I'm desperately trying to compile Tesseract-ocr (4.0) on a Windows Machine with some restrictions.
We are doing multi-platforms : an automated compilation must be possible (command-line)
We are using specific 3rd party libraries : the compilation must accept custom path / libraries for most of its dependencies
We are already using most of the 3rd party libraries for other part of the code : the compilation must not recompile them (thus, no cppan)
Leptonica has been built with our special 3rdparty (ZLib, LibPng ..)
Our project must "include" tesseract alongside theses specific 3rdparty
Problem :
I have strong issue specifying custom paths for Tesseract.
Under Unix (CentOS, Ubuntu 16/18, Debian 8/9 ..), I was able to achieve my goal with the tools autogen autoconf autoheaders pkg-config.
Under Windows, autoconf-archive and pkg-config are unavailable (from what I tried) ; rendering autoconf unusable.
I was neither able to compile using CMake and specifying a custom path for Leptonica (even after writing a new pkgconfig for leptonica).
Things I tried :
Using MinGW and autoconf
Manually installing pkg-config
Cheating with autoconf-archive .m4 into aclocal
Creating a VisualStudio project with cppan and modify it
Various ways of telling CMake to search elsewhere for 3rdparty
Things that work on Linux :
Autoconf with modified PKGConfig for custom compiled Leptonica (--with-extra-libraries PKG_CONFIG_PATH CPPFLAGS LDFLAGS)
Things I have not tried :
Installing Leptonica on the machine (Not the point here)
Rewriting CMakeFiles
Unknown solutions ?
Possible Solutions
MinGW (Windows) with pkg-config autoconf-archive
Unknown way to tell CMake Leptonica custom path
VisualStudio project without cppan
Yours ?
Thank your for your interest.
EDIT 1
By trying various ways of manually installing pkg-config, Autoconf seemed to be unaware of its presence. This error was about pkg-config missing package (How to install pkg config in windows?).
CPPAN was deeply part of the visual studio project and I couldn't see how I could separate them.
I usually tell configure to look for leptonica package with the arguments --with-extra-libraries and PKG_CONFIG_PATH.
CMake however, uses the "macro" find_package(Leptonica $PATH CONFIG REQUIRED). By looking at it a little bit, I was (maybe) able to specify its path with CMAKE_PREFIX_PATH, CMAKE_MODULE_PATH, Leptonica_DIR. The compilation was still unsuccessfull due to missing config files (LeptonicaConfig.cmake or leptonica-config.cmake).
I pointed theses variables to various folders of the leptonica folder after building it.
For information, I built Leptonica with its configure as such :
bash configure --enable-shared=false --without-giflib --without-libwebp --without-libopenjpeg LDFLAGS="-LPATH/TO/ZLIB -LPATH/TO/LIBPNG .." CPPFLAGS="-IPATH/TO/ZLIB/INCLUDE ..."
I, however, was unable to locate theses files (while seeing a LeptonicaConfig.cmake.in under LeptonicaDir/cmake/template)
I hope I answered your questions. Please tell me if you need further details.

In my code I'm getting a fatal error of :
fatal error: gmpxx.h: No such file or directory|
I'm trying to use the The GNU Multiple Precision Arithmetic Library, but I'm having trouble trying to get the library downloaded an working in the right place.
I download the file gmp=6.1.0.tar.lz but I have no idea how to open it, use it, or even where it needs to be placed.
I'm using Codeblocks, and a Windows 10 computer.
First, install some basic GNU utilities via MinGW. We need tar. Then, download a stable lzip release. Choose tarball not lzip archive, because we want to build lzip. Now, open your MSYS shell, go to directory made after extracting lzip tarball (this directory should be available as /c/<PATH ON C DRIVE WITH BACKSLASHES REPLACED WITH SLASHES>) and run:
./configure --prefix=/
make
make install
Then go up (cd ..) and run:
tar xvf gmp-6.1.0.tar.lz
It should extract this file. Now, build GMP by going to directory gmp-6.1.0 and running:
PATH="/c/Program Files/CodeBlocks/MinGW:$PATH" ./configure --prefix='/c/Program Files/CodeBlocks/MinGW'
on 32-bit system, or:
PATH="/c/Program Files (x86)/CodeBlocks/MinGW:$PATH" ./configure --prefix='/c/Program Files (x86)/CodeBlocks/MinGW' --enable-cxx
on 64-bit. Run these commands:
make
make install
You should have GMP installed.
how to use and install SystemC in terminal mac OS X?
I tried the Logic poet application, But i use os x 10.10 so it doesn't work.
so i want to know how can i compile and execute SystemC in terminal.
I could't find the detail of SystemC in terminal.
