I am currently trying to build a 3rd party project (qt 5.0.1) for Solaris and am currently stuck with the following error:
io/qtemporarydir.cpp: In member function 'void QTemporaryDirPrivate::create(const QString&)':
io/qtemporarydir.cpp:150:30: error: 'mkdtemp' was not declared in this scope
gmake[3]: *** [.obj/release-shared/qtemporarydir.o] Error 1
From what I have found out, mkdtemp should be found in stdlib.h which is in /usr/include. However looking in stdlib.h on my solaris system it soes not define the mkdtemp method.
Does anyone know of a workaround for this? (Or how I can compile Qt for Solaris...)
I have since found that there was an additional function in the Qt source which replaced mkdtemp for systems which did not define it themselves. However it was wrapped in an #ifdef statement which did not account for Solaris builds. Uncommenting the #ifdef wrapper fixed that buil

So I am trying to compile this flip fluids addon with blender, so I followed this tutorial, https://www.youtube.com/watch?v=TVKM1egDoGs , So I first ran cmake.exe -G "MinGW Makefiles" .. and it was telling me that it was missing a CMakeLists File... So I added one... then I ran cmake.exe --build . and it got to 3 percent than showed me errors like ...

This is the full error https://pastebin.com/KTnALG1E, where is this coming from?? is it a mingw error or what? Can someone help please?
Your full error message includes a more interesting bit:
C:/Users/N/Downloads/Blender-FLIP-Fluids-master/src/engine/mingw32_threads/mingw.thread.h:32:2:
error: #error This version of MinGW seems to include a win32 port of
pthreads, and probably already has C++11 std threading classes
implemented, based on pthreads. It is likely that you will get class
redefinition errors below, and unfortunately this implementation can
not be used standalone and independent of the system header,
since it relies on it for std::unique_lock and other utility classes.
If you would still like to use this implementation (as it is more
lightweight), you have to edit the c++-config.h system header of your
MinGW to not define _GLIBCXX_HAS_GTHREADS. This will prevent system
headers from defining actual threading classes while still defining
the necessary utility classes.
So either install a different version of mingw or edit your mingw files according to the instructions above.
I'm trying to build OpenCV 3.2.0 vc14 from its sources with MinGW 5.3.0 32 bit in order to use its functionality from Qt 5.8. My platform is Windows 7 64 bit.
The main instruction I follow is here, on Qt's wiki. On several steps, I encounter errors for which I haven't found solutions yet. As I am a newbie, I apologize for my helplessness and will appriciate any suggestions.
Error 1. On the stage of generating build files.
In cmake-gui (cmake-3.2.1-win32-x86), I precisely follow the steps specified in the Qt wiki article mentioned above. However, during the final generation, the following CMake error occurs at the end:
CMake Error in modules/highgui/CMakeLists.txt:
No known features for CXX compiler
"GNU"
version 5.3.0.
Generating done
I wonder how it affects the project files and if it causes the next errors.
Error 2. When trying to build OpenCV
The build process is interrupted midway, logging the following:

NOTE: I also had sprintf() family security error. So I followed Alex's suggestion to add add_definitions(-DSTRSAFE_NO_DEPRECATE) to the beginning of CMakeLists.txt to suppress the error.
Thank you for your time.
I use MinGW64+msys on Winodws7 64bit
Now I’m trying to build CMAKE but I can’t.
When I typed ./configure soon an error happened. .

Error when bootstrapping CMake:
Cannot find appropriate C++ compiler on this system.
Please specify one using environment variable CXX.

I also find error messages in Bootstrap.cmk/cmake_bootstrap.log like bellow.

They said cwchar and iostream.h doesn't exist, although I have them and set their path to environmental variable.
The first massage said my C++ compiler isn’t appropriate. I installed it by mingw-get.exe.
Does anyone know, how can I get appropriate C++ compiler?
You mixed two compilers. I recommend: delete your old one and install msys2+mingw64.
I am having a hard time figuring out how to add getopt.h in my AIX 7.1. I am using the getopt_long function in my code, which I know is in getopt.h instead of unistd.h (which contains getopt()).
This code is not compiling in AIX:
fatal error: getopt.h: No such file or directory
#include <getopt.h>
^
compilation terminated.
Here are the gcc packages installed:
gcc-4.8.3-1.aix7.1.ppc.rpm
gcc-c++-4.8.3-1.aix7.1.ppc.rpm
libgcc-4.8.3-1.aix7.1.ppc.rpm
gcc-cpp-4.8.3-1.aix7.1.ppc.rpm
I have gone through these links, but they haven't helped much:
http://www.ibm.com/developerworks/aix/library/au-unix-getopt.html#sthash.Loz3H0AH.dpuf
http://www.linuxmisc.com/8-freebsd/eb9bdab1cf6044d5.htm
Also a lot of other web searches.
Am I missing some rpms, or some environment variables?
getopt_long is GNU-only, but you can take free implementation (for example, this claims that it is of BSD license, if I understand it right) or write your own implementation (it's not so hard) and use it in your code.

mingw32-make: *** [build/bitcoin.o] Error 1
After reading on bitcoin forums, I found a post by shakezula that mentioned this was frequently a result of missing "__NO_SYSTEM_INCLUDES". However, that is included in my .pro file, which you can find here:
http://pastebin.com/4p4BMPAE
Thanks for your help.
I managed to fix this by downloading the CoinLab build environment; for those interested, the QT version was 4.8.4, with MinGW as the version bundled with GCC 4.6.2.
I'm right where you are when you posted this atm. Kinda stuck here as well... Are you using Qt 5.2? I think we may need to use 4.8.5 to get anything done.
