I'm trying to compile a .cpp file but I must install libssh2. I have downloaded the package from libssh2.org and when I enter: ./buildconf I'm getting:
Neither libtoolize nor glibtoolize could be found!
I don't know what to do, I have included in the header libssh2.h ( #include ) and also the file does exists in the same folder where I have the source file what I'm trying to compile.
It is provided by the package libtool.
On Ubuntu you'd simply
sudo apt-get install libtool
see also http://manpages.ubuntu.com/manpages/dapper/man1/libtoolize.1.html

I am trying to compile google/woff2 for 3 days but getting error "libbrotli needed". I was able compile brotli by running CMakeLists.txt in brotli folder and got .so files. I am beginner so I don't know to link both together. I want to compile and add brotli from CMakeLists.txt in woff2 folder or at least somehow compile linux build for woff2.
Thanks
It seems like you need to compile and install brotli on your machine before you can compile google/woff2. The installation process is actually copying the .so and header file to somewhere on your system path that CMake is able to find it.
For example, you can you use this command to install the library to "/home/myuser/installdir"
cmake --install . --prefix "/home/myuser/installdir"
Build woff2 with libbrotli included in the executable
woff2/README.md says:
git clone --recursive https://github.com/google/woff2.git && cd woff2/ && make clean all
I.e. the woff2 executable´s can be built and used in the woff2/ directory, or can be copied to any location.
cd new-Folder/
git clone --recursive
https://github.com/google/woff2.git
cd woff2/
make clean all ## brotli libs and woff2 are built ... together
## executable: {woff2_compress, woff2_decompress, woff2_info}
## compress example
./woff2_compress satluj.ttf
Processing satluj.ttf => satluj.woff2
Compressed 45526 to 21423.
P.S.: Many of the "Linux OS" have woff2 (and libbrotli) available as a package, name = woff2 or woff2-tools.
I use gsl.
After I compiled my .cpp file and run it, I faced with below error:
error while loading shared libraries: libgsl.so.0: cannot open shared object file: No such file or directory
I found same as this problem in:
https://groups.google.com/forum/#!topic/cortex_var/6vluX7pP0Sk
&
Linux error while loading shared libraries: cannot open shared object file: No such file or directory
&
http://www.gnu.org/software/gsl/manual/html_node/Shared-Libraries.html
And I have done as in the above links wrote but the error is still remained.
Can anyone help me?
To make it work do the following steps
Start Borne Shell
$LD_LIBRARY_PATH= path to your gsl lib folder inside the gsl installation folder
$export LD_LIBRARY_PATH
now run your executable
It should work fine.
First, you need to locate the file (libgsl.so.0). You can do this, for example, by using the find command:
sudo find / -name "libgsl.so.0"
Let us assume, the file is located in /usr/local/lib.
(If the file has not been found, install the corresponding package or download the source, build it and install it.)
Now, you have two options:
(1) Quick & Dirty:
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export LD_LIBRARY_PATH
This adds the path of the library to an environment variable. The disadvantage of this option is, that it is only valid for the current session. It will not work for other users. It will not work once you log off and on again.
(2) Permanent:
Review your /etc/ld.so.conf. If /usr/local/lib is not listed there, add it. Now, run ldconfig to detect the shared object file and add it to some system-wide index.
I got the same error with Krita on Arch Linux. I made a symlink with
ln /usr/lib/libgsl.so /usr/lib/libgsl.so.0
and that fixed it.
In my experience, fastStructure depends on gsl 1.6 but not the latest version.
wget http://gnu.mirror.vexxhost.com/gsl/gsl-1.6.tar.gz
tar -zxvf gsl-1.6.tar.gz
cd gsl-1.16
./configure
make
sudo make install
Add these lines to your .bashrc file on your home directory.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib
export CFLAGS="-I/usr/local/include"
export LDFLAGS="-L/usr/local/lib"
then, run source ~/.bashrc to set these environment variables.
It works fine when I change the version from the latest to the 1.6.
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/home/shg047/software/gsl/lib/
such as: to-mr: error while loading shared libraries: libgsl.so.19: cannot open shared object file: No such file or directory
Have you tried updating your library? The program I was trying to run simply needed a newer version of gsl (I had 1.9.5 while it needed 2.0.0 or newer).
If you are on arch you can run:
yaourt gsl
and select the appropriate one.