Thank you
The other answer is correct and perfectly fine, however, I thought I'd also answer and provide a little more detail.
Install Apple's "Command Line Tools"
You have two options: install Xcode (a big download), or just the command line tools (a much smaller download). If your goal is simply building SystemC applications at the command line, then I recommend the latter.
Install Apple's "Command Line Tools" by launching Terminal, entering
$ xcode-select --install
then clicking Install. After that, you'll have make, clang and more available at the command line.
Build and install Accellera's SystemC implementation
Download the latest release from the Accellera Downloads page (annoyingly, you'll have to provide a few personal details) and extract the contents of the .zip file.
I like to keep a copy of the SystemC source code available, because it can be useful for debugging or understanding how something works. Therefore, I move the extracted folder (systemc-2.3.1) into ~/Work/Other. That's where I keep source code for third party libraries. However, you can put it wherever you like.
Open Terminal, change into the extracted folder (systemc-2.3.1), and execute:
$ mkdir build
$ cd build
$ export CXX=clang++
$ ../configure --with-arch-suffix=
$ make install
The --with-arch-suffix= option prevents a -macosx64 suffix being add to the lib folder name, allowing your build scripts to be simpler.
After that process, the salient include and lib folders should be available within the systemc-2.3.1 folder.
Configure your build environment
There are many ways you can do this; I have a simple approach that I believe is close to what the SystemC maintainers envisioned. I define two environment variables in my .bash_profile (which is executed for every new Terminal session on OS X):
export CXX="clang++ -fcolor-diagnostics"
export SYSTEMC_HOME=~/Work/Other/systemc-2.3.1
Build a SystemC application
You could use Make, the quintessential build tool, which you get with Apple's "Command Line Tools", or any one of the plethora of other options. I use SCons with SConstruct files that look something like this:
import os
env = Environment(CXX=os.environ["CXX"],
SYSTEMC_HOME=os.environ["SYSTEMC_HOME"],
CPPPATH="$SYSTEMC_HOME/include",
LIBPATH="$SYSTEMC_HOME/lib")
env.Program("main.cpp", LIBS="systemc")
View trace (VCD) files
Scansion is a nice tool for this. GTKWave is another option, but it's a bit clunky.
Ensure you have xcode command line tools installed.
Follow instructions provided in the official repository.
From personal experience.
Compiling SystemC library with clang results in segmentation fault: 11
error every time I include systemc library into my code. To avoid this use gcc instead.
Note that I use gcc-8, installed with homebrew.
$ cd path/to/systemc-2.3.3
$ mkdir objdir
$ cd objdir
$ export CXX=g++-8
$ ../configure
$ make
$ make install
Use $ make check to launch examples compilation and unit tests.
To compile and run hello world example:
$ export SYSTEMC_HOME=path/to/systemc-2.3.3
$ g++-8 hello.cpp -o hello.o -L $SYSTEMC_HOME/lib-macosx64 -I $SYSTEMC_HOME/include/ -l systemc
$ ./hello.o
Tested on macOS 10.13.6; gcc version 8.2.0; systemc-2.3.3
Install
Go here click the first link and fill in your information to get the source code
http://www.accellera.org/downloads/standards/systemc
Then cd to the folder
Then run the following commands
./configure --with-unix-layout
gmake
sudo gmake install
gmake clean
After you do that it should all be saved in your use/local/(lib&include) directories
To Use
In code do this
#include "systemc.h"
I use a single makefile normally. But you could write the following to link the library. Given your cpp file is called main.
g++ -o main main.cpp -I/usr/local/include -L/usr/local/lib -lsystemc
I've downloaded tar.gz files from official site(versions 2.4.3, 2.4.7, 2.4.8). Then unzipped them somewhere.
mac-mini-olia:Data olia$ cd opencv-2.4.6.1/
mac-mini-olia:opencv-2.4.6.1 olia$ mkdir build
mac-mini-olia:opencv-2.4.6.1 olia$ cd build/
mac-mini-olia:build olia$ cmake -G "Unix Makefiles" ..
mac-mini-olia:build olia$ make -j8
after the last command output is
3910 warnings and 12 errors generated.
Errors are like
/Volumes/Data/opencv-2.4.6.1/3rdparty/libjpeg/._jcapimin.c:1:4096: error: source file is not valid UTF-8
and
/Volumes/Data/opencv-2.4.6.1/3rdparty/libpng/._pngerror.c:1:2: error: expected identifier or '('
And after that in /usr/local/lib and /usr/local/include there are no files of opencv.
There are multiple ways to install OpenCV on OSX.
You can use MacPorts
Make sure you have XCode installed with it's Command Line Tools first.
