I am trying to convert a PDF to a JPG preview, but certain PDF files are taking a really long time to process on our RH Linux server (+- 35 seconds). The same file & command on my Windows 8 development machine takes only 3 seconds. I am using GraphicsMagick 1.3.18 & GhostScript 8.70-19. I get the same results using ImageMagick. Unfortunately I can't share the PDF file in question, but here are its properties (it is only 399KB compressed & 1.1MB uncompressed):
I tested using a compressed & uncompressed version, and the results are similar. I found that both the gm convert file.pdf output.jpg and gm identify file.pdf commands take a long time.
This is the output of gm identify -version on the Linux server:

I only have this problem for some PDF files, most are processed using the same command quite quickly.
Any ideas regarding what might make this take so long?

I am unable to build rgdal (see output in code chunk below) on my AWS server. I understand from the discussion here, and here that this has something to do with missing libraries for geos and gdal, but none of the solutions suggested appears to work. If I run sudo yum install libgdal1 libgdal1-dev libgeos libgeos-dev I get the following output:
Loaded plugins: priorities, update-motd, upgrade-helper amzn-main
| 2.1 kB 00:00:00 amzn-updates
| 2.5 kB 00:00:00 1045 packages excluded due to repository
priority protections No package libgdal1 available. No package
libgdal1-dev available. Package geos-3.4.2-1.4.amzn1.x86_64 already
installed and latest version No package libgeos-dev available. Nothing
to do
I have already enabled EPEL, but it does not solve the problem.
Unfortunately I'm not very experienced with Linux, and have no idea how to move forward...

The issue is that, while GDAL is correctly built, rgdal cannot find its libraries. This is because the AWS ec2 AMI does not include /usr/local/lib in the default search path for libraries. The solution is provided in an answer to this question.
In brief:
edit /etc/ld.so.conf using sudo vi /etc/ld.so.conf to make it contain: include /etc/ld.so.conf.d/*.conf.
Edit / create a file /etc/ld.so.conf.d/libc.conf so that it contains: /usr/local/lib
Run sudo ldconfig to save changes
This makes the libraries searchable when building rgdal.
Upgrade gcc version to 5.x.x, and then run the followings (depending on the gcc version, you may have a different file of libstdc++.so.6.0.25):
cp /usr/local/lib64/libstdc++.so.6.0.25 /lib64
cd /lib64
rm -rf libstdc++.so.6
ln -s libstdc++.so.6.0.25 libstdc++.so.6
I have installed (GCC) 4.7.2 20121015 (Red Hat 4.7.2-5) already and jave also installed yum install gcc-gfortran . (Package gcc-gfortran-4.4.7-18.el6.x86_64)
But I'm getting error like :
/usr/bin/ld: cannot find -lgfortran
collect2: error: ld returned 1 exit status
make: *** [quadprog.so] Error 1
Please help me in installing -lgfortran. It seems like I need to install "Fortran -dev package providing the Fortran library". I do not know how to do that in RedHat/CentOS. Please help. I'm facing hard time in doing this.

You showed us this:

gcc is /usr/bin/gcc'
It means that you have installed Red Hat Developer Toolset and enabled it for this shell, using scl enable or a similar command. Do you still need it? If not, I suggest to disable it.
If you need DTS, you will have to install the Fortran compiler from DTS 1.1, using:
yum install devtoolset-1.1-gcc-gfortran
(Or download it directly from here, which seems to be the repository from where you got your DTS compiler.)
This will install the Fortran compiler which is compatible with the gcc compiler you have configured. Without that, the system Fortran compiler and the DTS gcc are used together, which does not work because the DTS gcc command (used for linking in the build process you quoted) is not able to locate the libgfortran.so library from the system Fortran compiler.
Alternatively, you can bring the two compilers into sync by deinstalling the DTS compiler:
yum install devtoolset-1.1-gcc-gfortran
The following compile line was looking for libgfortran at /usr/lib64/R/lib but the library is not there. Hence, the linker error.
gcc -m64 -std=gnu99 -shared -L/usr/lib64/R/lib -o quadprog.so aind.o init.o solve.QP.compact.o solve.QP.o util.o -L/usr/lib64/R/lib -lRblas -lgfortran -lm -lgfortran -lm -L/usr/lib64/R/lib -lR
As we could not locate and modify the makefile. We created a symbolic link /usr/lib64/R/lib/libgfortran.so to /usr/lib64/libgfortran.so.3 and rerun the installation steps and it resolves the linker error.
This is a work around that we follow which resolves the issue

