install

I've used this command to build botan using mingw32-make.exe, i've ran it in a console window with Qt support.
