I am trying to do some performance analysis of HTTP/1.1 and HTTP /2. But I have not been successful in installing the later one. I need both the protocols from the same implementation (e.g. H2O). The first problem I got while installing H2O is the openssl version in ubuntu 14.04. The I updated the version to 1.0.2 as suggested by 1. Then I got the following error messages:
In function `h2o_socket_ssl_get_selected_protocol':
/tmp/h2o/lib/common/socket.c:499: undefined reference to `SSL_get0_alpn_selected'
CMakeFiles/h2o.dir/lib/common/socket.c.o: In function `h2o_ssl_register_alpn_protocols':
/tmp/h2o/lib/common/socket.c:542: undefined reference to `SSL_CTX_set_alpn_select_cb'
collect2: error: ld returned 1 exit status
make[2]: *** [h2o] Error 1
make[1]: *** [CMakeFiles/h2o.dir/all] Error 2
make: *** [all] Error 2
Can anybody please help me here.
Try using Nginx. There is a lot more support for it. H2O is a little more complicated to setup and the docs aren't as well written.

I'm trying to install an R package 'cubature' in a Linux-based remote server which uses SLURM as manager.
Given that I'm a user of the server, I do not have root access. I tried to install the R package locally, but I do get the following error:
In file included from ./src/divonne/common.c:14:0,
from ./src/common/CSample.c:77,

It seems that R cannot find the right compiler for installing the R package.
Do you have any suggestion on what I should do?
Recently we have downgraded R(latest) to 3.3.0 to RHEL.
Which requires to install xlsx and other rJava dependent packages, though I have deep dived into every possible duplicate and tried all options.
Details:
Command Executed
R CMD javareconf
Error:
.rodata' can not be used when making a shared object; recompile with -fPIC
/usr/lib64/R/lib64/R/lib/libR.a(CommandLineArgs.o): could not read symbols: Bad value

make[2]: *** [libjri.so] Error 1
make[2]: Leaving directory /tmp/RtmpH1WhQR/R.INSTALL4a1266bbb309/rJava/jri/src'
`
Net search: I searched and found following link
https://github.com/BVLC/caffe/issues/2171 suggests to use
export CXXFLAGS=-fPIC
but no luck also I do not see CMakeCache.txt in the R folder, still not clear which piece I am missing and any help will be highly appreciated.
NOTE: This might seem to be a duplicate, but seriously I have already tried all the related/relevant posts on stackoverflow.
I resolved this, by manually placing the rJava folder(which I had in a different environment while we used R latest version), while entering into R add this following command before installing rJava dependant libraries:
.libPaths("/usr/lib64/R/library")
Change the path to the path where R is installed.
Hope this helps.
I am trying to compile qtwebengine for raspberry pi using
[http://wiki.qt.io/RaspberryPi2EGLFS ](link url)
AND
compilation terminates with following errors :

What am I missing? It says about qtwebchannel but I have successfully installed qtwebchannel.
Please help. I have been trying for more than 2 weeks
I was able to solve this problem by rebuilding the QtWebChannel:
~/raspi/qtwebchannel$ make
and then going back to the QtWebEngine:
~/raspi/qtwebengine$ make
This builds the libQt5WebEngine.so
Past few weeks I have been trying to setup Qt native build environment on Raspberry Pi.
I followed steps mentioned in Native Build of Qt 5.4.1.
Since I do not use USB Hard Disk, I omitted following steps:
Unpacking source to an external USB HDD
Increasing available RAM for concurrent compilation
Instead I extracted to moved to path: cd ~/opt/qt-everywhere-opensource-src-5.4.1
and for compilation I ran: make 2>&1 | tee make.out
I tried Qt 5.4.1 to build on Jessie version of Raspbian OS, but it failed. I found similar error someone posted and tried to reply but no response at the end.
And now I tried Qt 5.4.1 on Wheezy version, and I get different error:
/home/pi/opt/qt-everywhere-opensource-src-5.4.1/qtwebkit/Source/JavaScriptCore//libJavaScriptCore.a: member /home/pi/opt/qt-everywhere-opensource-src-5.4.1/qtwebkit/Source/JavaScriptCore//.obj/dfg/DFGThunks.o in archive is not an object

Can someone tell me why this occurs? Is this Qt code issue? Is there a way to resolve this?
I'm using CentOS 6.4 and I'm trying to install the R package 'rPython'. It failed with following messages. Anybody knows how to fix this? Thanks!

It seems that the default installation of Python on RHEL / CentOS,
etc. is not "shared enabled", i.e., it does not include libpython*.so. Just the libpython*.a static library. This prevents some Python
applications to run properly. There are instructions in different
places, (e.g., here or here) indicating how to install Python as a shared library on CentOS and related Linux flavours.