Error while building/deploying project untitled6 (kit: Nitrogen)

All the Qt libraries are present under /sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/include/qt5/ and I have set the sysroot path correctly under my kit, but I am unable to figure out why is that my application is failing to reference those libraries. Any help on this is deeply appreciated. Thanks in advance.
The mkspec pointed to by your kit seem to be the wrong one (linux-g++), quoting from your build log
-I/opt/poky/2.1.1/sysroots/cortexa9hf-neon-poky-linux-gnueabi/usr/lib/qt5/mkspecs/linux-g++
When building for a nitrogen6x, it should likely be linux-oe-g++ instead. This is either set by default in the Qt version you selected, or can be set by modifying the Kit itself, in QtCreator's options, under "mkspec".
The error your's seeing is probably due to the fact the that the ABI & architecture of the libraries pointed are not compatible with the x86/64 code you compiled.
Also make sure to source Yocto's environment file before starting QtCreator if you encounter problems (namely compile error about "C" not found). This will setup the path to the cross-compiler. Example:
source /opt/poky/1.6.2/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
~/Qt/Tools/QtCreator/bin/qtcreator
I was able to successfully build cython on Ubuntu 14.04 from source as explained in this SE question/answer Compiling cython From source with icc and I downloaded the source code from here - Cython source code download.
The command to compile cython is
CC=icc LINKCC=icc python3.4 setup.py build
I am enclosing the build log. It is STILL using gcc for linking. Here is a sample of build log.
It appears CC=icc LINKCC=icc does NOT seem to change the linker to icc. It is still using x86_64-linux-gnu-gcc. When I set the environmental variable LDFLAGS = -lirc the environmental variable is being passed to gcc and not to icc.
Also when I put print statements in BuildExecutable.py they are not getting called.

How do I fix it ?
You need to override the linker
by setting export LDSHARED="icc -shared". That generates the icc linker. Here is an example of the build log by typing
CC=icc python3.4 setup.py build_ext
Alternatively you can also do the same by typing
LDSHARED="icc -shared" CC=icc python3.4 setup.py build_ex

You could try to add -static-intel to link options so that all Intel specific functions will be static-linked.
I have 2 versions of SDK for Qt Creator: Compiled from Open Source and Compiled from bitbake.
The Open Source SDK is working fine, but the bitbake one is having trouble recognizing the compiler. I have added the g++ compiler to build & Run and source environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabias well.
make: c: Command not found make: [moc_utils.o] Error 127 (ignored)

QMAKE = /opt/poky/charles/sysroots/x86_64-pokysdk-linux/usr/bin/qt5/qmake
As ${OE_QMAKE_CXX} is empty, that indicates to me that you haven't source environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabiasenvironment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi.
This should work to compile by hand:
. /opt/poky/charles/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
echo $OE_QMAKE_CXX
qmake
make
(Assuming you don't need to pass any extra arguments to qmake).
Then do the following:
. /opt/poky/charles/environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi
echo $OE_QMAKE_CXX
qtcreator
Note that you should start qtcreator from the same shell that you source environment-setup-cortexa9hf-vfp-neon-poky-linux-gnueabi in.
This should get you going. Otherwise I'd suggest starting by getting a small, simple Qt appliction building correctly.
For more in configuring QtCreator, you could for instance have a look at how to setup QtCreator for cross-compilation.
Update
As it seems that Qt5 isn't included in the SDK at all, we first have to generate a suitable SDK. My preferred way:
bitbake your-image -c populate_sdk
This works, as long as your image recipe includes
inherit populate_sdk_qt5
That would give you an SDK, whose sysroot would match your image.
The "older" way, is to use a special toolchain recipe. For Qt5 that would be meta-toolchain-qt5, or some recipe that includes/requires that one. In this case, you would run:
bitbake meta-toolchain-qt5
Though, the recommended way is to use the image specific SDK.