(An easy way to test that is to see if xcodebuild if a found command in Terminal)
After you install MacPorts simply do
sudo port install opencv
This will take care of building the project from source and installing it for you.
(The path might be /opt/local/lib /opt/local/include though, haven't used it in a while)
There are also port variants: opencv with options. For example if you plan to use openni 1.5.x and have it integrated with opencv you can try
sudo port install opencv +openni
If you do
sudo port variants opencv
you should get a list of all the options(e.g. python support, qt support, etc.)
If you want to build from source yourself, I recommend installing the ccmake command (I think macports can also do that for you) or use the CMake gui tool. This will allow you to easily configure the build and setup your install location(/use/local/...and so on)
So you can try someting like this:
cd /path/to/your/opencv_folder
mkdir build && cd build
ccmake ..
At this stage you should see something like this:
hit Enter to change an option and Enter again to exit edit mode and use the up/down keys to scroll through the options. When you're happy with the settings, press C to configure. Once that's done, you can press G to generate. This will generate the makefiles for you so you can do this:
make
sudo make install
make install will actually copy the built libraries/headers to the /usr/ folder.
You might run into errors when running make, depending on your setup(e.g. if you're missing dependencies, etc.), but the cool thing about ccmake is that you can go back, run it again, disable the things you don't want to build right now and go back to the make stage.
I am trying to include ZMQ sockets in a Go app but both zmq4 and gozmq (the referred ZMQ binding libraries for Go) are giving me problems. I would like to understand why zmq4 specifically isn't importable on my system.
I am running a Windows 8 system and I used the windows installer from the ZMQ website for version 4.0.3. I am primarily concerned about getting zmq4 set up and here is the result of my "go get" query on the github library's location:
> go get github.com/pebbe/zmq4
# github.com/pebbe/zmq4
polling.go:4:17: fatal error: zmq.h: No such file or directory
compilation terminated.
This issue is not alleviated by cloning the Github repository - the error remains the same.
I know the issue has to do with the C library zmq.h that is located in the "include" folder of my ZMQ installation, but whether the dependency is held up by a pathing issue or an external tool issue is a mystery to me.
A similar error has come up in regards to node.js and is the solution I see others referred to, outside of node scripting, but it was unsuccessful in my case.
I've so far included the path to the "include" folder in my PATH environment variable and previously placed zmq.h inside of the zmq4 top-level folder. I don't have much of an arsenal otherwise to understand this problem because I am new to C and C-importing packages in Go
I wanted to do the same thing, but on Windows 7, and here is what I had to do.
Since the Go bindings are using cgo to integrate with zeromq, you need zeromq built with gcc. There are no pre-built binaries, so you'll have to build them yourself, with mingw or similar, but this process is easier than it may sound, and nicely described on the zeromq site.
As #photoionized pointed out, C_INCLUDE_PATH and LIBRARY_PATH need to be set when building the Go bindings.
(In my case, I ran into a problem when compiling libzmq with IN6_ADDR not being defined. The only solution I found was, inspired by this issue, to manually add the line #include <in6addr.h> to the windows.hpp file.)
The Windows installer version of ZeroMQ won't work with zmq4, you need to compile from source with gcc, I recommend using MSYS2.
Install and update MSYS2 following the instructions from
http://sourceforge.net/p/msys2/wiki/MSYS2%20installation/
Start the mingw32_shell.bat or mingw64_shell.bat based on Go arch (32bit or 64bit)
pacman -S mingw-w64-(x86_64|i686)-toolchain make (x86_64 for 64bit, i686 for 32bit)
cd into zeromq src folder (C:\ path starts with /c/ inside the shell)
./configure
make
make install
CGO_CFLAGS=-I/usr/local/include CGO_LDFLAGS=-L/usr/local/lib go get github.com/pebbe/zmq4
Copy the following dlls and put them next to your go program (.exe):

/mingw(32|64)/bin/libgcc*.dll
/mingw(32|64)/bin/libwinpthread*.dll
/mingw(32|64)/bin/libstdc++*.dll
Here's updated steps for #user2172816's MSYS2 solution:

An updated answer using MSYS2.
Install MSYS2 MSYS2 installation guide.
Make sure to choose the correct installation 32bit or 64bit.
Open the appropriate shell MSYS2 MinGW 64-bit or MSYS2 MinGW 32-bit. All further steps assume you are using this shell.
Update packages following instructions at the installation guide.
Install libtool pacman -Sy libtool.
Download zmq source code to a location of your choice.
Navigate to the zmq source folder.
To generate the configure file, run the autogen tool by running ./autogen.sh.
In the probable case that step 8 fails:
Find the file at fault (probably version.sh).
