I'm trying to install Cassandra cpp-driver in Ubuntu.
I've done the steps specified in DataStax C/C++ Driver for Apache Cassandra (Beta), but i keep getting the following compile error.

I've already fixed this compile errors in Cassandra cpp-driver, by down-versioning libuv to version libuv-0.10, the compile errors will be gone.
It seems that the latest updates for libuv is not yet supported by Cassandra cpp-driver.

Following on from a previous question, I was pointed to an answer. The answer however involved a lambda function and I am trying to pass a normal function through.
Using the below code as an example:
#include <iostream>
#include <functional>
void forloop(std::function<void()> func, int arg) {
func(arg);
}
void print(int number) {
std::cout << number << std::endl;
}
int main() {
int n = 5;
forloop(print, n);
}
The following error is returned in CLion.

Apologies if this questions seems silly - I am a C++ noob.
std::function<void()> means "function that returns void and takes no arguments". You're trying to pass print instead, which is a "function that returns void and takes an int". The types are mismatched.
Change forloop to:
void forloop(std::function<void(int)> func, int arg) { /* ... */ }
Also, don't use std::function to pass lambdas unless you have a good reason to do so. I suggest reading my article on the subject: "passing functions to functions".
opencv installation using mingw32-make command in windows 10 platform, then likely end up in getting the below error.

Please suggest me in installing.

I also faced the same problem while trying to build OpenCV 3.2.0 using mingw32 on Windows10. I searched a bit to find a fix on Github for similar problem. It said the problem was:
MinGW defined _CRITICAL_SECTION and _RTL_CRITICAL_SECTION as two separate (equivalent) structs, instead of using typedef
So, you have to add another typedef GTEST_CRITICAL_SECTION for _CRITICAL_SECTION and _RTL_CRITICAL_SECTION and use this typedef for either case.
Here is what to do :
Edit "ts_gtest.h" which is inside "opencv\sources\modules\ts\include\opencv2\ts\"
Replace this line (probably line 723)
// assuming CRITICAL_SECTION is a typedef of _RTL_CRITICAL_SECTION.
// This assumption is verified by
// WindowsTypesTest.CRITICAL_SECTIONIs_RTL_CRITICAL_SECTION.
struct _RTL_CRITICAL_SECTION;
with
#if GTEST_OS_WINDOWS_MINGW
// MinGW defined _CRITICAL_SECTION and _RTL_CRITICAL_SECTION as two
// separate (equivalent) structs, instead of using typedef
typedef struct _CRITICAL_SECTION GTEST_CRITICAL_SECTION;
#else
// Assume CRITICAL_SECTION is a typedef of _RTL_CRITICAL_SECTION.
// This assumption is verified by
// WindowsTypesTest.CRITICAL_SECTIONIs_RTL_CRITICAL_SECTION
typedef struct _RTL_CRITICAL_SECTION GTEST_CRITICAL_SECTION;
#endif
Replace this line (probably on line 3060 before your edit - line number would have changed as you modified first part)
_RTL_CRITICAL_SECTION* critical_section_;
with
GTEST_CRITICAL_SECTION* critical_section_;
These two changes should fix your above error.
It was fixed by using TDM-gcc mingw compiler.

If anybody faced the same issue or has any idea on how to resolve it, please give your solution...
Looking at the man page for strerror_r, I see:
int strerror_r(int errnum, char *buf, size_t buflen);
/* XSI-compliant */
char *strerror_r(int errnum, char *buf, size_t buflen);
/* GNU-specific */
Note the difference in return type.
Looking at your error message:
error: invalid conversion from 'int' to 'const char*' [-fpermissive]
return std::string(strerror_r(errorCode, errmsg, 256));
^
It seems that the source you're compiling is expecting the GNU-specific version of strerror_r, but getting the XSI-compliant one. Either your target does not provide the GNU extension, or your toolchain is not set up correctly.
The man page goes on:
Feature Test Macro Requirements for glibc (see feature_test_macros(7)):
The XSI-compliant version of strerror_r() is provided if:
(_POSIX_C_SOURCE >= 200112L || _XOPEN_SOURCE >= 600) && ! _GNU_SOURCE
Otherwise, the GNU-specific version is provided.
So you might want to investigate in that direction. (What is _POSIX_C_SOURCE, _XOPEN_SOURCE and _GNU_SOURCE set to when you're trying to compile?)
I am trying to compile the newest version of the Armadillo Linear Algebra library (4.300.8) and am running into the following errors when running make after cmake . runs successfully.

I am using gcc version 4.7.3 and running Ubuntu 12.04.
Thanks!
It looks like the HDF5 library is causing problems. Uninstall the HDF5 library, and then reinstall Armadillo.
Another option is to update your system to Ubuntu 14.04. The previous Ubuntu LTS release (12.04) is ancient by open-source standards.
I'm new using Boost serialization. I'm using xml serialization and the non intrusive version. I followed the tutorial (from Boost website) step by step and my code works fine.
The problem arise when I put my class (the code is divided in .h and .cpp plus a main.cpp file) in a namespace (ns_mytests). In this case the compiler (g++) complains and I have the following errors:

It's sure that I'm doing wrong something, but I could't find my error.
Any help is appreciated.

Define the non-intrusive save in the namespace where the type to be serialized is defined.
