I want to interface FCGI with my C++ code in a server that runs ubuntu. I didn't find ubuntu under the list of tested platforms in the FCGI website, but I tried building it anyway.
./configure seems to work okay. But, when I run make, I get 2 errors, as pasted below:
fcgio.cpp: In destructor 'virtual fcgi_streambuf::~fcgi_streambuf()':
fcgio.cpp:50: error: 'EOF' was not declared in this scope
fcgio.cpp: In member function 'virtual int fcgi_streambuf::overflow(int)':

make[1]: Leaving directory '/home/giridhar/fcgi-2.4.1-SNAP-0910052249'

Help in fixing this issue would be greatly appreciated.
I noticed that EOF is a C macro and it requires stdio.h which wasn't included in the fcgio.cpp file.
Adding a #include <stdio.h> to the fcgio.cpp file solves the problem, and now FCGI builds fine on Ubuntu.

I'm trying launch cv_camera with ros but I couldn't compile this package in ros, I launched this command:
catkin_make --only-pkg-with-deps rossumo cv_camera -DARDRONESDK3_PATH=~/out/arsdk-native/staging/usr
...
/home/docker/catkin_ws/src/cv_camera/src/capture.cpp: In member function ‘void cv_camera::Capture::open(const string&)’:

What do you think I'm doing wrong?
Thanks!
I have been trying to build opencv for over a week now using the instructions at
http://docs.opencv.org/doc/tutorials/introduction/linux_install/linux_install.html and http://miloq.blogspot.com/2012/12/install-opencv-ubuntu-linux.html however every time I get to the 'make' step, I get an error:

The process works well for a while and then stops at 79% with the above error. I thought the problem might be caused by the fact that I did not have the OpenCL library installed. I installed it as shown at www.amd-dev.wpengine.netdna-cdn.com/wordpress/media/2013/07/AMD_APP_SDK_Installation_Notes.pdf and still no luck. I am running ubuntu 12.04 and OpenCV 2.4.9. The installed version of AMD APP SDK is 2.8.1.0. Please help. I am at my wits end here.
I experienced the same problem and solved it for me by compiling OpenCV without modules needing GPU functionality using the following cmake command in the release folder:
cmake -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_OPENCL=OFF -D WITH_CUDA=OFF -D BUILD_opencv_gpu=OFF -D BUILD_opencv_nonfree=OFF -D BUILD_opencv_stitching=OFF -D BUILD_opencv_superres=OFF ..
The following modules are then deactivated: gpu, nonfree, stitching, superres
I get the error
$ ./build_native.sh

From reading this it appears that inside your HelloWorldScene.cpp you have typo.
CCsprite should be CCSprite.
This is just one error, there may be many more, it is impossible to tell from what you have posted.
I am attempting to build fastcgi on a Linux Ubuntu 10.x machine.
I run the following commands:
./configure
make
and I get the following error:

I notice that others have had the same problem and have asked this question in various fora etc - however, I have not as yet, seen an answer to this question/problem.
Has anyone ever managed to build fastcgi on Linux?
How do I fix this problem?
EOF is a C macro and seems that you do not have it defined in fcgio.cpp or that something has undefined it. I would first try to add #include <stdio.h> to start of fcgio.cpp.
I had the same problem on Ubuntu 11.10 Linux 64bit. Following most of #paercebal's advice I created the following patch which resolved the problem:
--- include/fcgio.h 2012-01-23 15:23:51.136063795 +0000
+++ include/fcgio.h 2012-01-23 15:22:19.057221383 +0000
## -31,6 +31,7 ##
#define FCGIO_H
#include <iostream>
+#include <stdio.h>
#include "fcgiapp.h"
I'm using stripped down as much as possible configuration of Qt but now I need to use the dbus and can't figure out what I need to include to be able to use it? There doesnt seem to be anything obvious to me using the qconfig tool. The errors I get at the moment when making are:

Does anyone know a module that I must not be including which is necessary or how to find out? thanks
QT += dbus
should be enough to include the dbus option in the .pro project file, ins't it?
I need more info to give apropriate answer.