Replace line endings by (replace file by the actual filename).
cp file file.bak
tr -d '\r' <file.bak> file
If this fails you'll have to dive in the code and find the problem.
Run the configure tool ./configure.
In the probable case of failure. Comment out empty else clauses in the configure file.
Add Go to Path: PATH=${PATH}:<go bin directory>.
Install Go Package: CGO_CFLAGS=-I/usr/local/include CGO_LDFLAGS=-L/usr/local/lib go get github.com/pebbe/zmq4
To install ZMQ in windows: Problem in Installing Golang ZMQ for windows - fatal error: czmq.h: No such file or directory

i recently got Oracle Solaris on my VM to test some code on it, i was unable to install gcc since i dont really know how, i googled alot but all info is about oracle compilers, i needed GCC, any idea where can i get GCC or how to install it?
thanks
The original answer applied to Solaris 11 Express/non-official release - if you're doing this today with a full release of Solaris 11.x, use the pkg install command like you see in xavier's response.
Run this command from your terminal to install GCC.
For GCC 3.4.x
pkg install gcc-3
For GCC 4.5.x
pkg install gcc-45
For GCC 4.7.x
pkg install gcc-47
For GCC 4.8.x
pkg install gcc-48
The gcc command should then already be placed in your path /usr/bin/gcc, which is a symlink).
Old Answer
Solaris 11 should already have gcc installed in /usr/sfw/bin/, but it's probably not in your PATH. Try this at the prompt: /usr/sfw/bin/gcc
Two steps:
pkg install gcc-45
pkg install system/header
that is all
if you see more info
http://blog.csdn.net/zjg555543/article/details/8217769
Just download gcc from its homepage, follow one of the mirror links to fetch the latest binary package (in .tar.gz or tar.bz2 format), and use traditional steps to build:
./configure --<> // give your options
make
make install
The good news is you can customize what you need and always stay with the latest, while bad part is you may lose the power to debug with mdb/adb - we are facing such problems with latest GCC 4.6.x
Solaris 10 and prior version :
/usr/sfw/bin/gcc works.
Solaris 11 :
pkg install gcc-3
pkg install gcc
worked for me
This will install entire gcc collection on your machine. Which anyways will be required
My Solaris 2.11 does NOT have internet access :/
What work for me:
(1) I use this link as guideline
(2) From my windows machine, download gcc at one of their mirror sites, i used here, normally the closer the better
(3) Upload gcc-9.2.0.tar.gz to target /tmp directory using WinSCP
(4) tar -xvf gcc-9.2.0.tar.gz
(5) cd gcc-9.2.0
(6) mkdir /usr/local/gcc
(7) cd /usr/local/gcc
(8) /tmp/gcc-9.2.0/configure -v --program-suffix=9.2
At this point, you might get this error:
Building GCC requires GMP 4.2+, MPFR 2.4.0+ and MPC 0.8.0+.
(9) Manually download the required files here.
Note: To know what files are required, check contrib/download_prerequisites
(10)Copy over the files in (9) to /tmp/gcc-9.2.0
(11)Extract, then create shortcuts: ln -s gmp-6.1.0 gmp, ln -s mpc-1.0.3 mpc, ln -s mpfr-3.1.4 mpfr, ln -s isl-0.18 isl
(12)/tmp/gcc-9.2.0/configure -v --program-suffix=9.2 --enable-languages=c,c++ -v
(13) nohup gmake & (At this point it's going to take some time...mine took ~6 hours. Use -j option if you can, to gmake it faster )
(14) gmake install
(15) /usr/local/bin# ./gcc9.2 --version
gcc9.2 (GCC) 9.2.0

Voila! :-)
You can install gcc 4.3 from OpenCSW:
pkg-get -i gcc4code gcc4g++
I also had to run mkheaders manually after the install.
I had the same problem and 'pkg install gcc-3' worked for me.
I'll quote the answer from unix.stackexchange.com.
On Solaris 11 gcc is not installed by default. Normally you'll want more than just the compiler itself so my answer will include all the usual suspects for building open source software on Solaris that you've downloaded from somewhere in source code format.
By far the easiest is to use IPS to install it using the commands below (while being root or other superuser):
pkg install pkg://solaris/developer/build/gnu-make \
pkg://solaris/developer/build/make \
pkg://solaris/developer/gcc \
pkg://solaris/system/header \
pkg://solaris/developer/build/autoconf \
pkg://solaris/developer/build/automake
(I use fully qualified package names here, that is not really necessary)
Note that some of the packages are available in the official repo in various versions. If you just reference developer/gcc then you'll at the time of writing this get GNU C v4.8.2, but you may explicitly ask for a prior version, e.g. by using package name such as developer/gcc-45.