You can use gsl-config --libs in you makefile or in the command line when you link the gsl library. Just type gsl-config you can find the options it offers to you. Choose the options you need, you will find compile and link process much easier than before. As a result, when I type gsl-config --libs in my terminal, I get -L/usr/local/lib -lgsl -lgslcblas -lm. Although it is very simple, first you should know where you gsl is installed. You can add the directory to the PATH environment variable or use the absolute path to execute gsl-config .
I needed libgsl.so.19:
/snap/inkscape/current/bin/inkscape: error while loading shared libraries: libgsl.so.19: cannot open shared object file: No such file or directory
I solved it with:
Installing Anaconda
searched for libgsl.so.19 and found it in ~/anaconda3/lib
run LD_LIBRARY_PATH=$LD_LIBRARY_PATH:~/anaconda3/lib (best add it to ~/.basrc)
I tried to install MySQL5.6.16 on Oracle Linux, my source package is mysql-advanced-5.6.16-linux-glibc2.5-x86_64.tar.gz.
I use commond tar to unzip my mysql package.
tar -zvxf mysql-advanced-5.6.16-linux-glibc2.5-x86_64.tar.gz
I use cd to enter the folder mysql-advanced-5.6.16-linux-glibc2.5-x86_64
I use commond cmake .
Then, there was an
CmakeError:the source directory . does not appear to contain cmakelist.txt
Who can tell me why?
PS: I searched the error, somebody said that maybe the source package is not the right one. If so, which package should I download?
I have installed libusb by using the following command. I am not sure if it was right or not and the command was
sudo apt-get install libusb-dev
Once I have installed (and I am not sure if it has installed or not because I am a novice user of Ubuntu), I want to know how would I use the library, because I write some sample code which uses <libusb.h>, but when I compile that C++ file using
g++ test_libusb.cpp
that throws the following error,
test_libusb.cpp:2:20: fatal error: libusb.h: No such file or directory compilation terminated.
I am clueless what to do. I can't find any source on the Internet to get to the bottom of this...
I want to know two things here:
How do I add the libusb library in C/C++ so I can use <libusb.h>?
What would some sample code be? Only a few lines to see if libusb is working...
Try including it like so:
#include <libusb-1.0/libusb.h>
and then compile it like so:
g++ main.cpp -o main -lusb-1.0
Have a look at http://packages.debian.org/wheezy/i386/libusb-dev/filelist: The file you want to include is usb.h. Also, you'll have to tell the compiler where it can find the compiled library functions: Add -lusb to the compiler command line to make it load libusb.so.
Actually at least in Debian 7.4 (wheezy), and probably in Ubuntu also, there are two distinct libusb packages: libusb-dev (0.1.12-20+nmu1) and libusb-1.0-0-dev (1.0.11-1). Confusingly, they can both be installed concurrently and provide header files in different locations:
$ dpkg -L libusb-dev|grep /usr/include
/usr/include
/usr/include/usb.h
$ dpkg -L libusb-1.0-0-dev|grep /usr/include
/usr/include
/usr/include/libusb-1.0
/usr/include/libusb-1.0/libusb.h
Try #include <usb.h>. The "lib" is part of the Linux naming convention, i.e. library "foo" has header foo.h and is called libfoo-dev in the Debian package structure, and linked as -lfoo, and the compiled library files are called libfoo.a and libfoo.so.
Recently, I try to create an makefile as below:
all:
g++ test.cpp -o Test
It creates an runnable Test. However, If I try to link it to an library (as LibCurl to use SSL connetion):
all:
g++ test.cpp -o Test -lcurl
It goes wrong (I already installed libcurl4-openssl-dev package as standard library)!
What does I miss? Can you give any solution? Thanks!!
Edit: The error is below:
fatal error: curl.h: No such file or directory
I guess, you need fix your sources:
#include <curl/curl.h>
The header files are missing in the include search path.
You will have install the development package of libcurl.
For example, install libcurl-devel-7.19.0-11.1.x86_64.rpm for Open Suse 11.1.
To know the list of files that would be installed by the rpm, download the rpm, type the following command in the downloaded dir.
rpm -qlp <rpmname>
As per the example above, the command would be
rpm -qlp libcurl-devel-7.19.0-11.1.x86_64.rpm
This will list the files along with the path in which it would be installed to.
In our example, the result would look like..
/usr/include/curl /usr/include/curl/curl.h /usr/include/curl/curlbuild.h
/usr/include/curl/curlrules.h
/usr/include/curl/curlver.h and so on...
and
Install the development libcurl package for the version of linux you use and include #include <curl/curl.h> in your code.
